OPA2140AIDGKR

Description
The OPA140, OPA2140, and OPA4140 (OPAx140) 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-torail output swing and input range that includes V– allow designers to take advantage of the lownoise characteristics of JFET amplifiers while also interfacing to modern, single-supply, precision analogto-digital converters (ADCs) and digital-to-analog converters (DACs).
The OPA140 achieves 11-MHz unity-gain bandwidth and 20-V/μs slew rate while consuming only 1.8 mA (typical) of quiescent current. This device runs on a single 4.5-V to 36-V supply or dual ±2.25-V to ±18-V supplies.
