7 / 9 page 7 Specification ...... Specification ...... Specification ...... Specification ...... Specification ...... Notes Notes Notes Notes Notes 1. V DD = 3.3V 2. V DD = 5.0V 3. With adherence to Signal-to-Voice and Signal-to Noise specifications. 4. With Input Amp gain setting: 15.5dB MIN/18.0dBMAX. 5. Common Mode SPM and balanced voice signal. 6. Immune to false responses. 7. Immune to false de-responses 8. With SPM and voice signal amplitudes balanced; To avoid false de-responses due to saturation, the peak-to-peak voice+noise level at the output of the Input Amp (12/16kHz Filter Input) should be no greater than the dynamic range of the device. 9. Maximum voice frequencies = 3.4kHz 10. Response, De-Response and Power-up Response Timing. SIGNAL INPUT TONE NOTONE RESPONSE DELAY DERESPONSE DELAY SIGNAL INPUT ......
