APPLICATIONS
Photodiode amplification Battery-powered instrumentation Medical instruments Multipole filters Sensors Portable audio devices
GENERAL DESCRIPTION
The AD8691, AD8692, and AD8694 are low cost, single, dual, and quad rail-to-rail output, single-supply
amplifiers featuring low offset and input
voltages, low current noise, and wide signal bandwidth. The combination of low offset, low noise, very low input bias currents, and high speed make these
amplifiers useful in a wide variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from this combination of performance features. Audio and other ac applications benefit from the wide bandwidth and low distortion of these devices.
Applications for these
amplifiers include power amplifier (PA) controls, laser diode control loops, portable and loop-powered instrumentation, audio amplification for portable devices, and ASIC input and output
amplifiers.
The small SC70 and TSOT package options for the AD8691 allow it to be placed next to sensors, thereby reducing external noise pickup.
The AD8691, AD8692, and AD8694 are specified over the extended industrial temperature r...
