APA2176 - ANPEC

APA2176 270mW Stereo Cap-Free Headphone Driver

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. The APA2176/2176A is designed with ground-reference output and no need the output capacitors for DC blocking.
