•

Very Low Offset Drift: 1mV/°C max

The OPA140, OPA2140, and OPA4140 op amp

family is a series of low-power JFET input amplifiers

•

Very Low Offset: 120mV

that feature good drift and low input bias current. The

•

Low Input Bias Current: 10pA max

rail-to-rail output swing and input range that includes

•

V–

allow

designers

to

take

advantage

of

the

•

Low Noise: 5.1nV/

√Hz

low-noise characteristics of JFET amplifiers while

also interfacing to modern, single-supply, precision

•

Slew Rate: 20V/ms

analog-to-digital

converters

(ADCs)

and

•

Low Supply Current: 2.0mA max

digital-to-analog converters (DACs).

•

Input Voltage Range Includes V– Supply

The OPA140 achieves 11MHz unity-gain bandwidth

•

Single-Supply Operation: 4.5V to 36V

and 20V/ms slew rate while consuming only 1.8mA

•

Dual-Supply Operation: ±2.25V to ±18V

(typ) of quiescent current. It runs on a single 4.5 to

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

•

No Phase Reversal

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