Texas Instruments INA333AIDGKR Low-Power Zero-Drift Instrumentation Amplifier

Texas Instruments INA333AIDGKR Low-Power Zero-Drift Instrumentation Amplifier

INA333AIDGKR low-power, zero-drift instrumentation amplifier with 1 to 1000 V/V gain, 1.8 V to 5.5 V supply and rail-to-rail output.

The Texas Instruments INA333AIDGKR is a low-power instrumentation amplifier for small sensor signals. It uses a zero-drift design and supports a supply voltage from 1.8 V to 5.5 V. One external resistor sets the gain across a range of 1 to 1000 V/V.

Its rail-to-rail output helps make use of the available output range. RFI-filtered inputs help limit radio-frequency interference at the amplifier inputs. These features suit designs where low power and accurate signal measurement matter.

Use this precision sensor amplifier in pressure-sensing circuits, ECG equipment and portable instrumentation. Its wide gain range supports different signal levels, while its low-power design fits battery-powered measurement systems.
