Cx31993 Datasheet [portable] [ NEWEST ✔ ]
The CX31993 is a dual-channel, 24-bit audio codec (coder-decoder) chip developed by Sony. Here's a brief report based on its datasheet:
| Measurement | Result | | :--- | :--- | | Frequency Response Variation (40Hz-15kHz) | -0.1 dB to +0.0 dB | | Output Impedance (Average, 40Hz-15kHz) | 0.2Ω | | Voltage Output (Maximum, before clipping) | 1.0 VRMS | | Current Output (Maximum) | 51.3 mA | | Crosstalk @ 1kHz (100Ω load) | -60.5 dB |
This is the most common application for the CX31993. As smartphones increasingly omit the traditional headphone jack, these adapters provide a compact, affordable solution for connecting wired headphones to USB-C devices. The chip's ultra-low power consumption ensures minimal battery drain, while its high-quality DAC provides a significant improvement over many built-in smartphone audio solutions. cx31993 datasheet
This technical analysis compiles parameters, functional block architecture, hardware design considerations, and performance benchmarks typically documented across an engineering datasheet. 1. Architectural Overview & Block Diagram
She started small. A breadboard, an old microcontroller, a handful of capacitors she scavenged from broken equipment. Late into the night, the CX31993’s oscillator hummed in translucent green on the scope, its timing edges neat as a metronome. The datasheet's “Absolute Maximum Ratings” page, which the less meticulous often ignored, had saved her a charred MOSFET and a migraine; its “Typical Operating Characteristics” page taught her patience. Each clause in the document folded into her routine—she measured propagation delay the way others measure coffee intake. The CX31993 is a dual-channel, 24-bit audio codec
The has rapidly become a staple in the world of portable audio. As a highly integrated USB Type-C digital-to-analog converter (DAC) SoC, it is the engine behind many of the high-performance "dongle DACs" that audiophiles use to bypass inferior smartphone audio circuitry.
