FEATURES
DESCRIPTION
1-MHz Sample Rate Serial Devices
The
ADS79XX
is
a
12/10/8-bit
multichannel
analog-to-digital converter family. The following table
Product Family of 12/10/8-Bit Resolution
shows all twelve devices from this product family.
Zero Latency
The devices include a capacitor based SAR A/D
20-MHz Serial Interface
converter with inherent sample and hold.
Analog Supply Range: 2.7 to 5.25V
The devices accept a wide analog supply range from
I/O Supply Range: 1.7 to 5.25V
2.7V to 5.25V. Very low power consumption makes
Two SW Selectable Unipolar, Input Ranges: 0

devices
suitable
for
battery-powered
and
to 2.5V and 0 to 5V
isolated power supply applications.
Auto and Manual Modes for Channel Selection
A wide 1.7V to 5.25V I/O supply range facilitates a

CMOS digital hosts.
Two Programmable Alarm Levels per Channel
The serial interface is controlled by CS and SCLK for
Four Individually Configurable GPIOs for
easy connection with microprocessors and DSP.
TSSOP package devices. One GPIO for QFN
The input signal is sampled with the falling edge of

CS. It uses SCLK for conversion, serial data output,
Typical Power Dissipation: 14.5 mW (+VA = 5V,
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 mA)
Input Bandwidth (47 MHz at 3dB)
There are two software selectable input ranges (0V -
2.5V and 0V - 5V), four individually configurable
38-,30-Pin TSSOP and 32-,24-Pin QFN
GPIOs ( in case of TSSOP package devices), and
Packages
two programmable alarm thresholds per channel.
These features make the devices suitable for most

data acquisition applications.
PLC / IPC
The devices offer an attractive power-down feature.
Battery Powered Systems
This is extremely useful for power saving when the
Medical Instrumentation
device is operated at lower conversion speeds.
Digital Power Supplies
The 16/12-channel devices from this family are
Touch Screen Controllers
available in a 38-pin TSSOP and 32 pin QFN
