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 theMicroSIZE 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.

The OPA2822 offers very low 2.0nV/Hzinput noise in a wideband, unity gain stable, voltage-feedback architecture. Intended for xDSL receiver applications, the OPA2822 also supports this low input noise with exceptionally low harmonic distortion, particularly in differential configurations. Adequate output current is provided to drive the potentially heavy load of a passive filter between this amplifier and the codec.

Operating on a low 4.8mA/ch supply current, the OPA2822 can satisfy all xDSL receiver requirements over a wide range of possible supply voltages—from a single +5V condition, to ±5V, on up to a single +12V design. General-purpose applications on a single +5V supply will benefit from high input and output voltage swing available on this reduced supply voltage. Low-cost precision integrators for PLLs will also benefit from the low voltage noise and offset voltage. Baseband I/Q receiver channels can achieve almost perfect channel match with noise and distortion to support signals through 5MHz with > 14-bit dynamic range.
