The document describes the features and characteristics of the AD5220 model product, including a 128-position digitally controlled variable resistor, low power consumption, mechanical potentiometer replacement, remote adjustment applications, etc.

Provides an overview of the AD5210 Series products, including features and specifications.

AD5207 is a 2-channel, 256-position digital potentiometer. It can be used to replace mechanical potentiometers, and is widely used in automotive electronics, audio volume adjustment, measurement instruments and other fields.

The AD5232 is an 8-bit dual nonvolatile memory digital potentiometer with 256-position resolution and full monotonic operation. It is suitable for applications such as mechanical potentiometer replacement, instrumentation gain and offset adjustment, programmable voltage-to-current conversion, programmable filters, delays, time constants, line impedance matching, and power supply adjustment.

The AD5204/AD5206 is a four-/six-channel digital potentiometer that provides 256 independently programmable channels with 10kΩ, 50kΩ and 100kΩ resistance values. It supports a 3-wire SPI-compatible serial data input and operates at a supply voltage of +2.7V to +5.5V single supply or -2.7V dual supply. It also has a power-on midscale preset function.

AD5204/AD5206 is a 4/6-channel digital potentiometer with 256-bit programmable positions, which can be used to replace mechanical potentiometers.

The AD5203 is a quad channel, 64-position digitally-controlled variable resistor (VR) device from Analog Devices. It can replace four traditional potentiometers and has power shutdown, 3-Wire SPI-Compatible Serial Data Input, 10MHz update data loading rate, +2.7V to +5.5V single supply operation, midscale preset and other features.

The AD5200 and AD5201 are programmable resistor devices that can be digitally controlled through a 3-wire SPI serial interface. These devices perform the same electronic adjustment function as mechanical potentiometers.

The 256-position, one-time programmable dual-channel I2C digital potentiometers AD5172/AD5173 provide a low-cost alternative for setting and fixing resistance. It allows unlimited adjustments prior to OTP activation and dynamic adjustments with user-defined presets through OTP overwrite. The potentiometers feature end-to-end resistance options of 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ, fast settling time, single supply voltage range of 2.7 V to 5.5 V, and other characteristics.

The DAC16 is a 16-bit high speed current-output digital-to- analog converter with a settling time of 500 ns. A unique com- bination of low distortion, high signal-to-noise ratio, and high speed make the DAC16 ideally suited to performing waveform synthesis and modulation in communications, instrumentation, and ATE systems. Input reference current is buffered, with full- scale output current of 5 mA. The 16-bit parallel digital input bus is TTL/CMOS compatible. Operating from +5 V and –15 V supplies, the DAC16 consumes 190 mW (typ) and is available in a 24-lead epoxy DIP, epoxy surface-mount small outline (SOL), and in die form.

AD5172/AD5173 is a 256-position one-time programmable dual-channel I2C digital potentiometer with various features and characteristics.

The AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer that uses fuse link technology to achieve memory retention of resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory setting in the digital potentiometer. This device performs the same electronic adjustment function like most mechanical trimmers and variable resistors.

The 256-position Two-Time Programmable I2C Digital Potentiometer AD5170 Rev. A is an integrated miniature potentiometer that uses I2C communications, features 256 positions, double-time programmable, set-and-forget, free adjustment, and low power consumption.
