AD8692ARZ-REEL7

The AD8691, AD8692, and AD8694 are single, dual, and quad, low cost, rail-to-rail output, single-supply amplifiers featuring low offset, low input voltage, low current noise, and wide signal bandwidth. The combination of low offset, low noise, ultralow input bias current, and high speed makes these amplifiers suitable for a wide range of applications. Filters, integrators, photodiode amplifiers, and high impedance sensors can all benefit from this combination of features. Wide bandwidth and low distortion benefit audio and other AC applications. Specific applications for these amplifiers include: power amplifier (PA) control, laser diode control loops, portable and loop-powered instrumentation, audio amplification in portable equipment, and ASIC input and output amplifiers. The AD8691 is available in compact SC70 and TSOT packages, allowing placement close to sensors to minimize the effects of external noise. The AD8691, AD8692, and AD8694 are rated over the -40°C to +125°C extended industrial temperature range. The AD8691 single-channel amplifier is available in 5-lead SC70 and 5-lead TSOT packages. The AD8692 dual amplifier is available in 8-lead MSOP and narrow-body SOIC surface-mount packages. The AD8694 quad amplifier is available in 14-lead TSSOP and 14-lead narrow-body SOIC packages.
