Product Overview: INA284AIDGKR by Texas Instruments

The INA284AIDGKR is a precision, low-power, current-sense amplifier from Texas Instruments, designed to monitor current in precision applications. This device is part of the INA28x family and is packaged in an 8-pin MSOP (DGK) package, providing a compact solution for current sensing in space-constrained applications.

The INA284 offers a wide input common-mode range from -14V to +80V, making it suitable for both high-side and low-side current sensing in systems operating at these voltages. This versatility allows the INA284AIDGKR to be used in a variety of applications, including motor control, battery management, overcurrent protection, and power management in automotive and industrial systems.

One of the key features of the INA284AIDGKR is its zero-drift architecture, which ensures high accuracy over time and temperature by minimizing offset and gain errors. This results in a low offset voltage of 35 µV (max) and a gain error of 0.1% (max), making it ideal for precision measurements.

The device offers a quiescent current of only 900 µA, which is beneficial for power-sensitive applications. Additionally, it supports a wide supply voltage range from 2.7V to 5.5V, allowing for flexibility in system design. The INA284AIDGKR provides a gain bandwidth product of 500 kHz, which enables fast response times for transient events.

The output of the INA284AIDGKR is a voltage proportional to the measured current, which can be easily interfaced with analog-to-digital converters (ADCs) or microcontrollers for digital processing. The amplifier's gain is set by an external resistor, giving designers the flexibility to set the desired gain based on their specific application requirements.

Overall, the INA284AIDGKR from Texas Instruments is a reliable and precise solution for current sensing in a wide range of applications. Its high accuracy, low power consumption, and compact form factor make it an excellent choice for designers looking to optimize their system performance.
