TI Unveils Zero-Crossover, Rail-to-Rail Amplifier for High-Performance, Single-Supply Applications

“The OPA365 leverages TI’s expertise in analog signal conditioning to solve the common design challenge of finding an op amp that does not limit the capability of the data converter,” said Art George, senior vice president of TI’s high-performance analog business. “The OPA365’s zero-crossover topology, combined with superior noise and speed performance, solves this design challenge unlike any other amplifier on the market and reinforces TI’s position as the leading supplier of high-performance amplifiers.”

The unique single-stage input topology enables rail-to-rail input without the crossover associated with traditional complementary input stages. This design reduces distortion and delivers outstanding common-mode rejection ratio(CMRR) of 100dB minimum and 120dB typical over the entire input range (100mV beyond the supply rails), making it ideal for driving analog-to-digital converters without degradation of differential linearity. Other features include fast settling time of 300ns to 0.01%, low offset voltage of 200uV maximum and single-supply operation from 2.2V to 5.5V.
