8.1.1 Operating Voltage

OPA211 series operational amplifiers operate from ±2.25- to ±18-V supplies while maintaining excellent performance. The OPA211 series can operate with as little as 4.5 V between the supplies and with up to 36 V between the supplies. However, some applications do not require equal positive and negative output voltage swing. With the OPA211 series, power-supply voltages do not need to be equal. For example, the positive supply could be set to 25 V with the negative supply at –5 V or vice-versa.

The common-mode voltage must be maintained within the specified range. In addition, key parameters are assured over the specified temperature range, TA = –40°C to +125°C. Parameters that vary significantly with operating voltage or temperature are shown in the Typical Characteristics.
