FOUR CHANNEL HD AUDIO CODECS WITH DUAL CAPLESS HEADPHONE AMPLIFIERS
ESD: The 92HD66B is an ESD (electrostatic discharge) sensitive device. The human body and test equipment can
accumulate and discharge electrostatic charges up to 4000 Volts without detection. Even though the 92HD66B implements
internal ESD protection circuitry, proper ESD precautions should be followed to avoid damaging the functionality or
performance.
3.3. 92HD66B Analog Performance Characteristics
• 5V AVDD
(T_ambient = 25 ºC, AVdd = 4.75V (4.5-5.25V), DVdd = 3.3V ± 5% or 1.8V± 10%, AVss=DVss=0V; 20Hz to 20KHz swept sinusoidal
input; Sample Frequency = 48 kHz; 0dB FS = 1Vrms for AVdd = 4.75V, 10KΩ//50pF load, Testbench Characterization BW: 20 Hz –
20 kHz, 0 dB settings on all gain stages)
• 3.3V AVDD
(T_ambient = 25 ºC, AVdd = 3.3V, DVdd = 3.3V ± 5% or 1.8V ± 10%, AVss=DVss=0V; 20Hz to 20KHz swept sinusoidal input; Sample
Frequency = 48 kHz; 0dB FS = 0.707Vrms for AVdd = 3.3V, 10KΩ//50pF load, Testbench Characterization BW: 20 Hz – 20 kHz, 0 dB
settings on all gain stages)
