Dual channel, multi-purpose power amplifier IC - Apex Microtechnology

Designed with power density in mind, the PA166 comes equipped with a pair of high voltage MOSFET operational amplifiers with monolithic cores.

In a surface mount package and with a body of just 20 x 20mm, each channel is designed for operation up to 205V while providing 1A of continuous current.

Internal PCB layout features exceptional channel separation of 80dB, while optional separate supplies for the amplifier core and output stage allow for optimized voltage swing with an overall power dissipation of 28W.

The PA166 comes equipped with several safety features for system protection, including temperature compensated current limit, an over-current flag, and an output disable function.

To support rapid prototyping and device evaluation, Apex offers the EK87 evaluation kit.

New spread spectrum oscillator offers low-EMI drop-in replacement - EuroQuartz

Euroquartz has a new spread spectrum oscillator. Offering customers a drop-in replacement for standard clock oscillators with a reduction in electromagnetic interference (EMI) by as much as 12dB.

The most efficient method to reduce EMI is to suppress it at the source and Euroquartz’s new EQHM22 does exactly that. Compared with conventional clock oscillators, spread spectrum (dithered) oscillators can reduce EMI by up to 12dB and the parts are drop-in replacements for standard components. So there is no requirement to redesign existing PCBs.

Offering a choice of modulation rates and spreads, these new devices offer frequencies from 16 to 40MHz in a miniature surface mount package measuring 2.5 x 2.0 x 0.9mm.

Frequency stability is available as low as ±25ppm in both commercial (0 to 70°C) and industrial (-40 to +85°C) grades with available input voltages of 1.8, 2.5 and 3.3V DC, all ±10%. Output logic is CMOS with a load capability of 15pF.
