ADS7067 16-Bit SAR Analog-to-Digital Converter Texas Instruments ADS7067 16-Bit SAR Analog-to-Digital Converter (ADC) is a small 8-channel, high-precision successive-approximation register (SAR) ADC. The ADS7067 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 device family includes the ADS7067 (800kSPS) and the ADS7066 (250kSPS) speed variants.
