Description
The ADS1278HPAP is a high-performance, 24-bit, delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features 8 simultaneous sampling channels with data rates up to 144 kSPS per channel, making it ideal for precision applications like industrial sensing, medical imaging, and vibration analysis.
Key features include:
- High resolution (24-bit) with low noise (1.5 µV RMS at 52 kSPS).
- Flexible data interface (SPI or frame-sync serial).
- Wide dynamic range (up to 109 dB SNR).
- Low power consumption (57 mW/channel in high-speed mode).
- Integrated digital filters for noise reduction.
The HPAP package (HTQFP-64) ensures robust thermal and mechanical performance. The ADC supports daisy-chaining for multi-device synchronization and operates from ±2.5V analog and 1.8V–3.3V digital supplies.
Applications include data acquisition systems, seismic monitoring, and audio analysis, where high accuracy and simultaneous sampling are critical.
