Applications
The LT1004IZ-2.5#PBF serves as a precision voltage reference in battery-powered data acquisition systems and portable instruments where a stable 2.5 V rail is needed for ADC or DAC biasing. Its simple two-terminal shunt topology allows direct placement across supply lines in power management circuits without additional regulation components. Industrial control cards and 4–20 mA current-loop transmitters also benefit from the device's accurate 2.5 V output and wide operating temperature range of -40°C to 85°C.

Frequently Asked Questions
How accurate is the LT1004IZ-2.5#PBF output voltage, and what does that mean for ADC reference accuracy in a 12-bit system?
The LT1004IZ-2.5#PBF guarantees a 2.5 V output with ±0.8% initial accuracy, equating to a worst-case offset of ±20 mV. In a 12-bit ADC system with a 2.5 V reference, this translates to a potential full-scale error of roughly ±33 LSBs, so calibration is recommended when error budgets are tight below 10-bit effective resolution.
What current range does the LT1004IZ-2.5#PBF support, and how should the bias resistor be calculated for a 5 V supply?
The device operates from 20 µA to 20 mA of shunt current. For a 5 V supply, selecting a bias resistor of (5 V − 2.5 V) / 1 mA = 2.5 kΩ sets a comfortable 1 mA quiescent point well within the 20 µA to 20 mA window, providing stable 2.5 V regulation across typical load variations.
Over what temperature range does the LT1004IZ-2.5#PBF maintain its voltage reference specification?
The LT1004IZ-2.5#PBF is specified over an industrial temperature range of -40°C to 85°C. Across this range, the two-terminal shunt design maintains a low temperature coefficient, keeping the 2.5 V output within its accuracy band for applications in outdoor instrumentation, automotive accessories, and factory automation equipment.
When would a designer choose the LT1004IZ-2.5#PBF shunt reference over a bandgap series reference in a battery-powered circuit?
A shunt reference like the LT1004IZ-2.5#PBF is preferred when the circuit already limits current through a series resistor, avoiding the need for an additional dropout regulator. At quiescent currents as low as 20 µA, it suits sleep-mode sensors and 3 V to 5 V battery systems where the simplicity of a 2-pin device reduces both component count and PCB area.
