AS1710/AS1712
High-Output-Drive, 10MHz, 10V/µs, Rail-to-Rail I/O Op Amps
with Shutdown

Data sheet
1 General Description
The AS1710/AS1712 are low-offset, high-output CMOS op-amps
that deliver 200mA of peak output current from a single supply (2.7V
to 5.5V).
These devices were specifically designed to drive typical headset
levels (32
), as well as bias RF power amplifiers for wireless
handset applications.
The devices are available as the standard products shown in
Table 1. See also Ordering Information on page 18.
These rail-to-rail I/O, wide-bandwidth amplifiers exhibit a high slew
rate of 10V/µs and a gain-bandwidth product of 10MHz.
The integrated shutdown feature (not included in B versions) drives
the output low.
These devices operate over the entire industrial temperature range
(-40ºC to +85ºC).
