Overview

  • Four Complete 12-Bit DACs in One IC Package
  • Linearity Error ±1/2LSF
    Tmin - Tmax(AD390K, T)
  • Factory-Trimmed Gain and Offset
  • Buffered Voltage Output
  • Monotonicity Guaranteed Over Full Temperature Range
  • Double-Buffered Data Latches
  • Includes Reference and Buffer
  • Fast Setting: 8µs max to ± 1/2LSB

The AD390 contains four 12-bit high speed voltage-output digital-to-analog converters in a compact 28-pin hybrid package. The design is based on a proprietary latched 12-bit DAC chip which reduces chip count and provides high reliability. The AD390 is ideal for systems requiring digital control of many analog voltages where board space is at a premium. Such applications include automatic test equipment, process controllers, and vector-scan displays.

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
