CR6831T Datasheet Digital Echo/surround Processor Ic

Manufacturer: Chip-Rail

Overview: .. CR6831T Digital Echo/Surround Processor IC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CR6831T is an IC developed for producing echo effects added to voice signals picked up by microphone for karaoke applications.

The IC has the largest memory among the digital delay series.

As it’s design is aimed at high performance, it is best suited to provide radio cassette tape recorders and miniature unit audio system with quality echo function.

Key Features

  • Built-in input / output filters, A-D and D-A converters, and memory realize a delay system with only a single chip.
  • Capable of composing low-noise and low-distortion delay system at low cost by ADM system (No=-92dB typ, THD=0.5% typ).
  • Control mode selections available from 2 kinds: easy mode using parallel data and microcomputer mode using serial data.
  • Sleep mode can be selected to stop IC functions.
  • Built-in automatic reset circuit Outline Outline 24P4.
