The LTC2377-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2377-16 has a ?VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2377-16 consumes only 6.8mW and achieves ?0.5LSB INL maximum, no missing codes at 16 bits with 97dB SNR.The LTC2377-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 500ksps throughput with no cycle latency makes the LTC2377-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2377-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.The LTC2377-16 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier?s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 ? VREF and full-scale code from VREF to 0.9 ? VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.Applications Medical Imaging High Speed Data Acquisition Portable or Compact Instrumentation Industrial Process Control Low Power Battery-Operated Instrumentation ATE

The LTM2884 is a complete galvanically isolated USB 2.0 compatible ?Module? (micromodule) transceiver.

The ADP1872?/ ADP1873 are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-sense gain, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture. This allows the ADP1872 /ADP1873 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.The ADP1873 is the power-saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads.Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz), the ADP1872 / ADP1873 are well suited for a wide range of applications. These ICs not only operate from a 2.75 V to 5.5 V bias supply, but also can accept a power input as high as 20 V.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a pre-charged output. The low-side current-sense, current-gain scheme, along with the PSM/forced pulse-width modulation (PWM) option, reduces the external part count and improves efficiency. The ADP1872 / ADP1873 operate over the ?40?C to +125?C junction temperature range and are available in a 10-lead MSOP.APPLICATIONS Telecom and networking systems Mid to High End servers Set-top boxes DSP core power supplies
