Frequently Asked Questions
What resolution and sample rate does the AD1835AASZ support for audio conversion?
The AD1835AASZ provides 24-bit resolution across all channels and supports sample rates up to 96 kSPS, delivering wide dynamic range and low noise suitable for high-fidelity audio applications such as DVD audio playback and digital mixing.
How many DAC and ADC channels does the AD1835AASZ integrate, and what interface does it use?
The AD1835AASZ integrates 8 DAC channels and 2 ADC channels in a single device, communicating via an I2S serial interface. This combination enables full 7.1-channel surround-sound output plus stereo input within a compact 52-pin MQFP footprint.
Which package does the AD1835AASZ use, and how does that affect PCB layout in space-constrained designs?
The AD1835AASZ uses a 52-pin MQFP package with 0.5 mm pitch, offering a square body of approximately 10 mm x 10 mm. This compact footprint simplifies routing in densely populated audio PCBs while still accommodating all analog and digital I/O pins.
When would a designer choose AD1835AASZ over a stereo audio codec for a home theater project?
A designer targeting 7.1-channel home theater systems needs at least 8 DAC channels to drive all speaker outputs. The AD1835AASZ delivers 8 independent DAC channels at 24-bit, 96 kSPS, making it a direct fit where a stereo codec with only 2 output channels would require multiple devices and added complexity.
