TS4990IDT from STMicroelectronics, in a SO-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 | STBY | input | Active-low standby control; the datasheet states that the externally controlled standby mode reduces the supply current to less than 10 nA. |
| 2 | BYPASS | passive | Bypass node for half-supply filtering, decoupled by the bypass capacitor Cb as described in the typical application. |
| 3 | VIN+ | power_in | Non-inverting input, used in the differential-input BTL configuration where R1 and R2 should be matched at 1% max for best differential performance. |
| 4 | VIN- | power_in | Inverting input whose gain-setting resistor Rin, together with Rfeed, sets the closed-loop gain AV = 2 x (Rfeed / Rin) in BTL configuration. |
| 5 | VOUT1 | output | BTL output 1 driving the speaker; the device delivers 1.2 W into 8 Ω at VCC = 5 V with THD = 1%. |
| 6 | VCC | power_in | Power supply pin; the operating range is VCC = 2.2 V to 5.5 V. |
| 7 | GND | power_in | Ground pin; on the DFN8 package the exposed pad is electrically connected to this pin. |
| 8 | VOUT2 | output | BTL output 2 driving the speaker, in bridge configuration with VOUT1. |
