The OPA237UA, released by Texas Instruments, is an operational amplifier IC (Integrated Circuit) in an 8-Pin DIP (Dual In-line Package). It provides high-performance, low-power, low-cost amplifiers with excellent AC characteristics. It belongs to an Operational Amplifier series known as 'Precision Rail-to-Rail'. These Operational Amplifiers are suitable for driving low-power transistors or bipolar op amps, and their features include unity gain stability, low noise, and fast response. The OPA237UA offers excellent common-mode rejection ratio (CMRR) of more than 90dB, along with high power supply rejection ratio (PSRR) at greater than 120dB. It provides operating voltage ranges from ±2V to ±18V, and supports current consumption of 5mA. The OPA237UA has a high Slew Rate of 7.1V/µs. This Operational Amplifier also features a Wide CMRR bandwidth of 9kHz, as well as high Output/input Voltage range of ±2V to ±18V. It is suitable for various applications, such as motor control and battery-powered systems.
