Frequently Asked Questions
What resolution and linearity does TLC3548CPWG4 provide for precision measurement applications?
TLC3548CPWG4 delivers 14-bit resolution providing 16,384 discrete levels with a maximum linearity error of only 0.0061%, equivalent to approximately 1 LSB INL at 14 bits. This precision level is sufficient for 0.01% full-scale measurement accuracy in process control instrumentation calibrated to ±4.07 V analog input range.
How many analog input channels does TLC3548CPWG4 support, and at what sampling rate?
TLC3548CPWG4 integrates 8 analog input channels multiplexed to a single 14-bit SAR ADC core with 2.785 µs maximum conversion time. This supports a per-channel sampling rate of approximately 358 kSPS when scanning all 8 channels sequentially, adequate for monitoring multiple slow-varying process variables at 1 kHz to 10 kHz bandwidths.
What analog input voltage range does TLC3548CPWG4 accept, and is it compatible with 3.3 V sensor outputs?
TLC3548CPWG4 accepts analog input voltages from 0 V up to 4.07 V maximum, which covers the 0 V to 3.3 V range of modern low-voltage sensors without clamping. A reference voltage of 4.096 V gives a convenient 250 µV per LSB step at 14-bit resolution, simplifying calibration for thermocouple and strain gauge signal conditioners.
How does TLC3548CPWG4 interface with microcontrollers, and how many GPIO pins are required?
TLC3548CPWG4 uses a 4-wire SPI-compatible interface requiring chip select, serial clock, MOSI, and MISO lines — only 4 GPIO pins regardless of the 8 analog channels. Channel selection is sent as part of the SPI command word, eliminating the 8 separate analog multiplexer address pins needed with parallel-interface ADCs and reducing PCB routing complexity.
