ADC0820 8-Bit High Speed µP patible A/D Converter with Track/Hold Function June 1999 ADC0820 8-Bit High Speed µP patible A/D Converter with Track/Hold Function General Description By using a half-flash conversion technique, the 8-bit ADC0820 CMOS A/D offers a 1.5 µs conversion time and dissipates only 75 mW of power. The half-flash technique consists of 32 parators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the ADC0820 is tracked and held by the input sampling circuitry eliminating the need for an external sample-and-hold for signals moving at less than 100 mV/µs. For ease of interface to microprocessors, the ADC0820 has been designed to appear...
