3 Description

The OPA2156 is the first in a planned new generation

of 36-V, rail-to-rail operational amplifiers (op amps).

This devices offers very low offset voltage (±25 μV),

drift (±0.5 μV/°C), and low bias current (±5 pA)

combined with very low broadband voltage noise (3

nV/√Hz) .

Unique features, such as rail-to-rail input and output

voltage ranges, wide bandwidth (25 MHz) high output

current (100 mA), and high slew rate (40 V/μs) make

the OPA2156 a robust, high-performance operational

amplifier for high-voltage precision industrial

applications.

The OPA2156 op amp is available in 8-pin SOIC and

VSSOP packages and is specified over the industrial

temperature range of –40°C to +125°C.
