The AD1838AAS is a 24-bit stereo audio CODEC from Analog Devices Inc. It integrates two analog-to-digital converters (ADCs) and six digital-to-analog converters (DACs) in a single device, making it suitable for multi-channel audio applications. The CODEC supports serial data interface and operates with analog and digital supply voltages of 4.5V to 5.5V.
Key performance specifications include a typical SNR of 105 dB for the ADC and 108 dB for the DAC, with dynamic range matching the SNR. Total harmonic distortion plus noise (THD+N) is typically -95 dB for both ADC and DAC. The maximum sample rate is 96 kHz for all channels, with one DAC capable of 192 kHz. The device features sigma-delta modulation and supports 16-, 20-, and 24-bit word lengths.
The CODEC is designed for a variety of audio applications including DVD players, home theater systems, automotive audio systems, and digital audio effects processors. It includes on-chip volume controls with 1024-step linear scaling, clickless mutes, and digital de-emphasis processing. The device also supports TDM interface mode for multiple I/O streams.
The AD1838AAS is housed in a 52-lead MQFP plastic package (52-MQFP 10x10mm) and is surface mountable. It operates over the industrial temperature range of -40°C to 85°C. The part is RoHS compliant (unverified) and has an MSL rating of 1 (unlimited).
Analog and digital supply voltage range is 4.5V to 5.5V.
-40°C to 85°C.
52-lead MQFP (10x10mm) surface mount package.
The device is indicated as RoHS3 compliant, but this is unverified and should be confirmed with official sources.
It has 2 ADCs and 6 DACs.
The ADC supports up to 96 kHz, and one DAC supports up to 192 kHz.
ADC SNR is 105 dB typical, DAC SNR is 108 dB typical. THD+N is -95 dB typical for both.
