FEATURES
DESCRIPTION
23
Three operating modes: 12-bit + sign, 8-bit +
The LM12458, and LM12H458 are highly integrated
sign, and “watchdog”
Data Acquisition Systems. Operating on just 5V, they
Single-ended or differential inputs
combine a fully-differential self-calibrating (correcting
Built-in Sample-and-Hold and 2.5V bandgap
linearity and zero errors) 13-bit (12-bit + sign) analog-
reference
to-digital converter (ADC) and sample-and-hold (S/H)
with
extensive
analog
functions
and
digital
Instruction RAM and event sequencer
functionality. Up to 32 consecutive conversions, using
8-channel multiplexer
two's complement format, can be stored in an internal
32-word conversion FIFO
32-word (16-bit wide) FIFO data buffer. An internal 8-
word RAM can store the conversion sequence for up
Programmable acquisition times and
to eight acquisitions through the LM12(H)458's eight-
conversion rates
input multiplexer. The obsolete LM12454 has a four-
Self-calibration and diagnostic mode
channel multiplexer, a differential multiplexer output,
8- or 16-bit wide data bus microprocessor or
and a differential S/H input. The LM12(H)458 can
DSP interface
also operate with 8-bit + sign resolution and in a
supervisory “watchdog” mode that compares an input
signal against two programmable limits.
APPLICATIONS
Programmable acquisition times and conversion rates
Data Logging
are possible through the use of internal clock-driven

generated for absolute or ratiometric operation or can

Inertial Guidance
All registers, RAM, and FIFO are directly addressable

through the high speed microprocessor interface to
either an 8-bit or 16-bit data bus. The LM12(H)458
