Electrical Characteristics

These specifications apply for VSSe50 VDC VGGeb120 VDC VDDe0VDC a reference voltage of 10000 VDC across the

on-chip R-network (VR-NETWORK TOPe5000 VDC and VR-NETWORK BOTTOMeb5000 VDC) and a clock frequency of 800

kHz For all tests a 475X resistor is used from pin 5 to VR-NETWORK BOTTOM eb5VDC Unless otherwise noted these

specifications apply over an ambient temperature range of b55 Cto a125 C for the ADC0800PD and 0 Cto a70 C for the

ADC0800PCD

Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating

the device beyond its specified operating conditions

Note 2

When the input voltage (VIN) at any pin exceeds the power supply rails (VIN k Vb or VIN l Va) the absolute value of current at that pin should be limited

to 5 mA or less The 20 mA package input current limits the number of pins that can exceed the power supply boundaries witha5mA current limit to four

Note 3

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX iJA and the ambient temperature TA The maximum

allowable power dissipation at any temperature is PD e (TJMAX b TA) iJA or the number given in the Absolute Maximum Ratings whichever is lower For this

device TJMAX e 125 C and the typical junction-to-ambient thermal resistance of the ADC0800PD and ADC0800PCD when board mounted is 66 CW

Note 4

Human body model 100 pF discharged through a 15 kX resistor

Note 5

Typicals are at 25 C and represent most likely parametric norm

Note 6

Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level)

Note 7

Design limits are guaranteed but not 100% tested These limits are not used to calculate outgoing quality levels

Note 8

Non-linearity specifications are based on best straight line

Note 9

Guaranteed by design only

Note 10

Start conversion pulse duration greater than 3

clock periods will cause conversion errors
