DESCRIPTION
The HT560 is a stereo Class D audio amplifier with
an I2S input serial port. It supports a variety of audio
clock configurations via two speed modes.
0.05% (PVDD=12V, RL=4Ω, Po=1W)
0.02% (PVDD=24V, RL=8Ω, Po=1W)
- Noise
75uV (Gain = 25.2dB, A weighted)
- Efficiency
91 % (PVDD=12V, RL=4Ω, Po=10W)
The outputs of the HT560 can be configured to
drive two speakers in stereo BTL mode or mono
PBTL mode.
・Audio I/O Configuration
The HT560 also includes hardware and I2C control
modes, integrated digital clipper, AGC, several gain
options, and a wide power supply operating range
to enable use in a multitude of applications.
- Single Stereo I2S Input
- BTL or PBTL output
- 32, 44.1, 48, 88.2, 96kHz Sample Rates
・General Operational Features
- Selectable Hardware or I2C Control mode
- Integrated Digital Output Clipper and AGC
- Integrated Thermal Foldback Function
- Programmable I2C Address (110110x[R/W])
- Adjustable Switching Frequency for Class D
An optimal mix of thermal performance and device
cost is provided in the 110-mΩ RDS(ON) of the output
MOSFETs. Additionally, a thermally enhanced
36-Pin QFN provides excellent operation in the
elevated ambient temperatures found in modern
consumer electronic devices.
