Lowest power zero crossover op amp
Said to be the industry’s lowest power zero crossover op amp, the OPA369 from Texas Instruments achieves rail to rail performance without input crossover, solving the common design problem of input offset distortion due to the change in common mode voltage.
“The OPA369 uses TI’s innovative zero crossover topology and next generation cmos process technology to offer precision performance previously unavailable in 1µA single supply amplifiers,” said Art George, senior vice president of TI’s high performance analogue business. “Typically, designers are forced to choose between power consumption and the ac or dc performance of their signal conditioning amplifiers. The OPA369 will enable customers to increase the precision in their portable applications without complicating the design or increasing their power budget.”
The single input stage architecture delivers an offset voltage of 750µV over the rail to rail input range and a common mode rejection ratio of at least 100dB.
