Maxim Integrated MAX98306ETD+T, Class D stereo amplifier, 3.7W x 2 @ 3Ω, 2.6V-5.5V supply, -40°C to 85°C, 14-TDFN (3x3mm) exposed pad package.
| Parameter | Value |
|---|---|
| Type | Class D |
| Output type | 2-Channel (Stereo) |
| Mounting | Surface Mount |
| Supply voltage | 2.6V ~ 5.5V |
| Max output power x channels @ load | 3.7W x 2 @ 3Ohm |
| Operating temperature | -40°C ~ 85°C (TA) |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Features | Depop, Differential Inputs, Short-Circuit and Thermal Protection, Shutdown |
| Case | 14-WFDFN Exposed Pad |
It includes depop circuitry to suppress turn-on thumps, differential inputs for noise rejection on long signal traces, and both short-circuit and thermal protection. The shutdown pin lets a microcontroller or GPIO line kill the output for power saving.
Package is 14-TDFN (3x3mm) with exposed pad. The pad is the thermal path to the ground plane.
Product status is Active and ROHS3 compliant.
Yes. The supply voltage range is 2.6V to 5.5V, so a 3.3V rail is well within spec. Output power will be lower than the 3.7W x 2 @ 3Ω rating, which is measured at the top of the supply range.
The MAX98306ETD+T is the Tape & Reel packaged variant of the MAX98306. The die and electrical specs are identical — the suffix denotes the shipping format only.
