PIN FUNCTIONS REFOUT2 (Pin 26):
Reference Buffer 2 Output. An onboard
REFRTN2 (Pin 27):
Reference Buffer 2 Output Return. buffer nominally outputs 4.096V to this pin. This pin is Bypass REFRTN2 to REFOUT2. Do not tie the REFRTN2 referred to REFRTN2 and should be decoupled closely to pin to the ground plane. the pin (no vias) with a 0.1µF (X7R, 0402 size) capacitor
REFINT (Pin 28):
Reference Buffer Output Enable. Tie to and a 10μF (X5R, 0805 size) ceramic capacitor in paral- V lel. The internal buffer driving this pin may be disabled DD when using the internal reference. Tie to ground to disable the internal REFOUT1 and REFOUT2 buffers for by grounding the REFINT pin. If the buffer is disabled, use with external voltage references. This pin has a 500k an external reference may drive this pin in the range of internal pull-up to V 1.25V to V DD. DD.
Exposed Pad (Pin 29):
Ground. Solder this pad to ground. 232314fb For more information http://www.linear.com/LTC2323-14 9 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Converter Characteristics Dynamic Accuracy Internal Reference Characteristics Digital Inputs And Digital Outputs Power Requirements ADC Timing Characteristics Typical Performance Characteristics Pin Functions Functional Block Diagram Timing Diagram Applications Information Package Description Revision History Typical Application Related Parts
