DESCRIPTION
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 identical specifications for maximum design flexibility. OPA137 op amps are 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/µs) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. The single (OPA137) packages are the tiny 5-lead SOT-23-5 surfa...
