LM4675SDX

Texas Instruments · Audio Power OpAmps · WSON-8-EP(3x3)

LM4675SDX from Texas Instruments, in a WSON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN+ input Non-inverting differential audio input, with gain set as AV = 2 * 150kΩ / Ri by the external input resistor.
2 IN- input Inverting differential audio input, with gain set as AV = 2 * 150kΩ / Ri by the external input resistor.
3 VDD power_in Supply voltage pin, operating range 2.4V to 5.5V, to be bypassed with a 4.7µF capacitor placed close to the device.
4 SHDN input Active-low shutdown input: a logic low (GND) or floating pin enters shutdown, with 1.4V minimum for high and 0.4V maximum for low, and an internal 300kΩ resistor to GND.
5 VO1 output Filterless spread-spectrum PWM output 1 to the speaker, switching between VDD and GND at 300kHz ±30%.
6 GND power_in Ground pin, the reference for all voltages (absolute maximum input voltage is GND - 0.3V).
7 PVDD power_in Power-stage supply pin, operating range 2.4V to 5.5V, tied to the same supply as VDD.
8 VO2 output Filterless spread-spectrum PWM output 2 to the speaker, switching between VDD and GND at 300kHz ±30%.
9 EP passive Exposed thermal pad that must be soldered to the printed circuit board for thermal and mechanical performance.
