OPA2156 36 V, Low-Noise Precision Rail-to-Rail In/

Texas Instruments' OPA2156 is a 36 V, rail-to-rail op-amp that offers ultra-low offset voltage (±25 µV), drift (±0.5 µV/°C), and low bias current (±5 pA) combined with ultra-low broadband voltage noise (3 nV/√Hz).

The OPA2156 device features rail-to-rail input and output voltage ranges, wide bandwidth (25 MHz), high output current (100 mA), and a high slew rate (40 V/µs) making it a robust, high-performance op-amp for high-voltage precision industrial applications.

The OPA2156 op-amp is available in an 8-pin VSSOP package and is specified over the industrial temperature range of -40°C to +125°C.
