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
