This document describes the ADC0801, ADC0802, ADC0803, ADC0804, and ADC0805, which are CMOS 8-bit successive approximation analog-to-digital converters. These devices utilize a differential potentiometric ladder design compatible with MOS and TTL voltage levels, allowing direct interfacing with the NSC800 and INS80B0A derivative control buses without additional logic.
The datasheet provides detailed specifications including resolution, total error, conversion time, and electrical characteristics for various package types. It covers absolute maximum ratings, operating conditions, AC electrical parameters such as clock frequency and access times, and specific error specifications for each model variant.
| Resolution | 8 bits |
|---|---|
| Total Error (ADC0801) | +/- 2% LSB |
| Conversion Time | 100 us |
| Clock Frequency Range | 640 kHz to 1.46 MHz |
| Analog Input Voltage Range | Gnd-0.05 Vcc to Vcc + 0.05 Vcc |
| Supply Voltage Range | 4.5 Vcc to 6.3 Vcc |
The ADC0801 through ADC0805 are 8-bit successive approximation A/D converters.
No, they appear like memory locations or I/O ports and no interfacing logic is needed.
The typical conversion time is 100 microseconds.
