TPA6011A4
SLOS392A – FEBRUARY 2002 – REVISED JULY 2004
APPLICATION INFORMATION (continued)
A.
A 0.1-F ceramic capacitor should be placed as close as possible to the IC. For filtering lower-frequency noise
signals, a larger electrolytic capacitor of 10 F or greater should be placed near the audio power amplifier.
Figure 29. Typical TPA6011A4 Application Circuit Using Differential Inputs
The ability of the TPA6011A4 to easily switch between BTL and SE modes is one of its most important cost
saving features. This feature eliminates the requirement for an additional headphone amplifier in applications
where internal stereo speakers are driven in BTL mode but external headphone or speakers must be
accommodated. Internal to the TPA6011A4, two separate amplifiers drive OUT+ and OUT-. The SE/BTL input
controls the operation of the follower amplifier that drives LOUT- and ROUT-. When SE/BTL is held low, the
amplifier is on and the TPA6011A4 is in the BTL mode. When SE/BTL is held high, the OUT- amplifiers are in a
high output impedance state, which configures the TPA6011A4 as an SE driver from LOUT+ and ROUT+. IDD is
reduced by approximately one-third in SE mode. Control of the SE/BTL input can be from a logic-level CMOS
source or, more typically, from a resistor divider network as shown in Figure 30. The trip level for the SE/BTL
input can be found in the recommended operating conditions table.
