AN9D, AN9E, AN9F Series

Analog master slice IC series

s Overview

The AN9D, AN9E and AN9F series are master slice ICs of bipolar process, which enables you to integrate an analog

circuit easily onto a single chip. A custom IC can be made by placing a wired pattern designed in line with the customer's

analog circuit onto a master slice.

Starting from a wafer on which a most part of IC diffusion processes are already finished, you can shorten an IC pilot

fabrication considerably. Further, placement of elements and inter-element wiring are done automatically by a com-

puter, which results in short period of pattern designing and thereby developing a custom IC in a short period.

s Features

• High design flexibility

• Easy circuit constant design because of setting resistance or capacitance to an arbitrary value.

• Free setting of contacts between a substrate and GND wiring prevents from operation error to be caused by floating

of substrate potential.

• Usable for multi power source because a resistor island potential can be set for each unit.

• Builds in a lateral type PNP transistor of high reverse breakdown voltage between base and emitter, or a collector

wall type NPN transistor of excellent saturation characteristics. (AN9DA00, AN9DB00, AN9DF00)

• Short development period

• Due to a full automatic layout design, a sample is available in one month from a completion of a circuit diagram.

• Applicable to a small quantity production item

• Possible to develop a custom IC for small quantity production due to a low development cost.
