Supply Voltages)

GENERAL DESCRIPTION

The MP3274 is a complete 32-channel, 12-bit Data Acquisi-

tion Subsystem with 3-state output buffers for direct interfacing

to 16-bit microprocessor buses. Implemented using an ad-

vanced BiCMOS process, the converter combines a32-channel

passiveovervoltageprotectedmultiplexerinstrumentationamp,

a sample & hold, a SAR, a 12-bit decoded D/A, a comparator, a

precision reference and the control logic to achieve an accurate,

repeated conversion in less than 15µs, and a mux/instrumenta-

tion amp settling period of less than 10µs.

condition can exist on unselected channels without disrupting

the measured channel or operation of the MP3274! The internal

4 V reference has sufficient output current to provide other sys-

temreferenceneeds. Precisionthinfilmscalingandoffsetresis-

tors are laser trimmed to provide for less than 2 LSB INL for +10

V inputs on all channels.

In addition, the MP3274 will output either full scale (0111 ....)

for overrange and – full scale (1000....) for underrange condi-

tions. This greatly simplifies microprocessor software develop-

ment.

A unique input design provides input overvoltage protection

to ꢀ50 V over the supply voltages. Therefore, an overvoltage
