× 2.2 W BTL audio amplifier
14.4 Single-ended application
Tamb = 25 °C; VCC = 7.5 V; f = 1 kHz; RL =8 Ω; Gv = 20 dB; audio band-pass 20 Hz to
20 kHz.
The single-ended application diagram is shown in Figure 15.
If the BTL/SE pin is to ground, the positive outputs (OUTL+, OUTR+) will be in mute
condition with a DC level of 0.5VCC. When a headphone is used (RL >25 Ω) the SE
headphone application can be used without coupling capacitors by placing the load
between negative output and one of the positive outputs (for example, pin 1) as the
common pin.
Increasing the value of the tantalum or electrolytic capacitor C3 will result in a better
channel separation. Because the positive output is not designed for high output current
(2
× I
O) at the load impedance (< 16 Ω), the SE application with output capacitors
connected to ground is advised. The capacitor value of C4/C5 in combination with the
load impedance determines the low frequency behavior. The total harmonic
distortion-plus-noise as a function of frequency was measured with a low-pass filter of
80 kHz. The value of the capacitor C3 influences the behavior of the PSRR at low
frequencies; increasing the value of C3 increases the performance of PSRR.
Pins 8, 9, 18 and 19 connected to ground.
