Texas Instruments OPA2156 Precision Operational Amplifier
Texas Instruments OPA2156 Precision Operational Amplifier is the first in the next generation of 36V, rail-to-rail operational amplifiers (op amps). These devices offer very low offset voltage (±200µV, max), drift (±3µV/°C, max), and low bias current (±5pA) combined with very low broadband voltage noise (3nV/√Hz). These op amps have unique features, such as rail-to-rail input and output voltage ranges, wide bandwidth (25MHz), high output current (100mA), and high slew rate (40V/µs). These features make the Texas Instruments OPA2156 a robust, high-performance operational amplifier for high-voltage precision industrial applications.
