The short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter

The ADL5902 is a true rms responding power detector that hasa 65 dB measurement range when driven with a single-ended 50 ? source. This feature makes the ADL5902 frequencyversatile by eliminating the need for a balun or any other form of external input tuning for operation up to 9 GHz.The ADL5902 provides a solution in a variety of high frequencysystems requiring an accurate measurement of signal power. Requiring only a single supply of 5 V and a few capacitors, it is easy to use and capable of being driven single-ended or with abalun for differential input drive. The ADL5902 can operate from 50 MHz to 9 GHz and can accept inputs from ?62 dBm to at least +3 dBm with large crest factors, such as GSM, CDMA,W-CDMA, TD-SCDMA, WiMAX, and LTE modulated signals.The ADL5902 can determine the true power of a high frequency signal having a complex low frequency modulation envelope or can be used as a simple low frequency rmsvoltmeter. Used as a power measurement device, VOUT isconnected to VSET. The output is then proportional to thelogarithm of the rms value of the input. In other words, thereading is presented directly in decibels and is scaled 1.06 V per decade, or 53 mV/dB; other slopes are easily arranged. In controller mode, the voltage applied to VSET determines thepower level required at the input to null the deviation from the set point. The output buffer can provide high load currents.The ADL5902 has 1.5 mW power consumption when powereddown by a logic high applied to the PWDN pin. It powers up within approximately 5 ?s to its nominal operating current of 73 mA at 25?C. The ADL5902 is supplied in a 4 mm ? 4 mm,16-lead LFCSP for operation over the wide temperature rangeof ?40?C to +125?C.The ADL5902 is also pin-compatible with the AD8363, 50 dBdynamic range TruPwr? detector. This feature allows the designer to create one circuit layout for projects requiring different dynamic ranges. A fully populated RoHS-compliant evaluation board is available.Applications Power amplifier linearization/control loops Transmitter power controls Transmitter signal strength indication (TSSI) RF instrumentation

The ADP2138 and ADP2139 are high efficiency, low quiescent current, synchronous step-down dc-to-dc converters. The ADP2139 has the additional feature of an internal discharge switch. The total solution requires only three tiny external components. When the MODE pin is set high, the buck regulator operates in forced PWM mode, which provides low peak-to-peak ripple for power supply noise sensitive loads at the expense of light load efficiency. When the MODE pin is set low, the buck regulator automatically switches operating modes, depending on the load current level. At higher output loads, the buck regulator operates in PWM mode. When the load current falls below a predefined threshold, the regulator operates in power save mode (PSM), improving light load efficiency.The ADP2138/ADP2139 operate on input voltages of 2.3 V to 5.5 V, which allows for single lithium or lithium polymer cell, multiple alkaline or NiMH cell, PCMCIA, USB, and other standard power sources. The maximum load current of 800 mA is achievable across the input voltage range.The ADP2138/ADP2139 are available in fixed output voltages of 3.3 V, 3.0 V, 2.8 V, 2.5 V, 1.8 V, 1.5 V, 1.2 V, 1.0 V, and 0.8 V. All versions include an internal power switch and synchronous rectifier for minimal external part count and high efficiency. The ADP2138/ADP2139 have internal soft start and they are internally compensated. During logic controlled shutdown, the input is disconnected from the output and the ADP2138/ADP2139 draw 0.2 ?A (typical) from the input source.Other key features include undervoltage lockout to prevent deep battery discharge, and soft start to prevent input current overshoot at startup. The ADP2138/ADP2139 are available in a 6-ball wafer level chip scale package (WLCSP).Applications PDAs and palmtop computers Wireless handsets Digital audio, portable media players Digital cameras, GPS navigation units
