General Description

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.


Features

  • 4- or 8- channel configurable multiplexer
  • Analog input track/hold function
  • 0V to 5V analog input range with single +5V power supply
  • -5V to +5V analog input voltage range with ±5V supplies
  • Fully tested in unipolar (single +5V supply) and bipolar (dual ±5V supplies) operation
  • Programmable resolution/speed and output data format
  • Ratiometric or Absolute voltage reference operation
  • No zero or full scale adjustment required
  • No missing codes over temperature
  • Easy microprocessor interface
