Linear Technology Corporation introduces the LTC4282, an energy monitoring Hot Swap controller with dual MOSFET drive to enable 100A and higher current board designs. The LTC4282 ensures safe board insertion and removal from live 2.9V to 33V backplanes by controlling external N-channel MOSFETs to gently power up capacitors, avoiding sparks, connector damage and system glitches. High current hot-pluggable boards utilize parallel MOSFETs to reduce voltage drop, but all of these MOSFETs require large safe operating area (SOA) to ride through overcurrent faults. By controlling two matching current limited paths, the LTC4282 halves each path’s SOA requirements, reducing MOSFET … Read More → "Energy Monitoring Hot Swap Controller Enables 100A Board Designs"

MILPITAS, CA – September 29, 2015 – Linear Technology Corporation introduces the LTC2387-18, an ultrafast 15Msps, 18-bit successive approximation register (SAR) analog-to-digital converter (ADC) with no cycle latency and no pipeline delay. The LTC2387-18 digitizes wideband analog signals up to the Nyquist frequency with very low distortion. Applications ranging from communications, high speed imaging and instrumentation that traditionally utilize fast throughput pipelined ADCs can now achieve 20dB signal-to-noise ratio (SNR) improvement compared to pipelined ADC architectures.

The LTC2387-18 achieves an SNR of 95.7dB and realizes -101dB total harmonic distortion (THD) while digitizing a 1MHz analog input signal. … Read More → "15Msps, 18-Bit No Latency SAR ADC Provides 20dB SNR Improvement over Pipelined ADCs"
