Analogue and Discretes

At Hifideluxe in Munich next month, Rohm will be pre-viewing an audio DAC claimed to have a 131.6dB signal-to-noise ratio. Called BD34301EKV it is a 32bit, two channel ΣΔ converter with -115dB THD+N, taking inputs as 2.8 / 5.6 / 11.2 / 22.4MHz DSD or 32kHz to 768kHz PCM (pulse-code modulation) – DSD is direct stream digital, a Sony-Philips pulse-density ...

Microchip is aiming at factory automation with a ‘zero-drift’ operational amplifier that will run from 45V and includes on-chip EMI (electromagnetic interference) filters. Called MCP6V51, it has a gain-bandwidth product of 2MHz and a self-correcting architecture that  provides a maximum offset of ±15µV and ±36nV/°C maximum offset drift. Operating range is 4.5V to 45V, with a maximum quiescent current of ...

Analogue capability and security functions in the Renesas Synergy S1JA microcontroller, target sensor signal acquisition and conditioning to simplify industrial instrumentation, multi-sensory systems and single-phase electrical meters, says RS Components. The low power microcontroller is based on a 48MHz Arm Cortex-M23 processor core with 256kb code flash and 32kb SRAM. There is also an integrated 16-bit ADC, 24-bit sigma-delta ADC, 12-bit DAC, op amps, ...

Mouser stocks the ADIS1647x precision industrial inertial measurement units (IMUs) from Analog Devices.  The IMUs can be used in virtual reality (VR) and augmented reality (AR) devices, as well as for navigation in unmanned aerial vehicles (UAVs), autonomous vehicles, smart agricultural equipment as well as industrial and IoT devices. The IMUs deliver six degrees of freedom sensing, using triple-axis MEMS-based gyroscopes and ...

Schaffner is claiming to have created a milestone in three-phase filtering with “the most compact and most modern solution in the market today”. And then it said: “these filters are based on a new design structure, resulting in a significant footprint reduction and have their connection terminals integrated within the filter enclosure.” And then it didn’t provide any dimensions. But ...

Aiming at on-board battery chargers, Vishay has released a family of high-voltage thyristors and diodes qualified to AEC-Q101. There are 37 all together, in three packages: surface-mount DPAK (TO-252AA) surface-mount D²PAK (TO-263AB) through-hole TO-247AD The nine thyristors deliver continuous on-state current from 12 to 79A rms, while the diodes, both standard and fast recovery types, offer forward current from 8 to ...

At Embedded World 2018, we caught up with Stefan Steyerl of Analog Devices.

Microchip’s MCP6411 operational amplifier can operate with a single supply voltage as low as 1.7V, while drawing 55μA quiescent current (max). Called MCP6411, input offset is ±1.0mV max, and both input and output operate rail-to-rail. Compensation means it is unity gain stable, and it has a gain bandwidth product of 1 MHz (typ). “The MCP6411 has enhanced EMI protection to ...

Toshiba Electronics Europe has added a 45W (4Ω load) four-channel audio power amplifier to its in-car entertainment range. TCB001FNG is based upon a complementary MOS process with n and p-channel DMOS fets. Supply can vary across 6 to 18V, allowing operation while the engine is idling or cranking. “The product includes functions to detect and prevent abnormal noise with Toshiba’s ...

The  LTC7815 Power-By-Linear IC is a  high frequency (up to 2.25MHz) triple output (buck, buck, boost), synchronous DC/DC controller that maintains all output voltages in regulation during automotive cold crank conditions. A 12V automotive battery can droop to less than 4 volts during engine restart or cold crank, causing reset of infotainment systems and other electronics that operate from 5 ...
