    Designing tiny microphone circuits with the industry’s smallest op amp

    Voice commands are a popular feature in many applications as a way to differentiate products in the market. Microphones are a primary component to any voice- or speech-based system and electret microphones are a common choice in applications for their small size, cost and performance. This blog post continues our series on high-performance, cost...

    These are not your grandfather’s TVS diodes

    Conventional transient voltage suppression (TVS) diodes have been essential building blocks in system designs for decades. They protect against transient surge events, and many designers rely on TVS diodes to provide an adequate level of surge immuni...

    Are you cooking up a new circuit? We can help!

    To accelerate the design process, we have developed something new call Analog Engineer’s Circuits. They are in a "recipe" format that includes step-by-step instructions, basic formulas, schematic diagrams and SPICE simulations. While each circuit is available as a standalone document, we’ve also compiled these “recipes”...

    How to HART-enable your analog input module

    The Internet of things (IoT) has implications for Industry 4.0, motivating smart sensor transmitters and similarly capable programmable logic controller (PLC) analog input modules. A previous blog post illustrated how to achieve digital communication...

    How to select the right USB Type-C™ signal switches

    USB Type-C™ enables the transfer of data, video and power over a single cable and connector. The flip-ability of the USB Type-C connector introduces connection pin redundancy, which requires a signal switch in order to bring the correct data path to the central processing unit (CPU) for signal processing. There are two types of signal switches...

    Does your design have a low talker?

    Many of you can relate to having a conversation with a “low talker” – someone whose ultra-low voice makes them difficult to understand. Communicating with a low talker often leads to miscommunication and mixed signals, illustrated to great effect in a well-known sitcom from the 1990s . So what does a low talker have to do with electronic...

    LIN: take a look inside

    Did you know that drivers, passengers and even cargo can often benefit from up to 80 separate LIN modules placed throughout vehicles? These modules help implement a wide range of features that many of us use multiple times daily, without truly unders...

    Transients in 24V automobiles

    Automobiles are becoming more advanced every day. The number of integrated circuits (ICs) is increasing every year and spreading to more modules within the automobile to control lights, heating, sensors and more. The new paradigm of designing automob...

    ESD fundamentals, part 5: reverse working voltage, breakdown voltage and polarity configuration

    We’ve covered a lot of material in this electrostatic discharge (ESD) fundamentals series, such as the International Electrotechnical Commission (IEC) 61000-4-2 rating , the ESD clamping voltage and junction capacitance . In this final installment of the series, I’ll cover a few more important ESD parameters: reverse working voltage, breakdown...

    The HART of field transmitters

    In a previous blog post , my colleague Gavin Bakshi discussed the highway addressable remote transducer (HART) protocol and its place in sensor transmitter designs. To recap, simple transmitter designs traditionally communicate an analog value, typically referred to as the process variable (PV), through a current loop. This PV is generally tied to a...
