Application Notes
- Implementing a Direct Thermocouple Interface With MSP430x4xx and ADS1240 (Rev. A)PDF, 195 Kb, Revision: A, File published: Oct 4, 2001
This application report describes and shows how to implement a direct thermocouple interface, without using the signal conditioning circuitry normally required for thermocouples. The thermocouple interfaces directly to the Burr Brown ADS1240, 24-bit ADC from Texas Instruments, Inc. An MSP430F41x ultralow-power microcontroller is used to communicate with the ADC, read the conversion values, convert - Remove the DC Portion of Signals with the ADS7817PDF, 55 Kb, File published: Sep 27, 2000
Unwanted portions of a signal, such as a DC pedestal, can be difficult to reject in a single supply circuit. A DC pedestal voltage most typically appears at the output of an operational amplifier with a small signal riding on top of it. This pedestal voltage is required in the analog domain to insure that the small signal that contains the pertinent information never falls below the ground potenti
