Description

The OPA141, OPA2141, and OPA4141 amplifier family is a series of low-power JFET input amplifiers that feature good drift and low input bias current. The rail-to-rail output swing and input range that includes V– allow designers to take advantage of the low-noise characteristics of JFET amplifiers while also interfacing to modern, single-supply, precision analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). The OPA141 achieves 10MHz unity-gain bandwidth and 20V/µs slew rate while consuming only 1.8mA (typ) of quiescent current. It runs on a single 4.5 to 36V supply or dual ±2.25V to ±18V supplies. All versions are fully specified from –40°C to +125°C for use in the most challenging environments. The OPA141 (single) and OPA2141 (dual) versions are available in both MSOP-8 and SO-8 packages; the OPA4141 (quad) is available in the SO-14 and TSSOP-14 packages.
