ADC108S052  
8-Channel, 200 kSPS to 500 kSPS, 10-Bit A/D Converter  
General Description  
Features  
n Eight input channels  
The ADC108S052 is a low-power, eight-channel CMOS 10-  
bit analog-to-digital converter specified for conversion  
throughput rates of 200 kSPS to 500 kSPS. The converter is  
based on a successive-approximation register architecture  
with an internal track-and-hold circuit. It can be configured to  
accept up to eight input signals at inputs IN0 through IN7.  
n Variable power management  
n Independent analog and digital supplies  
n SPI/QSPI/MICROWIRE/DSP compatible  
n Packaged in 16-lead TSSOP  
The output serial data is straight binary and is compatible  
Key Specifications  
with several standards, such as SPI , QSPI , MICROW-

The ADC108S052 may be operated with independent ana-  
log and digital supplies. The analog supply (VA) can range  
from +2.7V to +5.25V, and the digital supply (VD) can range  
from +2.7V to VA. Normal power consumption using a +3V or  
+5V supply is 1.5 mW and 7.5 mW, respectively. The power-  
down feature reduces the power consumption to 0.09 µW  
using a +3V supply and 0.30 µW using a +5V supply.

Applications  
The ADC108S052 is packaged in a 16-lead TSSOP pack-  
age. Operation over the extended industrial temperature  
range of −40˚C to +105˚C is guaranteed.
