The OPA659 is intended for operation on ±6-V supplies. Single-supply operation is allowed with minimal change from the stated specifications and performance from a single supply of 7 V to 13 V maximum. The limit to lower supply voltage operation is the useable input voltage range for the JFET-input stage. Operating from a single supply can have numerous advantages. With the negative supply at ground, the DC errors due to the –PSRR term can be minimized. Typically, AC performance improves slightly at 13-V operation with minimal increase in supply current.
