JAJSFO4B August 2017 – December 2018 OPA2810
Many newer systems use a single power supply to improve efficiency and reduce the cost of the extra power supply. The OPA2810 can be used with a single supply (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 the 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.
