OPA137 series FET-input operational amplifiers are designed for low cost and miniature applications. In addition to small size (SOT-23-5 and MSOP-8 packages), they provide 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 includes the positive supply—suitable for many single-supply applications. Single, dual, and quad versions have
This document is a datasheet for the Burr-Brown OPA137 series of FET-input operational amplifiers, available in single (OPA137), dual (OPA2137), and quad (OPA4137) configurations. Designed for low-cost and miniature applications, these devices feature low input bias current (5pA), low offset voltage (1.5mV), and a wide supply range from +2.25V to +36V. They are offered in various packages including SOT-23-5, MSOP-8, SO-8, SO-14, and DIP formats.
