Operational amplifiers are used in many configurations and with many variations on specifications, depending upon the application. However, an IC package of operational amplifiers will often come with several in a package (e.g., a “quad pack” will have four op amps). If you have leftover, unused op amps on the same chip, the unused ones […]

Electrostatic discharge and analog circuits: Preventing the undetectable disaster
Analog circuits are exposed to outside influences most often through input channels by way of op amps acting as filters, buffers, or amplifiers. Electrostatic discharge (ESD) results from the direct contact of two things that are at different voltage potential levels and can also be defined as a fast, high current transfer. Analog circuit exposure […]
What is a CODEC?
In the embedded hardware world, the term CODEC stands for COder/DECoder and is basically an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) in one package. A codec, whether hardware or emulated in software, converts analog audio signals into digital signals for transmission or encodes them for storage in a digital format. Later, the decoder […]
High-resolution, low-power SAR ADC lengthen operating time of instrumentation
Analog Devices today announced a new generation of high-precision successive-approximation (SAR) analog-to-digital converters (ADCs) that uniquely combine the attributes of high performance, low power, small footprint, and ease of use. These ICs enable mobile test and measurement instruments to operate for longer duration during field tests while improving measurement accuracy and repeatability. The new devices […]
