ISL23315UFUZ

ISL23315UFUZ is an integrated digital potentiometer IC that provides a high level of system integration, flexibility and accuracy for analog signal path applications. It is designed to simplify the implementation of an adjustable gain stage or an adjustable gain path in a single system. This IC combines the elements of a voltage reference, a digital-to-analog converter (DAC), an integrated potentiometer, a temperature sensor, an analog summing node, a configuration cell, and an I²C-compatible serial interface. It is ideal for applications requiring calibration, system diagnostic, and user adjustments of the signal path for process control and system scalability.

The ISL23315UFUZ is an Analog Devices Inc. POT-type IC that offers a single-channel, 16-bit resolution adjustable potentiometer in a small, lead-free package. It is designed to replace mechanical trimming potentiometers in a wide range of analog systems, including AC adapters and voltage regulators, DC-DC converters, power supplies, audio and instrument amplifiers, photovoltaic systems, automotive navigation systems, device controllers, and medical and industrial equipment.

The ISL23315UFUZ consists of a voltage reference, a DAC, an integrated digital potentiometer, a temperature sensor, an analog summing node, a configuration cell, and an I²C-compatible serial interface. It is designed to provide optimal design flexibility and cost-effectiveness for applications that require potentiometer adjustment. The digital potentiometer enables adjustment of analog signal paths from the I²C-compatible interface or from a customer-defined user interface (GUI) or a hardware control device.

With its high-precision and wide-range adjustable gain, the ISL23315UFUZ is ideal for various analog control applications. It also features extremely low electrical noise, low power consumption, and very low-temperature drift, making it well suited for industrial, medical, and consumer applications. The wide temperature range of operation (from -40°C to +85°C) makes the ISL23315UFUZ suitable for use in a wide range of operating environments.

The ISL23315UFUZ is available in TQFP and U-LCC packages and is designed to provide superior performance and reliability in a wide range of harsh, high-temperature environments. When used in combination with the ISL22335 USB-I²C bridge, the ISL23315UFUZ can enable configuration and operation of the device from a PC or a host system.
