AD5260/AD5262 are digital potentiometers with 256-bit, 20 kΩ, 50 kΩ, 200 kΩ resistance values to choose from. They have low temperature coefficient and 4-wire SPI compatible serial data input. They are suitable as alternatives to mechanical potentiometers and can be used for applications such as gain and offset voltage adjustment in instrumentation, stereo channel volume control, programmable voltage-to-current conversion, etc.
The AD5260 and AD5262 are 1 or 2 channel, 256-bit, digitally controlled variable resistors (VR) that provide electronic adjustment similar to mechanical potentiometers. These devices feature a fixed resistor with a wiper tap controlled by a digital code loaded into a serial input register. The resistance between the wiper and either terminal (A or B) is fully programmable, while the total resistance (A to B) remains fixed at 20 kΩ, 50 kΩ, or 200 kΩ with a low temperature coefficient of 35 ppm/°C.
The device can operate with a single power supply up to 16.5 V or a dual supply of ±5.5 V.
The AD5260 and AD5262 models offer fixed resistances of 20 kΩ, 50 kΩ, or 200 kΩ.
All devices are guaranteed to operate within a temperature range of −40°C to +85°C.
