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 (5p A), low quiescent currrent (220µA/ channel), and high open-loop gain (94d B). Either single (+4.5V to +36V) or dual (±2.25 to ±18V) supplies can be used. The input mon-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 bination of high slew rate (3.5V/µs) and wide bandwidth (1MHz) provide fast settling time assuring good dynamic response. Dual and quad designs feature pletely 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) es in the miniature MSOP-8 surface mount, SO-8 surface mount, and 8-pin DIP packages. 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 macromodel is available for design analysis.
