Datasheet  
AS8510  
Data Acquisition Device for Battery Sensors  
ꢀ
Option for multiplexing either one differential  
input, or two single ended inputs or the internal temperature  
sensor on one channel  
1 General Description  
The AS8510 is a virtually offset free, low noise, two channel  
measurement device. It is tailored to accurately measure battery  
current from mA range up to kA range in conjunction with a 100 µΩ  
shunt resistor in series with the battery rail. Through the second  
measurement channel it enables capture of, either battery voltage  
synchronous with the current measurement, or, measure the analog  
output of an internal or external temperature sensor. Both channels  
are matched and can either measure small signals up to ±160 mV  
versus ground, through programmable gain amplifier or larger  
signals in the 0 to 1V range without the amplifier.  
ꢀ
Programmable current source for external temperature sensor  
connectable to any of the inputs  
ꢀ
ꢀ
ꢀ
High precision and high stability 1.2V reference voltage source  
Digital signal processing with filter options for both channels  
Four operating modes providing  
- Continuous data acquisition (or)  
- Periodic single-shot acquisition, (or)  
- Continuous acquisition on threshold crossing of programmed  
current levels (or)  
After analog to digital conversion and digital filtering, the resulting  
16-bit digital words are accessible through 4-wire standard serial  
interface.The device includes a number of additional features  
explained in the next section.  
- A combination of the above  
ꢀ
On chip high-precision 4MHz RC oscillator or option for external  
clock  
ꢀ
ꢀ
ꢀ
ꢀ
-40ºC to +125ºC ambient operation  
AEC - Q100 automotive qualified  
Internal chip ID for full traceability  
SSOP-20 pin package  
2 Key Features  
ꢀ
ꢀ
ꢀ
3.3V supply voltage  
Two High resolution 16 bit Σ−Δ A/D converters  
Programmable sampling to enable data throughputs from less  
than 1Hz to 8kHz  
3 Applications  
The AS8510 is ideal for shunt based batteries sensor. For high-side  
current sensing, the input signal may be conditioned using  
ꢀ
ꢀ
ꢀ
Zero Offset for both channels  
Independent control of data rate on both channels  
Precision, low noise, programmable gain amplifiers for both  
channels with gains 5, 25, 40, 100 to support wide dynamic  
ranges.
