Texas Instruments INA169NA/250 Current Sense Amplifier, SOT-23, 5-Pin

The INA169NA/250 from Texas Instruments is a high-side, unipolar current shunt monitor. It offers a wide input common-mode voltage range, high speed, and low quiescent current, all in a tiny SOT-23 package, making it suitable for a variety of applications.

With an input common-mode range from 2.7V to 60V and an independent supply voltage range of 2.7V to 60V, this device provides flexibility in measuring current across a shunt resistor. The low quiescent current of only 60µA minimises error, even when the supply is connected to either side of the shunt.

Key Features:

• Complete unipolar high-side current measurement circuit
• Wide supply and common-mode range
• Independent supply and input common-mode voltages
• Single resistor gain set
• Low quiescent current: 60µA (typical)
• Gain bandwidth product: 440kHz
• High CMRR: 120dB
• Input offset voltage: 1mV
• Input bias current: 10µA
• Single amplifier configuration

The device is housed in a surface-mount SOT-23 package with 5 pins, suitable for compact PCB designs. It operates over a temperature range of -40°C to +85°C, ensuring reliable performance in demanding environments. This current sense amplifier is ideal for precision current monitoring in a wide range of electronic applications.
