The INA148-Q1 is a precision, low-power, unity-gain difference amplifier with a high common-mode input voltage range. The device consists of a monolithic, precision, bipolar operational amplifier with a thin-film resistor network.
The on-chip resistors are laser trimmed for an accurate 1-V/V differential gain and high common-mode rejection. Excellent temperature tracking of the resistor network maintains high gain accuracy and common-mode rejection over temperature. The INA148-Q1 operates on single or dual supplies. These features make the INA148-Q1 suitable for HEV/EV and Powertrain applications, specifically in battery management systems.
The INA148-Q1 is available in an 8-pin SOIC, surface-mount package, and is specified for operation over the temperature range of –40°C to 125°C.
