Stk411210e Datasheet ^new^ -
The STK411-210E is a thick-film hybrid integrated circuit (IC) designed by Sanyo (now part of Panasonic) as a high-performance 2-channel AF power amplifier. This IC is widely recognized for its use in premium audio systems, such as the Sony HCD-GRX90, due to its reliability and low harmonic distortion. Key Technical Specifications
- Output power: RMS power rating into specified loads (e.g., 20–50 W per channel into 8Ω or 4Ω, at THD specified and with a given supply voltage).
- Supply voltage range: maximum and minimum dual-rail voltages (e.g., ±25–±45 V), or single-supply equivalent with specified bridge/tied load conditions.
- Total harmonic distortion (THD): often specified at 1 kHz at a given output power (e.g., 0.1%–1%).
- Frequency response: lower and upper −3 dB points, and a flat band (20 Hz–20 kHz typically).
- Input sensitivity and gain: input volts required for rated output and the amplifier’s voltage gain in dB.
- Signal-to-noise ratio (SNR): measured relative to rated output or A-weighted noise floor.
- Quiescent current and idling dissipation: important for thermal design.
- Output offset and DC characteristics: maximum allowed offset to protect speakers.
- Short-circuit protection and thermal shutdown thresholds: the current/thermal limit behavior.
Note: Some datasheet versions show pins 5 and 9 as bootstrap or feedback pins. Always refer to the exact datasheet revision for your module. The STK411210E is often used with a split feedback network. stk411210e datasheet
