Conductivity meter, ELEMENT design

The Bürkert conductivity meter Type 8222 is designed for measuring the conductivity of fluids. The sensor element comprises a two-electrode cell and a Pt1000 temperature probe. The sensor itself is available with three different cell constants C. These with C= 0.01 or 0.1 cm- 1 are fitted with

LOW-DROPOUT REGULATORS . HIGH EFFICIENCY

LOW-DROPOUT REGULATORS — HIGH EFFICIENCY Designed specifically to meet the requirement for extended operation of battery-powered equipment such as cordless and cellular telephones, the A8220SLH thru A8233SLH voltage regulators offer the reduced dropout voltage and quiescent current essential fo

10 MHz, 20 V/關s, G = 1, 10, 100, 1000 i CMOS짰 Programmable Gain Instrumentation Amplifier

GENERAL DESCRIPTION The AD8253 is an instrumentation amplifier with digitally programmable gains that has GΩ input impedance, low output noise, and low distortion making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs). It has high bandwidt

Precision, Dual-Channel Instrumentation Amplifier

GENERAL DESCRIPTION The AD8222 is a dual-channel, high performance instrumentation amplifier that requires only one external resistor per amplifier to set gains of 1 to 10,000. The AD8222 is the first dual-instrumentation amplifier in the small 4 mm × 4mm LFCSP. It requires the same board area a
