ADADC85:  Fast, Complete 12-Bit A/D Converters

Product Details

The ADADC85 devices are highspeed, low-cost 10- and 12-bit successive approximation analog-to-digital converters that include internal clock, reference and comparator. Its hybrid IC design utilizes MSI digital and linear monolithic chips in conjunction with a 12-bit monolithic DAC to provide modular performance and versatility with IC size, price and reliability.


  • Complete 12-bit A/D converter with reference and clock
  • Fast successive approximation conversion:
    10 µs or 5 µs
  • Buried Zener reference for long-term stability
    and low Gain TC: 10 ppm/°C
  • Max nonlinearity: < ±0.012%
  • Low power: 880 mW typ
  • chip count—high reliability
  • Industry-standard pinout
  • Z models for ±12 V operation available
  • MIL-STD-883B processing available
  • Negative true parallel logic outputs
  • Short cycle capability
  • Precision +6.3 V reference for
    external applications

Of Note ...

The Serial Output function is no longer supported on this product after a date code of 9623.
