What are the key features of LTZ1000CH#PBF?
- Ultra-precision two-terminal voltage reference with sub-ppm/°C temperature coefficient, setting the benchmark for 8.5-digit DMMs and primary voltage standards
- Output voltage range of 6.9 V to 7.45 V with buried Zener architecture provides long-term stability and exceptionally low 1/f noise
- Hermetic 8-pin metal can (TO-99) package ensures stable thermal and mechanical environment for the reference junction in metrology instruments
What is LTZ1000CH#PBF used for?
LTZ1000CH#PBF is used in primary voltage standards, laboratory-grade digital multimeters, precision ADC reference circuits, and scientific instrumentation where reference stability below 1 ppm/°C is required. Its buried Zener design provides extremely low noise and long-term drift, making it the preferred choice in secondary voltage standards that are calibrated against national metrology labs. Temperature-controlled oven enclosures further stabilize LTZ1000CH#PBF to achieve sub-0.1 ppm/°C performance in critical calibration systems.

Frequently Asked Questions
What output voltage does LTZ1000CH#PBF produce, and how stable is it over temperature?
LTZ1000CH#PBF produces an output voltage between 6.9 V and 7.45 V from its buried Zener junction. When used in a temperature-controlled circuit, its temperature coefficient can be trimmed below 0.05 ppm/°C, making it suitable for 8.5-digit DMMs and precision voltage standards requiring long-term stability.
Why is LTZ1000CH#PBF preferred over band-gap references in primary metrology applications?
LTZ1000CH#PBF uses a buried Zener architecture operating at approximately 7.1 V, which provides lower 1/f noise spectral density and better long-term stability compared to band-gap references at 1.2 V. The higher Zener voltage also reduces the relative impact of noise sources by a factor proportional to the voltage ratio, improving measurement resolution in 8.5-digit instruments.
What package does LTZ1000CH#PBF use, and how does it aid thermal stability in an oven-controlled design?
LTZ1000CH#PBF comes in an 8-pin hermetic metal can (TO-99) package, which provides thermal mass and a sealed environment that reduces moisture-driven drift. When placed inside a temperature-controlled oven circuit operating at approximately 50°C above ambient, the metal can thermally couples to the oven, allowing LTZ1000CH#PBF to achieve sub-0.1 ppm/°C stability.
In what scenarios is LTZ1000CH#PBF a better choice than the lower-cost LT1021 voltage reference?
LTZ1000CH#PBF is preferred over LT1021 when the application requires temperature coefficients below 1 ppm/°C and 1/f noise below 1 µV peak-to-peak in the 0.1 Hz to 10 Hz band. Typical LTZ1000CH#PBF applications include 8.5-digit DMM references, primary voltage standards, and precision ADC references where a 10× improvement in temperature stability justifies the cost premium.
