The Texas Instruments INA191A3IYFDR is a single-channel current sense amplifier from the Zero-Drift series. It is designed to measure very small voltage drops across shunt resistors, enabling precise current monitoring. This device operates from a low supply voltage range of 1.7V to 5.5V, making it suitable for battery-powered applications.
Key electrical specifications include a very low input offset voltage of 2.5µV and an extremely low input bias current of 100 pA, which minimize measurement errors. The amplifier has a supply current of 43µA and a gain bandwidth product of 37 kHz. Its rail-to-rail output maximizes the dynamic range.
The INA191A3IYFDR is housed in a tiny 6-ball DSBGA package measuring 1.17 x 0.77 mm, ideal for high-density and space-constrained designs. It is designed for surface mounting and operates over an extended temperature range of -40°C to 125°C.
This current sense amplifier is suited for applications such as portable and battery-powered equipment, consumer electronics, medical instruments, and industrial control systems where accurate current monitoring is critical.
