OPA234 OPA2234 OPA234 OPA234 OPA2234 OPA4234 OPA4234 SBOS055B – MAY 1996 – REVISED APRIL 2008 Low-Power, Precision SINGLE-SUPPLY OPERATIONAL AMPLIFIERS FEATURES OPA234 (cid:1) WIDE SUPPLY RANGE: Offset Trim 1 8 NC Single Supply: V = +2.7V to +36V S ± ± –In 2 7 V+ Dual Supply: V = 1.35V to 18V S (cid:1) SPECIFIED PERFORMANCE: +In 3 6 Output ± +2.7V, +5V, and 15V V– 4 5 Offset Trim (cid:1) LOW QUIESCENT CURRENT: 250µA/amp SO-8, MSOP-8 (cid:1) LOW INPUT BIAS CURRENT: 25nA max (cid:1) LOW OFFSET VOLTAGE: 100µV max (cid:1) HIGH CMRR, PSRR, and A OL (cid:1) SINGLE, DUAL, and QUAD VERSIONS OPA2234 DESCRIPTION The OPA234 series low-cost op amps are ideal for Out A 1 8 V+ single-supply, low-voltage, low-power applications. The –In A 2 A 7 Out B series provides lower quiescent current than older B +In A 3 6 –In B “1013”-type products and comes in current industry- standard packages and pinouts. The combination of V– 4 5 +In B low offset voltage, high common-mode rejection, high power-supply rejection, and a wide supply range pro- SO-8 vides excellent accuracy and versatility. Single, dual, and quad versions have identical specifications for maximum design flexibility. These general-purpose op amps are ideal for portable and battery-powered appli- cations. OPA4234 The OPA234 series op amps operate from either single or dual supplies. In single-supply operation, the input Out A 1 14 Out D common-mode range extends below ground and the output can swing to within 50mV of ground. Excellent –In A 2 13 –In D A D phase margin makes the OPA234 series ideal for de- +In A 3 12 +In D manding applications, including high load capacitance. Dual and quad designs feature completely indepen- V+ 4 11 V– dent circuitry for lowest crosstalk and freedom from +In B 5 10 +In C interaction. B C –In B 6 9 –In C Single version packages are in an SO-8 surface-mount and a space-saving MSOP-8 surface-mount. Dual pack- Out B 7 8 Out C ages are in an SO-8 surface-mount. Quad packages SO-14 are in an SO-14 surface-mount. All are specified for –40°C to +85°C operation.

Use offset adjust pins only to null Power-supply pins should be bypassed with 10nF ceramic 7 offset voltage of op amp—see text. 2 capacitors. 6 OPA234 3 5 OPERATING VOLTAGE 1 The OPA234 series op amps operate from single (+2.7V to 10nF 4 100kΩ +36V) or dual (±1.35V to ±18V) supplies with excellent Trim Range: ±4mV typ performance. Specifications are production tested with +2.7V, +5V, and ±15V supplies. Most behavior remains unchanged (V–) = 0V for single supply operation. V– throughout the full operating voltage range. Parameters which vary significantly with operating voltage are shown in the Typical Characterisitc curves. FIGURE 1. OPA234 Offset Voltage Trim Circuit. OFFSET VOLTAGE TRIM Offset voltage of the OPA234 series amplifiers is laser trimmed and usually requires no user adjustment. The OPA234 (single op amp version) provides offset voltage trim connections on pins 1 and 5. Offset voltage can be adjusted by connecting a potentiometer, as shown in Fig- ure 1. This adjustment should be used only to null the offset of the op amp, not to adjust system offset or offset pro- duced by the signal source. Nulling offset could degrade the offset drift behavior of the op amp. While it is not possible to predict the exact change in drift, the effect is usually small.
