What is LT1021DCS8-10#PBF used for?
The LT1021DCS8-10#PBF serves as a precision reference voltage source for 14-bit to 16-bit ADC and DAC circuits in industrial data acquisition systems, where tight 10V output stability over temperature is critical. It is commonly used in precision instrumentation, calibration standards, and strain gauge bridge excitation circuits requiring a stable 10V reference over the full industrial temperature range. Its three-terminal configuration allows trim adjustment for achieving sub-10ppm/°C performance in demanding metrology applications.

Frequently Asked Questions
What initial output accuracy does the LT1021DCS8-10#PBF provide and how does it affect 16-bit ADC performance?
The LT1021DCS8-10#PBF guarantees an output voltage between 9.95V and 10.05V, representing ±0.05% initial accuracy. For a 16-bit ADC with a 10V full-scale range, each LSB corresponds to approximately 152µV; at ±50mV reference error the initial gain error is 328 LSBs, which is why calibration trim is used in high-resolution designs to bring the reference within 1 LSB accuracy.
What temperature coefficient does the LT1021DCS8-10#PBF offer and for which precision measurement environments is it appropriate?
The LT1021DCS8-10#PBF specifies a maximum temperature coefficient of 20 ppm/°C. Over a 100°C operating range, this yields a maximum output drift of 20mV, which is adequate for 12-bit to 14-bit precision data acquisition systems. For metrology-grade 16-bit performance, the D-grade selection with trimming can achieve sub-5 ppm/°C in controlled laboratory environments.
How does LT1021DCS8-10#PBF compare to using an LT1021-5 for a 10V reference in a 12V-powered industrial instrument?
The LT1021DCS8-10#PBF provides a 10V reference output directly from a 12V supply with typically 1.0mA to 10mA output current capability, whereas the LT1021-5 only provides 5V and would require a gain-of-2 amplifier stage to reach 10V, adding noise and error. Choosing the 10V variant simplifies the signal chain for instruments needing a 10V full-scale range for ±5V bipolar measurement front-ends.
What supply voltage range and quiescent current does LT1021DCS8-10#PBF require for reliable operation?
The LT1021DCS8-10#PBF requires a minimum supply voltage of approximately 12V (10V output plus 2V headroom) and operates up to 30V, drawing a quiescent current typically around 1.0mA to 5mA depending on load. This makes it suitable for 12V to 24V industrial rack-mount instruments and bench-top calibrators, while its SO-8 footprint keeps PCB area impact minimal.
