XL567

XINLUDA · Audio Interface ICs · SOP-8

XL567 from XINLUDA, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OF_CAP passive Output filter capacitor pin. External capacitor forms a post-detection low-pass filter with an internal 4.7 kΩ resistor; recommended value is at least 2× the loop filter capacitor (C3 ≥ 2·C2).
2 LF_CAP passive Loop filter capacitor pin (low-pass filter of the internal PLL). Capacitance C2 together with fo sets the detection bandwidth (see Table 7-2); a typical value is 1 µF.
3 IN input Device signal input. Input resistance is typically 20 kΩ; smallest detectable input voltage ≈ 20 mVrms, maximum input voltage level ±8.5 V. Detects tones from 1 Hz up to 500 kHz.
4 VCC power_in Positive supply voltage pin. Recommended operating range 3.5 V to 8.5 V (absolute max 9 V). Requires a decoupling capacitor placed as close as possible to the pin.
5 T_RES passive Timing resistor connection pin. External resistor R1 together with C1 on T_CAP sets the VCO free-running (center) frequency: fo ≈ 1 / (1.1 × R1 × C1).
6 T_CAP passive Timing capacitor connection pin. External capacitor C1 together with R1 on T_RES sets the VCO free-running (center) frequency; a 0.1 µF capacitor is typical.
7 GND power_in Circuit ground reference for the device.
8 OUT output Device output. Open-collector NPN power transistor that switches to ground when an in-band tone is detected; requires an external pull-up load resistor. Sink capability up to 100 mA (max absolute rating V8 = 15 V).
