GENERAL DESCRIPTION  
V
DD  
The AD5260/AD5262 provide a single- or dual-channel, 256-  
position, digitally controlled variable resistor (VR) device.* These  
devices perform the same electronic adjustment function as a  
potentiometer or variable resistor. Each channel of the AD5260/  
AD5262 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 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 VR latch. 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 20 kW, 50 kW, or 200 kW has  
a nominal temperature coefficient of 35 ppm/C. Unlike the majority  
of the digital potentiometers in the market, these devices can operate  
up to 15 V or ±5 V provided proper supply voltages are furnished.

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, which is loaded from a standard 3-wire serial-input  
digital interface. The AD5260 contains an 8-bit serial register  
while the AD5262 contains a 9-bit serial register. Each bit is clocked  
into the register on the positive edge of the CLK. The AD5262  
address bit determines the corresponding VR latch to be loaded  
with the last 8 bits of the data word during the positive edging of  
CS strobe. A serial data output pin at the opposite end of the serial  
register enables simple daisy chaining in multiple VR applications  
without additional external decoding logic. An optional reset pin  
(PR) forces the wiper to the mid-scale position by loading 80H into  
the VR latch.

The AD5260/AD5262 are available in thin surface-mount TSSOP-14  
and TSSOP-16 packages. All parts are guaranteed to operate over  
the extended industrial temperature range of –40C to +85C.
