Product Overview: INA283AIDGKT

The INA283AIDGKT from Texas Instruments is a precision, bidirectional current-sensing amplifier designed to monitor both shunt voltage drops and bus voltages in a wide array of applications. This high-accuracy device is housed in an 8-pin MSOP (DGK) package, which is ideal for space-constrained applications.

With an input common-mode voltage range that extends from -0.1V to +26V, and an operating voltage range of 2.7V to 5.5V, the INA283AIDGKT is versatile enough to handle various scenarios, including high-side and low-side current sensing. The device is optimized for direct current (DC) measurement, making it an excellent choice for power management systems that require precise current monitoring.

Key Features

• Precision Measurement: The INA283AIDGKT offers a gain error of only ±0.1%, which ensures accurate readings for critical applications.
• Wide Input Common-Mode Range: The device can measure voltages across shunts at common-mode voltages from -0.1V up to +26V, even beyond the supply voltage.
• Low Offset Voltage: A low offset voltage of ±100 µV maximizes measurement accuracy, especially important in low-side current sensing configurations.
• Adjustable Gain: The gain of the INA283AIDGKT can be adjusted with external resistors, allowing users to tailor the device to the specific needs of their application.
• High Bandwidth: With a bandwidth of up to 1 MHz, this amplifier is capable of capturing fast transient events.
