Nyquist rate basics and sufficient sampling for ADCs
Converting a real-world (analog) signal into a digital signal means that you have to bring the signal into an Analog-to-Digital converter (ADC). From there, the ADC turns the continuous analog signal into a discrete, digital signal by sampling, or taking regular snapshots of, the curves of the analog signal. After sampling is complete, any information […]
Rutronik to distribute AVX product range
Rutronik Elektronische Bauelemente GmbH is now a global AVX distribution partner for AVX’s entire product range. The two companies have been partners in Europe since 1997. In 2015 they expanded the franchise to include Asia. Now, Rutronik is also a franchise distributor for AVX in the USA. “Rutronik is one of our longest and most […]
Varistors head off ESD in capacitance-sensitive apps
AVX Corporation has released the new Antenna PowerGuard Series varistors, an ultralow capacitance extension of its reliable AntennaGuard range with new voltage, capacitance, and energy ratings. Antenna PowerGuard Series varistors exhibit highcurrent and energy handling capabilities, low insertion loss, low leakage current, and unsurpassed reliability compared to diode options. These advantages, combined with AEC-Q200 qualification, bidirectional […]
Selecting an op amp
You could start with a similar op amp from a similar, known-good circuit or reference design and extrapolate from there. However, not everything labeled a reference design has actually been built and tested. But there’s another way to get organized and feel in control of the selection process. A methodical approach is outlined below that […]
Compensating for DAC offset and gain error
Digital-to-analog converters (DACs) are subject to gain and offset error. Errors can be compensated for with hardware by using external components or by trimming the DACs after they have been manufactured. Trimming is necessary because the error is caused by mismatched resistors; trimming attempts to change resistor values in the DAC. However, some DACs can […]
Clock management fanout buffer line expanded to seven new devices
Microsemi Corporation announced four new miClockBuffer products and three new miSmartBuffer products in its portfolio of clock management fanout buffers. The ZL40230, ZL30235 and ZL30240 miSmartBuffer and ZL40231, ZL40234, ZL40241 and ZL40260 miClockBufferdevices further expand Microsemi’s broad lineup of high performance products targeted to a variety of applications within the communications, data center and enterprise markets. The ZL40231, ZL40234, ZL40241 and ZL40260 provide customers with single-ended […]
Zero-drift op amp consumes just 1.3 μA
Analog Devices, Inc. announces the LTC2063 zero-drift op amp which draws just 1.3μA typ (2μA max) on a 1.8V supply. This micropower amplifier maintains uncompromised precision: maximum input offset voltage is 5μV at 25°C, maximum drift is 0.06μV/°C from –40°C to 125°C. Maximum input bias current is 15pA at 25°C, and 100pA from –40°C to […]
