FEATURES

DESCRIPTION

•

CHIP-SCALE PACKAGE

The INA216 is a high-side voltage output current

shunt monitor that can sense drops across shunts at

common-mode voltages from +1.8V to +5.5V. Four

fixed gains are available: 25V/V, 50V/V, 100V/V, and

200V/V. The low offset of the Zerø-Drift architecture

enables current sensing with maximum drops across

the shunt as low as 10mV full-scale, or with wide

dynamic ranges of over 1000:1.

COMMON-MODE RANGE: +1.8V to +5.5V

OFFSET VOLTAGE: ±30mV

GAIN ERROR: ±0.2% MAX

CHOICE OF GAINS:

–

INA216A1: 25V/V

INA216A2: 50V/V

INA216A3: 100V/V

INA216A4: 200V/V

These devices operate from a single +1.8V to +5.5V

power supply, drawing a maximum of 25mA of supply

current. The INA216 series are specified over the

temperature range of –40°C to +125°C, and offered

in a chip-scale package.
