Serial Port A/D Converter - This circuit is a simple 8-bit
analogue to digital converter circuit which is connects to PC serial port. The circuit is based on TLC548
A/D-converter chip (might be hard to get nowadays, Texas Instruments makes this IC) , which is an A/D-converter
with serial output. The output of the TLC548 is not directly suitable for standard serial data reception. . . .
Serial Port Drives 12 Bit ADC
- 10/12/95 EDN Design Idea The circuit in Fig 1 performs a task that a microcontroller usually performs, that
of driving a 12-bit ADC from the serial port of a PC. Power consumption is low; the 2-mA operating current drops
to only 15 µA in shutdown. . . . [by John Wettroth, Maxim Integrated Products, Sunnyvale, CA]
Setup Tests 68HC11 µP's Internal A/D Converter - 10/13/94 EDN Design Idea The MC68HC11, an 8-bit single-chip microcontroller, features an
on-chip, eight-channel, multiplexed 8-bit A/D converter. But the µC's data sheet specifies merely the A/D
converter's maximum integral nonlinearity and a lower limit for its reference voltage (3V). The test setup in Fig
1, along with appropriate µC software and test stimuli, more thoroughly characterizes the converter. . . . [by

Simple ADC Is Surprisingly Accurate - 06/09/94 EDN Design Idea The reference voltage in Fig 1a's simple rail-to-rail PWM ADC is
the only critical component. The input-voltage range extends from ground to the power rail which also acts as the
reference. The circuit is essentially a variation . . . [by Mike Walne, Farnell Instruments, Wether[by, West

Simple circuit provides precision ADC interface - 08/21/03 EDN Design Idea Real-world measurement requires the extraction of weak signals
from noisy sources. High common-mode voltages are often present even in differential measurements. The usual
approach to this problem is to use an op amp or an instru. . . [by Moshe Gerstenhaber and Charles Kitchin,
