AD5280BRUZ50

AD5280 is a single-channel 256-position, I²C-compatible digital potentiometer. It performs 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. It has sleep mode programmability which allows any level of preset in power-up and is an alternative to a costly EEPROM solution. This potentiometer is widely used in application such as multimedia, video, and audio, communications, mechanical potentiometer replacement, instrumentation: gain, offset adjustment, programmable voltage source, programmable current source, line impedance matching.

• Operating supply voltage is +10V to +15V

• Packaging style is 14-lead TSSOP
• Low temperature coefficient is 30ppm/°C typ (rheostat mode, VAB = VDD, wiper = no connect)
• Power-on midscale preset1
• Programmable reset
• Logic supply current is 60μA at (VLOGIC = 5V)
• Bandwidth (3dB) is 150kHz at (RAB = 50kΩ, code = 0x80)
