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.
