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 range of −40°C to +125°C.
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.
