ADC08D502 www.ti.com SNOSC85A – AUGUST 2012 – REVISED APRIL 2013 ADC08D502 High Performance, Low Power, Dual 8-Bit, 500 MSPS A/D Converter Check for Samples: ADC08D502 FEATURES 1 2 Internal Sample-and-Hold Single +1.9V ±0.1V Operation Choice of SDR or DDR Output Clocking Multiple ADC Synchronization Capability Specified No Missing Codes Serial Interface for Extended Control Fine Adjustment of Input Full-Scale Range and Offset Duty Cycle Corrected Sample Clock APPLICATIONS Direct RF Down Conversion Digital Oscilloscopes Satellite Set-top boxes Communications Systems Test Instrumentation KEY SPECIFICATIONS Resolution: 8 Bits Max Conversion Rate: 500 MSPS (min) Bit Error Rate: 10-18 (typ) ENOB @ 250 MHz Input: 7.5 Bits (typ) DNL: ±0.15 LSB (typ) Power Consumption – Operating: 1.4 W (typ) – Power Down Mode: 3.5 mW (typ) DESCRIPTION The ADC08D502 is a dual, low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 bits resolution at sampling rates up to 500 MSPS. Consuming a typical 1.4 Watts at 500 MSPS from a single 1.9 Volt supply, this device is specified to have no missing codes over the full operating temperature range. The unique folding and interpolating architecture, the fully differential comparator design, the innovative design of the internal sample-and-hold amplifier and the selfcalibration scheme enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.5 ENOB with...
