    REF1004 1.2V and 2.5V Micropower
    VOLTAGE REFERENCE
    FEATURES DESCRIPTION в—Џ INITIAL ACCURACY:
    REF1004-1.2 В±4mV
    REF1004-2.5 В±20mV
    в—Џ MINIMUM OPERATING CURRENT:
    REF1004-1.2 10ВµA
    REF1004-2.5 20ВµA
    в—Џ EXCELLENT LONG TERM
    TEMPERATURE STABILITY
    в—Џ VERY LOW DYNAMIC IMPEDANCE
    в—Џ OPERATES UP TO 20mA
    в—Џ PACKAGE: 8-Lead SOIC The REF1004-1.2 and REF1004-2.5 are two terminal
    bandgap reference diodes designed for high accuracy
    with outstanding temperature characteristics at low
    operating currents. Prior to the introduction of the
    REF1004 Micropower Voltage References, accuracy
    and stability specifications could only be attained by
    expensive screening of standard devices. The REF1004
    is a cost effective solution when reference voltage
    accuracy, low power, and long term temperature stability are required.
    REF1004 is a drop-in replacement for the LT1004 as
    well as an upgraded replacement of the LM185/385 ...

    Implementing a Direct Thermocouple Interface With MSP430x4xx and ADS1240 (Rev. A)
    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 ADS7817
    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
