Why is unloaded buffer showing an offset? – I am using an AD8041 IC as a buffer for a 0.2 Vpp sinewave input at 1 kHz from the function generator. The circuit is set on an NI Elvis II+ board. The buffer is unloaded but there occurs some offset at the output of the buffer. […]
VCM vs VOUT plots for instrumentation amplifiers with two op amps
This article introduces the VCM vs. VOUT plot for an instrumentation amplifier with two operational amplifiers (op amps) and delivers a thorough treatment of this amplifier topology. Additionally, the internal node equations are derived and used to plot each internal amplifier’s input common-mode and output-swing limits as a function of the instrumentation amplifier’s common-mode voltage. […]

Amplifying DC voltage from 5V to 12V – I use an Arduino board with a 5V output supply but I Ineed to operate 12V motor. I know that I could connect the Arduino to a 12V power supply to solve the problem. But but I can’t do it for some of reason so I have to build […]
Electrometer-Grade Amplifier from Analog Devices
Analog Devices, Inc. today introduced an electrometer-grade operational amplifier that enables chemical analysis instruments to achieve the highest level of precision and data repeatability over a wider temperature range in a compact solution that reduces overall bill of materials and design footprint. The ADA4530-1 op amp achieves this with an input bias current that is […]

High-side switching using P channel – I am using LTC4412 for power path switching. In the example, it shows use of P Channel with drain connected to Positive and Source to load. I understand that this would avoid reverse flow but shouldn’t the voltage input be connected to Source of MOSFET? Read more I am trying the following […]
Coax bi-directional amps operate in L and S bands
Pasternack, a manufacturer and supplier of RF, microwave and millimeter wave products, introduces a new line of bi-directional amplifiers that are used for sending and receiving radio signals in key applications such as unmanned aerial vehicles (UAV), unmanned ground vehicles, L and S band radar, military radio, commercial air traffic control, weather and earth observation, satellites and […]
Coax GaN power amps span 30 MHz to 7.5 GHz
Pasternack, a leading manufacturer and supplier of RF, microwave and millimeter wave products, announces their expanded offering of gallium nitride (GaN) coaxial power amplifiers. GaN has emerged as the technology of choice in power amplifier designs. The high power density of gallium nitride semiconductor technology dissipates heat more effectively, which results in amplifier designs that […]
