INA149AIDR TI Instrumentation, OP Amps, Buffer Amps

The INA149 is a high-common-mode voltage difference amplifier with a fixed gain of 1, operating from a ±2.25-V to ±18-V dual supply (or 4.5-V to 36-V single). It features a wide common-mode voltage range of ±500 V, high input impedance (1 MΩ), and low error (0.01% nonlinearity). Packaged in an 8-pin SOIC (D), it is ideal for precise voltage measurement in high-voltage systems, including battery management systems (BMS) for electric vehicles, power supply monitoring, motor control, and industrial data acquisition.
