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 […]
ADC resolution, accuracy, repeatability, and throughput
Here, we review some common specifications for successive approximation register (SAR) and sigma delta analog to digital converters (ADCs.) For converters, resolution is the number of bits per conversion cycle that the converter is capable of processing. For example, a converter with 12 bits of resolution is often referred to as “12 bits wide,” since […]

SAR 16-bit ADC digitizes up to up to 750 kHz
Linear Technology Corporation introduces the LTC2320-16, a 16-bit 1.5Msps per channel, no latency successive approximation register (SAR) ADC with eight simultaneously sampling channels supporting a rail-to-rail input common mode range. The LTC2320-16 features a flexible analog front end that accepts fully differential, unipolar or bipolar analog input signals, as well as arbitrary input signals, and […]
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 […]
Low power AFE targets wearable devices
Analog Devices, Inc. today announced a low power, next-generation biopotential analog front end (AFE) which enables smaller, lighter, and less obtrusive cardiac monitoring devices with longer battery life. The AD8233 AFE is a fully integrated, single-lead electrocardiogram (ECG) front end designed in one compact, easy-to-use component. Typically, developers need to design ECG front ends from […]
Sigma Delta ADC vs. SAR vs. Pipeline: How to Choose
Assuming that you are familiar with the fundamental specifications of an ADC and what they mean, the next step is to know your entire signal chain well and then work to fit the ADC to the requirements. After carefully determining signal chain requirements, then select your ADC with the understanding that if the ADC is […]
DAC offers high resolution with low component count for diverse applications
Analog Devices, Inc. today introduced the AD9164 D/A converter that brings high-resolution radar images for designers of military and commercial radar while reducing solution component count. Additionally, for designers of precision instrumentation equipment, such as smartphone testers, the new device ensures improved accuracy as well as speed of test, contributing to faster market-ready time while […]
32-Bit SAR ADC with digitally filtered, 1-Msps no-latency outputs
Linear Technology Corporation introduces the LTC2508-32, an ultrahigh precision 32-bit successive approximation register (SAR) analog-to-digital converter (ADC). Many high performance applications, including data acquisition, industrial control and medical instrumentation, require both accuracy and speed. This is often achieved by using a high resolution delta-sigma ADC and a high speed SAR ADC in the same system. […]
