TPA6203A1DGNR from Texas Instruments, in a MSOP-8-EP. 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 | SHUTDOWN | input | Active-low shutdown control terminal; supply current drops to <0.9 µA when SHUTDOWN ≤ 0.8 V. |
| 2 | BYPASS | output | Mid-supply voltage reference output (VDD/2); connect 0.22 µF bypass capacitor to ground for improved PSRR. |
| 3 | IN+ | input | Positive differential input; common-mode voltage range 0.5 V to (VDD - 0.8 V) with 2 MΩ input impedance. |
| 4 | IN- | input | Negative differential input; common-mode voltage range 0.5 V to (VDD - 0.8 V) with 2 MΩ input impedance. |
| 5 | VO+ | output | Positive bridged-tied-load (BTL) output; 1.25 W maximum into 8 Ω at 5 V (1% THD+N). |
| 6 | VDD | power_in | Power supply input; operating voltage range 2.5 V to 5.5 V with 1.7 mA typical quiescent current at no load. |
| 7 | GND | power_in | Ground connection; high-current return path for output stage return current. |
| 8 | VO- | output | Negative bridged-tied-load (BTL) output; 1.25 W maximum into 8 Ω at 5 V (1% THD+N). |
| 9 | Thermal Pad | power_in | Exposed thermal pad; must be soldered to ground plane for thermal and mechanical performance. |
