Frequently Asked Questions
What output voltage and accuracy does the ADR434TRZ-EP-R7 provide?
The ADR434TRZ-EP-R7 provides a 4.096 V reference output with an initial accuracy of ±0.04% maximum and a low temperature coefficient of typically 3 ppm/°C, making it suitable for high-resolution 16-bit and 18-bit data-conversion applications.
How does the ADR434TRZ-EP-R7 XFET architecture benefit noise-sensitive designs?
The XFET (extra-low-noise FET) architecture achieves a peak-to-peak noise of only 2 µVp-p over the 0.1 Hz to 10 Hz band, which is critical for precision ADC reference inputs where low-frequency noise directly degrades effective number of bits (ENOB).
What is the significance of the Enhanced Product (EP) designation on the ADR434TRZ-EP-R7?
The EP designation means the device has passed stricter Analog Devices qualification tests for extended reliability and is guaranteed for a minimum of 7 years of continued production, making it suitable for long-lifecycle industrial, medical, and defense designs that require supply continuity over 10+ year product runs.
Which package does ADR434TRZ-EP-R7 use and what are its supply voltage requirements?
The ADR434TRZ-EP-R7 is housed in an 8-pin SOIC (R-8) package. It operates from a supply voltage of 5 V to 15 V, consumes typically 1 mA quiescent current, and supports output source current up to 10 mA, fitting easily into space-constrained PCB layouts.
