The TLV365 and TLV2365 devices (TLVx365) are a family of zero-crossover, rail-to-rail input and output, CMOS operational amplifiers, optimized for low voltage and cost-sensitive applications. Low-noise (4.5nV/√Hz) and high-speed operation (50MHz gain bandwidth) make these devices an excellent choice for driving sampling analog-to-digital converters (ADCs) in applications such as low-side current sensing, audio, signal conditioning, and sensor amplification.

Special features include an excellent common-mode rejection ratio (CMRR), no input stage crossover distortion, high input impedance, and rail-to-rail input and output swing. The input common-mode range includes both the negative and positive supplies. The output voltage swings to within 10mV of the rails.

The TLVx365 are specified for operation from −40°C to +125°C.
