The AD9775BSVZ is a digital-to-analog (DAC) converter designed specifically to meet the requirements of professional audio applications. It is part of the latest generation of digital-to-analog converters from Analog Devices, offering high performance and value. The AD9775BSVZ has a single-ended, true-differential or multiple-input architecture, depending on the application. The device integrates a 16-bit DAC, a differential output buffer and a low-cost reference voltage buffer in a single IC. Its wide operating supply voltage range – 4.5V to 4.75V – makes it suitable for numerous applications.

The AD9775BSVZ is suited for audio and video applications in the broadcast, post production, and professional audio markets. The combination of features make it an ideal choice for use in professional audio systems. It is well suited for applications such as audio analog-to-digital (A/D) and digital-to-analog (DAC) conversions, line-level audio amplification, active speakers, and balanced-to-unbalanced configurations. With its low power consumption and low noise performance, the AD9775BSVZ is an excellent choice for professional audio designs.

The AD9775BSVZ is a low noise, high sample rate DAC providing up to 24bits of resolution. It offers excellent ac-coupling, low distortion and a wide dynamic range. The output of the AD9775BSVZ is floating, with a selectable output voltage range of either 1V or 2V p-p and a maximum output current of 2mA. The selectable voltage range makes it easy to use with various devices, such as digital-to-analog converters, analog-to-digital converters, and active speakers.

The AD9775BSVZ features a two-stage architecture for improved performance. The first stage is a 16-bit DAC with a static current output. This integrated DAC provides high linearity and low distortion performance. The second stage is a differential buffer with a low noise, low distortion output. The buffer provides the output voltage range and impedance matching. The effective impedance of the buffer is determined by the selected output range and is independent of the input signal level.

The AD9775BSVZ is designed for the audio frequency range, with a -3dB corner frequency of 20kHz. It is supplied in a small 16-pin SSOP package and has an operating temperature range of -40°C to +85°C. The device is very easy to use, with a simple three wire digital interface and no external components. Its small package size and minimal bill-of-materials allow cost-sensitive designs to be developed with limited board space, making it an excellent choice for professional audio applications.
