... DIP and SO packages. Both parts have been trimmed for offset voltage, gain, and linearity fur- ther adjustment is necessary. The MAX515’s buffer is fixed at a gain of 2. The MAX504’s internal op amp may be configured for a gain well as for unipolar or bipolar output voltages. The MAX504 can also be used as a four-quadrant multiplier without external resistors or op amps ...

... DOUT Figure 1. Timing Diagram 8 _______________________________________________________________________________________ _______________Detailed Description The MAX504/MAX515 use an “inverted” R-2R ladder net- FUNCTION work with a single-supply CMOS op amp to convert 10-bit digital data to analog voltage levels (see Functional Diagram) . The term “inverted” describes the ladder net- work because the REFIN pin in current-output DACs is the summing junction, or virtual ground amp ...

... Additionally, the output buffer amplifier exhibits a nonlinearity near-zero output when operating with a single supply. To account for this nonlinearity in the MAX504/MAX515, linearity and gain error are measured from code 3 to code 1023. The output buffer’s offset and nonlinearity do not affect monotonicity, and these DACs are guaranteed monotonic starting with code zero ...
