SNOSCX0 JUNE 2013  
Precision Low-Side, 125 kSps Simultaneous Sampling,  
Current Sensor and Voltage Monitor with SPI  
Check for Samples: LMP92064  
1
FEATURES  
DESCRIPTION  
The LMP92064 is a precision low-side digital current  
Two Simultaneous Sampling 12-bit ADCs  
Conversion Rate: 125 kSps (Min)  
12-bit Current Sense Channel  
sensor and voltage monitor with digital SPI  
a
interface. This analog front-end (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.  
Input-referred Offset: ±15 μV  
Common-mode Voltage Range: –0.2V to 2V  
Maximum Differential Input Voltage: +75 mV  
Fixed Gain: 25 V/V  
Gain Error: ±0.75 % (Max)  
Bandwidth (–3dB): 70 kHz  
DC PSRR: 100 dB  
The LMP92064 includes an internal 2.048V reference  
for the ADCs, eliminating the need of an external  
reference and reducing component count and board  
space.  
DC CMRR: 110 dB  
12-bit Voltage Channel  
A host can communicate with the LMP92064 using a  
four-wire SPI interface running at speeds of up to 20  
MHz. The fast SPI interface allows the user to take  
advantage of the higher bandwidth ADC to capture  
fast varying signals. The four-wire interface with  
dedicated unidirectional input and output lines also  
allows for an easy interface to digital isolators in  
applications where isolation is required.  
INL: ±1LSB  
Offset Error: ±2 mV (Max)  
Gain Error: ±0.75% (Max)  
Maximum Input Voltage: +2.048V  
Bandwidth: 100 kHz  
Internal Reference  
The LMP92064 operates from a single 4.5V to 5.5V  
supply and includes a separate digital supply pin. The  
LMP92064 is specified over a temperature range of  
–40°C to 105°C, and is available in a 5mm x 4mm  
WSON-16 package.  
SPI Frequency: Up to 20 MHz
