ADC121S655CIMM/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a layout and routing guide in the application note SLAA523, which recommends a symmetrical layout, minimal trace length, and proper decoupling to reduce noise and ensure accurate conversions.
  • The ADC121S655CIMM/NOPB has an internal calibration feature that can be enabled through the CAL pin. Additionally, external calibration can be performed using an external voltage reference and adjusting the offset and gain registers. Refer to the datasheet and application notes for detailed calibration procedures.
  • The maximum sampling rate of the ADC121S655CIMM/NOPB is 1 MSPS. However, the power consumption increases with the sampling rate. At 1 MSPS, the typical power consumption is around 12 mW. Refer to the datasheet for power consumption vs. sampling rate curves.
  • Yes, the ADC121S655CIMM/NOPB can be used in a multi-channel application. It has a built-in multiplexer that allows up to 4 channels to be connected. The channels can be selected using the CH[1:0] pins, and the conversion sequence can be programmed using the SEQ[1:0] pins. Refer to the datasheet for detailed configuration and programming information.
  • The recommended voltage reference for the ADC121S655CIMM/NOPB is an external voltage reference with a low noise and high stability, such as the REF3020 or REF3030 from Texas Instruments. The voltage reference affects the accuracy of the ADC, and a high-quality reference is essential to achieve the specified accuracy of ±1 LSB.
