Description

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 A_OL. 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.
