Board Layout and Bypassing
Use 1.0FF bypass capacitors from VCC to GND. To maxi-
mize performance, minimize stray inductance by putting
this capacitor close to the VCC pin and reducing trace
lengths. Use 1nF bypass capacitors from REF/INA- to
GND as close as possible to the IC. Do not route noisy
traces near REF/INA-.
Jack Detect
The IC can be used to detect peripheral devices
connected to a circuit using comparator B. This includes
a simple jack-detect scheme for cell phone applica-
tions. Figure 8 shows how the device can be used in
conjunction with an external reference to detect an
accessory ID input. The open-drain output of
the devices allows the output logic level to be con-
trolled independent of the peripheral device’s load,
making interfacing and controlling external devices
as simple as monitoring a few digital inputs on a
microcontroller or codec.
