TEA2025L-D16-T from UTC Unisonic Tech, in a DIP-16. 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 | BRIDGE | output | Bridge-mode output providing the reduced CH1 output signal via an internal divider, connected through a capacitor to pin 6 for bridge operation. |
| 2 | OUT.2 | output | Channel 2 power amplifier output, rated for 1.5 A peak output current. |
| 3 | BOOT.2 | passive | Channel 2 bootstrap pin, with a suggested 100uF capacitor to increase output swing. |
| 4 | GND | power_in | Ground pin, connected to ground in the application circuit. |
| 5 | GND | power_in | Ground pin, connected to ground in the application circuit. |
| 6 | FEEDBACK | input | Channel 2 inverting input/feedback pin, where gain is set by the on-chip resistors with external Rf and C1 in series to ground (gain not below 36 dB recommended). |
| 7 | IN.2 (+) | input | Channel 2 non-inverting input, tied to ground in bridge mode. |
| 8 | SVR | passive | Supply voltage rejection decoupling pin, with a 100uF capacitor to ground in the application circuit. |
| 9 | GND (sub) | power_in | Substrate ground pin, connected to ground. |
| 10 | IN.1 (+) | input | Channel 1 non-inverting input, with a PNP input stage allowing the source to be ground-referenced; input impedance is 30 kOhm typical. |
| 11 | FEEDBACK | input | Channel 1 inverting input/feedback pin, where gain is set by the on-chip resistors with external Rf and C1 in series to ground. |
| 12 | GND | power_in | Ground pin, connected to ground in the application circuit. |
| 13 | GND | power_in | Ground pin, connected to ground in the application circuit. |
| 14 | BOOT.1 | passive | Channel 1 bootstrap pin, with a suggested 100uF capacitor to increase output swing. |
| 15 | OUT.1 | output | Channel 1 power amplifier output, rated for 1.5 A peak output current. |
| 16 | +Vs | power_in | Positive supply, operating range 3 V to 12 V with an absolute maximum of 15 V. |
