The OPA743 series utilizes a state-of-the-art 12V analog CMOS process and offers outstanding AC performance, such as 7MHz GBW, 10V/us 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\x92 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 \x9640°C to +85°C.
