Notes:

1 Tester measures code transitions by dithering the voltage of the analog input (VIN). The difference between the measured and the

ideal code width (VREF/1024) is the DNL error (Figure 3.). The INL error is the maximum distance (in LSBs) from the best fit line to

any transition voltage (Figure 4.). Accuracy is a function of the sampling rate (FS).

2 Guaranteed. Not tested.

3 Specified values guarantee functionality, but INL & DNL specifications may not be met.

4 --1 dB bandwidth is a measure of performance of the A/D input stage (S/H + amplifier). Refer to other parameters for accuracy within

the specified bandwidth.

Notes

1 Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a

stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.

2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps

(HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short

3

transients outside the supplies of less than 100mA for less than 100ms.

VDD refers to AVDD and DVDD. GND refers to AGND and DGND.
