HT2411ARZ

HTCSEMI · Audio Power OpAmps · SOP-8

HT2411ARZ from HTCSEMI, in a SOP-8. 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 VCC power_in Power supply pin with a DC supply voltage absolute maximum rating of 36 V and a supply initiation voltage (VSI) of 17 to 21 V.
2 RSL input Resistor select pin used on the HT2411 to change the supply initiation current (ISI) through an external resistor, shown with RSL=6.2k, 10k and 15k.
3 LFI input Low frequency oscillator input, where the low tone frequency is set by R1 and C1 with fL = 1/(1.359×R1×C1).
4 LFO output Low frequency oscillator output of the low tone generator.
5 GND power_in Ground pin; all voltage values in the datasheet are stated with respect to the anode terminal.
6 HFO output High frequency oscillator output, where fH1 = 1/(1.518×R2×C2) and fH2 = 1.214×fH1.
7 HFI input High frequency oscillator input, where the high tone frequency is set by R2 and C2.
8 OUT output Output amplifier pin with a minimum high output voltage (VOH) of 17.7 V at IOH=15mA.
