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 […]

Notch filters boast built-in ESD protection function
TDK Corporation announces the release of its newly developed AVRF041A150MT242 and AVRF061D2R4ST532 notch filters with ESD protection function. Volume production of these devices will begin in March 2022. The new notch filters are compliant with the IEC61000-4-2 Level 4 immunity standard. They are well suited to ensuring EMC requirements are met in the audio circuits […]
N-channel JFET switch replaces discontinued NXP/philips BF510 devices
Linear Integrated Systems, Inc. announced it has released a direct, pin-for-pin replacement for the Philips/NXP BF510. Per an NXP discontinuation notice published in June 2020, this part is no longer manufactured or supplied by NXP. The new Linear Systems’ LSBF510 is an N-Channel Single JFET for applications up the VHF range. The part’s features are: […]
Infineon’s latest class D audio module delivers higher output power, smaller footprint
Class D audio power amplifiers offer a combination of small size, low heat dissipation, high integration, and excellent sound quality. Unlocking the potential of its best-in-class power MOSFET technology, Infineon Technologies AG introduces the MERUS 2-channel, analog input, class D audio amplifier multichip module (MCM) MA5332MS. It is a powerful upgrade to its predecessor, offering the same […]
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 […]
Evaluation board helps check out SMD oscillators, VCXOs, TCXO/VCTCXOs
The desire to be able to test oscillators quickly and easily is more than achievable using the IOSC EVBoard. The evaluation board is suitable for measuring most surface mount standard oscillators, VCXOs, or TCXO/VCTCXOs. It is available from IQD, part of the Würth Elektronik eiSos Group, and a selection of distributors. The IOSC EVBoard comes […]

AVX Corporation released the new TCO Series high-temperature, automotive-grade polymer chip capacitors, which are rated for operating temperatures up to 150°C at category voltage and meet AEC-Q200 Stress Test Qualification for Passive Components requirements, which ensure stable performance at 85°C, 85% relative humidity, and rated voltage for up to 1,000 hours. Based on AVX’s field-proven TCQ Series automotive […]
Small nichrome chip resistors handle 0.05 W
As design engineers continue to push the miniaturization of electronic devices while maintaining or increasing functionality, there is a corresponding need for smaller and more precise electronic components, such as chip resistors. If a precision application requires both small size and high-power handling, finding suitable precision resistors may be challenging. Stackpole recently increased the power […]
