The LTC3621/LTC3621-2 is a high efficiency 17V, 1A synchronous monolithic step-down regulator. The switching frequency is fixed to 1MHz or 2.25MHz with a ?40% synchronizing range. The regulator features ultralow quiescent current and high efficiencies over a wide VOUT range.The step-down regulator operates from an input voltage range of 2.7V to 17V and provides an adjustable output range from 0.6V to VIN while delivering up to 1A of output current. A user-selectable mode input is provided to allow the user to trade off ripple noise for light load efficiency; Burst Mode operation provides the highest efficiency at light loads, while pulse-skipping mode provides the lowest voltage ripple. The MODE pin can also be used to allow the user to sync the switching frequency to an external clock.

The LTM9011-14/LTM9010-14/LTM9009-14 are 8-channel, simultaneous sampling 14-bit A/D converters designed for digitizing high frequency, wide dynamic range signals. AC performance includes 73.1dB SNR and 88dB spurious free dynamic range (SFDR). Low power consumption per channel reduces heat in high channel count applications. Integrated bypass capacitance and flow-through pinout reduces overall board space requirements.DC specs include ?1LSB INL (typ), ?0.3LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1.2LSBRMS.The digital outputs are serial LVDS to minimize the number of data lines. Each channel outputs two bits at a time (2-lane mode). At lower sampling rates there is a one bit per channel option (1-lane mode).The ENC+ and ENC? inputs may be driven differentially or single-ended with a sine wave, PECL, LVDS, TTL, or CMOS inputs. An internal clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles.Applications Communications Cellular Base Stations Software Defined Radios Portable Medical Imaging Multichannel Data Acquisition Nondestructive Testing
