GENERAL DESCRIPTION
The AD8692 is a low cost, dual rail-to-rail output, single-supply
amplifier featuring low offset voltage, low input voltage and
current noise, and wide signal bandwidth. The combination of
low offset, low noise, very low input bias currents, and high
speed makes this amplifier useful in a wide variety of applica-
tions. Filters, integrators, photodiode amplifiers, and high
impedance sensors all benefit from the combination of
performance features. Audio and other ac applications benefit
from the wide bandwidth and low distortion.
Applications for this amplifier include PA controls, laser diode
control loops, portable and loop-powered instrumentation,
audio amplification for portable devices, and ASIC input and
output amplifiers.
The AD8692 is specified over the extended industrial tempera-
ture range of −40°C to +125°C. The AD8692 is available in the
micro-SOIC and 8-lead narrow SOIC surface-mount packages.
