The INA190A1IRSWR is a high-precision current sense amplifier brought to you by Texas Instruments. This device is specifically designed to accurately measure current across shunt resistors in a wide range of applications, from industrial systems to automotive electronics. The INA190A1IRSWR is notable for its precision performance and ease of use, making it an ideal choice for designers looking for reliable current monitoring solutions.
This current sense amplifier is part of the INA190 series, which are bidirectional, zero-drift, current shunt monitors that can sense drops across shunts at common-mode voltages from -0.2V to +26V, independent of the supply voltage. The INA190A1IRSWR variant offers a fixed gain of 20 V/V, which allows for a straightforward implementation without the need for external gain-setting components.
The device operates over a wide supply voltage range from 2.7V to 5.5V, with a quiescent current of only 260 µA, making it suitable for battery-powered applications. The INA190A1IRSWR also features a fast response time, which is critical for overcurrent protection and control in power management systems.
Its small footprint is made possible by the WSON-6 package, which is just 2mm x 2mm, saving precious board space in compact electronic designs. The device's high accuracy and low offset voltage (±35 µV) ensure precise current measurement, even at low current levels, which is essential for power-conscious designs.
The INA190A1IRSWR can be used in a variety of applications, including motor control, battery management, overcurrent protection, power management, and precision current measurement for system optimization. Its robust design is characterized by an operating temperature range of -40°C to +125°C, which ensures reliable performance in harsh environments.
In summary, the INA190A1IRSWR from Texas Instruments is a versatile and precise current sense amplifier that offers designers an efficient and accurate solution for current monitoring across a diverse range of applications.
