Data Acquisition - Digital to Analog Converters (DAC)
Digital to Analog Converters (DAC) are commonly used to convert digital data into a continuous analog voltage. They play an important role in a variety of applications, such as data acquisition, instrumentation, and audio applications. The ADV7123SCP170EP-RL is a high-speed, 18-bit voltage-output digital-to-analog converter (DAC) with 74dB of spurious-free dynamic range (SFDR) and power-on reset.Application Field:
The ADV7123SCP170EP-RL is ideal for consumer video, video/graphics, cable set-top boxes, LCD TV ADCs/DACs with non-distorting outputs, multi-standard video decoders, and professional/industrial audio systems. It is used in a variety of applications, such as data acquisition systems, instrumentation, audio systems, and video/graphics.Working Principle:
The ADV7123SCP170EP-RL is an 18-bit voltage output digital-to-analog converter (DAC) that supports a wide range of supply voltages and temperature ranges. The device incorporates power saving features to reduce power consumption. It also features a low-glitch digital architecture, reducing settling time by up to 50%. Additionally, the ADV7123SCP170EP-RL is capable of achieving 74dB of spurious-free dynamic range (SFDR).The ADV7123SCP170EP-RL features a unique “Automatic Output Range Select” mode that reduces system complexity. This is operated by clocking in a special code word to the PATTERN_IN input pin, then the device determines an optimal output range. This eliminates the need to externally select a range, thus reducing power consumption while still providing a reliable output swing.The ADV7123SCP170EP-RL utilizes an on-board 3.3V linear regulator, so only one supply is needed to power the device. This reduces board space and simplifies board design. Additionally, the device contains an external reset pin, which can be used to ensure accurate startup conditions for the DAC. This pin can also be used for system-level power sequencing of multiple DACs. The ADV7123SCP170EP-RL outputs 18 bits of resolution providing a dynamic output from -10V to +10V. The device has a power-on reset circuitry that is used for powering up the DAC in a known state, thus providing better system control. The device also features an optional external reset pin that can be used for system level power sequencing of the DACs and to ensure accurate start-up conditions.The ADV7123SCP170EP-RL has an accuracy of 1% over full specified temperature range, providing superior performance over a wide range of applications. It also features a 1.5KHz data rate, a high signal-to-noise ratio (SNR) of 86dB, and wide speed/power consumptions ranges. In summary, the ADV7123SCP170EP-RL is an ideal choice for a variety of applications that require high accuracy, low power consumption, and superior performance over a wide range of operating conditions. It is capable of providing a wide output range and excellent signal integrity. Additionally, the device provides a power saving feature, power-on reset and external reset pin, allowing for better system control and accuracy.
