The AD7854BRZ is an integrated circuit (IC) component manufactured by Analog Devices, a leading semiconductor company. It belongs to the AD7854 family of simultaneous sampling analog-to-digital converters (ADCs) and offers high performance conversion capabilities with various features.
The AD7854BRZ is a 14-bit, 400 kilosamples per second (ksps) ADC that incorporates six input channels, making it suitable for applications requiring multi-channel signal digitization. The device also has a built-in sequencer that automatically selects and digitizes the desired channel inputs, ensuring accurate and reliable results.
One key feature of the AD7854BRZ is its simultaneous conversion capability. It can convert all the selected channels at the same time, ensuring precise alignment between the different channels. This feature is particularly important in system designs where synchronized measurements of multiple analog signals are required.
Additionally, the AD7854BRZ provides an on-chip selectable reference voltage, eliminating the need for an external reference component. This allows for convenient and space-efficient integration within various system designs.
The component supports both serial peripheral interface (SPI) and three-wire serial communication protocols for easy interfacing with microcontrollers and digital signal processors. It also features a conversion start command, providing control flexibility over the conversion process.
The AD7854BRZ incorporates a programmable gain amplifier (PGA) that allows for input signal amplification to enhance measurement resolution and accommodate a wide range of input signal magnitudes
