LTZ1000ACH#PBF

Overview

The LTZ1000ACH#PBF is an ultra-precision temperature-controlled voltage reference housed in an 8-lead TO-5 metal can. It provides a nominal 7V output with a typical drift of 0.05ppm/°C and noise of 1.2µVP-P (0.1Hz to 10Hz). The device features long-term stability of 2µV/√kHr and includes a subsurface zener, heater resistor, and temperature sensing transistor. The LTZ1000A variant utilizes a proprietary die attach method yielding 400°C/W thermal resistance, reducing insulation requirements compared to the standard LTZ1000.

Feature Summary

Integrated heater control and temperature sensing for stabilized operation
Proprietary die attach method significantly increases thermal resistance
Subsurface zener reference design minimizes low-frequency noise
Specified for extended industrial temperature ranges

Applications

High-accuracy voltmeters
Precision calibrators
Standard cells
Low noise RF oscillators

Procurement Notes

Verify that the specific part number matches the required package type and lead finish. Confirm that the application circuitry supports the necessary heater control loop and thermal management. Ensure proper handling procedures are followed due to the fragile nature of the internal components within the metal can package.

Selection Notes

Select this component when extreme precision and stability are required. The LTZ1000ACH#PBF offers superior performance over older references like the LM199. Consider the higher thermal resistance of the LTZ1000A variant if minimizing external insulation complexity is a priority. Verify compatibility with existing amplifier circuits for optimal system performance.

Part Context

This component belongs to the LTZ1000 family of ultra-precision references from Analog Devices. It is designed to replace legacy high-stability references. The LTZ1000ACH#PBF specifically denotes the A-grade version with enhanced thermal characteristics packaged in a standard TO-5 metal can configuration suitable for through-hole mounting.
