9 Power Supply Recommendations
The OPAx348-Q1 family of devices 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. The Typical Characteristics presents parameters that can exhibit
significant variance with regard to operating voltage or temperature.
CAUTION
Supply voltages larger than 7 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 section.
