SNOSCX0A – JUNE 2013 – REVISED DECEMBER 2014 LMP92064 Precision Low-Side, 125-kSps Simultaneous Sampling,
Current Sensor and Voltage Monitor With SPI
1 Features 3 Description The LMP92064 is a precision low-side digital current
sensor and voltage monitor with a digital SPI
interface. This analog frontend (AFE) includes a
precision current sense amplifier to measure a load
current across a shunt resistor and a buffered voltage
channel to measure the voltage supply of the load.
The current and voltage channels are sampled
simultaneously by independent 125-kSps, 12-bit ADC
converters, allowing for very accurate power
calculations in unidirectional sensing applications. 1 Two Simultaneous Sampling 12-Bit ADCs
– Conversion Rate: 125 kSps (Minimum)
12-Bit Current Sense Channel
– Input-referred Offset: ±15 μV
– Common-mode Voltage Range: –0.2 V to 2 V
– Maximum Differential Input Voltage: 75 mV …
