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.

REVISION HISTORY

ELECTRICAL CHARACTERISTICS VS = 2.7 V, VCM = VS/2, TA = 25°C, unless otherwise noted.
Table 1. VS = 5.0 V, VCM = VS/2, TA = 5°C, unless otherwise noted.
Table 2. ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted.
Table 3. 1 θJA is specified for the worst-case conditions, that is, the device soldered in
the circuit board for surface-mount packages.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL CHARACTERISTICS
Table 4.
ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
TYPICAL PERFORMANCE CHARACTERISTICS VS = +5 V or ±2.5 V.
