to an end-to-end open circuit condition on the A terminal and  
shorts the wiper to the B terminal, achieving a microwatt power  
shutdown state. When shutdown is returned to logic high, the  
previous latch settings put the wiper in the same resistance  
setting prior to shutdown as long as power to VDD is not re-  
moved. T he digital interface is still active in shutdown so that  
code changes can be made that will produce a new wiper posi-  
tion when the device is taken out of shutdown.

GENERAL D ESCRIP TIO N  
T he AD7376 provides a single channel, 128-position digitally-  
controlled variable resistor (VR) device. T his device performs the  
same electronic adjustment function as a potentiometer or vari-  
able resistor. T hese products were optimized for instrument and  
test equipment applications where a combination of high voltage  
with a choice between bandwidth or power dissipation are avail-  
able as a result of the wide selection of end-to-end terminal resis-  
tance values. T he AD7376 contains a fixed resistor with a wiper  
contact that taps the fixed resistor value at a point determined by  
a digital code loaded into the SPI-compatible serial-input regis-  
ter. T he resistance between the wiper and either endpoint of the  
fixed resistor varies linearly with respect to the digital code trans-  
ferred into the VR latch. T he variable resistor offers a completely  
programmable value of resistance between the A terminal and the  
wiper or the B terminal and the wiper. T he fixed A to B terminal  
resistance of 10 k, 50 k, 100 kor 1 Mhas a nominal tem-  
perature coefficient of –300 ppm/°C.  
T he AD7376 is available in both surface mount (SOL-16) and  
the 14-lead plastic DIP package. For ultracompact solutions  
selected models are available in the thin T SSOP package. All  
parts are guaranteed to operate over the extended industrial  
temperature range of –40°C to +85°C. For operation at lower  
supply voltages (+3 V to +5 V), see the AD8400/AD8402/  
AD8403 products.

T he VR has its own VR latch which holds its programmed resis-  
tance value. T he VR latch is updated from an internal serial-to-  
parallel shift register which is loaded from a standard 3-wire  
serial-input digital interface. Seven data bits make up the data  
word clocked into the serial data input register (SDI). Only the  
last seven bits of the data word loaded are transferred into the  
7-bit VR latch when the CS strobe is returned to logic high. A  
serial data output pin (SDO) at the opposite end of the serial  
register allows simple daisy-chaining in multiple VR applications  
without additional external decoding logic.

T he reset (RS) pin forces the wiper to the midscale position by  
loading 40H into the VR latch. T he SHDN pin forces the resistor  
T he last seven data bits clocked into the serial input register will  
be transferred to the VR 7-bit latch when CS returns to logic  
high. Extra data bits are ignored.
