Data Acquisition - Digital to Analog Converters (DAC) enable conversions from digital data to physical signals. The AD5697RBCPZ-RL7 is an 8-bit precision DAC from Analog Devices that is particularly suited for use in applications where low power consumption and versatile digital input formats are desirable. In this article, we’ll take a look at the application fields and working principle of the AD5697RBCPZ-RL7.

Overview

The AD5697RBCPZ-RL7 is a low-power, 8-bit voltage-output DAC with a C-LTE amplifier. It has a low-noise, high-linearity design, allowing it to achieve accurate analog output voltage over a wide temperature range. The device features several features, such as an internal reference, a 2.5V reference, an output buffer, and a power-down mode. Its output voltage range is 0V to 2.5V. It is a small, 8-pin QFN package, making it suitable for space-constrained applications.

Application Fields

The AD5697RBCPZ-RL7 is suitable for a wide range of applications. First, it is well-suited for use in digital-to-analog conversion for audio applications. Its low-noise design makes it suitable for use in low-noise audio systems. It can also be used to provide such as volume, tone, balance, and simulated acoustic feedback in car audio systems. Secondly, the DAC is suitable for to provide adjustable analog signals in industrial and medical monitoring applications. It can be used to control operating signals in programmable logic controllers (PLCs), process control systems, and medical and laboratory instruments. Finally, it is suited for powering displays and other digital devices with analog voltage signals.

Digital Input Format

The AD5697RBCPZ-RL7 supports several digital input formats and options. It is compatible with Serial Peripheral Interface (SPI) as well as I2C, I2C+, and I2S. The device is also compatible with Digital to Analog Audio Interface (DAI) and Analog Audio Interface (AAI). The device also supports left-justified and I2S-bus formats for audio applications.

Power Consumption

The AD5697RBCPZ-RL7 has a low power consumption rating, making it suitable for use in battery-powered systems. In active operating mode, the device consumes 750μA typical, and in standby and power-down modes, it consumes 0.1μA typical. The device supports Direct Memory Access (DMA) capabilities, eliminating the need to dedicate system processor time to data transfers.

Working Principle

The AD5697RBCPZ-RL7 uses a voltage output conversion architecture to generate analog output signals from digital inputs. This architecture consists of an R-2R resistive ladder for digital-to-analog conversion, an integrator for low-pass filtering, a C-LTE amplifier, and an output buffer. The device has an 8-bit accuracy, meaning that it can generate 256 different output levels.

Data is sent to the device in 8-bit byte format, with the MSB being the most-significant bit and the LSB being the least-significant bit. The values from the digital inputs are converted to analog output voltage using the R-2R resistive ladder, then filtered with the integrator, amplified by the C-LTE amplifier, and buffered by the output buffer. The buffered voltage output is then ready to be used by downstream systems.

Conclusion

The AD5697RBCPZ-RL7 is a low-power, 8-bit precision DAC from Analog Devices. It is a suitable solution for digital-to-analog conversion in audio, industrial, and medical monitoring applications. It supports several popular digital input formats, and provides low noise and high linearity, allowing it to achieve accurate analog output voltage over a wide temperature range. The device has an 8-bit accuracy, consuming only 750μA typical in active operating mode.
