AD780BRZ

The AD780BRZ from Analog Devices is a precision 2.5 V voltage reference IC that delivers a highly stable reference for high-resolution data conversion and instrumentation circuits. An industry-standard bandgap design, this device provides both a 2.5 V output and a selectable 3.0 V output, and is characterized by an ultra-low temperature drift of 3 ppm/°C maximum (B grade) and low output noise for reliable performance over the full industrial temperature range of -40°C to +85°C. Housed in an 8-lead SOIC package with Pb-free, RoHS-compliant termination (Z suffix), the AD780BRZ achieves high initial accuracy and can source or sink up to 10 mA, making it suitable for driving both ADC references and sensor excitation.

Typical applications include precision industrial process controllers, medical imaging and monitoring equipment, aerospace telemetry systems, and high-reliability defense electronics where tight regulation and long-term stability are critical. The AD780 often serves as the voltage reference for 16- to 24-bit analog-to-digital converters, digital-to-analog converters, and precision comparator thresholds. For procurement engineers, the AD780BRZ represents a mature, widely available reference in the AD780 family with no active end-of-life alert; the industrial temperature rating and standard SOIC package simplify reflow soldering and logistics. Designers seeking extended temperature support or military qualification should examine the full AD780 series options, though the BRZ grade provides an optimal balance of cost and performance for commercial and ruggedized industrial designs.
