Talking Back The HT8656 is a single chip CMOS LSI for talking back applications using an ADM algorithm. Functions of the IC consist of recording/playing as well as auto power off. It starts recording when a sound input is detected, and stops to play back when silence lasts 0.5 seconds during recording. The auto power off function is activated once a REC/PLAY cycle has been implemented 64 times or an interval of silence exceeds 2 minutes. The HT8656 provides a recording capacity of 2 seconds for DRAM of 64K and 8 seconds for DRAM of 256K at a 32Kb sampling rate and double recording capacity at a 16Kb sampling rate. A higher sampling rate will result in sounds of better quality but sacrifice the recording ... |

The HT8658 and HT8659 have almost the same functions apart from the reset time. The reset time of the HT8658 has to be over 4 seconds but of the HT8659 over 2 seconds. Blocks within each chip include a DRAM interface circuit, signal amplifier, 8 bit ADC and internal low pass filter. Encoded data are stored in external DRAMs and played back after the PLYB pin be triggered. Each IC provides four kinds of sampling rate to be selected, namely 32K/22K/16K/11K bps (bits per second). A higher sampling rate results in sounds of better quality but sacrifices the recordin... |

Talking Back The HT8665 is a single chip CMOS LSI using an ADM algorithm. It is designed for applications on talking back with an echo effect. Functions of the IC consist of recording/playing and auto power off in addition to an echo effect. The IC starts recording when a sound input is detected, and stops to play back when silence lasts 0.5 seconds during recording. The auto power off function is activated once a REC/PLAY cycle has been implemented 64 times or an interval of silence exceeds 2 minutes. The HT8665 provides a recording capacity of 2 seconds at a 32K bps sampling rate for DRAM of 64K (8 seconds for DRAM of 256K) and 4 seconds at a 16K bps sampling rate (16 seconds for DRAM of 256Kb).
