Product Overview: INA216A1RSWT from Texas Instruments

The INA216A1RSWT is a high-precision current-sense amplifier from Texas Instruments, designed to monitor both shunt voltage drops and bus voltages with an impressive accuracy. This device is part of TI's industry-leading portfolio of current-sense amplifiers that provide cost-effective solutions for power management and control in a wide range of applications.

Featuring a common-mode voltage range from -0.2V to +26V, the INA216A1RSWT is versatile and can operate on the high side, low side, or anywhere in between. This flexibility makes it suitable for a variety of systems, including those with a common ground. The amplifier's precision is further enhanced by its low offset voltage of 35 µV (max) and gain error of 0.2% (max), ensuring accurate current measurement over a wide temperature range (-40°C to +125°C).

The INA216A1RSWT has a fixed gain of 20 V/V, which simplifies the design process by eliminating the need for external gain-setting resistors. The device is also highly responsive with a bandwidth of 350 kHz, allowing it to handle fast current transients effectively. This makes it ideal for fast-switching applications like DC-DC converters, motor control, and overcurrent protection circuits.

For ease of integration into existing designs, the INA216A1RSWT comes in an ultra-small, leaded SOT-23 package that requires minimal board space. This makes it an excellent choice for space-constrained applications such as portable electronics, power management systems, and battery chargers.

Furthermore, the device features a quiescent current of only 260 µA, which is beneficial for power-sensitive applications. Its low power consumption, combined with the wide supply range of 2.7V to 5.5V, ensures that the INA216A1RSWT can be easily powered by the same supply as other ICs in the system, simplifying power management.

In summary, the INA216A1RSWT from Texas Instruments is a robust, accurate, and versatile current-sense amplifier that is ideal for a multitude of applications requiring precise current monitoring. Its compact size, low power consumption, and ease of use make it a valuable component for any power-sensitive and space-constrained design.
