REF02 Voltage Reference

 

 

GENERAL Description

The REF02 precision voltage reference providesa stable 5V output that can be adjustedover a ±6% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 7 V to40 V, low current drain of1 mA, and excellent temperature stability are achieved with an improvedband gap design. Lowcost, low noise,and low power make the REF02 an excellent choice when ever a stable voltage referenceisre quired. Applications include DACs and ADCs, portable instrumentation, and digital volt meters. The versatility of the REF02 is enhanced by its use as a monolithic temperature transducer. For new designs, refer to the ADR02.

AD620 Datasheet – Instrumentation Amplifier – Analog Devices

Posted on by pinout

Part Number: AD620

Function: Low Cost/ Low Power Instrumentation Amplifier

Package: DIP, SOIC 8 Pin Type

Manufacturer: Analog Devices

Description

The AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620 features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications.

The AD620, with its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 µV max, and offset drift of 0.6 µV/°C max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. Furthermore, the low noise, low input bias current, and low power of the AD620 make it well suited for medical applications such as ECG and noninvasive blood pressure monitors.
