ADS8638SRGER

The ADS8638SRGER is a 16-bit, 8-channel, successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a wide input range (±12.288V, ±6.144V, ±3.072V, or 0–12.288V), selectable per channel, and operates at 1MSPS.
Key features include:
- High accuracy (INL: ±1 LSB, SNR: 92dB).
- Integrated reference and buffer for simplified design.
- SPI-compatible interface for easy microcontroller communication.
- Low power consumption (10.5mW at 1MSPS).
Housed in a 24-pin VQFN (RGE) package, it’s ideal for industrial automation, power monitoring, and data acquisition systems. The device supports bipolar/unipolar inputs and includes auto-scan modes for efficient multi-channel sampling.
For detailed specs, refer to the datasheet (SBAS586) on TI’s website.
