ADS7815U Frequently Asked Questions (FAQ)

  • The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input voltage. This ensures proper internal biasing and prevents latch-up.

  • To minimize noise, keep the analog input traces short and away from digital signals. Use a solid ground plane, and decouple the power supplies with 0.1uF and 10uF capacitors. Also, ensure the analog input signals are properly terminated and filtered.

  • The maximum sampling rate of the ADS7815U is 150 kSPS. However, this rate may vary depending on the specific application, operating conditions, and system design.

  • The ADS7815U outputs data in straight binary format. The most significant bit (MSB) is the sign bit, and the remaining bits represent the magnitude of the converted value.

  • The ADS7815U has an internal clock, but you can also use an external clock source. If using an external clock, ensure it is a stable, low-jitter clock signal with a frequency between 1 MHz and 20 MHz.
