ADC10321 www.ti.com SNAS028F – JUNE 2000 – REVISED MAY 2013 ADC10321 10-Bit, 20MSPS, 98mW A/D Converter with Internal Sample and Hold Check for Samples: ADC10321 FEATURES DESCRIPTION • • • • • The ADC10321 is a low power, high performance CMOS analog-to-digital converter that digitizes signals to 10 bits resolution at sampling rates up to 25Msps while consuming a typical 98mW from a single 5V supply. Reference force and sense pins allow the user to connect an external reference buffer amplifier to ensure optimal accuracy. No missing codes is ensured over the full operating temperature range. The unique two stage architecture achieves 9.2 Effective Bits with a 10MHz input signal and a 20MHz clock frequency. Output formatting is straight binary coding. 1 2 Internal Sample-and-Hold Single +5V Operation Low Power Standby Mode Ensured No Missing Codes TTL/CMOS or 3V Logic Input/Output Compatible APPLICATIONS • • • • • • • Digital Video Communications Document Scanners Medical Imaging Electro-Optics Plain Paper Copiers CCD Imaging KEY SPECIFICATIONS • • • • • • • • Resolution 10 Bits Conversion Rate 20 Msps ENOB@ 10MHz Input 9.2 Bits (typ) DNL 0.35 LSB (typ) Conversion Latency 2 Clock Cycles PSRR 56 dB Power Consumption 98 mW (typ) Low Power Standby Mode
