Cryptography tool protects products and integrates with 1-Wire
Analog Devices, Inc. introduced the DS28E30 1-Wire ECDSA Secure Authenticator, a cost-effective solution to detect and help protect products from counterfeiting or misuse. Combining a fixed-function cryptographic toolbox based on the industry-standard FIPS 186 elliptic curve digital signature algorithm (ECDSA), secure storage of keys and application data, and the single-contact 1-Wire interface, the device easily […]
Oven-controlled Xtal oscillators sync to 1 pps input, output
IQD launched the IQCM-200, a disciplined OCXO, incorporating sync to a 1 PPS (pulse per second) input as well as a 1 PPS output. The IQCM-200 is part of a series of disciplined OCXOs available from IQD. This particular model is the smallest sized OCXO capable of achieving a holdover capability of 1.5µs over 24 […]
What’s the difference between equalizers?
Equalizers are used to alter the performance of signal chains. In some cases, that means linearizing signal chain performance. In other cases, equalizers are used to introduce nonlinearities. As a result, equalizer designs vary widely from simple passive circuits to complex multi-stage designs and active circuits. This FAQ reviews equalizer basics, looks at equalizers for […]
How does a precision rectifier work?
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’s a logarithmic resistor ladder good for?
A logarithmic resistor ladder consists of a resistor string and switches designed to attenuate a signal. The state of the switches can be considered to represent a digital code proportional to the logarithm of the attenuation ratio. Logarithmic attenuation is useful when a large dynamic range is needed. Audio volume control and fading/balancing audio signals […]
Discrete diodes feature super-small package size/footprint
ROHM Semiconductor announced the addition of 14 new models to their PMDE package (2.5mm × 1.3mm) lineup – meeting the requirements for smaller protection and switching circuits (RBxx8 Series, RFN Series, VS Series). Diodes are used for rectification, protection, and switching circuits in a wide range of applications such as automotive, industrial, and consumer fields. Additionally, there […]
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 […]
MLCCs handle 150℃ for automotive apps
Samsung Electro-Mechanics announced on the 11th that it has developed 13 types of automotive MLCCs with guaranteed use in a 150℃ environment with plans to supply them to global auto parts manufacturers. High-reliability automotive MLCCs with guaranteed use at 150℃ have been produced only by some companies, but with this development, Samsung Electro-Mechanics will step up […]
