A precision rectifier, sometimes called a super diode, is an op amp circuit designed to behave like an ideal diode and is used in high-precision signal processing applications. It’s not a synchronous rectifier. The op-amp-based precision rectifier should not be confused with power MOSFET-based synchronous rectification. Because there is no diode voltage drop between the […]

What is PSRR and why is it important in op amps and LDOs?
The power supply rejection ratio (PSRR) describes the ability of a circuit to suppress any power supply variations from passing to its output signal and is typically measured in dB. It’s most often used with operational amplifiers (op amps), dc/dc converters, linear regulators, and low drop out regulators (LDOs). For op amps, the PSRR describes […]
Medical PCB assembly: Know these regulations and standards
by Ken Ghadia, Sales Engineer, TechnoTronix The reliability and safety of Medical PCB assembly are of utmost importance as they directly impact human healthcare. It is one of the most critical applications that demand the best PCB performance. Setting stringent regulatory standards is compulsory in medical device manufacturing. The standards also apply to the printed circuit […]

JFETs, diodes, voltage-controlled resistors now in DFN packages
Linear Integrated Systems, Inc. announced it has expanded its product line to include the availability of key, high-performance discrete small-signal parts in Dual-Flat No-Leads packages (DFN). This package has a reduced circuit board footprint, enabling designers who had previously used SOT-23 packaged parts to meet the demands of space-sensitive applications. Because the DFN has no […]
Chip resistors are AEC qualified
Electronics that require high reliability are no longer confined to military, aerospace, medical, or automotive market sectors. Many types of electronic end products now demand the higher reliability provided by automotive-grade resistors. Automotive-grade resistors offer increased reliability without the high cost of established reliability Mil-Standard products which allows engineers to increase the reliability of their […]
