The OPA725 and OPA726 series op amps use a state-of-the-art 12V analog CMOS process, and combine outstanding ac performance with low bias current and excellent CMRR, PSRR, and AOL. The 20MHz Gain-Bandwidth GBW Product is achieved by using a proprietary and patent-pending output stage design. These characteristics allow excellent 16-bit settling times for driving 16-bit Analog-to-Digital Converters ADCs.

Excellent ac characteristics, such as 20MHz GBW, 30V/µs slew rate and 0.0003% THD+N make the OPA725 and OPA726 well-suited for communication, high-end audio, and active filter applications. With bias current of less than 200pA, they are well-suited for use as transimpedance I/V-conversion amplifiers for monitoring optical power in ONET applications.

The OPA725 and OPA726 op amps can be used in single-supply applications from 4V up to 12V, or dual-supply from ±2V to ±6V. The output swings to within 150mV of the rails, maximizing dynamic range. The shutdown versions OPAx726 reduce the quiescent current to less than 6µA and feature a reference pin for easy shutdown operation with standard CMOS logic in dual supply applications.

The OPA725 single is available in SOT23-5 and SO-8 [ackages, and the OPA2725 dual is available in MSOP-8 Q1 ’04 and SO-8 packages. The OPA726 single with shutdown is available in MSOP-8 and SO-8. The OPA2726 dual with shutdown is available in MSOP-10. All versions are specified for operation from –40°C to +125°C.
