The AD9831ASTZ is an integrated circuit (IC) component designed by Analog Devices. It is a programmable waveform generator that can produce accurate sinusoidal, triangular, and square waveforms.
The AD9831ASTZ comes in a small surface mount package. It operates using a 2.3V to 5.5V power supply, making it suitable for a wide range of applications. The device has a built-in 10-bit digital-to-analog converter (DAC) that provides precise control over the output waveform.
Key features of the AD9831ASTZ include:
1. Frequency Generation: The AD9831ASTZ can generate frequencies from 0 Hz to 12.5 MHz. It has a frequency resolution of 0.087 Hz, allowing for accurate waveform generation.
2. Waveform Selection: The IC can produce three types of waveforms - sinusoidal, triangular, and square. The waveforms can be selected using control registers that can be programmed through a serial interface.
3. Phase Control: The AD9831ASTZ offers precise control over the phase of the output waveform. It includes a 28-bit phase accumulator that can be set to produce a phase shift in the output signal.
4. Serial Interface: The IC utilizes a 3-wire serial interface to communicate with an external microcontroller or digital system. This interface enables easy configuration and control of the waveform generator
