Overview

The AD5204BN10 provides a 4-channel, 256-position digitally controlled variable resistor (VR) devices. This device performs the same electronic adjustment function as a potentiometer or variable resistor. Each channel of the AD5204BN10 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 endpoint 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 10 kΩ, 50 kΩ, or 100 kΩ has a nominal temperature coefficient of 700 ppm/°C.

The AD5204BN10 is available in the 24-lead surface-mount SOIC, TSSOP,PDIP packages and in a 32-lead, 5 mm × 5 mm LFCSP package. All parts are guaranteed to operate over the extended industrial temperature range of −40°C to +85°C. For additional single-, dual-, and quad-channel devices, see the AD8400/AD8402/AD8403 data sheets.
