7.3.1 Operating Voltage

The OPAx323 series of operational amplifiers is fully specified from 1.8V to 5.5V and is designed for amplifier operation from 1.7V to 1.8V. In addition, many specifications apply from –40°C to 125°C. Parameters that vary significantly with operating voltages or temperature are provided in the Typical Characteristics section. TI highly recommends to add low-ESR ceramic bypass capacitors (CBYP) between each supply pin and ground. Only one CBYP is sufficient for single supply operation. Make sure that CBYP is placed as close to the device as possible and the power supply trace routes through CBYP before reaching the amplifier power supply terminals.
