Présentation
Description
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.
Equivalent
1. ADS127L01 (lower power, similar performance)
2. ADS131A04 (4-channel, high-resolution)
3. AD7768-4 (24-bit, high-speed, from Analog Devices)
4. LTC2500-32 (32-bit, low noise, from Linear Tech)
5. MAX11270 (24-bit, low-power, from Maxim Integrated)
These offer comparable resolution, speed, or power efficiency. Check datasheets for exact specs.
