NOTES: (1) Input = low level (less than 1% of Full Scale); Full Scale I

provided input resistor, R

+. See Section 7 for recommended connections. (6)

Straight Binary output code has slightly different Charge Range. See Section 6. (8) Input offset voltage is nulled by autozero circuitry and causes no output error. See Section 6 (Internal Error Correction). (9) This is

the maximum clock frequency at which SETUP codes can be written to and read from the DDC101. (10) For other input current and voltage configurations, see Discussion of Specifications and Detailed Theory of Operation

sections. (11) A best-fit straight line method is used to determine linearity. Two different best-fit straight lines are used for the two unipolar integral linearity specifications. Acquisition Time = 16 clock cycles, Oversampling

= 128.

ELECTROSTATIC

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown

recommends that all integrated circuits be handled with ap-

propriate precautions. Failure to observe proper handling and

installation procedures can cause damage.

ESD damage can range from subtle performance degradation

to complete device failure. Precision integrated circuits may

be more susceptible to damage because very small parametric

changes could cause the device not to meet published

specifications.
