ture during operation or long-term storage may be a concern. They have very low noise of less than -25 dB and a low voltage coefficient of 0.5 ppm/V. The resistors are in M55342 case sizes from 01 to 12, with power ratings from 50 mW to 1W, working voltages from 40V to 200V, and resistance ranges from 49.9Ω to 3.3 MΩ depending on tolerance. Intertechnology, www.vishay.com/resistors-linear/ military-qpl-mil/ Vishay  1.5-A POL DC-DC converters Murata has added a miniature 1.5A SIP model to its OKR family of non-isolated point-of-load converters. The OKR-T/1.5-W12-C is a SIP packaged, through-hole mounted miniature device with wide input voltage range and programmable output voltage. Based on 600 kHz synchronous buck topology, the OKRT/1.5-W12-C offers power conversion efficiencies of 93% and also has the ability to drive up to 200 µF ceramic capacitive loads. Output voltage is programmable from 0.591 to 6.0 VDC from an input voltage range of 4.5 to 14 VDC. With good derating performance and other design features including over temperature and over current protection, remote On/Off control, and under voltage lock out (UVLO), dimensions are 10.4 x 10.16 x 6.1 mm and temperature range is – 40 to + 85 degrees C. The units meet UL/EN/EC 60950-1 safety and FCC EMI/RFI emission limits. Murata Power Solutions, www.murata.eu 3 to 20A DC-DC converters  Dual, 16-bit ADC/clock jitter cleaner Texas Instruments has introduced a pair of devices today supporting the JEDEC JESD204B serial interface standard for data converters. The ADS42JB69 is a dual-channel, 250 MSPS 16-bit ADC. The LMK04828 is a clock jitter cleaner and is the first to support JESD204B clocking. For designs requiring a traditional parallel interface, TI also has the ADS42LB69 16-bit ADC at 250 MSPS, with an LVDS interface. JESD204B is an industry-standard serial communications link that simplifies the digital data interface between data converters and other devices, such as FPGAs, DSPs and ASICs. The ADS42JB69 is the only 16-bit ADC incorporating all three JESD204B subclasses, 0, 1 and 2, allowing multi-device synchronisation between data converters. At 170 MHz intermediate frequency (IF), both ADCs provide SFDR performance of 89 dBc, and SFDR of 100 dBc, excluding HD2 and HD3; SNR of up to 74.9 dB relative to full scale (dBFS) and channel isolation of 100 dB. 100-fsec RMS jitter (10 kHz to 20 MHz) at 245.76 MHz is possible using a low-noise voltage-controlled crystal oscillator module. Texas  Automotive-qualified linear regulators Micrel has announced two AEC-Q100 qualified, highperformance linear regulators. The MAQ5281/82 family offers a very wide input operation voltage range of 6 to 120V DC, and supplies an output current of up to 25 mA or 50 mA. They have a quiescent current of 6µA typical, an adjustable output from 1.27V to 5.5V and feature high PSRR of over 90dB. Other features include a high output accuracy of (+/- is the single symbol, + over -), thermal shutdown and current limit protection. The devices come in an 8-pin ePad MSOP package, are available in volume, and pricing starts at $1.00/$1.05 (1000).  TDK-Lambda’s iCF (3A/16.5W), iCG(6A/33W), iBF (12A/66W) and iAF (20A/110W) series of nonisolated SMT DC-DC converters comply with the latest 2nd Generation DOSA standards for Point-of-Load (PoL) converters. Features include: high power densities and no external tuning components. All operate with input voltage range of 4.5V to 14V and have adjustable conversion efficiencies up to 94.5%. These miniature 2nd Generation DOSA DC-DC converters range in size from 12.2 x 12.2 x 4.45 mm (less than 0.5 square inch) to 33 x 13.46 x 7.75 mm. Optional EPC (Edge Plated Castellation) layout is also available. They can operate in ambient temperatures from -40°C up to +115°C, and use a constant switching frequency of 600kHz, which provides a low noise profile and simple EMI filtering. All models are safety approved to UL/CSA60950-1 and VDE CB scheme per IEC/ EN60950-1. TDK-Lambda, Micrel, www.micrel.com/_PDF/MAQ5281.pdf Go to www.edn-europe.com for continuously-updated coverage of new product and technology introductions.
