AD8210 Data Sheet THEORY OF OPERATION In typical applications, the AD8210 amplifies a small differential The differential currents through Q1 and Q2 are converted input voltage generated by the load current flowing through a into a differential voltage by R3 and R4. A2 is configured as an shunt resistor. The AD8210 rejects high common-mode voltages instrumentation amplifier. The differential voltage is converted (up to 65 V) and provides a ground referenced buffered output into a single-ended output voltage by A2. The gain is internally that interfaces with an analog-to-digital converter (ADC). set with precision-trimmed, thin film resistors to 20 V/V. Figure 26 shows a simplified schematic of the AD8210. The output reference voltage is easily adjusted by the V 1 pin REF The AD8210 is comprised of two main blocks, a differential and the V 2 pin. In a typical configuration, V 1 is connected REF REF amplifier and an instrumentation amplifier. A load current to V while V 2 is connected to GND. In this case, the output CC REF flowing through the external shunt resistor produces a voltage is centered at VCC/2 when the input signal is 0 V. at the input terminals of the AD8210. The input terminals are connected to the differential amplifier (A1) by R1 and R2. A1 nulls the voltage appearing across its own input terminals by adjusting the current through R1 and R2 with Q1 and Q2. When the input signal to the AD8210 is 0 V, the currents in R1 and R2 are equal. When the differential signal is nonzero, the current increases through one of the resistors and decreases in the other. The current difference is proportional to the size and polarity of the input signal. ISHUNT RSHUNT R1 R2 VS AD8210 A1 VREF1 Q1 Q2 VOUT=(ISHUNT×RSHUNT)×20 A2 R3 R4 VREF2 GND 05147-004 Figure 26.

Data Sheet AD8210 MODES OF OPERATION The AD8210 can be adjusted for unidirectional or bidirectional V+ Referenced Output operation. This mode is set when both reference pins are tied to the UNIDIRECTIONAL OPERATION positive supply. It is typically used when the diagnostic scheme requires detection of the amplifier and wiring before power is Unidirectional operation allows the AD8210 to measure applied to the load (see Figure 28 and Table 5). currents through a resistive shunt in one direction. The basic modes for unidirectional operation are ground referenced RS output mode and V+ referenced output mode. +IN –IN In unidirectional operation, the output can be set at the negative rail (near ground) or at the positive rail (near V+) when the VS differential input is 0 V. The output moves to the opposite rail when a correct polarity differential input voltage is applied. In AD8210 this case, full scale is approximately 250 mV. The required 0.1µF polarity of the differential input depends on the output voltage setting. If the output is set at ground, the polarity needs to be VREF1 positive to move the output up (see Table 5). If the output is set at the positive rail, the input polarity needs to be negative to OUTPUT G=+20 move the output down (see Table 6). Ground Referenced Output When using the AD8210 in this mode, both reference inputs VREF2 are tied to ground, which causes the output to sit at the negative rail when the differential input voltage is zero (see Figure 27 GND and Table 4). 05147-006 RS Figure 28.

In some cases, however, it is set at a voltage other than half scale when the bidirectional current is nonsymmetrical. VREF2 Table 6.

When the input is negative VS 0.1µF relative to the −IN pin, the output moves down from the reference voltage. When the input is positive relative to the AD8210 −IN pin, the output increases.

Split External Reference Splitting the Supply VREF2 By tying one reference pin to V+ and the other to the GND pin, the output is set at midsupply when there is no differential input GND (see Figure 31).

For example, In this case, an external reference is divided by two with if the supply is 5.0 V, the output is at half scale or 2.5 V. If the an accuracy of approximately 0.2% by connecting one supply increases by 10% (to 5.5 V), the output also increases by V pin to ground and the other V pin to the reference 10% (2.75 V).

There is no operational difference between the pins. VS For proper operation, the AD8210 output offset must not be set with a resistor voltage divider. Any additional external AD8210 resistance could create a gain error. A low impedance voltage 0.1µF source must be used to set the output offset of the AD8210.

This causes the common-mode ured because the shunt remains in the loop when the switch is voltage to increase to the battery voltage. In this case, when the off. In addition, diagnostics can be enhanced because short circuits switch is opened, the voltage reversal across the inductive load to ground can be detected with the shunt on the high side. causes the common-mode voltage to be held one diode drop 5V below ground by the clamp diode. INDUCTIVE 0.1µF H-BRIDGE MOTOR CONTROL CLAMP LOAD DIODE Another typical application for the AD8210 is as part of the control loop in H-bridge motor control. In this case, the AD8210 BATTERY +IN VREF1 +VS OUT is placed in the middle of the H-bridge (see Figure 35) so that it SHUNT AD8210 can accurately measure current in both directions by using the –IN GND VREF2 NC shunt available at the motor. This configuration is beneficial for measuring the recirculation current to further enhance the SWITCH control loop diagnostics. NC= NOCONNECT 05147-010 5V0.1µF Figure 33. Low-Side Switch CONTROLLER In this circuit configuration, when the switch is closed, the common-mode voltage moves down to the negative rail. When MOTOR +IN VREF1 +VS OUT the switch is opened, the voltage reversal across the inductive AD8210 SHUNT load causes the common-mode voltage to be held one diode –IN GND VREF2 NC 5V drop above the battery by the clamp diode. HSWIGIHTC-SHID E CURRENT SENSE WITH A HIGH-SIDE NC=NOCONNECT 2.5V 05147-012 This configuration minimizes the possibility of unexpected Figure 35. Motor Control Application solenoid activation and excessive corrosion (see Figure 34). In The AD8210 measures current in both directions as the H-bridge this case, both the switch and the shunt are on the high side. switches and the motor changes direction. The output of the When the switch is off, the battery is removed from the load, AD8210 is configured in an external reference bidirectional which prevents damage from potential short circuits to ground, mode (see the Modes of Operation section). while still allowing the recirculation current to be measured and diagnostics to be performed. Removing the power supply from the load for the majority of the time minimizes the corrosive effects that could be caused by the differential voltage between the load and ground. Rev.
