CS43L36
Low-Power, High-Performance Audio DAC with Class H Headphone Drivers
System Features
• Integrated fractional-N PLL
• Stereo headphone (HP) output with 114-dB dynamic range — Increases system-clock flexibility for audio processing
— Class H HP amplifier with four-level automatic or
manual supply adjust
— –98-dB THD+N into 30 with 10-mW output power
— 2 x 35 mW output power into 30 with 0.018%
THD+N
• Load detection
— Headphone load detection of 15 or 30
— Line-level load (3 k) with capacitance detection
• Headphone insertion/removal detection with WAKE
• Audio serial port (ASP)
— I2S (two channels) or TDM (up to four channels)
— Reference clock sourced from I2S/TDM bit clock
• Bypassable SRCs for maximum flexibility
• Attenuation, mute, and volume controls for each output
• Integrated power management
— Digital core operates from either an external 1.2-V
supply or LDO from a 1.8-V supply.
— Step-down charge pump improves HP efficiency
— Independent peripheral power-down controls
— Standby operation from VP with all other supplies
powered off
— VP monitor to detect and report brownout conditions
— Slave or Hybrid-Master Mode (bit-clock slave and
LRCK/FSYNC derived from bit clock)
— Supports up to 32-bit audio
— Sample rate support for 8 to 192 kHz
— I2C control with interrupt output
— Low-impedance switching suppresses ground-noise
Applications
• Ultrabooks, tablets, and smartphones
• Digital headsets

CS43L36
CS43L36
General Description
The CS43L36 is a low-power, high dynamic-range, stereo audio DAC with integrated I2S/I2C/TDM interfaces designed for
portable applications. The CS43L36 features support for up to 32-bit audio inputs and includes bypassable SRCs.
The bypassable fractional-N PLL sourced from the ASP SCLK allows for maximum flexibility in any system.
There is independent attenuation on each input along with volume adjustment and mute control.
The CS43L36 is available in 49-ball WLCSP package and a 40-pin QFN package, both supporting an extended
commercial operational temperature range of –40°C to +85°C.
