7.4.2 Single-Supply Operation (4.75V to 27V)

Many newer systems use a single power supply to improve efficiency and reduce the cost of the extra power supply. The OPA810-Q1 can be used with a single supply (with the negative supply set to ground) with no change in performance if the input and output are biased within the linear operation of the device. To change the circuit from split supply to a balanced, single-supply configuration, level shift all voltages by half the difference between the power-supply rails. An additional advantage of configuring an amplifier for single-supply operation is that the effects of PSRR are minimized because the low-supply rail is grounded. See the Single-Supply Op Amp Design Techniques application report for examples of single-supply designs.
