ADC0820-N datasheet



By using a half-flash conversion technique, the 8-bit ADC0820-N CMOS A/D offers a 1.5 µs conversion time and dissipates only 75 mW 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 ADC0820-N 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-N has been designed to appear as a memory location or I/O port without the need for external interfacing logic.


1. Built-In Track-and-Hold Function

2. No Missing Codes

3. No External Clocking

4. Easy Interface to All Microprocessors, or Operates Stand-Alone

5. No Zero or Full-Scale Adjust Required
