ADS7809U/1KE4

16 位 10us 串行 CMOS 采样模数转换器 20-SOIC -40 to 85

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.
