Visão Geral
Description
- 16-bit resolution with no missing codes
- SPI-compatible serial interface (3-/4-wire modes)
- Internal reference (2.5V) with low drift (5 ppm/°C typ.)
- Wide input range (0V to VREF, ±VREF with bipolar mode)
- Small 10-lead MSOP package (RL7 denotes tape-and-reel packaging)
Ideal for portable, industrial, and medical applications, it offers high accuracy, low noise, and flexible power-down modes. The internal reference simplifies design, while the robust SAR architecture ensures fast, precise conversions.
For detailed specs, refer to the datasheet.
