Figure 4. Application with Cirrus Logic Interface
Bypass the VY, VX, and 12IN_ inputs with ceramic 0.1µF
capacitors. Bypass the VCC_ and VPP_ outputs with a
0.1µF capacitor for noise reduction and ESD protection.
Apply power to the VL input before any of the switch
inputs. If VX, VY, or 12IN receive power before VL rises
above 2.8V, the supply current may be artificially high
(about 5mA). When the voltage on VL is greater than
2.8V, the part consumes its specified 24µA. To avoid
power sequencing, diode-OR VX and VY to VL through
a 1kΩ resistor (Figure 3). Take care not to allow VL to
drop below the 2.8V maximum undervoltage lockout
threshold.
