The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signals. This ensures proper device operation and prevents latch-up.
The TLC1543QDBR outputs data in a serial format, with the most significant bit (MSB) first. The output data is also binary two's complement, so the user needs to take this into account when processing the data.
The maximum sampling rate of the TLC1543QDBR is 200 kHz, but this can be affected by the clock frequency, analog input frequency, and other system-level factors.
To minimize noise and interference, use proper PCB layout techniques, such as separating analog and digital grounds, using bypass capacitors, and shielding the device from electromagnetic interference (EMI).
Yes, the TLC1543QDBR can be used in a multi-channel application by using multiple devices or by using a multiplexer to switch between multiple analog input channels.
