Description

DIGITAL POT 10KOHM 64 QUAD TSSOP-24

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 kΩ, or 100 kΩ has a ±1% channel-to- channel matching tolerance with a nominal temperature coeffi- cient of 700 ppm/°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. 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. For pin compatible higher resolution applications, see the 256- position AD8403 product.
