Note 6:
Typical RMS noise at code transitions. may cause permanent damage to the device. Exposure to any Absolute
Note 7:
Parameter tested and guaranteed at OVDD = 2.5V. All input signals Maximum Rating condition for extended periods may affect device are specified with tr = tf = 1ns (10% to 90% of OVDD) and timed from a reliability and lifetime. voltage level of OVDD/2.
Note 2
: All voltage values are with respect to ground.
Note 8:
All timing specifications given are with a 10pF capacitance load.
Note 3:
When these pin voltages are taken below ground or above VDD Load capacitances greater than this will require a digital buffer. (AIN, REF) or OVDD (SCK, CONV, SDO) they will be clamped by internal

Note 10:
Guaranteed by design, not subject to test. or above VDD or OVDD without latch-up.
Note 11:
Recommended operating conditions.
Note 4:
VDD = 5V, OVDD = 2.5V, fSMPL = 2.5MHz, fSCK = 90MHz, AIN = –1dBFS and internal reference unless otherwise noted.
Note 5:
Integral nonlinearity is defined as the deviation of a code from a straight line passing through the actual endpoints of the transfer curve. The deviation is measured from the center of the quantization band. 231314fb For more information www.linear.com/LTC2313-14 5 Document Outline Features Applications Description Typical Application Absolute Maximum Ratings Pin Configuration Order Information Electrical Characteristics Converter Characteristics Dynamic Accuracy Reference Input/Output Digital Inputs and Digital Outputs Power Requirements ADC Timing Characteristics Typical Performance Characteristics Pin Functions Block Diagram Timing Diagrams Applications Information Package Description Related Parts
