Description
Key features include:
- 8-bit resolution with ±0.5 LSB INL/DNL for accurate conversion.
- Differential or single-ended input with a 1 Vpp full-scale range.
- LVDS-compatible digital outputs for high-speed data transfer.
- On-chip reference and track-and-hold for simplified design.
Applications include video processing, medical imaging, and communications systems where high-speed, low-power ADCs are required. The device comes in a TSSOP-20 package for compact PCB integration.
For detailed specifications, refer to the datasheet on Analog Devices' website.
