made using the MUX0 and MUX1 pins as shown in
Table 1 on page
Although a mux selection is provided to enable the
INA and INB switches simultaneously, signal cur-
rent should not be driven through them in this
mode. The CS3301A mux switches will maintain
good linearity only with minimal signal currents.
2.2.4
A power-down mode is available to shut down the
amplifier when not in use. When enabled, all inter-
nal circuitry is disabled, the analog inputs and out-
puts go high-impedance, and the device enters a
micro-power state. Power down mode is selected
using the PWDN pin, which is active high.

The analog power pins of the CS3301A are speci-
fied to run from bipolar

±
2.5 V power supplies.
When using bipolar power supplies, the analog sig-
nal common mode voltage should be biased to 0 V.
The analog power supplies are recommended to be
bypassed to system ground using 0.1 µF X7R type
capacitors.
The VA- supply is connected to the CMOS sub-
strate and as such must remain the most negative
applied voltage. It is recommended to clamp the
VA- supply to system ground using a reversed bi-
ased Schottky diode to prevent possible damage re-
lated to mis-matched power supply initialization.
2.3.2
The digital voltage across the VD and GND pins is
specified for a +3.3 V power supply. The digital
power supply should be bypassed to system ground
using a 0.01 µF X7R type capacitor.
