GENERAL DESCRIPTION
The ADA4691-2/ADA4692-2 are dual and the ADA4691-4/
ADA4692-4 are the quad rail-to-rail output, single-supply
amplifiers featuring low power, wide bandwidth, and low noise.
The ADA4691-2 has two independent shutdown pins, allowing
further reduction in supply current. The ADA4691-4 is a quad
with dual shutdown pins each controlling a pair of amplifiers
and is available in the 16-lead LFCSP. The ADA4692-4 is a quad
version without shutdown.
These amplifiers are ideal for a wide variety of applications.
Audio, filters, photodiode amplifiers, and charge amplifiers, all
benefit from this combination of performance and features.
Additional applications for these amplifiers include portable
consumer audio players with low noise and low distortion that
provide high gain and slew rate response over the audio band at
low power. Industrial applications with high impedance sensors,
such as pyroelectric and IR sensors, benefit from the high
impedance and low 0.5 pA input bias, low offset drift, and
enough bandwidth and response for low gain applications.
The ADA4691/ADA4692 family is fully specified over the extended
industrial temperature range (40°C to +125°C). The ADA4691-2
is available in a 10-lead LFCSP and a 9-ball WLCSP. The ADA4692-2
is available in an 8-lead SOIC and 8-lead LFCSP. The ADA4691-4 is
available in a 16-lead LFCSP. The ADA4692-4 is available in a 14-lead
TSSOP. For pin configurations, see the Pin Configurations section.
