The INA1620 operates from ±2-V to ±18-V supplies, while maintaining excellent performance. However, some applications do not require equal positive and negative output voltage swing. With the INA1620, 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.

In all cases, the common-mode voltage must be maintained within the specified range. Key parameters are specified over the temperature range of T_A = –40°C to 125°C. Parameters that vary with operating voltage or temperature are shown in the Typical Characteristics section.
