45 V, Zero-Drift Op Amp Provides 
On-Chip EMI Filtering

Microchip Technology has announced the MCP6V51 zero-drift operational amplifier (op amp). The new device provides ultra-high-precision measurement while minimizing the increasing influence of high-frequency interference by offering a wide operating range and on-chip electromagnetic interference (EMI) filters. The growth of industrial control and factory automation has led to an uptick in the number of sensors that need to be monitored, and the MCP6V51 amplifier is designed to provide accurate, stable data from a variety of sensors.
The self-correcting zero-drift architecture of the MCP6V51 enables ultra-high Direct Current (DC) precision, providing a maximum offset of ±15 microvolts (µV) and only ±36 nanovolts per degree Celsius (nV/°C) of maximum offset drift. Well suited for for applications such as factory automation, process control and building automation, the MCP6V51 also supports a wide operating voltage range, from 4.5 V to 45 V.

Tiny PMICs Offer Efficient High Voltage Automotive Solutions

Maxim Integrated Products has announced power-management ICs (PMICs) that the company claims offer the industry's smallest solution size and highest efficiency. MAX20004/6/8, MAX20034 and MAX20098 offer low quiescent current, improved noise performance and electromagnetic interference (EMI) mitigation for digital instrument clusters and radio head units.
Maxim's array of automotive-grade ICs provides many options to manage the DC power as automotive OEMs transition from processors that consume 20 W of power to artificial intelligence platforms that consume as much as 500 W. With a package size of 3.5 mm x 3.75 mm, these buck converters are the smallest solution size in industry, Maxim. The devices' flip-chip quad-flat no-leads (FCQFN) packaging reduces high-frequency switch node ringing and eliminates bond wires to lower MOSFET switch on-resistance and increase efficiency. 



Cutting-Edge Embedded Vision Solutions

4:1 Input DC-DC Converters Boast 1" x 1" Footprint
    
RECOM has released its REC15E-Z series of 15 W isolated DC-DC converters that featured wide input ranges at low cost in the popular 1"x1" case size. This saves a significant amount of PCB space, while the wide input ranges increase flexibility by accepting several standard bus voltages. The REC15E-Z DC-DC converters are fully-specified devices with 15 W, no minimum load, 1,600 VDC isolation, high efficiency up to 90% and low ripple/noise. The REC15E-Z series was designed for cost-sensitive applications where board space is at a premium. The wide 4:1 input ranges accept 9 V to 36 V or 18 V to 75 V to cover multiple supply options such as lead-acid or lithium batteries or 12/24/36/48 V industrial bus voltages.

The inputs are protected against transients of up to 100 V and feature undervoltage-lockout (UVLO) to protect batteries from being over-discharged. The single or dual outputs are continuously protected against short circuit and overload conditions and can drive high-capacitive loads. They are fully certified to industrial EMC and safety standards and come with a three-year warranty.
