The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents latch-up.
The TLV1549CP outputs data in a 2's complement format. To convert it to a signed integer, simply invert the MSB and add 1 to get the correct signed value.
The maximum sampling rate of the TLV1549CP is 40 kHz. However, the actual sampling rate may be limited by the system's clock frequency and the analog input signal's bandwidth.
Calibration is not required for the TLV1549CP, as it is a self-calibrating ADC. However, ensuring proper power supply decoupling, analog input signal conditioning, and a stable clock signal are essential for optimal performance.
Clock jitter can affect the TLV1549CP's performance by introducing noise and reducing the effective resolution. It is recommended to use a low-jitter clock source and to decouple the clock signal properly to minimize its impact.
