The TLV2721CDBVR is a single rail-to-rail output CMOS operational amplifier from Texas Instruments in SOT-23-5, operating from 2.7V to 5.5V with 3MHz gain-bandwidth product. This is the standard SOT-23-5 version of the TLV2721 (compared to the SOT-23-8 variant TLV2721CDBVT which has extra NC pins but identical functionality). The CMOS input stage provides extremely low input bias current of 1pA typical and input offset voltage of 500uV typical. The rail-to-rail output swings to within 10mV of the rails with a 10k-ohm load. The supply current is 550uA per amplifier. The 3MHz GBW and 2.4V/us slew rate support active filters and signal conditioning up to 300kHz. The input common-mode range extends from the negative rail to V+ – 1.2V. The device is unity-gain stable and internally compensated. The output can source/sink 10mA at 5V supply. The low input bias current makes it ideal for photodiode transimpedance amplifiers, pH sensor interfaces, and other high-impedance sources. The commercial temperature range is 0C to +70C. The device is a cost-effective alternative to bipolar op-amps when low input bias current and rail-to-rail output are required.
