DC708A: Demo Board for the LTC4064 Monolithic Linear Charger for Back-Up Li-Ion Batteries.

The LT3468/LT3468-1/LT3468-2 are highly integrated ICs designed to charge photoflash capacitors in digital and film cameras. A patented control technique* allows for the use of extremely small transformers. Each device contains an on-chip high voltage NPN power switch. Output voltage detection* is completely contained within the device, eliminating the need for any discrete zener diodes or resistors. The output voltage can be adjusted by simply changing the turns ratio of the transformer. The LT3468 has a primary current limit of 1.4A, the LT3468-2 has a 1A limit, and the LT3468-1 has a 0.7A limit. These different current limit levels result in well controlled input currents of 500mA for the LT3468, 375mA for the LT3468-2 and 225mA for the LT3468-1. Aside from the differing current limit, the three devices are otherwise equivalent.The CHARGE pin gives full control of the part to the user. Driving CHARGE low puts the part in shutdown. The DONE pin indicates when the part has completed charging. The LT3468 series of parts are available in tiny low profile (1mm) SOT-23 packages.Applications Digital / Film Camera Flash PDA / Cell Phone Flash Emergency Strobe

The LTC5530 is an RF power detector for RF applications operating in the 300MHz to 7GHz range. A temperature compensated Schottky diode peak detector and buffer amplifier are combined in a small ThinSOT? package. The supply voltage range is optimized for operation from a single lithium-ion cell or 3xNiMH.The RF input voltage is peak detected using an on-chip Schottky diode. The detected voltage is buffered and supplied to the VOUT pin. The output buffer gain is set via external resistors. A power saving shutdown mode reduces current to less than 2?A.The LTC5530 operates with input power levels from -32dBm to 10dBm.*Higher frequency operation is achievable with reduced performance.

Demonstration Circuit 725 is a 7A high efficiency, phase-lockable constant frequency buck converter, incorporating the LTC3415 polyphase monolithic synchronous regulator. The DC725 has an input voltage range of 2.375V to 5.5V and an output voltage range from 0.6V to 5V. The output voltage can be set to 1.2V, 1.5V or 1.8V using the appropriate jumper connection, or it can be set to an adjustable value down to 0.6V, the reference voltage of the LTC3415. The DC725 can deliver high power for a monolithic part (up to 7A of output current) due to the high current power switches (28 mΩ of onstate resistance) of the LTC3415. The LTC3415 can also do polyphase operation, which allows multiple DC725s to be used in parallel for higher current power supplies. Since the parallel LTC3415s can operate out-of-phase, the amount of input and output capacitance required will be minimal.

The AD5362 / AD5363 contains 8, 16/14-bit DACs in a single, 56-lead, LFCSP or 52-lead LQFP package. It provides buffered voltage outputs with a span 4 times the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into two groups of 4 DACs, and the output range of each group can be independently adjusted by an offset DAC.The AD5362 / AD5363 offers guaranteed operation over a wide supply range with VSS from -4.5 V to -16.5 V and VDD from +8 V to +16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.The AD5362 / AD5363 has a high-speed serial interface, which is compatible with SPI?, QSPI?, MICROWIRE?, and DSP interface standards and can handle clock speeds of up to 50 MHz. All the outputs can be updated simultaneously by taking the LDAC input low. Each channel has a programmable gain and an offset adjust register.Each DAC output is amplified and buffered on-chip with respect to an external SIGGND input. The DAC outputs can also be switched to SIGGND via the CLR pin.APPLICATIONS Instrumentation Industrial Control System Level setting in automatic test equipment (ATE) Variable optical attenuators (VOA) Optical line cards

The AD5410/AD5420 are low cost, precision, fully integrated 12-/16-bit converters offering a programmable current source output designed to meet the requirements of industrial process control applications. The output current range is programmable at 4 mA to 20 mA, 0 mA to 20 mA, or an overrange function of 0 mA to 24 mA. The output is open-circuit protected. The device operates with a power supply (AVDD) range from 10.8 V to 60 V. Output loop compliance is 0 V to AVDD ? 2.5 V.The flexible serial interface is SPI, MICROWIRE?, QSPI?, and DSP compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications.The device also includes a power-on reset function, ensuring that the device powers up in a known state, and an asynchronous CLEAR pin that sets the output to the low end of the selected current range.The total unadjusted error is typically ?0.01% FSR.Applications Process control Actuator control PLC HART network connectivity
