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. https://elecena.pl/product/30551349/8-bit-high-speed-p-compatible-a-d-converter-with-track-hold-function-dw-20-40-to-85 2026-08-01 https://elecena.pl/product/30551349/8-bit-high-speed-p-compatible-a-d-converter-with-track-hold-function-dw-20-40-to-85 2026-08-06
