Description
The ADS7066 is a small, 16-bit, 8-channel, high-precision successive-approximation register (SAR) analog-to-digital converter (ADC). The ADS7066 has an integrated capless reference and a reference buffer that helps reduce the overall solution size by requiring fewer external components. The wafer-level-chip-scale package and fewer external components make this device suitable for space-constrained applications.
The ADS7066 features built-in offset calibration for improved accuracy over wide operating conditions of the system. The programmable averaging filters enable higher resolution measurement. The eight channels of the ADS7066 can be individually configured as analog inputs, digital inputs, or digital outputs that enable smaller system size and simplify circuit design for mixed signal feedback and digital control.
The enhanced-SPI enables the ADS7066 in achieving high throughput at lower clock speeds, thereby simplifying the board layout and lowering system cost. The ADS7066 features a cyclic redundancy check (CRC) for data read and write operations and the power-up configuration.
