Are your op amps pumped?
I was recently thinking about the issues surrounding rail to rail input opamps and the problems of making them low distortion – a problem I have had to overcome when designing integrated circuits for instrumentation applications. Some rail to rail opamps use two input stages – one using NMOS input transistors, the other using PMOS […]
50 Mbps RS-485 transceivers with failsafe for common real-world faults
Analog Devices, Inc. today announced the availability of two 50 Mbps RS-485/RS-422 transceivers for use in harsh environments including industrial automation, motor control, military and avionics. The ADM3065E and ADM3066E transceivers combine IEC61000-4-2 Level 4 electrostatic discharge (ESD) protection, high-speed data communication, support of 1.8 VIO logic (ADM3066E), and an industrial temperature range all in […]
Diff amp delivers 15 dB gain to 1.4 GHz
Analog Devices, Inc. announces the LTC6432-15, a wideband fully differential amplifier with 15dB gain, offering linearity of up to +50.3dBm OIP3 (output third-order intercept), very high OP1dB (output 1dB compression point) of +22.7dBm, and 3.2dB noise figure at 150MHz. In addition to its outstanding signal-to-noise at high frequencies, it maintains its dynamic range performance even […]
SMD three-axis MEMS accelerometers target industrial uses
Murata Americas announced the availability of the SCA3300 series high performance 3 axis MEMS accelerometers aimed at a broad range of industrial and automotive applications. Measuring just 7.6 x 8.6 x 3.3mm, this small surface mount sensor offers several measurement ranges of 1.5, 3, or 6g and features lower than 10mg offset stability. The series delivers best-in-class MEMS sensor characteristics with a non-linearity of 0.1 percent […]
Unity gain amplifier or voltage follower in a voltage divider
A voltage follower is also known as a unity gain amplifier, a voltage buffer, or an isolation amplifier. In a voltage follower circuit, the output voltage is equal to the input voltage; thus, it has a gain of one (unity) and does not amplify the incoming signal. The voltage follower does not need any external […]
MOS capacitors span dc to 20 GHz range
AVX Corporation has released new MS Series metal oxide semiconductor (MOS) capacitors for applications in the RF, microwave, and gigahertz ranges. Designed for DC to 20GHz operation in hybrid circuits, bias networks, receiver optical subassemblies (ROSA), transmission optical subassemblies (TOSA), and aerospace and test and measurement equipment, MS Series MOS single-layer capacitors use silicon dioxide (SiO2) […]
How do RFID tags and reader antennas work?
By Anil Pandey RFID — Radio-Frequency Identification — provides a unique identifier for that object and just as a bar code or magnetic strip the RFID device must be scanned to retrieve the identifying information. An RFID system has three parts: A scanning antenna A transceiver with a decoder to interpret the data A transponder […]
Wideband RF synthesizers operate at 53.125 MHz to 13.6 GHz with zero gaps in frequency coverage
Analog Devices, Inc. announced the ADF5356, a 13.6 GHz next-generation wideband synthesizer with integrated voltage-controlled oscillator (VCO) which targets applications such as wireless infrastructure, microwave point-to-point links, electronic test and measurement, and satellite terminals. A complimentary synthesizer product, the ADF4356, operates to 6.8 GHz and is comparable in performance. The ADF5356 generates RF outputs from 53.125 […]
