SINGLE CHIP PC AUDIO SYSTEM, CODEC+STEREO SPEAKER AMPLIFIER+CAPLESS HP+LDO

1. DESCRIPTION

1.1. Overview

The 92HD87 is a high fidelity, 4-channel audio codec compatible with the Intel High Definition (HD)

Audio Interface. The 92HD87 codec provides high quality, HD Audio capability to notebooks and

business desktops.

The 92HD87 is designed to meet or exceed premium logo requirements for Microsoft’s Windows

Logo Program as indicated in WLP 3.09.

The 92HD87 provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by

the DAC and ADC. The 92HD87 supports a wide range of notebook and business desktop 4-chan-

nel configurations.

An integrated BTL stereo amplifier is ideal for driving an integrated speaker in mobile, ultra-mobile,

business or desktop computers.

MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the

92HD87 has 2 General Purpose I/O (GPIO).

The port presence detect capabilities allow the codecs to detect when audio devices are connected

to the codec. Load impedance sensing helps identify attached peripherals for easy set-up and a bet-

ter user experience. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion

and removal for protection of notebook speakers.

The 92HD87 operates with a 1.5V, 1.8V or 3.3V digital supply and a 5V analog supply. It can also

work with 1.5V and 3.3V HDA signaling.

The 92HD87 is available in a 40-pin QFN Environmental (ROHS) package.
