Features, functions and application scope of power amplifier ax508
Axiom’s ax508 power amplifier (PA) adopts mainstream CMOS technology and integrates four band GSM / GPRS functions on a single integrated circuit (IC). Compared with the company’s ax502 products, ax508’s main advantages are higher power and longer talk time. Axiom’s ax508 places the PA in an ultra small lead frame package with a size of […]
Main characteristics and application range of zero drift operational amplifier lmp2021 / 2
The two zero drift operational amplifiers produced by NS not only have the lowest input voltage noise in the industry (the input noise is as low as 11nv / sqrthz when operating at 1000V / V gain times), but also have high accuracy when operating at DC voltage. They are most suitable for sensor interface […]
How to set bias voltage of operational amplifier
When the dual power supply operational amplifier is connected to a single power supply circuit, engineers will encounter some dilemmas in setting the bias voltage, such as whether the bias DC voltage is better to be divided by resistance or connected to a reference voltage source? Some netizens suggested using a reference voltage source because […]
Design of high speed CMOS Fully differential operational amplifier with folded cascode structure
“With the wide application of digital to analog converter (DAC) and analog to digital converter (ADC), high speed operational amplifier, as its core component, has attracted more and more attention and research. Speed and accuracy are two important indexes of analog integrated circuits. However, the improvement of speed depends on the unity gain bandwidth and […]
Function characteristics and application range of PWM Buck DC / DC converter lt3507
For automotive applications, the lt3507 has the lowest 4V input voltage, which enables it to meet the low input voltage requirements in the case of cold start. Similarly, its 36 V input capability enables the device to withstand the common transients in case of sudden load drop. The lt3507’s 250kHz to 2.5MHz switching frequency is […]
Selection and design of stepping motor
The structure principle of the marine compass simulator is: the rotation of the steering wheel causes the change of the ship’s course, and also causes the change of the compass reading. When the required rotation angle of compass simulator is too large, frequency conversion rotation method is used to overcome the disadvantage of too long […]
The beta version of switch simulator has been released
In the past few years, Yuzu emulator, the leader of switch emulator, has been constantly updated to improve performance, accuracy and the number of games supported. The latest update is worth mentioning. The team said that by refactoring the memory manager code, the memory occupied by the simulator was reduced by as much as 50%. […]
