I2C Programmable-Gain Amplifier
for Audio Applications

_____________________________________________________________________
Note 1:
All voltages are referenced to ground. Currents entering the IC are specified positive, and currents exiting the IC are negative.
Note 2:
Standby supply current specified with SDA = SCL = VCC, the output disconnected, and A0, A1, and A2 driven to within
100mV of VCC or GND.
Note 3:
Input resistance during mute and power-down is approximately one-half of the active-mode resistance.
Note 4:
Each output is capable of driving a 100nF capacitive load to ground using an external 10Ω series resistor. However, output
capacitance should be minimal for optimal distortion performance.
Note 5:
Guaranteed by design.
Note 6:
This is the time it takes for the output to become active after exiting standby mode.
Note 7:
I2C interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with I2C standard-
mode timing.
Note 8:
CB = total capacitance of one bus line in picofarads.
Note 9:
The current specified is the sum of VCC and AVCC supply currents.
Note 10: Gain accuracy specified assuming the output impedance of signal source driving of the DS4420 is ≤ 2.5kΩ.
