Data Acquisition - Digital to Analog Converters (DAC) are used to convert digital signals into analog signals. The AD7805BRSZ is an affordable, low-power 10-bit multi-channel DAC that is capable of transforming digital signals into analog signals with an accurate resolution of 0.25 LSB (Least Significant Bit). This product is able to produce 12 different output ranges and is packed with features including a built-in reference and an input latch.

Application Field

The AD7805BRSZ is designed to be used in a broad range of applications, including medical, industrial and automotive. It is ideally suited for applications that require high resolution analog output such as motor control, programmable logic controllers (PLCs), analog signal generation, and audio/video systems.

The AD7805BRSZ is suitable for use in medical systems where its high tolerance for EMI and power disturbances make it an attractive solution. It is also capable of withstanding harsh environments, making it suitable for use in industrial and automotive control systems.

Working Principle

The AD7805BRSZ is a multi-channel DAC whose design is based on a 10-bit R-2R architecture. The main functional blocks are the reference circuit, the latch, the reference amplifier, and the R-2R resistor network. The AD7805BRSZ has been designed to provide a high degree of accuracy and dynamic performance over a wide range of supply voltages.

The reference circuit is used to generate a stable reference voltage that is used to set the R-2R resistor network’s reference voltage. The latch is used to convert the digital input signals into an analog signal. The reference amplifier is used to amplify the output of the DAC. The R-2R resistor network is used to convert the analog signal into the desired voltage output.

The AD7805BRSZ is designed for low power consumption. It utilizes a low voltage CMOS process which allows for a typical power consumption of only 1.2 mW. It is also designed to be extremely flexible, allowing users to customize the output range of the DAC from +1.25 V to +6.0 V.

The AD7805BRSZ is capable of producing accurate analog outputs with a resolution of up to 0.25 LSB. It is also capable of rejecting EMI and withstand power disturbances, making it an ideal solution for use in demanding environments.
