APA2176/2176A

270mW Stereo Cap-Free Headphone Driver

Features

General Description

The APA2176/2176A is a stereo, fixed gain, and cap-free

headphone driver which is available in TQFN4x4 20-pin,

TQFN3x3 16-pin (APA2176A) or TSSOP-16 package. Dual

supply voltage provides higher efficiency and better power

ripple rejection.

No Output Capacitor Required

Dual Supply Voltage (PV_DD>V_DD)

– V_DD=1.8 ~5.5V

– PV_DD=2.2 ~ 5.5V

Meeting VISTA Requirements

Output Power

The APA2176/2176A is designed with ground-reference

output and no need the output capacitors for DC blocking.

The advantages of eliminating the output capacitor are

saving the cost, PCB’s space, and component height.

The built-in gain setting can minimize the external com-

ponent counts and save the PCB space. High PSRR pro-

vides increased immunity to noise and RF rectification. In

addition to these features, a fast start-up time and small

package size make the APA2176/2176A an ideal choice

for portable multimedia devices.

at 1%THD+N

-200mW, at V_DD=3.3V, PV_DD=5.0V, R_L=16W

-55mW, at V_DD=1.8V, PV_DD=3.0V, R_L=16W

at 10%THD+N

-270mW, at V_DD=3.3V, PV_DD=5.0V, R_L=16W

-70mW, at V_DD=1.8V, PV_DD=3.0V, R_L=16W

Less External Components Required

High PSRR: 80dB at 217Hz

Fast Start-Up Time : 120ms

Short-Circuit and Thermal Protection

Surface-Mount Package

Moreover, the APA2176/2176A is also equipped other

features. For example, at THD+N=1%, it is capable of

driving 200mW at V_DD=3.3V, PV_DD=5.0V into 16W. In

addition, it provides thermal and short circuit protections.
