AD5112BCPZ10-RL7 is a digital potentiometer integrated circuit (IC) device manufactured by Analog Devices Incorporated. It is part of the company\'s Data Acquisition - Digital Potentiometers product group. The device is a quad-channel digital potentiometer with each channel having a 256-position resolution. The device typically uses a single 2.7 V to 5.5 V supply input, operated over the temperature range of 0°C to +70°C.

AD5112BCPZ10-RL7 is a non-volatile memory that is used to adjust the voltage level using four separate, active channels. These channels can be programmed independently, allowing developers to efficiently develop systems with multiple voltage levels in a single package. The device is an ideal choice for applications requiring multiple potentiometer-type adjustable voltage control, such as gains and offsets in video and audio systems, filtering and equalization in communications systems, amplification in measurement instruments, and loop compensation in switched-mode power supplies.

The principle of operation of AD5112BCPZ10-RL7 is that the Adjustment Terminal Voltage (V ADJ ) will be set by connecting a digital code, or word, to a digital-to-analog converter, through the logic-controlled digital port. This code is stored in internal non-volatile memory, meaning that the voltage level is retained even in the absence of power.

The IC contains a wiper terminal that can be used to ground or leave floating depending on the application. When the wiper is grounded, the device being controlled is adjusted across the full range of 0V to V ADJ range. When the wiper is left floating, the device being controlled will be adjusted in the range of V ADJ to V ADJ .

When connected in a circuit, the device can be used to set and maintain output levels during power up, power down, or when input signals are changed. It can also be used to create pre-set switching points or thresholds for a variety of functions. All four channels can be individually programmed and are also synchronized externally and from channel to channel.

The AD5112BCPZ10-RL7 device offers features such as write ensure to ensure reliable non-volatile write operations, high non-volatility, and digital trimming and protection. It is designed to achieve high accuracy over the full operating temperature range – typically 0.1% over -40°C to +85°C. In addition, the device is built with ESD protection and has an internal linear regulator which eliminates the need for a separate voltage regulator.

In summary, the AD5112BCPZ10-RL7 is a digital potentiometer IC device designed to provide accurate voltage control in a wide range of applications. The device is suitable for use in applications requiring multiple voltage levels, such as video and audio systems, communications systems, and power supply loop compensation. The device is highly accurate over temperature and offers write ensure and high non-volatility features. It also features ESD protection and an integrated linear voltage regulator.
