Power Supply Recommendations

The TLV854x is specified for operation from 1.7 V to 3.6 V (±0.85 V to ±1.8 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 Typical Characteristics.

CAUTION

Supply voltages larger than 3.6 V can permanently damage the device.

For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines it is suggested that 100-nF capacitors be placed as close as possible to the op-amp 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.

Low bandwidth nanopower devices do not have good high frequency (> 1 kHz) AC PSRR rejection against high-frequency switching supplies and other 1-kHz and above noise sources, so extra supply filtering is recommended if kilohertz or above noise is expected on the power supply lines.
