TA7368PG-R10-R

UTC Unisonic Tech · Audio Power OpAmps · SSOP-10-150mil

TA7368PG-R10-R from UTC Unisonic Tech, in a SSOP-10-150mil. 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 NC unconnected No connection. This pin is not internally bonded on the SSOP-10 package and should be left floating or tied to a convenient net per PCB layout preference.
2 VCC power_in Positive supply voltage input. Typical operating VCC=6V (3V to 9V typical range); absolute maximum 14V. Bypass to GND with a 100µF capacitor near the pin. Typical DC voltage 6.0V at test conditions.
3 NC unconnected No connection. This pin is not internally bonded on the SSOP-10 package and should be left floating.
4 VIN input Audio signal input to the PNP differential pair (via a PNP emitter follower Q1 that allows DC referencing of the source to GND). Input resistance ~27kΩ. DC-coupling is possible; add a series coupling capacitor if brush noise from the volume pot is an issue. Typical DC voltage 0V at no signal.
5 RIPPLE passive Ripple rejection filter terminal. Adding a bypass capacitor (Crip) from this pin to GND improves supply ripple rejection from -25dB to -45dB (fR=100Hz, VR=0.3Vrms). Typical DC voltage 2.40V at no signal.
6 NF passive Negative Feedback terminal. Voltage gain is fixed at Gv=40dB by internal resistors R4 and R5; the gain can be reduced by adding an external Rf per Gv=20log(R5+R4+Rf)/(R4+Rf). Recommend keeping gain ≥28dB. Typical DC voltage 0.62V at no signal.
7 PHASE passive Phase-compensation / oscillation-prevention terminal from the internal amplifier stage. Requires a small-temperature-coefficient capacitor with good frequency characteristics for stable operation. Typical DC voltage 0.64V at no signal.
8 PRE-GND power_in Pre-amplifier (signal) ground return. Kept separate from power ground to minimize output stage current coupling into the low-level pre-amp stage. Typical DC voltage 0V.
9 PW-GND power_in Power (output stage) ground return for the class-AB output transistors. Route with low-impedance traces to the supply return; keep separate from PRE-GND for best noise performance. Typical DC voltage 0V.
10 POUT output Audio power output. Drives loudspeaker load (typ. 4Ω or 8Ω) through a DC-blocking capacitor (e.g., 470µF). Delivers ~500-720mW into 4Ω at VCC=6V, THD=10%, and up to ~1100mW into 8Ω at VCC=9V. Typical DC voltage 2.61V (approx. VCC/2) at no signal.
