概述
Description
The PCM1798DBR is a high-performance, 24-bit, 192kHz digital-to-analog converter (DAC) from Texas Instruments. It features low distortion (-120dB THD+N) and high dynamic range (123dB), making it ideal for high-end audio applications like professional audio equipment, home theater systems, and digital audio workstations.
Key features:
- 24-bit resolution with 192kHz sampling rate
- Differential current output for improved noise rejection
- On-chip digital filter (8× oversampling)
- I²S and left-justified input formats
- Low power consumption (26mW typical)
The PCM1798DBR comes in a SSOP-28 package and supports ±2.5V to ±5V analog supply, ensuring flexibility in design. Its high signal-to-noise ratio (SNR) and low jitter sensitivity enhance audio fidelity, making it a popular choice for audiophiles and professional audio engineers.
For detailed specs, refer to the official datasheet.
