national semiconductor ADC0820 8-Bit High Speed P Compatible A/D Converter with Track/Hold Function handbook
The ADC0820 is a CMOS analog-to-digital converter featuring a half-flash conversion technique that provides an 8-bit resolution and a maximum conversion time of 1.5 µs in WR-RD mode. It includes a built-in track-and-hold circuit, eliminating the need for external sample-and-hold components for signals moving at less than 100 mV/µs.
The device is designed to interface easily with microprocessors by appearing as a memory location or I/O port without external logic. It operates on a single +5V supply and offers various package options including DIP, SSOP, and molded chip carriers.
