Описание
AD5241 is a single channel, 256-position, digitally controlled variable resistor (VR) device. This device performs the same electronic adjustment function as a potentiometer, trimmer or variable resistor. Each VR offers a completely programmable value of resistance between the A terminal and the wiper, or the B terminal and the wiper. The nominal temperature coefficient is 30ppm/°C. Wiper position programming defaults to midscale at system power on. When powered, the VR wiper position is programmed by an I2C-compatible, 2-wire serial data interface. It has two extra programmable logic outputs available that enable users to drive digital loads, logic gates, LED drivers, and analog switches in their system. Applications include multimedia, video and audio, communications, mechanical potentiometer replacement, instrumentation: gain, offset adjustment, programmable voltage-to-current conversion, and line impedance matching.
• Internal power on midscale preset
• Single-supply 2.7V to 5.5V or dual-supply ±2.7V for AC or bipolar operation
• I2C-compatible interface with readback capability
• Extra programmable logic outputs
• Self contained shutdown feature
• A-to-B terminal resistance of 1Mohm
• Differential nonlinearity of ±0.4LSB (VDD = 2.7to 5.5V, VA = VDD, VB = 0V, -40°C < TA < +105°C)
• 6KHz -3dB bandwidth (RAB = 1Mohm), code = 0x80
• Wiper resistance of 60 ohm (IW = VDD/R)
• 14-lead SOIC package, -40°C to +105°C temperature range
