What are the key features of LT6654AIS6-1.25#TRMPBF?
- 1.25 V precision output with ±0.05% initial accuracy for tight ADC reference calibration
- 10 ppm/°C maximum temperature coefficient ensuring stable reference voltage across -40°C to 85°C industrial range
- Low-noise SOT-23 6-pin package enabling compact precision voltage reference placement adjacent to ADC inputs
What is LT6654AIS6-1.25#TRMPBF used for?
The LT6654AIS6-1.25#TRMPBF is designed for precision analog-to-digital converter references, calibration circuits, and data acquisition systems requiring a stable 1.25 V reference with minimal temperature drift. Its 10 ppm/°C temperature coefficient ensures that a 16-bit ADC using this reference introduces less than 1 LSB of reference-induced error across a 50°C operating temperature span. The compact SOT-23 footprint makes it suitable for portable instrumentation, medical diagnostic equipment, and industrial transmitters where board space is limited.

Frequently Asked Questions
How accurate is the 1.25 V output of LT6654AIS6-1.25#TRMPBF and what output voltage tolerance can be expected?
The LT6654AIS6-1.25#TRMPBF specifies an output voltage range of 1.24781 V to 1.25219 V, representing an initial accuracy of approximately ±0.175% or better. At 10 ppm/°C temperature coefficient, a 50°C temperature change causes an additional drift of only 0.625 mV, making the reference suitable for driving 14-bit and 16-bit ADCs where total reference error must remain below 1 LSB.
Which precision measurement applications benefit most from the 10 ppm/°C specification of LT6654AIS6-1.25#TRMPBF?
Precision weigh scales, industrial pressure transmitters, and medical blood glucose analyzers benefit most from the 10 ppm/°C drift specification. In a 4-20 mA loop transmitter operating over a -40°C to 85°C range, a 10 ppm/°C reference contributes only 1.25 mV of total drift versus 5 mV or more from a 40 ppm/°C standard reference, directly improving span accuracy to within 0.1% of reading.
How does LT6654AIS6-1.25#TRMPBF compare to a 2.5 V reference when used as an ADC reference for a 3.3 V supply system?
A 1.25 V reference like the LT6654AIS6-1.25#TRMPBF is advantageous when the ADC input signal spans 0 V to 1.25 V, maximizing the full-scale input range and dynamic range without requiring a resistor divider on the reference output. However, a 2.5 V reference provides 6 dB better signal-to-noise ratio for the same ADC resolution when the analog input spans the full 2.5 V range, so the choice depends on sensor output swing relative to the available supply headroom.
