16 bit ADC provides 19 bit resolution: 02/21/2002 EDN -
Design Ideas / Many data-acquisition systems require both
high accuracy and a fast acquisition rate. These attributes
allow the system to detect small data signals and to group more
sensor channels into the same system. With more channels, the
system can be smaller, less expensive, and less power-consuming.
Long-distance optical communications and medical equipment, such
as CT scanners, can benefit from... . |
18 bit ADC uses PC's serial port: 09/27/2001 EDN - Design
Ideas / A PC usually requires a plug-in ADC card to process
analog signals. However, with the circuitry in Figure 1, a PC
can communicate with an 18-bit ADC through its serial port. The
port provides both positive and negative power supplies as well
as control signals. IC1 is an 18-bit MAX132 ADC with a serial
interface. |

ADC enables temperature compensated weigh scale measurements:
07/05/2001 EDN - Design Ideas / You can provide
temperature compensation in weigh-scale applications by
simultaneously measuring both the temperature of the bridge and
the primary output of the bridge transducer. Traditionally, an
integrated multiplexer connects multiple input variables to a
single sigma-delta ADC. Each time the multiplexer switches the
input, the ADC must flush the digital filter of all data
pertaining to t.... |

Analog input circuit serves any microcontroller: 12/20/2001
EDN - Design Ideas / The simple ADC in Figure 1 is perfect for
getting analog signals into a purely digital microcontroller.
Using just five surface-mount parts, you can assemble it for
less than 50 cents (1000), which is approximately half the cost
of a single-chip-ADC approach in the same volume. Moreover, this
design takes only one pin from the microcontroller to operate. . |

Circuit provides reference for multiple ADCs: 01/24/2002
EDN - Design Ideas / The achievable accuracy for systems with
multiple ADCs depends directly on the reference voltages applied
to the ADCs. Medical-ultrasound-imaging systems, for example,
commonly include a large number of ADCs in the system's
beam-former electronics, with the ADCs usually organized in
groups of 16, 24, 32, and so on. . |

Improved amplifier drives differential input ADCs:
01/10/2002 EDN - Design Ideas / ADCs with differential inputs
are becoming increasingly popular. This popularity isn't
surprising, because differential inputs in the ADC offer several
advantages: good common-mode noise rejection, a doubling of the
available dynamic range without doubling the supply voltage, and
cancellation of even-order harmonics that accrue with a
single-ended input. . |

EDN-Design Ideas / 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
instrumentation amplifier and then perform some type of lowpass-filtering
to reduce the background noise level.... |
