ADS7809U

16位10μs串行CMOS采样模拟数字转换器 16-Bit 10μs Serial CMOS Sampling ANALOG-TO-DIGITAL CONVERTER

DESCRIPON

The ADS7809 is a complete 16-bit sampling Analog-to-Digital A/D converter using state-of-the-art CMOS structures. It contains a 16-bit capacitor-based Successive Approximation Register SAR A/D converter with sample-and hold, reference, clock, and a serial data interface. Data can be outputted using the internal clock, or can be synchronized to an external data clock. The ADS7809 also provides an output synchronization pulse for ease of use with standard DSP processors.
