DC1281A-A: Demo Board for LTC2209 16-Bit, 160Msps ADC

The LTM4606 is a complete EN55022 Class B certified noise high voltage 6A switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor, and all support components. The on-board input filter and noise cancellation circuits achieve low noise operation, thus effectively reducing the electromagnetic interference (EMI). Operating over an input voltage range of 4.5V to 28V, the LTM4606 supports an output voltage range of 0.6V to 5V, set by a single resistor. This high efficiency design delivers 6A continuous current (8A peak). Only bulk input and output capacitors are needed to finish the design.High switching frequency and an adaptive on-time current mode architecture enables a very fast transient response to line and load changes without sacrificing stability. The device supports output voltage tracking and output voltage margining.Furthermore, the ?Module? regulator can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase? operation for high load currents.The LTM4606 is offered in space saving 15mm ? 15mm ? 2.82mm LGA and 15mm ? 15mm ? 3.42mm BGA packages. The LTM4606 is available with SnPb (BGA) or RoHS compliant terminal finish.APPLICATIONS ASICs or FPGA Transceivers Telecom, Servers and Networking Equipment Industrial Equipment RF Equipment

The LTC2631 is a family of 12-, 10-, and 8-bit voltage-output DACs with an integrated, high accuracy, low-drift reference in an 8-lead TSOT-23 package. It has a rail-to-rail output buffer that is guaranteed monotonic.The LTC2631-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2631-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. A 10ppm/?C reference output is available at the REF pin.Each DAC can also operate in External Reference mode, in which a voltage supplied to the REF pin sets the fullscale output.The LTC2631 DACs use a 2-wire, I2C-compatible serial interface. The LTC2631 operates in both the standard mode (clock rate of 100kHz) and the fast mode (clock rate of 400kHz).The LTC2631 incorporates a power-on reset circuit. Options are available for reset to zero-scale or reset to mid-scale after power-up.Applications Mobile Communications Process Control and Industrial Automation Automatic Test Equipment Portable Equipment Automotive Optical Networking

Demonstration circuit 1340 is a triple output regulator consisting of three constant-frequency step-down converters integrated into LTC3569. DC1340 has an input voltage range of 2.5V to 5.5V, with regulators capable of delivering 1.2A or 600mA of load current on corresponding output. The three regulators operate independently with individual Enable pins and enter pulse skipping or burst mode at low loads for increasing efficiency. The DC1340 is a very efficient circuit with efficiency reading above 90%. High operating frequency of 2.25MHz allows exclusive use of the small size, low profile surface mount components. These features plus internal compensation circuits and extremely low quiescent current make the DC1340 demo board an ideal circuit for use in battery-powered, hand-held applications.

The LTC5542 is part of a family of high dynamic range, high gain, passive downconverting mixers covering the 600MHz to 4GHz frequency range. The LTC5542 is optimized for 1.6GHz to 2.7GHz RF applications. The LO frequency must fall within the 1.7GHz to 2.5GHz range for optimum performance. A typical application is a LTE or WiMAX receiver with a 2.3GHz to 2.7GHz RF input and low-side LO. The LTC5542 is designed for 3.3V operation, however; the IF amplifier can be powered by 5V for the highest P1dB. An integrated SPDT LO switch with fast switching accepts two active LO signals, while providing high isolation. The LTC5542?s high conversion gain and high dynamic range enable the use of lossy IF filters in high-selectivity receiver designs, while minimizing the total solution cost, board space and system-level variation.Applications Wireless Infrastructure Receivers (LTE, W-CDMA.

Demonstration circuit 1472 features the LTM4618EV μModule® regulator, a complete high efficiency synchronous buck regulator with tracking. The DC1472 input range is from 4.5V to 26.5V and is capable of delivering up to 6A of output current; however, current derating may be necessary under certain VIN, VOUT, frequency and thermal conditions. The output voltage is jumper programmable from 1.2V to 5V and can be set as low as 0.8V, the reference voltage of the LTM4618EV.

Demonstration circuit 1489A is a synchronous buck dual regulator with adjustable input current limit featuring the LTC3619EDD(Burst mode operation)/LTC3619BEDD(pulse-skip mode) and is ideally suited for pulsed load applications where the input current needs to be limited. The -A board is for the LTC3619 while the -B board is for the LTC3619B. It is configured for 500mA maximum input current limit. The outputs are configured for a 3.3V/400mA continuous current output and a 3.4V output that can handle pulsed load currents up to 2A, with duty cycles up to 15%. The input voltage range is 5V ±10%. The fixed input current limited can be adjusted by replacing one resistor.
