... ENVIRONMENTAL SPECIFICATIONS Temperature Range: Specification Storage * Specifications same as DAC729JH. NOTES: (1) TTL- and CMOS-compatible. (2) Specified for V FSR means full-scale range, 20V for 10V range, etc. (5) Adjustable to zero error with an external potentiometer. (6) COB is complementary offset binary (bipolar); CSB is complementary straight binary (unipolar). (7) Using the MSB adjustment circuit, the user may improve the DAC linearity to 1/2LSB of this specification with gain and offset errors adjusted to zero (8) Maximum represents 3 limit, not 100% production tested. (9) At the major carry ...

ELECTROSTATIC DISCHARGE SENSITIVITY Any integral circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance ...

ACCURACY Linearity This specification describes one of the most important mea- sures of performance of a D/A converter. Linearity error is the deviation of the analog output versus code transfer function from a straight line drawn through the end points ...

... The suggested network for adjusting the linearity is shown in Figure 12. This circuit has nearly twice the range that is required for the DAC729JH. The range is intentionally narrow minimize the effect of temperature drift or stability problems in the potentiometers. The potentiometers are biased in an ...
