CS42L52-CNZ 概要
What is an audio CODEC? An audio CODEC (coder-decoder) is a mixed-signal IC that converts analog audio signals to digital (ADC path) and digital audio streams back to analog (DAC path), providing the bridge between microphones/speakers and a digital signal processor or application processor. Low-power CODECs sit in the broader power-management IC family and target portable, battery-powered audio applications where quiescent current, dynamic range, and integration directly impact playback time and listening quality.
The CS42L52 integrates a flexible stereo analog input architecture with a 4:1 input mux, two headphone amplifiers capable of 44 mW per channel into 32 ohm loads, and a high-efficiency Class D speaker amplifier. Power consumption is 13 mW at 1.8 V in playback mode. The serial audio interface accepts standard I2S, left-justified, and right-justified formats. An on-chip PLL derives the internal audio clocks from a range of reference frequencies, simplifying system clocking.
Typical applications include portable media players, smartphones, tablets, USB audio headsets, portable gaming devices, voice recorders, and Bluetooth/wireless audio docking stations. The CS42L52 suits any battery-powered stereo audio product where board area and power consumption are tightly constrained but high dynamic range and headphone or speaker drive capability cannot be compromised.
When designing with this part, route analog inputs and outputs symmetrically, place decoupling capacitors close to each supply pin, and connect the exposed pad to a low-impedance ground plane for thermal dissipation and noise rejection. Per the CS42L52 datasheet, careful ground partitioning between analog and digital domains is required to achieve the rated 98 dB dynamic range.

主な用途
CS42L52-CNZ の用途: 6 件s: Portable Media Players, USB Audio Headsets, Tablet Computers, Portable Gaming Devices, Bluetooth/Wireless Audio Docks, Voice Recorders and Dictation Devices.
Portable Media Players
The CS42L52-CNZ is purpose-built for portable media players (PMPs) where 98 dB dynamic range and 1 W per channel Class D speaker output matter on battery power. The 13 mW playback consumption at 1.8 V extends battery life versus discrete audio chains, and the 6x6 mm QFN-EP package fits inside slim PMP form factors. The headphone amp drives 32 ohm earphones directly without external buffer. The 4:1 analog input mux allows line-in, microphone, and FM-radio sources to share a single ADC path. For PMP designs, the chip pairs naturally with a host application processor over I2S and can coexist with a CP2102N USB bridge for file transfer.
おすすめ
USB Audio Headsets
USB audio headsets benefit from the CS42L52-CNZ integration of stereo ADC, stereo DAC, headphone amplifier, and microphone preamp on a single chip. The I2S interface links to a USB audio bridge such as CP2102N-A02-GQFN28, while the 44 mW per channel headphone output drives 32 ohm earphones comfortably. Per the Cirrus Logic datasheet, the 8 kHz to 96 kHz sample rate range supports full-bandwidth 48 kHz USB audio. The 1.8 V single-supply operation simplifies power tree design and extends talk time on Li-ion batteries.
おすすめ
Tablet Computers
Tablet computers require stereo audio playback with both headphone and loudspeaker drive, and the CS42L52-CNZ covers both paths with integrated amplifiers. The 1 W per channel Class D output drives tablet loudspeakers efficiently, and the 44 mW headphone amp drives earphones without external buffer. The 40-QFN-EP (6x6) footprint fits in the dense tablet PCB, and the I2S interface connects to the application processor audio port. Per the Cirrus Logic datasheet, the 98 dB dynamic range supports Hi-Fi music playback.
おすすめ
Portable Gaming Devices
Portable gaming consoles need low-latency, low-power stereo audio with headphone output for late-night play, and the CS42L52-CNZ delivers both from a 1.8 V supply. The integrated Class D amplifier drives small game-console speakers at 1 W per channel, and the headphone amp supports gaming headsets. Per the Cirrus Logic datasheet, the I2S serial interface supports standard audio sample rates used by portable gaming platforms. The 6x6 mm QFN-EP package fits within compact handheld enclosures.
おすすめ
Bluetooth/Wireless Audio Docks
Bluetooth and wireless audio docks need a high-quality stereo DAC with both line-driver and headphone outputs, and the CS42L52-CNZ provides this on a single chip. The 98 dB dynamic range preserves audio quality through the DAC-to-speaker chain, and the 1 W per channel Class D output drives dock speakers. The I2S interface accepts digital audio from a Bluetooth SoC, and the 4:1 analog input mux supports auxiliary line-in sources. The 6x6 mm QFN-EP package is well-suited for compact dock enclosures.
おすすめ
Voice Recorders and Dictation Devices
Voice recorders and dictation devices benefit from the CS42L52-CNZ integrated stereo ADC with 4:1 analog input mux, allowing microphone, line-in, and reference inputs to share one chip. The 98 dB dynamic range (A-weighted) preserves voice clarity for transcription and playback. Per the Cirrus Logic datasheet, the 13 mW playback consumption extends battery life for portable recorders. The I2S interface streams to a host MCU or DSP for audio encoding, and the 6x6 mm QFN-EP package fits handheld enclosures.

主な差別化要因

設計ノート
Solder the CS42L52-CNZ exposed thermal pad to a low-impedance ground plane with multiple thermal vias for heat spreading. The exposed pad is the primary thermal dissipation path for the Class D amplifier - without proper soldering, junction temperature may rise during sustained Class D playback. Use a 0.1 uF decoupling capacitor close to each analog supply pin and a 10 uF bulk capacitor on the main supply rail. Keep analog input and output traces short and symmetric to minimize distortion.
Per the Cirrus Logic datasheet, partition the PCB ground plane into analog and digital domains to achieve the rated 98 dB dynamic range. Place the CS42L52-CNZ at the boundary between the analog and digital sections with the exposed pad bridging both grounds at a single point. Route the I2S data, bit clock, and word clock traces together with matched lengths to avoid timing skew. Keep the microphone bias trace short and routed away from switching power and Class D output traces to prevent noise coupling into the microphone ADC path.
The CS42L52-CNZ operates from a single 1.8 V to 3.3 V supply; for portable battery applications, derive this rail from a low-ripple LDO rather than directly from a switching DC-DC converter to avoid audible noise injection into the audio path. The Class D amplifier can draw up to 1 W per channel from the supply during peak playback - verify the upstream regulator or battery can source this peak current without voltage droop. Add bulk capacitance at the IC supply pin to handle Class D inrush.
