7.3 Power Supply Recommendations

The OPAx197-Q1 are specified for operation from 4.5V to 36V (±2.25V to ±18V); many specifications apply from –40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in Section 5.9.

CAUTION:

Supply voltages larger than 40V can permanently damage the device; see Absolute Maximum Ratings.

Place 0.1μF 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, see Section 7.4.
