The AD1885JST is an AC'97 2.1-compliant audio codec from Analog Devices, designed for high-quality audio processing in PC and embedded applications. It integrates a 16-bit stereo full-duplex codec with two ADCs and two DACs, supporting variable sample rates from 7040 Hz to 48 kHz with 1 Hz resolution. The codec achieves greater than 90 dB dynamic range for both ADC and DAC paths, ensuring clear audio reproduction.
Key features include a stereo headphone amplifier, four analog line-level stereo inputs (LINE-IN, CD, VIDEO, AUX), two mono inputs for speakerphone and PC BEEP, and a mono MIC input with built-in 20 dB preamp. The device also supports power management, external audio power-down control, and multiple codec configuration options. The sigma-delta converter architecture contributes to improved signal-to-noise ratio.
The AD1885JST is supplied in a 48-terminal LQFP package (48-LQFP 7x7 mm) with surface mount gull wing leads. It operates from a 4.75V to 5.25V supply and over a 0°C to 70°C temperature range. The codec is suitable for audio subsystems requiring AC'97 compatibility and high dynamic range.
The supply voltage range is 4.75V to 5.25V.
The device is supplied in a 48-LQFP package (7x7 mm) with surface mount gull wing leads.
The operating temperature range is 0°C to 70°C.
