TDA1564 Overview
TDA1564 The TDA1564 is a monolithic power amplifier in a 17-lead single-in-line (SIL) plastic power package. It contains two identical 25 W amplifiers. The dissipation is minimized by switching from SE to BTL mode, only when a higher output voltage swing is needed.
TDA1564 Key Features
- Low dissipation due to switching from Single-Ended (SE) to Bridge-Tied Load (BTL) mode
- Differential inputs with high mon Mode Rejection Ratio (CMRR)
- Mute/standby/operating (mode select pin)
- Load dump protection circuit
- Short-circuit safe to ground, to supply voltage and across load
- Loudspeaker protection circuit
- Offset detection for each channel
- Device switches to single-ended operation at excessive junction temperatures
- Thermal protection at high junction temperature (170°C)
- Clip detection at THD = 2.5 %
