Data Acquisition – Digital to Analog Convertors (DAC) has been widely utilized for many industrial, commercial, and military purposes that necessitates transforming digital data into an analog signals. The ADV7127KRU50 represents a 12-bit 8-Channel Voltage output, Serial Digital Interface Multi-channel DAC designed for both low frequency and pulse-width modulated (PWM) applications. It offers a single +5V power supply and high flexibility in the interface data structure.

The ADV7127KRU50 is a low-power, multi-channel DAC with a voltage output in the range of +2.56V±0.512V. It operates with a single +5V power supply and requires external resistors to create an output voltage range. It accepts 8-bit input data in either binary, dual slope, or Gray code formats, which is transmitted serially via the LD pin. The device is a pin- and space-saving alternative to traditional DACs, making it ideal for applications such as Analog-to Digital Converters (ADCs, ATE, and DAQs).

The ADV7127KRU50 operates as a voltage output DAC with a wide output range of +2.56V±0.512V. It is suitable for low frequency and pulse-width modulated (PWM) applications and accepts 8-bit input data with a variety of data input formats. It features multiple power management modes that help conserve energy when operating at low sample rates. It also features a low input impedance which allows the device to be used for both Adjustable Gain Amplifiers (AGA) and non-AGA applications. Additionally, the ADV7127KRU50 can be used as part of a voltage-output DAC or as part of a high-output current-output DAC/ADC combination.

The working principle of the ADV7127KRU50 is simple. When an 8-bit serial data is applied at the LD pin and clocked with the LD_CLK pin, the 12-bit output of the device is digitally reconfigured. The device utilizes a wide range of data input formats like binary, dual slope and Gray code, whereby the former is the most commonly used format for data conversion. Data is fed into the converter 8 bits at a time and the 12-bit DAC output voltage is produced. The device is configured by two control registers that output the 8-bit data and allow data out at control pin CS.

The ADV7127KRU50 is ideal for many applications such as interchangeable industrial controls such as motion regulators, position displays, rotary switches, and medical imaging systems. Additionally, it is suitable for ATE systems, DAC/ADC combinations, embedded and standalone data acquisition systems, analog-to-digital and digital-to-analog converters, and voltage sensors and transducers. The ADV7127KRU50 is designed and verified to operate over an extended industrial temperature range of -40°C to +85°C and is available in a space-saving 56-pin TQFP and 32-pin TSSOP package.

In conclusion, the ADV7127KRU50 is a low-power, voltage output, 8-channel DAC designed for both low frequency and pulse-width modulated (PWM) applications. It offers both a single +5V power supply and wide flexibility in the interface data structure with up to 8-bit data acceptance. Additionally, the device features a wide output range of +2.56V±0.512V and multiple power management modes that conserve energy when operating at low sample rates. The ADV7127KRU50 is suitable for many industrial, commercial, and military applications that requires data conversion and is available in either a 56-pin TQFP or 32-pin TSSOP package.
