DM2502 DM2503 DM2504 Successive Approximation
Registers
General Description
The DM2502 DM2503 and DM2504 are 8-bit and 12-bit
TTL registers designed for use in successive approximation
A D converters These devices contain all the logic and
control circuits necessary in combination with a D A con-
verter to perform successive approximation analog-to-digital
conversions
The DM2502 has 8 bits with serial capability and is not ex-
pandable The DM2503 has 8 bits and is expandable with-
out serial capability The DM2504 has 12 bits with serial
capability and expandability
All three devices are available in ceramic DIP ceramic flat-
pak and molded Epoxy-B DIPs The DM2502 DM2503 and
DM2504 operate over b55 C to a125 C the DM2502C
DM2503C and DM2504C operate over 0 C to a70 C
Features
Y Complete logic for successive approximation A D con-
verters
Y 8-bit and 12-bit registers
Y Capable of short cycle or expanded operation
Y Continuous or start-stop operation
Y Compatible with D A converters using any logic code
Y Active low or active high logic outputs
Y Use as general purpose serial-to-parallel converter or
ring counter
