3 Description

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.
