CA3338A - CMOS Video Speed/ 8-Bit/ 50 MSPS/ R2R D/A Converters

General Description

The CA3338 family are CMOS/SOS high speed R2R voltage output digital-to-analog converters.

They can operate from a single +5V supply, at video speeds, and can produce “rail-to-rail” output swings.

Key Features

  • CMOS/SOS Low Power.
  • R2R Output, Segmented for Low “Glitch”.
  • CMOS/TTL Compatible Inputs.
  • Fast Settling: (Typ) to 1/2 LSB.
  • . 20ns.
  • Feedthrough Latch for Clocked or Unclocked Use.
  • Accuracy (Typ).
  • ±0.5 LSB.
  • Data Complement Control.
  • High Update Rate (Typ).
  • 50MHz.
  • Unipolar or Bipolar Operation.

338 family are CMOS/SOS high speed R2R voltage output digital-to-analog converters. They can operate from a single +5V supply, at video speeds, and can produce “rail-to-rail” output swings. Internal level shifters and a pin for an optional second supply provide for an output range below digital ground. The data complement control allows the inversion of input data while the latch enable control provides either feedthrough or latched operation. Both ends of the R2R ladder network are available externally and may be modulated for gain or offset adjustments. In addition, “glitch” energy has been kept very low by segmenting an
