INA148UA Description

Short technical summary and product information.

The INA148UA from Texas Instruments is a precision, low-power difference amplifier designed for high common-mode voltage applications. It features a fixed differential gain of 1V/V and a low quiescent current of 260μA.

This amplifier supports a wide supply range, operating on single supplies from 2.7V to 36V or dual supplies from ±1.35V to ±18V. Its high common-mode voltage capability extends to +75V at VS = +5V and ±200V at VS = ±15V. The device boasts low gain error of 0.075% maximum and low non-linearity of 0.002% maximum, with a high CMRR of 86dB.

The INA148UA is constructed with a monolithic precision bipolar op amp and a thin-film resistor network. The on-chip resistors are laser-trimmed for accurate gain and high common-mode rejection, with excellent temperature tracking maintaining accuracy over temperature.

Available in an 8-pin SOIC surface-mount package, the INA148UA is specified for an operating temperature range of -55°C to 125°C. It is also specified for the -40°C to +85°C industrial temperature range.
