10 Power Supply Recommendations

The OPA656 is intended for operation on ±5-V supplies. Single-supply operation is allowed with minimal change

from the stated specifications and performance from a single supply of 8 V to 12 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 of 12 V 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 12-V operation with minimal

increase in supply current.
