ISD5216
1. GENERAL DESCRIPTION
The ChipCorder ISD5216 is an 8 to 16 minute Voice and Data Record and Playback system with
integrated Voice band CODEC. The device works on a single 2.7V to 3.3V supply, and has fully
integrated system functions, including: AGC, microphone preamplifier, speaker driver, memory and
CODEC. The CODEC meets the PCM conformance specification of the G.714 recommendation. Its µ-
Law and A-Law compander meets the specification of the ITU-T G.711 recommendation.
