DESCRIPTION

The OPA743 series utilizes a state-of-the-art 12V analog

CMOS process and offers outstanding AC performance,

such as 7MHz GBW, 10V/μs slew rate and 0.0008% THD+N.

Optimized for single supply operation up to 12V, the input

common-mode range extends beyond the power supply rails

and the output swings to within 100mV of the rails. The low

quiescent current of 1.1mA makes it well suited for use in

battery operated equipment.

The OPA743 series’ ability to drive high output currents

together with 12V operation makes it particularly useful for

use as gamma correction reference buffer in LCD panels.

For ease of use the OPA743 op-amp family is fully specified

and tested over the supply range of ±1.75V to ±6V. Single,

dual and quad versions are available.

The single versions (OPA743) are available in the MicroSIZE

SOT23-5 and in the standard SO-8 surface-mount, as well as

DIP-8 packages. Dual versions (OPA2743) are available versions

in the MSOP-8, SO-8, and DIP-8 packages. The quad

versions (OPA4743) are available in the TSSOP-14 and SO-14

packages. All are specified for operation from –40°C to +85°C.
