... Serial P interface Single supply operation: 2.7V-5.5V Setting read-back without effecting outputs DESCRIPTION The CAT513 is a dual 8-Bit Memory DAC designed as an electronic replacement for mechanical potentiometers and trim pots. Intended for final calibration of products such as camcorders, fax machines and cellular tele- phones on automated high volume production lines ...

... CLOCK The CAT513’s clock controls both data flow in and out of the IC and EEPROM memory cell programming. Serial data is shifted into the DI pin and out of the DO pin on the clock’s rising edge. While it is not necessary for the clock ...

... DATA OUTPUT Data is output serially by the CAT513, LSB first, via the Data Out (DO) pin following the reception of a start bit and two address bits by the Data Input (DI). becomes active whenever CS goes high and resumes its high impedance Tri-State mode when CS returns low ...

... EEPROM then a change would occur at the read cycle’s conclusion. TEMPORARILY CHANGE OUTPUT The CAT513 allows temporary changes in DAC’s output to be made without disturbing the settings retained in EEPROM memory. This feature is particularly useful when testing for a new output setting and allows for user adjustment of preset or default values without losing the original factory settings ...
