Analog Devices Inc. AD5203ARUZ10-REEL

Description
The AD5203 is a quad-channel, 64-position digitally-controlled variable resistor (VR) device. It performs the same electronic adjustment function as a potentiometer or variable resistor. Each part contains four independent variable resistors in a 24-lead SOIC and TSSOP-24 packages.
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.
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.
