Stereo Cap-Free Line Driver

Features

General Description

• Operating Voltage: 2.3V-4.5V

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

• Supply Current

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

- I =5mA at V =3.3V

• Low Shutdown Current

- IDD=1µA at VDD=3.3V

• Ground Reference Output

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

- No Output Capacitor Required (for DC Blocking) response.

- Save the PCB Space

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