The AD8646 and AD8648 are available for voltage, and low current noise. The AD8647 also has a low automotive applications (see the Ordering Guide). power shutdown function. Applications include portable and low powered instrumenta- The combination of 24 MHz bandwidth, low offset, low noise, tion, audio amplification for portable devices, portable phone and very low input bias current makes these amplifiers useful in headsets, barcode scanners, and multipole filters. The ability to a wide variety of applications. Filters, integrators, photodiode swing rail to rail at both the input and output enables designers amplifiers, and high impedance sensors all benefit from the to buffer CMOS ADCs, DACs, ASICs, and other wide output combination of performance features. AC applications benefit swing devices in single-supply systems. from the wide bandwidth and low distortion. The AD8646/ Rev.

Data Sheet AD8646/AD8647/AD8648 THEORY OF OPERATION POWER-DOWN OPERATION The shutdown function of the AD8647 is referenced to the 2V negative supply voltage of the operational amplifier. A logic 1V level high (> 2.0 V) enables the device, while a logic level low (< 0.8 V) disables the device and places the output in a high 0V impedance condition. Several outputs can be wire-OR’ed, thus eliminating a multiplexer. The logic input is a high impedance CMOS input. If dual or split supplies are used, the logic signals must be properly referred to the negative supply voltage. 5V MULTIPLEXING OPERATION 0V Because each op amp has a separate logic input enable pin, the oonutlyp uotnse c oapn abme pco ins nacetcitveed a tto agneyt htiemr eif. iBt yc acnon bnee gcutianrga tnhtee eodp t ahmatp s TIME (200µs/DIV) 06527-050 Figure 49. Switching Waveforms as shown in Figure 48, a multiplexer can be eliminated. With the reasonably short turn-on and turn-off times, low frequency signal paths can be smoothly selected. The turn-off time is 80 slightly faster than the turn-on time so, even when using 70 sections from two different packages, the overlap is less than 300 nanoseconds. 60 A) µ 50 1/2 T ( 8 AD8647 REN 40 9 R U 7 C 30 6 Y L 5kHz PP 20 5V SU VSY = 5V 10 1/2 AD8647 VSY = 2.7V 0 2 10 13kHz 3 4 5 1 –100 0.1 0.2 0.V3IN_S0D.4A AN0D.5 VIN_0S.D6B (V0).7 0.8 0.9 1.0 06527-051 Figure 50.
