Perhaps you have a quad pack of op amps, are using only three, and need a single comparator. It might be tempting to use the remaining op amp as a comparator, after all, both have high gain, low offset, and high common-mode rejection. But it’s easier said than done, because a comparator and an op […]

Isolated RS-485 µModule transceiver meets medical IEC 60601-1 requirements
Linear Technology Corporation introduces the LTM2885, an isolated RS485 µModule® transceiver for guarding against large ground-to-ground differentials. Many industrial, utility, medical, military, and intrinsic safety applications require isolation components with increased voltage and spatial separation for human safety. The LTM2885 provides 6500VRMS reinforced isolation between the logic level interface and the transceiver bus pins, far […]
16-V CMOS Analog comparators boast 5 µA ave. current/comparator
STMicroelectronics has upgraded its 16V CMOS dual and quad analog comparators using the latest-generation process technology to achieve lower typical current consumption of 5µA per comparator, as well as faster propagation time and increased ESD capability of up to 4kV. Compatible with the previous-generation ICs, the TSX393, TSX339, TSX3702, and TSX3704 further extend the performance […]
Why do industrial sensors measure in 4-20mA to programmable logic controllers?
A large number of sensors that take in and translate data from the real world into electrical signals are analog sensors, and if listed as digital sensors, it’s because they have integrated analog-to-digital converters. Traditionally, wired sensors have altered an electrical current in response to environmental conditions. Sensors range from familiar examples like photodiodes and […]
Wireless modules feature secure Bluetooth, dual-band 802.11ac Wave 2 Wi-Fi with 2×2 MU-MIMO

General tips for preventing problems in analog circuits
Tips for preventing problems could fill a book, especially if every professor, technician, or engineer were to contribute tricks and tips that they have learned over the years. However, many will agree that an ounce of prevention is worth a pound of cure. Here, we present a few general tips that may seem obvious to […]
Cellular module integrates LTE Category 1 modem and GNSS engine
u-blox (SIX:UBXN), a global leader in wireless and positioning modules and chips, today announced the LARA-R3121, a new module comprising a single mode LTE Category 1 modem and a GNSS (Global Navigation Satellite System) positioning engine specifically designed for IoT and M2M devices. LTE modem, GNSS and module technology were all developed in-house at u-blox. […]
AFE simplifies complex programming algorithms, extends life of industrial equipment
Analog Devices, Inc. introduced a highly integrated polyphase analog front end (AFE) with power quality analysis designed to help extend the health and life of industrial equipment while saving developers significant time and cost over custom solutions. Achieving extremely accurate, high-performance power quality monitoring typically requires customized development, which can be expensive and time-consuming. The […]
What’s the difference between instrumentation and precision amplifiers?
Instrumentation amplifiers (INAs) are precision devices, but they have a particular function and aren’t another type of operational amplifier (op amp). Instrumentation amplifiers are not op amps; you can’t configure them in a multitude of ways, and you only set gain to a chosen value, and only within a specified range. So op amps are […]
