The SGM4917AYTQ16G/TR is a capless stereo headphone amplifier by SG Micro Corp, suitable for portable devices. It operates from a single supply voltage ranging from 2.7V to 5.5V.
This amplifier delivers 80mW per channel into a 32Ω load from a 5V supply with a total harmonic distortion plus noise (THD+N) of 0.1%. It achieves a low THD+N of 0.02% at 1kHz. The device features a high power supply rejection ratio (PSRR) of -78dB at 217Hz, enabling operation from noisy digital supplies without additional regulators.
Key features include a capless design that eliminates output DC-blocking capacitors, reducing component count and height. It offers built-in shutdown control for pop/click-free operation, short-circuit protection, and thermal-overload protection. The SGM4917A variant allows for adjustable gain via external feedback resistors, while the SGM4917B has a fixed -2V/V gain.
The SGM4917AYTQ16G/TR is available in a Green TQFN-3x3-16L package and operates within an ambient temperature range of -40°C to +85°C. It is supplied on tape and reel with 3000 units per reel.
The supply voltage range is 2.7V to 5.5V.
It provides 80mW per channel into a 32Ω load from a 5V power supply at THD+N = 0.1%.
The typical THD+N is 0.02% at 1kHz.
The operating temperature range is -40°C to +85°C.
It is available in a TQFN-3x3-16L package.
The device is RoHS3 Compliant.
The Moisture Sensitivity Level is 1 Unlimited.
