General Description

The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation.

The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter. In addition, the A/D's reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution.

The A/Ds are designed to operate from the control bus of a wide variety of microprocessors. TRI-STATE output latches that directly drive the data bus permit the A/Ds to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.

Features

  • Easy interface to all microprocessors
  • Operates ratiometrically or with 5 VDC voltage reference
  • No zero or full-scale adjust required
  • 4-channel or 8-channel multiplexer with address logic
  • Internal clock
  • 0V to 5V input range with single 5V power supply
  • 0.3[Prime] standard width 20-pin or 24-pin DIP
  • 28 Pin Molded Chip Carrier Package
