The ADS7949SRTER is an 8-bit, 2 MSPS analog-to-digital converter from Texas Instruments, featuring 2 multiplexed input channels. Its SAR-based MUX-S/H-ADC architecture delivers fast and accurate conversions with minimal delay. The device interfaces via SPI and requires an external reference for flexible voltage scaling. Packaged in a compact 16-WFQFN with exposed pad, it operates reliably from -40°C to 125°C. This ADC is well-suited for high-speed data acquisition, industrial automation, and portable instrumentation where speed and small size are paramount.
- Fast Conversion Rate: 2 MSPS enables capture of high-frequency signals without aliasing.
- Dual-Channel Flexibility: 2:1 MUX allows for interleaved sampling of two signals.
- Low Latency SAR Architecture: Provides immediate conversion results, ideal for real-time control.
- Robust Temperature Range: -40°C to 125°C suits demanding industrial environments.
- Space-Saving Package: 16-WFQFN reduces PCB footprint for dense designs.
