SGM8194 Bidirectional, Low Power, Zero-Drift, Precision Current-Sense Amplifier
●The SGM8194 series is a low power, high DC and AC CMRR, voltage output current-sense amplifier. This device is designed to provide optimal performance in battery management systems requiring over-current protection and precision current measurement. The SGM8194 can sense voltage drops across current-sense resistor with common mode voltage from -0.1V to 40V. The common mode voltage is independent with the power supply voltage due to its AC coupling and related signal sampling structure.
●The SGM8194 features low input bias current, low offset voltage and zero-drift. The dynamic range is extended due to the latter two features when measuring current. Larger current-sense resistor can be used in mA level measurement application and it provides accurate current measurements. Small current-sense resistor is always used to reduce power loss in power efficiency sensitive systems. The SGM8194 can provide accurate current measurements in system where small current-sense resistor is used.
●The SGM8194 series provides two fixed gains: 100V/V and 200V/V. It operates with a single power supply from 2.1V to 5.5V. When this device is enabled, it draws a 60μA typical power supply current, and it consumes only 10nA when disabled.
●The SGM8194 is available in Green UTQFN-1.8×1.4-10L and SC70-6 packages. It is rated over the -40°C to +125°C temperature range.
