The LMZ13610/8 and LMZ12010/8 SIMPLE SWITCHER® power modules are easy-to-use DC-DC solution capable of driving up to a 10A load. They are available in an innovative package that enhances thermal performance and allows for hand or machine soldering. The LMZ13610/8 can accept an input voltage rail between 6V and 36V and the LMZ12010/8 can accept an input voltage rail between 6V and 20V. The devices can deliver an adjustable and highly accurate output voltage as low as 0.8V and as high as 6V. The control structure is constant frequency PWM. The control loop operates well with low ESR output capacitors such as ceramics. The precision enable input allows for programmable UVLO of the input supply. The external soft-start capacitor facilitates a controlled and adjustable startup rise time of the output. The LMZ13610 and LMZ12010 family is a reliable and robust solution with the following features: loss-less cycle-by-cycle valley current limit to protect for over current or short-circuit fault, thermal shutdown, input under-voltage lockout, and will start up into a pre-biased output. Free-running switching frequency is 350 kHz.

The AD7405 is a high performance, second-order, ?-? modulatorthat converts an analog input signal into a high speed, single-bitLVDS data stream, with on-chip digital isolation based onAnalog Devices, Inc., iCoupler? technology. The AD7405operates from a 5 V (VDD1) power supply and accepts adifferential input signal of ?250 mV (?320 mV full-scale). Thedifferential input is ideally suited to shunt voltage monitoring inhigh voltage applications where galvanic isolation is required.The analog input is continuously sampled by a high performanceanalog modulator, and converted to a ones density digital outputstream with a data rate of up to 20 MHz. The originalinformation can be reconstructed with an appropriate digitalfilter to achieve 88 dB signal to noise ratio (SNR) at 78.1 kSPS.The LVDS input/output can use a 5 V or a 3.3 V supply (VDD2).The LVDS interface is digitally isolated. The LVDS interfacetechnology, combined with monolithic transformer technology,means the on-chip isolation provides outstanding performancecharacteristics, superior to alternatives such as optocouplerdevices. The AD7405 device is offered in a 16-lead, wide-bodySOIC package and has an operating temperature range of ?40?Cto +125?C.Applications Shunt current monitoring AC motor controls Power and solar inverters Wind turbine inverters Data acquisition systems Analog-to-digital and opto-isolator replacements

When a dc/dc converter providing a regulated output voltage between the minimum and maximum input voltage is required neither a single buck or a boost converter can provide the output voltage. However a boost converter integrated circuit (IC) can be configured to drive a single-ended primary-inductor converter (SEPIC) power stage and provide an output voltage that is between the input voltage e

The ADL8107 is a gallium arsenide (GaAs), monolithic microwave IC (MMIC), pseudomorphic high electron mobility transistor (pHEMT), low noise, wideband, high linearity amplifier that operates from 6 GHz to 18 GHz.The ADL8107 provides a typical gain of 24 dB at 7 GHz to 16 GHz, a 1.3 dB typical noise figure at 7 GHz to 16 GHz, a 18.5 dBm typical output power for 1 dB compression (OP1dB) at 7 GHz to 16 GHz, and a typical output third-order intercept (OIP3) of 29 dBm at 7 GHz to 16 GHz, requiring only 90 mA from a 5 V drain supply voltage. This low noise amplifier has a high output second-order intercept (OIP2) of 30.5 dBm typical at 7 GHz to 16 GHz, making the ADL8107 suitable for military and test instrumentation applications.The ADL8107 also features inputs and outputs that are internally matched to 50 ?. The RFIN and RFOUT pins are internally ac-coupled, and the bias inductor is also integrated, making the ADL8107 ideal for surface-mounted technology (SMT)-based, high density applications.The ADL8107 is housed in a RoHS-compliant, 2 mm ? 2 mm, 8-lead LFCSP.APPLICATIONSTest instrumentationMilitary communicationsRadar

The ADL5920 is an ultrawideband, bidirectional detector that simultaneously measures forward and reverse rms power levels in a signal path, along with the return loss.The forward and reverse power traveling through the integrated bidirectional bridge is measured using two 50 dB linear in dB rms detectors. The detector output voltages, available at the VRMSF and VRMSR pins, are proportional to the forward and reflected power in dBm. A third, differential, output produces a voltage proportional to the return loss (reflection coefficient) in dB, closely related to the voltage standing wave ratio (VSWR). The common-mode level of this output is externally adjustable through the VOCM pin.The primary transmission line of the bidirectional bridge, from RFIN to RFOUT (or vice versa) is dc-coupled and allows small amounts of dc bias current through the bridge. When dc-coupled to source and load, the positive and negative supply pins of the ADL5920 must be connected to +5 V and ?2.5 V, respectively (relative to the dc voltage at RFIN and RFOUT). The internal detector circuitry is also dc-coupled to the directional bridge to support measurements down to 9 kHz.The maximum input signal on each of the RF ports (RFIN and RFOOUT) is 30 dBm for open and shorted terminations and 33 dBm for a matched termination.The ADL5920 draws 160 mA from a 5 V supply and has a low power, power-down mode controlled through the PWDN/TADJS pin.The device is supplied in a 32-lead, 5 mm ? 5 mm LFCSP and is specified for ambient operating temperatures in the ?40?C to +85?C range.Multifunction pin names may be referenced by their relevant function only.Applications Industrial metering Broadband inline power and return loss measurement Transmit power control and automatic level control in wireless transmitters, signal generators, network analyzers, and wireless communications testers Condition based monitoring of system modules, cables, and connectors
