Model      Voltage range   Quiescent current       Speed length                 Sampling range    Playback mode    Encapsulation

NV020C  2V~4.5V              2uA                               20 seconds(6K)       6K~44.1K               PWM/DAC              SOP8/DIP8

NV040C  2V~4.5V              2uA                               40 seconds (6K)      6K~44.1K               PWM/DAC              SOP8

NV080C  2V~4.5V              2uA                               80 seconds (6K)      6K~44.1K               PWM/DAC              SOP8/DIP8

NV180C  2V~4.5V              2uA                               180 seconds (6K)    6K~44.1K               PWM/DAC              SOP28

Note: speech lengths all of 6K sample rate, sample rate generally applied is greater than 8K, so the speech length is for reference only.
