ADC10154,ADC10158 ADC10154/ADC10158 10-Bit Plus Sign 4 Вµs ADCs with 4-or 8-Channel MUX,
Track/Hold and Reference Literature Number: SNAS077A ADC10154/ADC10158
10-Bit Plus Sign 4 Вµs ADCs with 4-or 8-Channel MUX,
Track/Hold and Reference
General Description Features The ADC10154 and ADC10158 are CMOS 10-bit plus sign
successive approximation A/D converters with versatile analog input multiplexers, track/hold function and a 2.5V
band-gap reference. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential
or pseudo-differential modes of operation.
The input track/hold is implemented using a capacitive array
and sampled-data comparator.
Resolution can be programmed to be 8-bit, 8-bit plus sign,
10-bit or 10-bit plus sign. Lower-resolution conversions can
be performed faster.
The variable resolution output data word is read in two bytes,
and can be formatted left justified or right justified, high byte
first. n 4-or 8-channel configurable multiplexer

supplies
n Fully tested in unipolar (single +5V supply) and bipolar
(dual В± 5V supplies) operatio Programmable resolution/speed and output data format
n Ratiometric or Absolute voltage reference operatio No zero or full scale adjustment required …
