Precision Rail-to-Rail Amplifiers

Rail-to-rail inputs and outputs provide flexibility on the op amps and maximize the dynamic range of the signal chain. R-R inputs allow both high-side and low-side sensing, a wide range of common mode bias arrangements and the widest possible range of input signals from micro-volts to volts. R-R outputs maximize the dynamic range and signal-to-noise ratio for the available supply range and also allow maximum resolution from following converter stages. As either an ADC driver or a DAC buffer, R-R capability maximizes the system performance potential. Analog Devices offers a wide selection of R-R input and output op amps in the industry with the best performance available.
