The ADC0820CCN/NOPB is an 8-bit high speed μP compatible Analog-to-digital Converter (ADC) with built-in track/hold function. By using a half-flash conversion technique, the CMOS A/D offers a 1.5μs conversion time and dissipates only 75mW of power. The half-flash technique consists of 32 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the ADC is tracked and held by the input sampling circuitry eliminating the need for an external sample-and-hold for signals moving at less than 100mV/μs. For ease of interface to microprocessors, the ADC has been designed to appear as a memory location or I/O port without the need for external interfacing logic.
