Texas Instruments INA148-Q1
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 commonmode rejection.| Part No. | INA148-Q1 |
