Functional Description
Figure 4. Micro-USB Application
Application Guidelines
Device Placement – Minimize to USB port & USB TX.
PIN 1, 2, 9, 10 – Minimize and match trace lengths for
USB compliance.
PIN 3, 4 – Suggest 0.1Fcapacitor as close to the
device as possible for DC-blocking and setting low-
frequency response of audio amplifier. The input
capacitors combine with the input impedance of the
amplifiers to form a high-pass filter. Equation 1 can be
used to calculate the -3dB cut-off frequency of the high-
pass filter for the given input capacitor value and the
FSA2000 input impedance.

It is desirable to be below the 20Hz audio range.
Users have flexibility to adjust capacitor for audio
performance in the system design. Equation 2 shows the
cut-off frequency of the recommended guidelines.
PIN 5 – Use standard decoupling devices, 0.1F & 1F
capacitors; as close to the device as possible.
PIN 8 – Minimize ground trace length between headphone
connector and device; minimize ground path resistance.
PIN 12 – Suggested 0.1Fcapacitor to GND for filtering; as
close to the device as possible.
PIN13, 14 – Use low-ESR (equivalent series resistance)
ceramic capacitors for lowest charge pump impedance,
which provides maximum output power of the audio
amplifiers. Recommended to place the components as close
as possible to the device.
PIN15, 16 - The charge pump has been optimized for low-
ESR ceramic capacitors for the flying capacitor between CP
and CM, along with the output capacitors on V+, CPO, and
V-. Optimized values for these capacitors are in Figure 4.
