There are many parameters which define the performance of analog and mixed-signal circuits. Among the many “static” (sometimes called “DC” specifications, but this is a misnomer) factors are offset error, gain error, integral nonlinearity, and differential nonlinearity. Note that there are also dynamic specifications (called “AC” specifications but also a misnomer) such as the effective […]

What is a multiplying DAC?
Multiplying digital-to-analog converters (MDACs) produce a (current) output signal that’s a product of the given reference voltage and the code (i.e., a string of 0s and 1s) flowing through it. All data converters require a voltage reference (VREF) and a typical, standard DAC needs a very stable fixed reference voltage in order to operate properly. […]
16-channel, 12/16-bit DACs target telecom optical-module control
Analog Devices, Inc. announced today a pair of highly integrated 16-channel digital-to-analog (D/A) converters that significantly reduce the system footprint for wired telecommunications systems, yet without any performance compromise. The 12-bit AD5767 and 16-bit AD5766 are fully integrated devices with all the required bias ranges for coherent optical systems of medium- to long-haul, fiber-based telecommunication […]
A/D converter supports IF sampling of signals up to 9 Ghz for 4G/5G basestations
As part of a new series of high-speed analog-to-digital converters (A/D converters), Analog Devices, Inc. (ADI) today introduced the AD9208. Engineered for gigahertz-bandwidth applications, this A/D converter meets the increased spectral efficiency demands of 4G/5G multi-band wireless communications base stations. It also meets the reduced run-time targets of multi-standard production instrumentation and provides greater detection […]

Then click the “Read more” link and follow the conversation on EDAboard.com or log in to EDAboard and participate in the analog IC forum threads.) Making gain positive and NF less than 7.0 dB – I have designed a mm-wave amplifier, as I intend to […]
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 […]
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 […]
