OPA4140 JFET op amp IC Chip

OPA4140（High-precision, low-noise, rail-to-rail output,11-MHz JFET op amp）

Introduction

The OPA140, OPA2140, and OPA4140 operational amplifier (op amp) family is a series of low-power JFET input amplifiers that features 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).

All versions are fully specified from – 40°C to +125°C for use in the most challenging environments. The OPA4140 (quad) is available in the 14-pin SOIC and 14-pin TSSOP packages.
