GENERAL DESCRIPTION
The AD5263 is the industry first quad channel, 256 position,
digital potentiometer
1
selectable digital interface. These devices
perform the same electronic adjustment function as mechanical
potentiometers or variable resistor with enhanced resolution, solid-
state reliability, and superior low temperature coefficient
performance. Each Channel of the AD5263 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 3 wire SPI or 2-wire
I
2
C compatible serial-input register. The resistance between the
wiper and either end point of the fixed resistor varies linearly with
respect to the digital code transferred into the RDAC latch
1
. The
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 20k, 50k or
200k
has a nominal temperature coefficient of 50 ppm/°C. Unlike
majority of the digital potentiometers in the market, these devices
can operate up to 15V or ±5V provided proper supply voltages are
furnished.
The AD5263 are available in thin narrow body TSSOP-24. All
parts are guaranteed to operate over the extended automotive
temperature range of -40°C to +125°C.
