With the industry’s largest portfolio of DDS-based signal sources, transimpedance amplifiers for measurement, and low-resistance switches, ADI offers a complete suite of components suitable for building discrete, high-performance LCR meters for applications ranging from 1 kHz to more than 100 MHz. In addition, ADI offers a family of ARM Cortex™-M3-based, single-chip solutions incorporating high resolution ADCs suitable for a variety of handheld and portable applications.
LCR Meters and Impedance Measurement: ADI's large family of DDS signal sources, op-amp-based transimpedance amplifiers, high-speed differential amplifiers, and high-speed, high resolution ADCs allow designers to implement circuits that provide fast, accurate measurements of small-value inductors and Equivalent Series Resistance (ESR). What's more, ADI's single-chip solutions for impedance measurement simplify designs for chemical analysis and inductance-based proximity detectors.
Insulation Tester ("Megger"): ADI offers many solutions for insulation testers. Our portfolio of high-resolution ADCs, current-sensing amplifiers, precision, FET-input amplifiers, and low-leakage, high-voltage switches enables you to minimize power and size without compromising accuracy. In addition, ADI offers a family of Cortex™-M3-based single-chip solutions incorporating high resolution ADCs suitable for a variety of handheld and portable applications.
