RS199

Bidirectional, Zero-Drift, High or Low Side,

Voltage Output, Current Shunt Monitor

1 FEATURES

3 DESCRIPTIONS

The RS199 series of voltage-output, current-shunt

monitors (also called current-sense amplifiers) are

commonly used for overcurrent protection, precision

current measurement for system optimization, or in

closed-loop feedback circuits. This series of devices

can sense drops across shunt resistors at common

mode voltages from 0 V to 26 V, independent of the

supply voltage. Three fixed gains are available: 50

V/V, 100 V/V, and 200 V/V. The low offset of the zero-

drift architecture enables current sensing with

maximum drops across the shunt as low as 10mV full-

scale.

Wide Common-Mode Range: 0V to 26 V

Input Offset Voltage: ±1 00μV (TYP)

Accuracy: (TYP)

– Gain Error:

– ±0.4% (A Version)

– ±2μV/°C Offset Drift

– 10ppm/°C Gain Drift

•

Choice of Gains:

– RS199A: 50 V/V

– RS199B: 100 V/V

– RS199C: 200 V/V

•

Quiescent Current: 72μA (TYP)

Supply Range: +2.7V to +26V

Operating Temperature Range: -40°C to

+125°C

These devices operate from a single 2.7V to 26V

power supply, drawing 72μA of supply current. The

RS199 families of operational amplifiers are specified

at the full temperature range of -40°C to 125°C, and

offered in SOT363(SC70-6) packages.
