10 Power Supply Recommendations

The OPA2277 operational amplifier operates from ±2.5- to ±18-V supplies with excellent performance. Unlike most operational amplifiers which are specified at only one supply voltage, the OPA2277 is specified for real-world applications. A single set of specifications applies over the ±5- to ±15-V supply range. Specifications are ensured for applications between ±5- and ±15-V power supplies. Some applications do not require equal positive and negative output voltage swing. Power supply voltages do not need to be equal. The OPA2277 can operate with as little as 5 V between the supplies and with up to 36 V between the supplies. For example, the positive supply could be set to 25 V with the negative supply at –5 V, or vice-versa. In addition, key parameters are ensured over the specified temperature range, –55°C to 125°C. The Typical Characteristics show parameters which vary significantly with operating voltage or temperature.
