AD5162BRMZ10

The AD5162BRMZ10 is a low-power, non-volatile digital potentiometer from Analog Devices, Inc. It offers an adjustable resistor network where an individual tap is selected via an I2C serial interface. This enables the circuit control necessary for many data acquisition applications. The AD5162BRMZ10 also offers low power consumption, a wide operating temperature range, and works with a single 1.8 V to 5.5 V supply voltage.

Application Field

The AD5162BRMZ10 is suitable for a wide range of data acquisition applications, including industrial process and instrumentation systems, automotive systems, process control, system monitoring and even consumer electronics devices. It is often used to control the gain and set limits on signals, as well as to provide adjustable resistance for electronically adjustable mechanical devices such as potentiometers.

The AD5162BRMZ10 is particularly well suited for applications where minimal board area is a determining factor. It is also suitable for applications requiring a non-volatile element, since memory states are retained when power is removed.

Working Principle

The AD5162BRMZ10 is a non-volatile, digitally-controlled resistor network, consisting of two separately adjustable resistor strings. Each string has 24 resister elements. When a voltage is applied to the wiper of a string, a tap is selected, and the resistance between the tapped wiper and the wiper at the opposite side of the string is equal to the resistor element value. The position of each wiper is adjusted by an I2C digital interface.

The AD5162BRMZ10 has two separate registers, one for each string. The two registers are mapped as one 32-bit register, with the first eight bits controlling the first string, and the last eight bits controlling the second string. Each register can be set to any value between 0 and 24.

The AD5162BRMZ10 is also available in a serial-to-parallel configuration. This configuration allows a single serial I2C port to be used to control the wiper position of both strings. This configuration is called the "single-shot" mode.

The AD5162BRMZ10 is available in several packages, including a TSSOP-16 and an SOIC-16. The TSSOP-16 version is the recommended package for applications requiring minimal board area.
