Frequently Asked Questions
For a 16-bit ADC with a 2.048 V full-scale range, how does LT6654AIS6-2.048#TRMPBF's drift affect measurement accuracy?
At 10 ppm/°C drift, the LT6654AIS6-2.048#TRMPBF changes by 0.02 mV per degree Celsius, corresponding to less than 0.7 LSB shift at 16-bit resolution over a 10°C temperature change. This drift level supports 14-bit to 15-bit effective accuracy in uncompensated industrial systems operating across the -40°C to +85°C range.
How does the 2.048 V output voltage of LT6654AIS6-2.048#TRMPBF benefit binary-scaled ADC signal chains?
The 2.048 V reference value corresponds to exactly 2048 mV, so each LSB of a 12-bit ADC equals exactly 0.5 mV and each LSB of a 16-bit ADC equals 31.25 µV. This binary-friendly scaling simplifies firmware conversion factors and eliminates rounding errors in ADC reading-to-engineering-unit calculations.
Can LT6654AIS6-2.048#TRMPBF operate directly from a 3.3 V digital supply rail in a mixed-signal embedded system?
Yes, the LT6654AIS6-2.048#TRMPBF requires a minimum input supply of approximately 2.7 V to maintain its 2.048 V output within specification. A 3.3 V digital rail provides 1.25 V headroom above the output, sufficient for stable regulation, and the device draws only a few hundred µA, making it easy to power from the same 3.3 V supply used for microcontrollers and FPGAs.
What layout precautions improve the noise performance of LT6654AIS6-2.048#TRMPBF in a precision ADC board?
Place a 100 nF to 1 µF ceramic bypass capacitor within 2 mm of the LT6654AIS6-2.048#TRMPBF output pin to filter high-frequency noise. Use a dedicated analog ground plane under the SOT-23-6 footprint, keep the reference trace away from switching regulator outputs, and add a 10 µF tantalum capacitor to the supply pin to attenuate low-frequency power supply ripple below 10 µV.
