ANALOG-TO-DIGITAL CONVERTER
Check for Samples: ADS8519 FEATURES DESCRIPTION The ADS8519 is a complete 16-bit sampling
analog-to-digital (A/D) converter using state-of-the-art
CMOS structures. It contains a complete 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 output using the internal clock or synchronized to
an external data clock. The ADS8519 also provides
an output synchronization pulse for ease-of-use with
standard DSP processors. 1 23 0V to 8.192V, В±5V, and В±10V Input Ranges
93dB SNR with 20kHz Input
В±1.5LSB Max INL
В±1LSB Max DNL; 16 Bits, No Missing Codes
