This datasheet introduces the features and characteristics of OPA137, OPA2137, OPA4137. They 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
The document describes the OPA137 series of low-cost, FET-input operational amplifiers available in single, dual, and quad configurations. These devices are designed for miniature applications and feature low input bias current, low offset voltage, and a wide supply voltage range. The series includes the OPA137 (single), OPA2137 (dual), and OPA4137 (quad) models.
