Key Features

  • High-Performance Audio Playback: The AD1861R-J is designed with a combination of bipolar and MOS devices, along with thin-film resistors, to achieve high performance audio playback.
  • Integrated Components: Includes a voltage output amplifier, a DAC, a serial-to-parallel register, and a voltage reference, eliminating the need for external components.
  • Low Distortion: Laser-trimming of the resistors in the R-2R ladder structure reduces linearity error, resulting in low output distortion.
  • Fast Switching Speeds and Low Power Consumption: The CMOS logic gates in the input register and serial-to-parallel converter enable fast switching speeds and low power consumption.
  • Optional Trim for Super-Linear Performance: Allows for enhanced performance through optional trimming.
  • Pin-Compatible Packages: Available in 16-pin plastic DIP and SOIC packages, pin-compatible with AD1856 and AD1860 audio DACs.

Applications

  • High-End Compact Disc Players: Ideal for high-quality audio playback in compact disc players.
  • Digital Audio Amplifiers: Used in digital audio amplifiers for superior sound quality.
  • DAT Recorders and Players: Suitable for digital audio tape recorders and players.
  • Synthesizers and Keyboards: Employed in musical instruments for high-fidelity audio output.
