SBOS498E – JULY 2010 – REVISED JULY 2021

OPAx140 High-Precision, Low-Noise, Rail-to-Rail Output, 11-MHz, JFET Op Amp

1 Features

3 Description

•

Very-low offset drift: 1 μV/°C maximum

Very-low offset: 120 μV

Low input bias current: 10 pA maximum

Very-low 1/f noise: 250 nV_PP, 0.1 Hz to 10 Hz

Low noise: 5.1 nV/√Hz

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-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).

Slew rate: 20 V/μs

Low supply current: 2 mA maximum

Input voltage range includes V– supply

Single-supply operation: 4.5 V to 36 V

Dual-supply operation: ±2.25 V to ±18 V

No phase reversal

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.

Packages:

– Industry-standard SOIC, SON (Preview),

SOT-23, TSSOP, and VSSOP

2 Applications

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

for use in the most challenging environments. The

OPA140 (single) is available in the 5‑pin SOT-23 8‑pin

VSSOP and 8‑pin SOIC packages. The OPA2140

(dual) is available in 8‑pin SON, 8‑pin VSSOP,

and 8‑pin SOIC packages. The OPA4140 (quad) is

available in the 14‑pin SOIC and 14‑pin TSSOP

packages.
