Op amp

Staff -- Test & Measurement World, 9/1/2006

Texas Instruments has introduced a precision op amp that uses a zero-crossover, single-input-stage architecture to achieve glitchless rail-to-rail performance. Featuring distortion of 0.0006% THD+N, low noise of 4.5 nV/√Hz, and gain bandwidth of 50 MHz, the OPA365 serves a variety of single-supply portable-instrumentation, data-acquisition, test-and-measurement, and audio applications.

The single-stage input topology reduces distortion and delivers common-mode rejection ratio of 100 dB minimum and 120 dB typical over the entire input range (100 mV beyond the supply rails), making it suitable for driving analog-to-digital converters without degradation of differential linearity. Other features include fast settling time of 300 ns to 0.01%, offset voltage of 200 µV maximum, and single-supply operation from 2.2 V to 5.5 V.
