supply, precision analog-to-digital converters (ADCs)

and digital-to-analog converters (DACs).

Input Voltage Range Includes V– Supply

The OPA140 achieves 11-MHz unity-gain bandwidth

and 20-V/

μs slew rate while consuming only 1.8 mA

•

Single-Supply Operation: 4.5 V to 36 V

(typical) of quiescent current. It runs on a single 4.5-V

•

Dual-Supply Operation: ±2.25 V to ±18 V

to 36-V supply or dual ±2.25-V to ±18-V supplies.

•

No Phase Reversal

All versions are fully specified from –40°C to 125°C
