10 Power Supply Recommendations
The OPAx322-Q1 family is specified for operation from 1.8 V to 5.5 V (±0.9 V to ±2.75 V); 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 Typical Characteristics.
CAUTION
Supply voltages larger than 6 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, see Layout.
