and-holds. On-chip serial ports allow efficient data trans-
fer to a wide range of microprocessors and microcontrol-
lers. These circuits can provide a complete data acquisi-
tion system in ratiometric applications or can be used with
an external reference in others.
The high impedance analog inputs and the ability to
operate with reduced spans (below 1V full scale) allow
direct connection to sensors and transducers in many
applications, eliminating the need for gain stages.
An efficient serial port communicates without external
hardware to most MPU serial ports and all MPU parallel
I/O ports allowing eight channels of data to be transmitted
over as few as three wires. This, coupled with low power
consumption, makes remote location possible and facili-
tates transmitting data through isolation barriers.
Temperature drift of offset, linearity and full-scale error
are all extremely low (1ppm/°C typically) allowing all
grades to be specified with offset and linearity errors of
±0.5LSB
maximum over temperature. In addition, the A
grade devices are specified with full-scale error and total
unadjusted error (including the effects of offset, linearity
and full-scale errors) of
±1LSB
maximum over tempera-
ture. The lower grade has a full-scale specification of
±2LSB
for applications where full scale is adjustable or
less critical.

1091/LTC1092/LTC1093/LTC1094 10-bit data
acquisition systems are designed to provide complete
function, excellent accuracy and ease of use when digitiz-
ing analog data from a wide variety of signal sources and
transducers. Built around a 10-bit, switched capacitor,
successive approximation A/D core, these devices include
software configurable analog multiplexers and bipolar and
unipolar conversion modes as well as on-chip sample-
