GENERAL DESCRIPTION
The ADD8502 is an integrated, high accuracy, programmable
grayscale generator. Two sets of five output reference voltages
are mask programmed to 0.2% resolution. The outputs switch
between the two sets of five levels. The reference levels are selected
from a 512 tap resistor network using a via mask.
ADD8502 includes two serially addressable, 10-bit digital-to-
analog converters (DACs) and five fast, low current buffers.
The dual DACs set the endpoint voltages applied to the resistor
network to adjust for flicker and range. The two power save modes
can reduce the total current to less than 1
μ
A and feature fast
recovery time from Shutdown/Sleep Mode. The ADD8502
accepts CMOS or TTL inputs for all controls, including the
common drive circuit levels.
ADD8502 operates over the industrial temperature range from
–40
°
C to +85
°
C and is available in a space-saving 24-lead
4 mm
4 mm frame chip scale package.
