Voltage Reference datasheet and documents for LT1021DCH-10

LT1021DCH-10

Voltage Reference Overview

The LT1021DCH-10 is a precision voltage reference featuring an ultralow drift buried zener structure. It provides a fixed 10V output with an initial tolerance of ±0.5%. The device operates within an industrial temperature range of -40°C to 85°C and draws a typical supply current of 1.7mA. It supports sourcing and sinking up to 10mA of load current while maintaining high ripple rejection. The component is housed in an 8-lead SOIC (S8) plastic package.

Voltage Reference Feature Summary

Ultralow drift performance achieved through a buried zener diode architecture without on-chip heaters
High immunity to input voltage variations with excellent long-term stability
Capable of both sourcing and sinking up to 10mA of output current
Includes a trim pin for fine-tuning the output voltage

Voltage Reference Applications

A/D and D/A converters
Precision regulators
Digital voltmeters
Inertial navigation systems
Precision scales

Voltage Reference Procurement Notes

Verify the specific suffix 'DCH' corresponds to the industrial temperature grade (-40°C to 85°C) and the SOIC-8 package configuration. Confirm that the '-10' designation matches the required 10V output level. Ensure the ordering code includes '#PBF' if lead-free compliance is mandatory for the assembly process.

Voltage Reference Selection Notes

Select this part when system accuracy requires minimal temperature-induced error without active thermal regulation. The buried zener design offers superior noise and stability compared to standard bandgap references. Verify that the available trim range accommodates the necessary calibration adjustments for the specific application requirements.

Voltage Reference Part Context

The LT1021 family utilizes a subsurface zener technology to minimize noise and improve time stability beyond conventional bandgap designs. This approach eliminates the need for high-power internal heaters typically found in other ultra-low drift references, resulting in lower power consumption and simpler circuit implementation.
