PCM1865 datasheet


Description :

The PCM186x family (PCM1860, PCM1861, PCM1862, PCM1863, PCM1864, and PCM1865 ) of audio front-end devices takes a new approach to audio-function integration to ease compliance with European Ecodesign legislation while enabling high-performance end products. With no need for a 5-volt supply or an external programmable-gain amplifier, smaller, smarter products are feasible at reduced cost. The PCM186x’s highly flexible audio front end supports input levels from small-mV microphone inputs to 2.1V RMS line Inputs without external resistor dividers. The PCM186x family integrates many system-level functions that assist or replace some DSP functions.

92HD81 datasheet pdf

Description :

The 92HD81 single-chip audio system is a low power optimized, high fidelity, 4-channel audio codec with integrated speaker amplifier, capless headphone amplifier, and low drop out voltage regulator. The high integration of the 92HD81 enables the smallest PCB footprint with the lowest system BOM count and cost. The integrated high-pass filter allows for speaker protection.

Features :

• 4 Channels (2 stereo DACs and 2 stereo ADCs) with 24-bit resolution

• Supports full-duplex stereo audio and simultaneous VoIP

• Provides a mono output

• 2W/channel stereo speaker amplifier @ 4 ohms and 4.75V

• Two headphone amplifiers

• One capless and one non-capless retaskable

• Internal core voltage regulator

• 1.5V to 1.8V or 3.3V digital power supply options

• +5 V analog power supply option

• Dedicated BTL high pass filter for speaker
