Product Summary
The OPA137UA 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 OPA137UA provides low input bias current (5pA), low quiescent currrent (220mA/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 OPA137UA includes the positive supply—suitable for many single-supply applications. Single, dual, and quad versions have identical specifications for maximum design flexibility. The OPA137UA op amp is easy to use and free from phase inversion and overload problems found in some FET-input amplifiers. High performance, including linearity, is maintained as the amplifiers swing to their specified limits. In addition, the combination of high slew rate (3.5V/ms) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response.
