FEATURES  
DESCRIPTION  
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.  
23  
Eight Input Channels  
Variable Power Management  
Independent Analog and Digital Supplies  
SPI™/ QSPI™/MICROWIRE/DSP Compatible  
Packaged in 16-Lead TSSOP  
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.  
The output serial data is straight binary and is  
compatible with several standards, such as SPI™,  
QSPI™, MICROWIRE, and many common DSP  
serial interfaces.  
KEY SPECIFICATIONS  
Conversion Rate: 200 ksps to 500 ksps  
DNL (VA = VD = 2.7V to 5.0V): ±0.4 LSB (max)  
INL (VA = VD = 2.7V to 5.0V): ±0.4 LSB (max)  
Power Consumption:  
The ADC108S052 may be operated with independent  
analog 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.  
3V Supply: 1.5 mW (typ)  
5V Supply: 7.5 mW (typ)  
APPLICATIONS  
Automotive Navigation  
Portable Systems  
The ADC108S052 is packaged in a 16-lead TSSOP  
package. Operation over the extended industrial  
temperature range of 40°C to +105°C is ensured.
