Product Description
Texas Instruments INA219AIDCNR is a precision digital current monitor IC designed for single-channel current sensing applications. It operates at supply voltages between 3V and 5.5V with a low supply current of 5mA, ensuring efficient and reliable performance in power-sensitive designs. The device includes a high common mode rejection ratio (CMRR) of 100dB, which enhances measurement accuracy by minimizing noise interference during current monitoring.
Housed in a compact 8-pin SOT-23 surface mount package measuring 3mm in length and 1.3mm in height, the INA219AIDCNR is suitable for space-constrained PCB layouts. Its industrial-grade operating temperature range from -40°C to 125°C allows for dependable operation in harsh environments often encountered in automotive, industrial, and embedded system applications.
This current sensing amplifier provides a digital output proportional to the voltage drop across a low-value resistor in the power rail. It enables real-time system protection, feedback control, and high-accuracy system monitoring in applications such as power management, instrumentation, and embedded electronics.
Key features include single-channel measurement capability, surface mount type, and digital output suitable for integration with microcontrollers and system controllers. This component meets general semiconductor standards but does not carry any specific automotive or industry approvals.
Texas Instruments' INA219 series Current Monitors are broadly used in electronic design, control systems, and industrial automation to optimize electrical performance and enhance system safety.
Operates on supply voltages from 3V to 5.5V for flexibility across system designs. High CMRR of 100dB ensures precise current sensing amid electrical noise. Compact 8-pin SOT-23 package allows for minimal PCB footprint in embedded systems.
Wide operating temperature range (-40°C to 125°C) enables industrial and automotive environment use. Surface mount device ideal for automated manufacturing and assembly. Low supply current of 5mA supports energy-efficient designs.
Provides digital output compatible with modern system controllers for monitoring and control. Applicable in electronic component manufacturing, power & connectors, instrumentation, and semiconductor amplifier systems.
