XC7478E

Data Acquisition

8-bit ADCSAR ADC1 MSPSSPISOT-23-6Auto power-down

XC7478E is a 3.3 V to 4.8 V, 8-bit SAR ADC for up to 1 MSPS sampling with a 12-clock SPI-compatible serial readout.

Best for

  • Low-resolution data acquisition
  • Battery-powered measurement systems
  • Sensor interfaces using a 3.3 V to 4.8 V supply

Avoid if

  • More than 8-bit conversion resolution is required
  • The analog signal exceeds VDD
  • Documented compliance or lifecycle status is mandatory without further verification

Check before use

  • Verify the 3.3 V to 4.8 V supply range
  • Verify 20 MHz SCLK capability for 1 MSPS operation
  • Verify the 12-clock transfer and MSB-first data handling
  • Confirm package footprint and compliance status
