Frequently Asked Questions
How accurate is the LT1004CZ-1.2#PBF reference output and what does ±0.3% mean in practice?
LT1004CZ-1.2#PBF has an initial output voltage accuracy of ±0.3%, corresponding to an output range of 1.225 V to 1.245 V around the nominal 1.235 V. For a 12-bit ADC reference application, this means a worst-case initial offset of about 4 LSB, which may require calibration in high-precision data acquisition designs.
What is the maximum operating current for LT1004CZ-1.2#PBF when used as a shunt reference?
LT1004CZ-1.2#PBF can operate with up to 20 mA of shunt current. In a typical two-terminal configuration, a series resistor sets this current from the supply rail, and the device maintains its regulated 1.235 V output across the biasing range, simplifying reference circuit design.
Is LT1004CZ-1.2#PBF suitable for 3.3 V powered portable instrument designs?
Yes. LT1004CZ-1.2#PBF provides a 1.235 V reference output that sits comfortably within a 3.3 V supply headroom. Its low reference voltage and 2-terminal shunt topology work well in battery-powered portable instruments, handheld meters, and IoT sensor modules requiring a stable sub-1.3 V analog reference.
How does the TO-92-3 package of LT1004CZ-1.2#PBF compare to SOT-23 alternatives for prototyping?
The TO-92-3 through-hole package is larger than SOT-23 SMD alternatives but allows easy soldering on breadboards and through-hole PCBs, which makes LT1004CZ-1.2#PBF a preferred choice during prototype and lab evaluation stages before transitioning to a surface-mount equivalent for production boards.
