Overview
The AD1886JST-REEL is an AC'97 SoundMAX codec manufactured by Analog Devices Inc. It features a 48-terminal LQFP package and operates within a temperature range of 0°C to 70°C. The device supports split power supplies, utilizing a 3.0 V to 3.6 V digital supply (DVDD) and a 4.75 V to 5.25 V analog supply (AVDD). It includes stereo headphone amplifiers, four analog line-level stereo inputs, and two mono inputs. The codec provides full-duplex variable sample rates from 7040 Hz to 48 kHz with 1 Hz resolution and supports 20-bit SPDIF output at symbol rates of 32 kHz, 44.1 kHz, and 48 kHz.
Feature Summary
- AC'97 2.2 compliant architecture supporting variable sample rate audio
- Integrated stereo headphone amplifier with jack sense functionality for automatic output switching
- Multibit delta-sigma converter architecture ensuring high signal-to-noise ratio performance
- Software-enabled VREFOUT output designed for microphone biasing and external power amplifier control
Applications
- Desktop PC audio subsystems
- Telephony speakerphone integration
- Mobile low-power mixer applications
Procurement Notes
Verify the component matches the AD1886A datasheet specifications exactly. Confirm the ordering suffix indicates the reel packaging format. Ensure the manufacturer is Analog Devices Inc. and the package type is 48-lead LQFP. Check that the operating temperature range aligns with commercial requirements.
Selection Notes
Select this component for systems requiring AC'97 2.2 compliance and integrated stereo headphone driving capabilities. Consider the split power supply requirement when designing the board layout. Evaluate the need for variable sample rate generation and SPDIF output features against system audio processing demands.
Part Context
This part belongs to the AD1886 series of AC'97 codecs. It is functionally compatible with other variants in the family but differs in package style and temperature rating. The JST suffix specifically denotes the 48-lead LQFP package option suitable for surface mount assembly.
Replacement Considerations
Check for AD1886AJST without the REEL suffix if tape-and-reel packaging is not required. Verify compatibility with AD1819 or AD1819A backward compatibility modes if legacy register mapping is necessary.
