NOTES: (1) Input = low level (less than 1% of Full Scale); Full Scale I_IN = 500nA; T_INT = 1ms; Unipolar Input Range; Acquisition Time = 16 clock cycles, Oversampling = 128. (2) Voltage input is converted through user
provided input resistor, R . (3) FSR is Full Scale Range. (4) Gain Drift does not include the drift of the external reference. (5) V + must be less than or equal to V +. 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.

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.
The information provided herein is believed to be reliable; however, BURR-BROWN assumes no responsibility for inaccuracies or omissions. BURR-BROWN assumes
no responsibility for the use of this information, and all use of such information shall be entirely at the user’s own risk. Prices and specifications are subject to change
without notice. No patent rights or licenses to any of the circuits described herein are implied or granted to any third party. BURR-BROWN does not authorize or warrant
any BURR-BROWN product for use in life support devices and/or systems.
