Simplified Application Circuit

The APA2175 is a stereo, fixed gain, single supply, and

cap-free line driver, which is available in TQFN4x4-20B

and TSSOP-16 packages.

The APA2175 is ground-reference output, and no need

the output capacitors for DC blocking. The advantages of

eliminating the output capacitor are saving the cost, elimi-

nating component height, and improving the low frequency

response.

The internal fixed gain setting (-1.5V/V) can minimize the

external component counts and save the PCB space.

High PSRR provides increased immunity to noise and

RF rectification. The independent shutdown control of

APA2175 is for right channel and left channel.

The APA2175 is capable of driving 2Vrms at 3.3V into

600

Ω load, and provides thermal protection.
