Especificaciones
Definición del número de pieza
AD780 is a high precision bandgap voltage reference providing fixed 2.5V stable output voltage. BR represents 8-lead narrow SOIC surface mount package, supplied in tube packaging for prototype circuit debugging and small batch production assembly.
Parámetros básicos de rendimiento eléctrico
This two-terminal precision voltage reference adopts bandgap internal architecture, delivering steady 2.500V output voltage for analog measurement circuits. It operates under input supply voltage ranging from 3V to 36V, with wide input tolerance adapting to various industrial power supply environments.
Typical temperature coefficient is controlled at 3 ppm/°C across full working temperature scope, which keeps output voltage deviation extremely small when ambient temperature fluctuates. Excellent line regulation and load regulation performance resist voltage variation caused by input power swing and output current change.
The component can source and sink small load currents directly without extra buffer amplifiers in most conventional application scenarios. Long-term voltage stability is outstanding, with tiny drift over prolonged running time to guarantee consistent calibration benchmark for measurement equipment. Quiescent operating current is kept low to reduce static power consumption for battery-powered portable instruments. Low output noise characteristics avoid noise interference to subsequent analog conversion circuits.
Especificaciones de empaque y ensamblaje
Encapsulated in compact 8-pin narrow SOIC plastic surface mount housing with small footprint, saving PCB layout space for miniaturized analog acquisition and calibration modules. Moisture Sensitivity Level is MSL3, all reflow soldering procedures need to be finished within 168 hours after the original vacuum sealed package is opened. Tube packaging supports manual breadboard testing, parameter verification and small volume trial production conveniently.
Normas ambientales y de cumplimiento
Operating temperature range covers -40°C to +85°C, supporting continuous reliable operation in industrial transmitters, laboratory precision measuring instruments, portable calibration devices and medical analytical equipment under variable temperature conditions. Manufactured through lead-free production processes, the component meets global RoHS environmental standards. Simple peripheral circuit structure reduces usage of auxiliary passive components and simplifies high-precision analog reference circuit design.
