ZXRE1004DR

Overview

The ZXRE1004DR is a discontinued 1.22V bandgap voltage reference in an E-Line (TO-92) package. It provides a fixed output with 1% initial accuracy and operates within a temperature range of -40°C to +85°C. The device features a typical temperature coefficient of 20ppm/°C and maintains stability over an operating current range of 8µA to 20mA.

Feature Summary

• Provides a stable 1.22V reference suitable for precision applications
• Designed for ultra-low power consumption with a typical knee current of 4µA
• Unconditionally stable operation tolerant of capacitive loads

Applications

• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• A/D and D/A converters

Procurement Notes

This component is officially obsolete and not recommended for new designs. Verify availability through secondary market channels only, as Diodes Incorporated has ceased production. Confirm the specific revision and pinout compatibility before integrating into any legacy system maintenance or replacement project.

Selection Notes

Select this part only for existing designs requiring a direct replacement for older references. Consider tighter tolerance variants if higher precision is needed, though they are also subject to obsolescence. Ensure the application can accommodate the specified operating current range and thermal characteristics.

Part Context

The ZXRE1004 series serves as a high-performance alternative to legacy references like the REF1004 and LT1004. The E-Line package offers a pin-for-pin compatible footprint for through-hole mounting, facilitating upgrades in space-constrained portable devices without requiring significant PCB layout changes.

Replacement Considerations

Officially recommended substitute: ZXRE125.
