ROHM has launched a new branding “MUS-IC” reflecting ROHM’s focus on solutions for high-fidelity audio products. This branding covers a range of D/A converter ICs (DAC ICs), optimized for high-fidelity reproduction, and power supply products. The increased adoption of high-resolution audio sources has lately strengthened the demand for audio equipment that can deliver an appropriate sound […]

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. […]
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 […]

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 specs: 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 […]
