DescriptionThe OPA725 and OPA726 series op amps use astate-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 of OPA725 and OPA726, such as 20MHz GBW, 30V/µs slew rate and 0.0003% THD+N make the OPA725 andAPPLICATIONS OPA726 well-suited for communication, high-end audio,and active filter applications. With a 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 within150mV 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 indual-supply applications
