Frequently Asked Questions
What is the effective number of bits (ENOB)?
The TPC1610 achieves approximately 14.5 effective bits (ENOB) at 1MSPS sample rate with a 1kHz input signal. The ENOB is the actual dynamic performance considering noise and distortion. For DC measurements, the full 16-bit resolution is available.
14.5 ENOB at 1MSPS is good for most applications. Reduce sample rate for better dynamic performance.
What is the SPI interface timing?
The TPC1610 uses SPI Mode 0 (CPOL=0, CPHA=0). Key timing parameters: SCLK frequency up to 50MHz, CS setup time 10ns min, CS hold time 10ns min, Data setup time 5ns min, Data hold time 5ns min. Conversion is initiated on CS falling edge, and data is clocked out on SCLK rising edge. Total conversion time is approximately 1μs at 1MSPS.
Use SPI Mode 0. Ensure SCLK frequency and timing meet datasheet requirements.
How do I calculate the LSB size?
LSB (Least Significant Bit) size = Vref / 2^16. For TPC1610 with 2.5V reference: LSB = 2.5V / 65536 = 38.15μV. This means each code change is approximately 38μV. For 5V reference: LSB = 76.3μV. Understanding LSB helps determine if the ADC resolution is sufficient for your measurement requirements.
Calculate LSB based on your reference voltage. Ensure it's smaller than your required measurement resolution.
What input driver amplifier should I use?
The TPC1610 requires a driver amplifier that can settle to 16-bit accuracy within the acquisition time. Recommended: TP1561 for precision low-speed signals, TP167x for high-speed signals. Key requirements: Sufficient bandwidth (>10x sample rate), Low output impedance, Fast settling time. The driver must charge the ADC sampling capacitor (typically 20pF) to 0.0015% accuracy (1/2 LSB) within the acquisition window.
Use TP1561 for most applications. Ensure driver has sufficient bandwidth and settling time.
Can I use TPC1610 in a multiplexed system?
Yes, TPC1610 is well-suited for multiplexed systems due to its fast conversion time (1μs) and low latency. When multiplexing: Allow adequate settling time after channel switching (typically 100-500ns), Use appropriate anti-aliasing filters for each channel, Consider using a buffer amplifier per channel or a fast-settling mux amplifier. Maximum aggregate throughput depends on number of channels and required sample rate per channel.
Excellent for multiplexed systems. Allow settling time between channel switches.
