OPA2156 - 36-V, Ultra-Low Noise, Wide-Bandwidth, Precision Rail-to-Rail Operational Amplifier

The OPA2156 is the first in a planned new generation of 36-V, rail-to-rail operationalamplifiers (op amps).

This devices offers very low offset voltage (±200 µV, maximum), drift (±2 µV/°C,maximum), and low bias current (±5 pA, typical) combined with very low broadband voltage noise (3nV/√Hz) .

Unique features, such as rail-to-rail input and output voltage ranges, wide bandwidth (25MHz) 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 an 8-pin SOIC package and is specified over theindustrial temperature range of –40°C to 125°C.
