Each of the eight analog input channels can be individually configured for single-ended or pseudo-differential operation, with software-selectable input ranges of plus\/minus 10V, plus\/minus 5V, plus\/minus 2.5V, or 0 to 10V. This flexibility eliminates the need for external signal conditioning amplifiers and attenuators in many industrial applications. The device operates from a combination of supply rails: AVCC=+12V and VSS=-12V for the analog section, with DVCC=+5V and VCC=+5V for the digital section. An on-chip 2.5V reference is provided, or an external reference can be used for higher accuracy. The SPI-compatible serial interface supports clock rates up to 50MHz, enabling fast data transfer to the host MCU or FPGA.","working_principle":"The AD7328BRUZ-REEL7 uses a successive approximation register (SAR) architecture with a capacitive DAC. The conversion process begins when the CS# pin is asserted and the write register is loaded via the DIN line. The selected input channel is sampled on the internal hold capacitor, and the SAR performs a binary search over 12 clock cycles to determine the digital output code. In sequencer mode, the device automatically steps through a programmable sequence of channels, eliminating the need for the host to write a new channel address for each conversion. The input range for each channel is independently programmable through the control register, allowing the same device to measure both high-voltage industrial signals and low-voltage sensor outputs. Input overvoltage protection clamps the analog inputs to plus\/minus 16.5V regardless of the supply voltage state.","pin_description":"\n
