Digital Multi Meters
ADI offers many solutions for portable and bench-top DMMs. Our portfolio of high-resolution ADCs, current-sensing amplifiers, low-resistance, high-voltage switches, and RMS-to-DC converters 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.
The ADG1419 is a monolithic iCMOS® device containing a single-pole/double-throw (SPDT) switch. An EN input on the LFCSP is used to enable or disable the device. When disabled, all channels are switched off.
The industrial CMOS (iCMOS) modular manufacturing process combines high voltage, complementary metal-oxide semiconductor (CMOS) and bipolar technologies. It enables the development of a wide range of high performance analog ICs capable of 33 V operation in a footprint that no other generation of high voltage parts has achieved. Unlike analog ICs using conventional CMOS processes, iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduced package size.
The on-resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. The iCMOS construction ensures ultralow power dissipation, making the part ideally suited for portable and battery-powered instruments.
Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG1419 exhibits break-before-make switching action for use in multiplexer applications.

The ADR43x series is a family of XFET voltage references featuring low noise, high accuracy, and low temperature drift performance. Using Analog Devices, Inc., patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, voltage change vs. temperature nonlinearity in the ADR43x is minimized.
The XFET references operate at lower current (800 µA) and supply headroom (2 V) than buried Zener references. Buried Zener references require more than 5 V headroom for operations. The ADR43x XFET references are the only low noise solutions for 5 V systems.
The ADR43x family has the capability to source up to 30 mA of output current and sink up to 20 mA. It also comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance.
The ADR43x is available in 8-lead MSOP and narrow SOIC packages. All versions are specified over the extended industrial temperature range of −40°C to +125°C.
