9 Power Supply Recommendations

The OPAx277 is specified for operation from 4 V to 36 V (±2 V to ±18 V); many specifications apply from –40°C to +85°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in the Typical Characteristics.

CAUTION

Supply voltages larger than 36 V can permanently damage the device; see the Absolute Maximum Ratings.

Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement, refer to the Layout Guidelines.
