General Description
The BL6311B is a 3-W high efficiency filter-free class-D audio power amplifier in a wafer
chip scale package (WCSP) that requires only three external components.
Features like 88% efficiency, −75dB PSRR, and improved RF-rectification immunity make
the BL6311B ideal for cellular handsets. In cellular handsets, the earpiece, speaker phone, and
melody ringer can each be driven by the BL6311B.

(1) CI should have a tolerance of ±10% or better to reduce impedance mismatch.
(2) Use 1% tolerance resistors or better to keep the performance optimized, and place the
RI close to the device to limit noise injection on the high-impedance nodes.
Input Resistors (RI) & Capacitors (CI)
The input resistors (RI) set the total voltage gain of the amplifier according to Eq1
Gain = 2 ×150k

Eq1
The input resistor matching directly affects the CMRR, PSRR, and the second harmonic
distortion cancellation.
If a differential signal source is used, and the signal is biased from 0.5V ~ VDD-0.8V (shown
in Figure2), the input capacitor (CI) is not required.
If the input signal is not biased within the recommended common-mode input range in
differential input application (shown in Figure3), or in a single-ended input application (shown in
Figure4), the input coupling capacitors are required.
If the input coupling capacitors are used, the RI and CI form a high-pass filter (HPF). The
corner frequency (fC) of the HPF can be calculated by Eq2
fC

Eq2
Decoupling Capacitor (CS)
A good low equivalent-series-resistance (ESR) ceramic capacitor (CS), used as power supply
decoupling capacitor (CS), is required for high power supply rejection (PSRR), high efficiency and
low total harmonic distortion (THD). Typically CS is 2 2µF, placed as close as possible to the
device VDD pin.
