AD7582:  CMOS 12-Bit Successive Approximation A/D Converter

Product Details


The AD7582 is a medium speed, 4-channel 12-bit CMOS A/D converter which uses the successive approximation technique to provide a conversion time of 100 µs per channel. An auto-zero cycle occurs at the start of each conversion resulting in very low system offset voltages, typically less than 100 µV. The devices is designed for easy microprocessor interface using standard control signals; CS (decoded device address), RD (READ) and WR, (WRITE). The 4-channel multiplexer is controlled via address inputs A0 and A1.

FEATURES and BENEFITS

  • 12-Bit Successive Approximation ADC
  • Four High Impedance Input Channels
  • Analog Input Voltage Range of 0 to +5 V with Positive Reference of +5 V
  • Conversion Time of 100 µs Per Channel
  • No Missed Codes Over Full Temperature Range
  • Low Total Unadjusted Error ±1 LSB max
  • Auto-zero Cycle for Low Offset Voltage
  • Monolithic Construction

The AD7582 is not recommended for new design.
