CX20671 pdf datasheet

Description :

Conexant’s CX20671 HD Audio codec SoC is a low-power,102 dB SNR, highperformance audio codec with integrated 2-WRMS (per channel) stereo speaker amplifier with Spread Spectrum EMI dispersion technology. Two independent pairs of DACs and three independent pairs of ADCs support Multi-Streaming and Real Time Communications applications. The audio fidelity of the device exceeds Microsoft WLP 4.0 Desktop and Notebook Premium Logo requirements. Additionally, the device achieves a high level of integration by featuring an integrated 5 V to 3.3 V Low-dropout (LDO) voltage regulator that guarantees high performance analog audio performance without incurring external BOM, and an integrated 3.3 V to 1.8 V low-dropout voltage regulator used to power internal digital blocks. […]

Features :

1. 24-bit, two pairs of independent DACs and three pairs of independent ADCs

2. ProCoustic headphone driver, which delivers 50 mW into 32 Ω load with no pop, eliminating the need for an external amplifier and DC-blocking capacitors

3. Integrated 5 V to 3.3 V low-dropout voltage regulator for improved audio performance, eliminating need for external regulator or power transistor

4. Integrated 3.3 V to 1.8 V low-dropout voltage regulator, used to power digital blocks

5. Integrated 2 WRMS (per channel) class-D stereo speaker amplifier with Spread Spectrum and 10-kV ESD withstand capability

Description :

The TC8002D is a Class-AB audio power amplifier. It is capable of delivering 2.0 watts of
continuous average power to an 4Ω BTL load with less than 10% distortion (THD+N) from a
5VDC power supply, or 1.5 watts continuous average power to an 8 Ω BTL load with less than
1% distortion.

The 8002 is designed specifically to provide high quality output power with a minimal
amount of external components. It does not require output coupling capacitors or bootstrap
capacitors. […]

Features :

1. Improved PSRR at 217 Hz & 1 KHz 60 dB
2. Power output at 5.0V, 10% THD+N, 4Ω 2.0 W (typ.)
3. Power output at 5.0V, 1% THD+N, 8Ω 1.5 W (typ.)
4. 2.2V – 5.5V operation
5. Improved circuitry eliminates pop-click noise during turn-on and turn-off transitions
6. No output coupling capacitors, snubber networks or bootstrap capacitors required
7. Unity-gain stable
8. External gain configuration capability
