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 (2.7 to 5.5V).

These devices were specifically designed to drive typical

headset levels (32Ω), as well as bias RF power amplifi-

ers for wireless handset applications.

The devices are available as the standard products

shown in

page

Table 1. Standard Products

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 ver-

sions) drives the output low.

These devices operate over the entire automotive tem-

perature range (-40°C to +125°C).
