10 Power Supply Recommendations

The ALM2402Q1 device is recommended for continuous operation from 4.5 V to 16 V (±2.25 V to ±8.0 V) for Vcc and 3.0 V to 16V (±1.5 V to ±8.0 V) for Vcc_o(x); 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 18 V can permanently damage the device (see 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.
