Working Principle

The CS5351-DZZ is an 8-bit DAC, meaning it can convert a binary number into an analog voltage or current. The CS5351-DZZ uses the Binary-Weighted Architecture, where each bit of the digital code is weighted according to its position. The MSB (most significant bit) is given 2^7 weight, the second bit 2^6 weight and so on. The weights are summed to form the analog output voltage.

The CS5351-DZZ can accept digital input codes of up to 8-bits, giving it the ability to generate analog outputs of up to 8-bits with no additional noise, distortion or error. The device has a maximum output of ±5V with a differential gain and offset error of 0.05%. It has a data transfer rate of up to 25MS/s and is capable of outputting frequencies up to 1MHz. The CS5351-DZZ has an internal Band-Gap Voltage Reference that maintains a consistent output voltage in spite of variations in ambient temperature.

The CS5351-DZZ is designed to be operated from a single 3.3V or 5V supply. It draws a maximum supply current of 600μA (typical) and can operate in temperatures ranging from -40°C to +85°C. It is available in a 14-pin DIP or SOIC package and is designed to be used with a variety of peripherals, such as FPGAs, ASICs and CPLDs. The device also features a shut-down pin for disabling the output drivers.

Conclusion

The CS5351-DZZ Digital-to-Analog Converter is a powerful and versatile device, offering high precision and low power consumption. It has a wide range of applications in data acquisition, signal processing and industrial control. Its Binary-Weighted Architecture and Band-Gap Voltage Reference make it well-suited to a variety of applications, including high-end audio systems, dynamic range compressors and ADC testing. It is available in both DIP and SOIC packages and is easily integrated into existing designs.
