Texas Instruments Current Sense Amplifier VSSOP 10-Pin

The Texas Instruments Current Sense Amplifier is a highly accurate current shunt and power monitor equipped with an I²C™ or SMBUS-compatible interface. Designed to monitor both a shunt voltage drop and bus supply voltage, this device features a programmable calibration value, conversion times, and averaging options. Combined with an internal multiplier, it enables direct readouts of current in amperes and power in watts.

This versatile amplifier senses current on common-mode bus voltages that can vary from 0 to 36V, entirely independent of the supply voltage. Operating from a single 2.7V to 5.5V supply, it draws a typical supply current of 330µA. Specified over an operating temperature range of -40°C to 125°C, it supports up to 16 programmable addresses on the I²C-compatible interface.

Key Features

• High-side or low-side sensing
• Reports current, voltage, and power
• High accuracy with 0.1% gain error (maximum) and 10µV offset (maximum)
• Configurable averaging options
• Green product with no Sb/Br

Handling Precautions

Please note that this device has limited built-in ESD protection. To prevent electrostatic damage to the MOS gates, the leads should be shorted together, or the device should be placed in conductive foam during storage or handling.

With product dimensions of 43 mm in height, 33 mm in width, and 15 mm in depth, and a lightweight design at just 0.05 grams, this surface-mount amplifier is suitable for compact and densely populated circuit boards.
