Product Overview
The INA169 is a Texas Instruments high-side current shunt monitor categorized under Signal_Chain. It operates across a recommended 2.7 V to 60 V supply range and supports a 2.7 V to 60 V common-mode input range, matching its electrical-characteristics operating range. The device converts shunt-sense voltage into output current with 1000 µA/V typical transconductance over VSENSE = 10 mV to 150 mV.
Electrical limits include 100 mV to 500 mV full-scale sense voltage, ±0.01% typical nonlinearity error, and ±0.5% typical total output error at VSENSE = 100 mV. Dynamic parameters include 440 kHz typical bandwidth with ROUT = 10 kΩ and 220 kHz typical bandwidth with ROUT = 20 kΩ, with 2.5 µs and 5 µs typical settling times under the stated load conditions.
The package is a 5-pin SOT-23 (DBV) with a 2.90 mm x 1.60 mm body. Thermal data for the DBV package includes 168.3°C/W junction-to-ambient resistance, 73.8°C/W junction-to-case-top resistance, and 28.1°C/W junction-to-board resistance. The typical application transfer function is VO = IS × RS × RL / 1 kΩ.
