AD780ARZ

Overview

The AD780ARZ is an ultrahigh precision band gap reference voltage IC manufactured by Analog Devices Inc. It provides a pin-programmable output of either 2.5 V or 3.0 V from input voltages ranging between 4.0 V and 36 V. The device features a maximum temperature drift of 3 ppm/°C, high accuracy with a maximum initial error of ±1 mV, and low noise performance of 100 nV/√Hz. It operates within a specified temperature range of −40°C to +85°C and is housed in an 8-lead SOIC package.

Feature Summary

Pin programmable for 2.5 V or 3.0 V output selection
Ultralow drift and high accuracy via laser trimming
Capable of sourcing or sinking up to 10 mA
Includes dedicated temperature output pin

Applications

High resolution analog-to-digital converters (ADCs)
Digital-to-analog converters (DACs)
General-purpose precision reference applications
Temperature transducer circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and quantity. Ensure the component meets RoHS compliance requirements as indicated by the 'Z' suffix. Confirm that the supply voltage and load conditions align with the absolute maximum ratings to prevent damage during operation.

Selection Notes

Select this component when a high-precision reference with low headroom is required. It serves as a direct pin-compatible upgrade for LT1019(A)–2.5 and AD680 references. Consider its ability to drive large capacitive loads without instability and its suitability for enhancing dynamic range in 5 V data converters.

Part Context

The AD780 series includes grades AN, AR, BN, BR, and CR, all specified for operation from −40°C to +85°C. The AD780ARZ specifically denotes the A-grade version packaged in an 8-lead SOIC_N format. This part belongs to the broader family of high-performance voltage references designed for demanding industrial and scientific applications.
