9 Power Supply Recommendations

The LMV84x-Q1 is specified for operation from 2.7 V to 12 V (±1.35 V to ±6 V) over a –40°C to 125°C temperature range. Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in the Absolute Maximum Ratings.

CAUTION

Supply voltages larger than 13.2 V can permanently damage the device.

For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines, TI suggests placing 10-nF capacitors as close as possible to the operational amplifier power supply pins. For single supply, place a capacitor between V+ and V– supply leads. For dual supplies, place one capacitor between V+ and ground, and one capacitor between V– and ground.
