INA169NA Description

Short technical summary and product information.

The Texas Instruments INA169NA is a versatile high-side, unipolar current shunt monitor. It operates with a wide input common-mode voltage range from 2.7V to 60V, allowing for flexible power supply configurations. The device features a low quiescent current of 60 µA typical, minimizing power consumption and error when the power supply is connected to either side of the current measurement shunt.

 

Key electrical specifications include a bandwidth of 220 kHz, a maximum input offset voltage of 1000 µV, and a typical input offset voltage drift of 1 µV/°C. The gain is adjustable via an external resistor, allowing for gains from 1 to over 100. The common-mode rejection ratio is a minimum of 100 dB.

 

Packaged in a compact 5-pin SOT-23 (DBV) package with dimensions of 8.12 mm², the INA169NA is suitable for space-constrained applications. It operates within an environmental temperature range of -40°C to 125°C. The device converts a differential input voltage to a current output, which is then converted back to a voltage with an external load resistor, enabling creative current measurement solutions.
