8.3 Power Supply Recommendations

The nominal performance of the PGA849 is specified with input-stage supply and output-stage supply voltages of ±15V, and VICM and VREF at mid-supply. Within the specified limits, custom input common-mode and output reference voltages can be used without compromising performance; see also Section 6.3. To prevent damage to internal circuitry, the output-stage power supplies are clamped to stay within the input-stage supply voltage levels; see also Section 7.2.

CAUTION: Supply voltages higher than 40V (±20V) can permanently damage the device. Parameters that vary over supply voltage or temperature are shown in Section 6.6 of this data sheet.
