Description for the OPA2137
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), amplifiers provide low input bias current (±10pA), low quiescent current (120µA/ channel), and high open-loop gain (145dB).
Either single (+4.5V to +36V) or dual (±2.25V to ±18V) supplies can be used. The input common-mode voltage range includes the positive supply an excellent choice 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 the specified limits. In addition, the combination of high slew rate (4.5V/µs) and wide bandwidth (1.1MHz) provide fast settling time verifies 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 surface mount, SO-8 surface mount, and 8-pin DIP. The dual (OPA2137) comes in the miniature MSOP-8 surface mount, and the SO-8 surface mount. The quad (OPA4137) packages are the SO-14 surface mount and the 14-pin DIP. All are specified from – 40°C to +85°C and operate from – 55°C to +125°C. A SPICE macro-model is available for design analysis.
