The AD5203 provides a quad channel, 64-position digitally-  
controlled variable resistor (VR) device. These parts perform the  
same electronic adjustment function as a potentiometer or vari-  
able resistor. The AD5203 contains four independent variable  
resistors in a 24-lead SOIC and the compact TSSOP-24 pack-  
ages. Each part contains a fixed resistor with a wiper contact  
that taps the fixed resistor value at a point determined by a digi-  
tal code loaded into the controlling serial input register. The  
resistance between the wiper and either endpoint of the fixed  
resistor varies linearly with respect to the digital code transferred  
into the VR latch. Each variable resistor offers a completely  
programmable value of resistance, between the A terminal and  
the wiper or the B terminal and the wiper. The fixed A-to-B  
terminal resistance of 10 k, or 100 khas a ±1% channel-to-  
channel matching tolerance with a nominal temperature coeffi-  
cient of 700 ppm/°C.

The reset RS pin forces the wiper to the midscale position by  
loading 20H into the VR latch. The SHDN pin forces the resis-  
tor to an end-to-end open circuit condition on terminal A and  
shorts the wiper to terminal B, achieving a microwatt power  
shutdown state. When shutdown is returned to logic-high the  
previous latch settings put the wiper in the same resistance set-  
ting prior to shutdown.  
The AD5203 is available in a narrow body P-DIP-24, the  
24-lead surface mount package, and the compact 1.1 mm thin  
TSSOP-24 package. All parts are guaranteed to operate over the  
extended industrial temperature range of –40°C to +85°C.  
Each VR has its own VR latch which holds its programmed  
resistance value. These VR latches are updated from an internal  
serial-to-parallel shift register that is loaded from a standard  
3-wire serial-input digital interface. Eight data bits make up the  
data word clocked into the serial input register. The data word is  
decoded where the first two bits determine the address of the VR  
latch to be loaded, the last 6-bits are data. A serial data output  
pin at the opposite end of the serial register allows simple daisy-  
chaining in multiple VR applications without additional external  
decoding logic.  
For pin compatible higher resolution applications, see the 256-  
position AD8403 product.
