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
- Reduce the BOM Costs
external component counts and save the PCB space.
- Improve the Low Frequency Response
High PSRR provides increased immunity to noise and
