Multiplying digital-to-analog converters (MDACs) produce a (current) output signal that’s a product of the given reference voltage and the code (i.e., a string of 0s and 1s) flowing through it. All data converters require a voltage reference (VREF) and a typical, standard DAC needs a very stable fixed reference voltage in order to operate properly. […]

Low-power piezo vibrator brings annunciation to wearable devices
Murata Americas today introduced the PJFV series. This miniaturized, low power consuming product leverages piezoelectric ceramics to provide vibration notifications and announcements to wearable devices. It measures just 10.5mm ´ 3.8mm ´ 2mm, has a rated working voltage of 3V, and current consumption of 2mA rms. Light and sound sensing products have historically been used for notification and announcement functions. With the roll-out of the PJFV series, now vibration solutions can […]
16-channel, 12/16-bit DACs target telecom optical-module control
Analog Devices, Inc. announced today a pair of highly integrated 16-channel digital-to-analog (D/A) converters that significantly reduce the system footprint for wired telecommunications systems, yet without any performance compromise. The 12-bit AD5767 and 16-bit AD5766 are fully integrated devices with all the required bias ranges for coherent optical systems of medium- to long-haul, fiber-based telecommunication […]
Low-jitter, low-power clock chips target coin-cell battery operated IoT sensors
SiTime Corporation introduced the SiT1569 oscillator and SiT1576 Super-TCXO with expanded frequency range. These unique timing solutions, available in a tiny CSP (chip-scale package), enable coin-cell battery operated IoT sensors to run up to 10 years. By using SiTime’s revolutionary TempFlat™ MEMS and mixed-signal technology, these devices deliver increased timekeeping accuracy and system power savings. The ultra-reliable, low-jitter SiT1576 and […]
Selecting an optocoupler to isolate a PWM
An optocoupler (or optoisolator) is a device that galvanically separates circuits and is not only great at isolation but allows you to interface to circuits with different ground planes or that operate at different voltage levels. Optocouplers are “fail safe” in that if subjected to voltages higher than the maximum rating, they are known to […]
Design software facilitates chip/package/board development efforts
Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced the Cadence® Virtuoso® System Design Platform, a formal, streamlined and automated co-design and verification flow between the Cadence Virtuoso platform and Allegro® and Sigrity™ technologies. This higher level of integration enables engineers to design concurrently across the chip, package and board. By automating what has until now been a manual process, the Virtuoso […]

Piezoelectric sounder puts out 100 dB to alert vehicle drivers
Murata Americas has introduced the PKMCS1818E20A0-R surface mount piezoelectric sounder for automotive applications that enables reflow mounting as an effective countermeasure against irregular mounting and abnormal sound. The product has a sound pressure level of 100 dB at 100mm and measures a diminutive 18 x 18 x 8 mm. Its wide operational temperature range means that it can operate in automobile cabin temperatures […]

Are your op amps pumped?
I was recently thinking about the issues surrounding rail to rail input opamps and the problems of making them low distortion – a problem I have had to overcome when designing integrated circuits for instrumentation applications. Some rail to rail opamps use two input stages – one using NMOS input transistors, the other using PMOS […]
