Stereo Cap-Free Line Driver
Features
General Description
Operating Voltage: 2.3V-4.5V
The APA2174 is a stereo, single supply and cap-free line
Supply Current
driver, which is available in TQFN4x4-20B, TSSOP-16,
- IDD=5mA at VDD=3.3V
Low Shutdown Current
- IDD=1µA at VDD=3.3V
Ground Reference Output
and SOP-14 packages.
The APA2174 is a ground-reference output and doesn’t
need the output capacitors for DC blocking. The advan-
tages of eliminating the output capacitor are saving the
cost, eliminating component height, and improving the
- No Output Capacitor Required (for DC Blocking) low frequency response.
- Save the PCB Space
The external gain setting is recommended using from
- Reduce the BOM Costs
-1V/V to -10V/V. High PSRR provides increased immunity
- Improve the Low Frequency Response
to noise and RF rectification. The independent shutdown
Output Voltage Swing Can Reach 2Vrms/Ch into control of APA2174 is for right channel and left channel.
600at VDD=3.3V
The APA2174 is capable of driving 2Vrms at 3.3V into
High PSRR: 90dB at 217Hz
600load, and provides thermal protection.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
