EVAL-AD5451EBZ

Introduction

The ADI Evaluation Board EVAL-AD5451EBZ is a Digital to Analog Converter (DAC) that lets users evaluate the performance of the AD5451 Quad-Channel 12-Bit Current-Output Digital-to-Analog Converter. In this article, we will discuss the application field and working principle of the Evaluation Board EVAL-AD5451EBZ.

Application Fields of EVAL-AD5451EBZ

The EVAL-AD5451EBZ is designed to connect to a computer system for data evaluation purpose. It provides a cost-effective solution for application fields such as medical, industrial, aerospace, and defense, as well as other circumstances that require data conversion. The board’s main applications are either to generate a single register in a Delta Sigma Modulator (DSM) or as a bridge to connect analog and digital systems.

The board can be used to provide high-resolution signals to generate analog waveforms for motor control, piezoelectric sensors, strain gages, and other hard-to-measure processes. It is also well suited for driving a laser diode or driving a timer/light controller. The board could also be used as a Digital Light Source, a Real Time Signal Source, a Pulse Width Modulation (PWM) Generator, and more.

Working Principle of EVAL-AD5451EBZ

The board operates as an 8-bit range of signals with a 4-bit control setting. It has four serial input data pins, one voltage reference that is adjustable, and one current-output voltage range. It also has a maximum output of ±15mV per bit of resolution. The logic high level runs from 0.4V to +5V and the logic low level runs from 0V to +2V.

The EVAL-AD5451EBZ is based on the AD5451 Quad-Channel 12-Bit Current-Output Digital-to-Analog Converter, which can be programmed and updated via an SPI module. That sends update registers on the fly to the board and it processes them accordingly. Once the SPI module receives the digital data stream, it is converted into a continuous analog output signal. The analog output is achieved by multiplying the input data by the reference voltage.

The board is also equipped with a voltage monitor terminal which can be used to monitor the output voltage levels and ensure that they are within the specified parameters. It also includes a debug port which can be used to monitor and control the function of the board.

Conclusion

The Evaluation Board EVAL-AD5451EBZ is a highly versatile device which is suitable for a wide range of application fields. It is based on the AD5451 Quad-Channel 12-Bit Current-Output Digital-to-Analog Converter and provides a cost-effective solution for data conversion needs. It operates on an 8-bit range of signals with a 4-bit control setting and is equipped with a voltage monitor terminal and a debug port.
