1-MHz Sample Rate Serial Devices  
Product Family of 12/10/8-Bit Resolution  
Zero Latency  
The ADS79XX is  
analog-to-digital converter family. The following table  
shows all twelve devices from this product family.  
a
12/10/8-bit multichannel  
The devices include a capacitor based SAR A/D  
converter with inherent sample and hold.  
20-MHz Serial Interface  
Analog Supply Range: 2.7 to 5.25V  
I/O Supply Range: 1.7 to 5.25V  
The devices accept a wide analog supply range from  
2.7V to 5.25V. Very low power consumption makes  
these devices suitable for battery-powered and  
isolated power supply applications.  
Two SW Selectable Unipolar, Input Ranges: 0  
to 2.5V and 0 to 5V  
•
•
Auto and Manual Modes for Channel Selection  
A wide 1.7V to 5.25V I/O supply range facilitates a  
glue-less interface with the most commonly used  
CMOS digital hosts.  
12,8,4-Channel Devices can Share 16 Channel  
Device Footprint  
•
•
•
Two Programmable Alarm Levels per Channel  
Four Individually Configurable GPIOs  
The serial interface is controlled by CS and SCLK for  
easy connection with microprocessors and DSP.  
Typical Power Dissipation: 14.5 mW (+VA = 5V,  
+VBD = 3V) at 1 MSPS  
The input signal is sampled with the falling edge of  
CS. It uses SCLK for conversion, serial data output,  
and reading serial data in. The devices allow auto  
sequencing of preselected channels or manual  
selection of a channel for the next conversion cycle.  
•
•
•
Power-Down Current (1 µA)  
Input Bandwidth (47 at 3dB)  
30-Pin and 38-Pin TSSOP Packages  
There are two software selectable input ranges (0V -  
2.5V and 0V - 5V), four individually configurable  
GPIOs, and two programmable alarm thresholds per  
channel. These features make the devices suitable  
for most data acquisition applications.  
APPLICATIONS  
•

•
•
•
•
•
PLC / IPC  
Battery Powered Systems  
Medical Instrumentation  
Digital Power Supplies  
Touch Screen Controllers  
High-Speed Data Acquisition Systems  
High-Speed Closed-Loop Systems  
The devices offer an attractive power-down feature.  
This is extremely useful for power saving when the  
device is operated at lower conversion speeds.  
The 16/12-channel devices from this family are  
available in a 38-pin TSSOP package and the  
4/8-channel devices are available in a 30-pin TSSOP  
package.
