The combination of low offset, low noise, very low 3 +IN A AD8694 12 +IN D input bias currents, and high speed make these amplifiers useful TOP VIEW 4 V+ 11 V (Not to Scale) in a wide variety of applications. Filters, integrators, photodiode 5 +IN B 10 +IN C amplifiers, and high impedance sensors all benefit from this 6 9 IN B IN C combination of performance features. Audio and other ac OUT B 7 8 OUT C applications benefit from the wide bandwidth and low distortion of these devices. Figure 4. 14-Lead SOIC and 14-Lead TSSOP 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 range of 40C to +125C. The AD8691 single is available in 5-lead SC70 and 5-lead TSOT packages. The AD8692 dual is available in 8-lead MSOP and narrow SOIC surface-mount packages. The AD8694 quad is available in 14-lead TSSOP and narrow 14-lead SOIC packages.
