These converters perform APPLICATIONS 10-bit conversion in two lower-resolution “flashes”, yielding a fast A/D without the cost, power • Digital Signal Processor Front Ends consumption, and other problems associated with • Instrumentation true flash approaches. Dynamic performance (THD, • Disk Drives S/N) is ensured. • Mobile Telecommunications The analog input voltage is sampled and held by an internal sampling circuit. Input signals at frequencies KEY SPECIFICATIONS from DC to over 200 kHz can, therefore, be digitized accurately without the need for an external sample- • Conversion Time 600 ns (Typical) and-hold circuit. • Sampling Rate 800 kHz The ADC10462 and ADC10464 include a “speed-up” • Low Power Consumption 235 mW (Max) pin. Connecting an external resistor between this pin • Total Harmonic Distortion (50 kHz) −60 dB and ground reduces the typical conversion time to as (Max) little as 350 ns with only a small increase in linearity error. • No Missing Codes Over Temperature For ease of interface to microprocessors, the ADC10461, ADC10462, and ADC10464 have been designed to appear as a memory location or I/O port without the need for external interface logic.
