Product Summary
The OPA137NA FET-input operational amplifier is designed for low cost and miniature applications. In addition to small size (SOT-23-5 and MSOP-8 packages), the OPA137NA provides low input bias current (5pA), low quiescent currrent (220μA/channel), and high open-loop gain (94dB). Either single (+4.5V to +36V) or dual (±2.25 to ±18V) supplies can be used. The input common-mode voltage range of the OPA137NA includes the positive supply—suitable for many single-supply applications. Single, dual, and quad versions have identical specifications for maximum design flexibility. The applications of the OPA137NA include (1)strain gage amplifier; (2)photodetector amplifier; (3)precision integrator; (4)battery-powered instruments; (5)test equipment; (6)active filters.
