DC480A-F: Demo Board for the LTC3405A 1.5MHz, 300mA Synchronous Step-Down Regulator in ThinSOT.

Demonstration circuit 2044B is a 55V buck-boost multi-chemistry battery charger featuring the LTC4020. The board will accept an input voltage between 15V and 55V. The float voltage of the battery output (BAT) is 25.2V, with 3.3A maximum charge current. The converter output (VOUT) has a voltage range of 21V to 28V, with 3A maximum load current. The LTC4020 contains a high efficiency synchronous buck-boost DC/DC controller and uses a proprietary average current mode architecture. The LTC4020 battery charger can provide a constant-current/constant-voltage charge algorithm (CC/CV); a four-step, three-stage lead-acid battery-charge profile or constant-current charging (CC). Battery-chemistry type is selected using on-board jumper JP1. The LTC4020 data sheet gives a complete description of the IC operation and application information. The data sheet must be read in conjunction with the quick start guide.

Demonstration circuit DC915 features the LT3466-1 high efficiency boost white LED driver and a step-up converter. There is one LED driver output for 6 or 8 WLEDs and a separate DC/DC converter that generates outputs for the LCD bias. VO1 drives 8 LEDs in series with 15mA LED current and VO2/VO3 can delivery ±15V at 10mA current. If the charge-pump circuitry which generates VO3 is removed (C4, C5 and D1), VO2 can deliver over 35mA of current. The input voltage range is 3V to 14V, but can go as low as 2.7V with slightly reduced output current.

DC1593A-A: Demo Board for the LTC2635-12 Quad 12-Bit I2C VOUT DACs with 10ppm/°C Reference.

The EVAL-ADXL371Z is a simple evaluation board that allows quick evaluation of the performance of the ADXL371 ultralow power, 3-axis, digital output MEMS accelerometer. The EVAL-ADXL371Z is ideal for evaluation of the ADXL371 in an existing system because the stiffness and the small size of the evaluation board minimize the effect of the board on both the system and acceleration measurements. For full specifications on the ADXL371, see the ADXL371 data sheet, which should be consulted in conjunction with the user guide when using this evaluation board.

The LT1511 current mode PWM battery charger is the simplest, most efficient solution to fast charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The internal switch is capable of delivering 3A* DC current (4A peak current). Full-charging current can be programmed by resistors or a DAC to within 5%. With 0.5% reference voltage accuracy, the LT1511 meets the critical constant-voltage charging requirement for Li-Ion cells. A third control loop is provided to regulate the current drawn from the AC adapter. This allows simultaneous operation of the equipment and battery charging without overloading the adapter. Charging current is reduced to keep the adapter current within specified levels. The LT1511 can charge batteries ranging from 1V to 20V. Ground sensing of current is not required and the battery?s negative terminal can be tied directly to ground. A saturating switch running at 200kHz gives high charging efficiency and small inductor size. A blocking diode is not required between the chip and the battery because the chip goes into sleep mode and drains only 3?A when the wall adapter is unplugged.* See LT1510 for 1.5A ChargerApplications Chargers for NiCd, NiMH, Lead-Acid, Lithium Rechargeable Batteries Switching Regulators with Precision Current Limit

The ADIS16260?and ADIS16265 are programmable digital gyroscopes that combine industry-leading MEMS and signal processing technology in a single compact package. They provide accuracy performance that would require full motion calibration with any other MEMS gyroscope in their class. When power is applied, the ADIS16260 and ADIS16265 automatically start up and begin sampling sensor data, without requiring configuration commands from a system processor. An addressable register structure and a common serial peripheral interface (SPI) provide simple access to sensor data and configuration settings. Many digital processor platforms support the SPI with simple firmware-level instructions.The ADIS16260 and ADIS16265 provide several programmable features for in-system optimization. The sensor bandwidth switch (50 Hz and 330 Hz), Bartlett window FIR filter length, and sample rate settings provide users with controls that enable noise vs. bandwidth optimization. The digital input/output lines offer options for a data ready signal that helps the master processor efficiently manage data coherency, an alarm indicator signal for triggering master processor interrupts, and a general-purpose function for setting and monitoring system-level digital controls/ conditions.The ADIS16260 and ADIS16265 are drop-in replacements for the ADIS1625x family and come in LGA packages (11.2 mm ? 11.2 mm ? 5.5 mm) that meet Pb-free solder reflow profile requirements, per JEDEC J-STD-020.
