This document describes the features and characteristics of the 114 dB, 192 kHz 6-channel D/A converter produced by Cirrus Logic, Inc. in 2005. It includes advanced multi-bit Delta Sigma architecture, 24-bit conversion, automatic detection of sample rates up to 192 kHz, 114 dB dynamic range, -100 dB THD+N, direct stream digital mode, and more.
The CS4365 is a 6‑channel, 24‑bit digital‑to‑analog converter designed for high‑performance audio applications such as SACD players, sound cards, and automotive audio systems. It features a 114 dB dynamic range, selectable digital filters, and direct‑stream‑digital (DSD) support.
This datasheet includes pin descriptions, electrical specifications, register maps, application notes, and ordering information. Engineers can use the tables and figures to integrate the device, verify power requirements, and configure the serial audio interface and control port.
| Analog power (VA) typical | 5.0 V |
|---|---|
| Digital internal power (VD) typical | 2.5 V |
| Serial data port interface power (VLS) typical | 5.0 V |
| Control port interface power (VLC) typical | 5.0 V |
| Specified temperature range | -10 °C to +70 °C |
| Absolute maximum analog power (VA) | 6.0 V |
The CS4365 provides a dynamic range of 114 dB.
It is a 6‑channel digital‑to‑analog converter.
The analog section uses a 5 V supply (VA) and the digital section uses a 2.5 V supply (VD).
