AD01-D 10 Bit A/D Converter Subsystem

This document provides the technical specifications and operational details for the AD01-D analog-to-digital (A/D) converter subsystem, which is designed to interface with the PDP-11 computer. Key information covered includes:

• General Description: The subsystem features a 10-bit A/D converter with programmable gain (1, 2, 4, 8) and a single-ended multiplexer supporting up to 32 channels.
• Interface & Programming: Software control is handled via two registers: the Control and Status Register (ADCS) and the Data Buffer (ADDB), with details on register bit assignments for operations such as channel selection, interrupts, and gain control.
• Hardware Requirements: Specifies the necessary power supplies (H727 and H716B) and mechanical configuration for rack mounting.
• Technical Performance: Details system accuracy (0.1%), input ranges, conversion speeds (22µsec to 29µsec), and external clock control logic for synchronization.
• Wiring & Pinouts: Includes comprehensive pin assignment tables for analog-channel input.
