Description
The ADS8684IDBTR is a 16-bit, 500 kSPS, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features ±10.24V, ±5.12V, or ±2.56V programmable input ranges, making it suitable for industrial and automation applications.
Key features:
- Integrated analog front-end (AFE) with overvoltage protection (±20V).
- Low power consumption (5.5 mW/channel at 500 kSPS).
- SPI-compatible serial interface for easy microcontroller interfacing.
- On-chip reference and buffer for simplified design.
Packaged in a TSSOP-38 (DBT) form factor, it’s ideal for space-constrained systems. Applications include data acquisition, power monitoring, and motor control.
