The TLV9004SIRTER with Operational Amplifiers Op Amps 4-Channel, 1MHz, RRIO, 1.8V to 5.5V Operational Amplifier for Cost-Optimized Systems 16-WQFN -40 to 125 is an advanced, cost-optimized operational amplifier (Op Amp) manufactured by Texas Instruments. The Op Amp is designed to operate from a wide input voltage range of 1.8 V to 5.5 V, and it comes in a low-profile, quad-channel 16-WQFN package with an operating temperature range of -40 to 125 °C. It has a wide operating bandwidth of 1 MHz and features a high level of gain accuracy with a Rail-to-Rail input output capability (RRIO). The device also uses Extremely Low Noise (ELN) technology to provide superior system signal-to-noise ratio performance.
