Product Overview: INA216A3RSWT by Texas Instruments

The INA216A3RSWT is a high-precision, bidirectional, current-sense amplifier from Texas Instruments, designed to offer industry-leading performance for power management and control applications. This device is part of TI's extensive portfolio of current-sense amplifiers that provide high accuracy, low power consumption, and ease of use.

Key Features

• High Accuracy: The INA216A3RSWT offers a low offset voltage and high common-mode rejection ratio (CMRR), which ensures accurate current measurement even in the presence of noise and voltage fluctuations.
• Wide Common-Mode Range: It can measure currents across shunts at common-mode voltages from -0.2V to +26V, independent of the supply voltage. This feature makes it suitable for both high-side and low-side current sensing.
• Low Power Consumption: With a quiescent current of only 100µA, this amplifier is an excellent choice for battery-powered and energy-efficient systems.
• Adjustable Gain: The INA216A3RSWT has an internally fixed gain of 200V/V, providing a precise amplification of the differential voltage across a current-sense resistor.
• Wide Supply Range: The device operates over a supply range of 1.8V to 5.5V, allowing for flexibility in various circuit designs and compatibility with low-voltage systems.
• Small Footprint: Housed in a tiny UQFN package, the INA216A3RSWT occupies minimal board space, making it ideal for space-constrained applications.
