Overview
The TLV3544-Q1 series of high-speed, voltage-feedback CMOS operational amplifiers (op amps) from Texas Instruments are designed for video and other applications requiring wide bandwidth. These quad-channel op amps are unity-gain stable and can drive large output currents. They are optimized for operation on single or dual supplies ranging from 2.5 V to 5.5 V and are specified over an extended temperature range of –40°C to +125°C. The TLV3544-Q1 is particularly suited for automotive applications and is AEC-Q100 qualified.
