contains the ALD500R/ALD521D A/D Converter chipset that directly plugs into the parallel printer port

of a PC computer. It features calibrated analog input (w/scalable input ranges), and digital circuitry to

communicate with PC or other microprocessors. It is designed to be used as a stand-alone, embedded

system component in a variety of applications including digital panel meters, customized instrumentation

displays, temperature monitoring, high resolution DVM’s, weigh scales and others. Direct Full-scale

analog input range is +/- 2.00000 V DC with a linearity of 0.005%. ALD's 18-bit plus sign integrating

dual-slope analog processor (ALD500) functions as the input device and the ALD521D microprocessor

IC implements the digital conversion, control mode and I/O functions.

configurations, are: Mode A version- calibrated reference and Mode B version – ratio-metric. Mode A is

used primarily for measurements against a calibrated reference voltage typically required in precision

voltmeter applications. Mode B is intended for measurements against a ratio-metric reference voltage

such as those required in weigh scale applications. Standard Mode A version is available as MB1S. Mode

B is a simple application specific adaptation of the standard MB1S.

The MB1S board has provision for PC interface, included DOS setup, operating and calibration software,

Basic programming interface modules, and input resistor divider network for input scaling. DC Inputs are

single ended or optionally fully differential, and features automatic zero and automatic input polarity

detection. A DB25 connector is provided on-board to conveniently interconnect the MB1S to a personal

computer (PC) via the parallel printer port for operation, initial setup and calibration.
