3 Description

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.
