Philips Semiconductors Linear Products Product specification 8-Bit, high-speed, µP-compatible A/D converter with track/hold function ADC0820 DESCRIPTION By using a half-flash conversion technique, the 8-bit ADC0820 CMOS A/D offers a 1.
5µs conversion time while dissipating a maximum 75mW of power.
The half-flash technique consists of 31 comparators, 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 slewing at less than 100mV/µs.
For ease of interface to microprocessors, the ADC0820 has been designed to appear as a memory location or I...
