The LTC4359 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. A shutdown mode is available to reduce the quiescent current to 9?A for load switch and 14?A for ideal diode applications.When used in high current diode applications, the LTC4359 reduces power consumption, heat dissipation, voltage loss and PC board area. With its wide operating voltage range, the ability to withstand reverse input voltage, and high temperature rating, the LTC4359 satisfies the demanding requirements of both automotive and telecom applications. The LTC4359 also easily ORs power sources in systems with redundant supplies.Applications Automotive Battery Protection Redundant Power Supplies Supply Holdup Telecom Infrastructure Computer Systems/Servers Solar Systems

The HMC678LC3C is a 2:1 Selector designed to support data transmission rates of up to 13 Gbps, and selector port operation of up to 13 GHz. The selector routes one of the two single-ended inputs to the differential output upon assertion of the proper select port. All single-ended input signals to the HMC678LC3C are terminated with 50 ohms to ground on-chip, and may be either AC or DC coupled.The outputs of the HMC678LC3C may be operated either differentially or single-ended. Outputs can be connected directly to a 50 ohm terminated system, while DC blocking capacitors may be used if the terminating system is 50 ohms to a non-ground DC voltage.

Demonstration Circuit 425B is a constant-frequency synchronous Buck-Boost converter using the LTC3440. The input range is from 2.5V to 5.5V, making it ideal for single-cell lithium-ion or three-cell NiCd/NiMH battery applications. For 2.7V minimum input voltage, this converter can provide up to 600mA load current. The output voltage is set at 3.3V. A different output voltage in the range of 2.5V to 5.5V can be obtained by changing one of the feedback resistors.

The AD8276/AD8277?are general-purpose, unity-gain difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and low power. They provide exceptional 86 dB common-mode rejection ratio (CMRR) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser trimmed for gain drift of 1 ppm/?C and high CMRR. The AD8276/AD8277 also have extremely low gain drift vs. temperature.The common-mode range of the amplifiers extends to almost double the supply voltage, making these amplifiers ideal for single-supply applications that require a high common-mode voltage range. The internal resistors and electrostatic discharge (ESD) circuitry at the inputs also provide overvoltage protection to the op amps.The AD8276/AD8277 are unity-gain stable. Although they are optimized for use as difference amplifiers, they can also be connected in high precision, single-ended configurations with G = ?1, +1, or +2. The AD8276/AD8277 provide an integrated precision solution that has smaller size, lower cost, and improved performance than a discrete alternative.The AD8276/AD8277 operate on single supplies (2.0 V to 36 V) or dual supplies (?2 V to ?18 V). The maximum quiescent supply current is 200 ?A per channel, which is ideal for battery-operated and portable systems.The AD8276 is available in the space-saving 8-lead mini small outline package (MSOP) and the standard small outline (SOIC) package, as well as in die form, and the AD8277 is offered in a 14-lead SOIC package. Both are specified for performance over the industrial temperature range of ?40?C to +85?C and are fully RoHS compliant.Applications Voltage measurement and monitoring Current measurement and monitoring Differential output instrumentation amplifier Portable, battery-powered equipment Test and measurement

The AD8129/AD8130 are designed as receivers for the transmission of high speed signals over twisted-pair cables to work with the AD8131 or AD8132 drivers. Either can be used for analog ordigital video signals and for high speed data transmission.The AD8129/AD8130 are differential-to-single-ended amplifiers with extremely high CMRR at high frequency. Therefore, they canalso be effectively used as high speed instrumentation amps or for converting differential signals to single-ended signals.

Demonstration circuit 862 is a micropower regulated charge pump DC/DC converter featuring the 60mA output LTC3221 in a 2mm × 2mm DFN package. It comes in three assembly versions, DC862A-A, DC862A-B and DC862A-C, featuring the LTC3221EDC-3.3 (fixed 3.3V output), the LTC3221EDC-5 (fixed 5V output) , and LTC3221EDC (adjustable output set to 3V), respectively. The demo board input voltage range depends on the IC used; for the adjustable output DC862A-C, the input voltage range is 1.8V to 3.8V. The LTC3221's low 8µA no-load quiescent current is even lower than the self-discharging current of many batteries. By employing a constant current to charge the output, the output ripple is low even at high input and light load, and is fairly constant over the full input voltage range.
