GENERAL DESCRIPTION  
The AD7709 is a complete analog front end for low frequency  
measurement applications. It contains a 16-bit ⌺-⌬ ADC, selectable  
reference inputs, three switchable matched excitation current  
sources, low-side power switches, and a digital I/O port. The  
16-bit channel with PGA accepts fully differential, unipolar,  
and bipolar input signal ranges from 1.024 ϫ REFIN/128 to  
1.024 ϫ REFIN. It can be configured as two fully differential  
input channels or four pseudo-differential input channels. Signals  
can be converted directly from a transducer without the need for  
signal conditioning.  
13-Bit p-p Resolution @ 20 Hz, 20 mV Range  
16-Bit p-p Resolution @ 20 Hz, 2.56 V Range  
INTERFACE  
3-Wire Serial  
SPI®, QSPI™, MICROWIRE™, and DSP Compatible  
Schmitt Trigger on SCLK  
POWER  
Specified for Single 3 V and 5 V Operation  
Normal: 1.25 mA Typ @ 3 V  
The device operates from a 32.768 kHz crystal with an on-chip  
PLL generating the required internal operating frequency. The  
output data rate from the part is software programmable. The  
p-p resolution from the part varies with the programmed gain  
and output data rate.  
Power-Down: 7 ꢂA (32.768 kHz Crystal Running)  
ON-CHIP FUNCTIONS  
Rail-to-Rail Input Buffer and PGA  
Selectable Reference Inputs  
3 Switchable, Ratioed Current Sources for  
VBE Measurements  
4-Bit Digital I/O Port  
Low-Side Power Switches  
The part operates from a single 3 V or 5 V supply. When  
operating from 3 V supplies, the power dissipation for the part  
is 3.75 mW. The AD7709 is housed in a 24-lead TSSOP package.
