CS5340-DZZ

ADCs/DACs - Special Purpose Overview

The CS5340-DZZ is a stereo audio analog-to-digital converter (ADC) from Cirrus Logic, utilizing an advanced multi-bit delta-sigma architecture. It provides 24-bit resolution with a typical dynamic range of 101 dB at 5 V and -94 dB THD+N. The device supports sample rates up to 192 kHz per channel, operating within a 3.3 V to 5 V analog supply range. Integrated features include low-latency digital filters, high-pass filtering for DC offset removal, and auto-detect mode selection in slave operation. Packaged in a 16-pin TSSOP, it is designed for commercial (-10°C to +70°C) and automotive (-40°C to +85°C) temperature grades.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'DZZ' against the manufacturer's current ordering information to confirm package type and temperature grade. Confirm availability status as distribution channels may list this component as obsolete or limited stock. Ensure the source document matches the exact part number before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select the CS5340-DZZ for systems requiring wide dynamic range and negligible distortion. Verify that the system logic levels between 1.8 V and 5 V are compatible with the VL pin. Ensure the design accommodates the required master clock frequencies listed in Table 4 of the datasheet for the desired output sample rate.

ADCs/DACs - Special Purpose Part Context

The CS5340 belongs to Cirrus Logic's line of complete analog-to-digital converters for digital audio systems. It performs sampling, analog-to-digital conversion, and anti-alias filtering internally. The device generates 24-bit values for both left and right inputs in serial form. It is pin-compatible with the CS5341 model.

ADCs/DACs - Special Purpose Replacement Considerations

The CS5341 is explicitly noted as pin-compatible with the CS5340. Verify electrical specifications and feature sets of potential substitutes against the original requirements before implementation.

ADCs/DACs - Special Purpose FAQ

What is the maximum output sample rate supported by the CS5340?
