It integrates six independent 16-bit ADC cores organized as three simultaneously sampling pairs, each controlled by its own CONVST signal. The device accepts true bipolar input signals in \u00b110V or \u00b15V ranges, selectable via pin or software. An internal 2.5V reference with buffer eliminates the need for an external reference in most applications. The AD7656 provides both a high-speed parallel interface and a serial interface (SPI\/QSPI\/MICROWIRE\/DSP-compatible) with daisy-chain capability, making it versatile for different processor architectures. At only 140mW power consumption at 250kSPS, it is well-suited for power-sensitive industrial and instrumentation applications.","working_principle":"The AD7656 operates through four key subsystems. (1) The analog input stage uses on-chip wideband track-and-hold amplifiers that simultaneously sample the six analog inputs when triggered by the CONVST signals. The input range is selectable between \u00b14xVREF (\u00b110V) and \u00b12xVREF (\u00b15V) via the RANGE pin or software control. (2) The six SAR ADC cores perform 16-bit successive approximation conversion simultaneously within each pair, controlled by the CONVST A\/B\/C signals and an internal oscillator. Each conversion takes approximately 3\u03bcs, enabling the 250kSPS throughput rate. (3) The internal 2.5V reference provides the precision voltage for the DAC networks within each SAR core, with an on-chip buffer that can drive the reference input of multiple ADCs. (4) The data interface subsystem supports both parallel mode (using 16-bit data bus with RD\/WR\/CS control) and serial mode (SPI-compatible with daisy-chain capability for multi-device systems).","pin_description":"
