HMC925LC5 is a member of the well-known family of radio-frequency (RF) miscellaneous ICs and modules that provide the necessary components for a wide range of applications. Specifically, the HMC925LC5 is a low-power, low frequency, multi-input logic digital-to-analog converter (DAC) that uses a single-ended analog resistor network (CN) as its output. This makes the IC highly suitable for use in radio-frequency circuit designs, as well as general digital signal processing applications.

The HMC925LC5 measures in at only 7x7 mm, making it one of the smallest and most compact RF misc ICs and modules available. Additionally, the IC can be used in a wide range of temperature ranges, from -40°C to +85°C, allowing it to fit a variety of production processes and applications.

Working Principle:

At its core, the HMC925LC5 works on a single-ended signal path and utilizes a CN to convert digital control signals into analog outputs. This is done via an 8-bit programmable current digital-to-analog converter (DAC). The control signals are generated by a microcontroller, and each DAC is connected to 8-bit channels. All eight channels are then combined into a single 20-bit output.

The single-ended analog output of the IC consists of a string of resistors, with the value of each resistor determined by the DAC value. The different resistor values create alternate voltage drops when a voltage signal is applied, resulting in various analog signals being outputted. This is what allows the IC to be used for a number of different radio-frequency applications.

Application Field:

The HMC925LC5 is a highly versatile IC, and can be used in a wide variety of applications. In particular, due to its low power requirement, the chip is popularly used in radio-frequency circuit designs. It has been used in a variety of transmitter, receiver, and transceiver designs, as well as a number of digital signal processing applications.
