SNAS298G –AUGUST 2005–REVISED JANUARY 2015  
ADC128S102 8-Channel, 500-ksps to 1-Msps, 12-Bit A/D Converter  
1 Features  
3 Description  
The ADC128S102 is a low-power, eight-channel  
CMOS 12-bit analog-to-digital converter specified for  
conversion throughput rates of 500 ksps to 1 MSPS.  
The converter is based on  
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.

The ADC128S102 may be operated with independent  
analog and digital supplies. The analog supply (VA)  
can range from +2.7 V to +5.25 V, and the digital  
supply (VD) can range from +2.7 V to VA. Normal  
power consumption using a +3-V or +5-V supply is  
2.3 mW and 10.7 mW, respectively. The power-down  
feature reduces the power consumption to 0.06 µW  
using a +3-V supply and 0.25 µW using a +5-V  
supply.
