Hi, I was the designer of the board, but I don't remember the part number of the reference. I will try to consult my paper schematic when I get a chance, if no one else can help you. I do remember that I originally used some convenient reference which seemed OK from the data sheet, but turned out to be too noisy. I changed it to a different one.
When asking questions such as this, it is helpful to know why you need to know the part number. Rick Karlquist N6RK On 11/9/2014 12:54 PM, Rob040 . wrote:
Dear time-nuts, Can anyone enlighten me by telling which IC has been used for creating the +2.5V reference voltage on the oscillator board of the E1938?It's the only IC in the diagram where the type number is not mentioned. In a post of years back I found LT1121, but that one is a voltage regulator and is used on the control board.
