Calogic, LLC : Cross It, Crack It, Switch-Update It

Based in Fremont, California, Calogic, LLC is a specialized design and manufacturing house of analog semiconductors. Established in 1983, Calogic is ROHS (Restriction of Hazardous Substances) compliant and ISO 9001:2008 certified to produce Bipolar Junction Isolated (JI) and Dielectrically Isolated (DI) products for the power management, telecommunications, computer, instrumentation, and medical markets. Situated in the Silicon Valley, Calogic utilizes silicon gate technology to build the following discrete devices and switch arrays:

  • DMOS Switches: Engineered with Calogic’s patented high speed, low capacitance DMOS (double-diffusion metal-oxide semiconductor) process, the SD5000 Series features monolithic arrays of four bidirectional analog switches that operate with a maximum threshold of 2V. Calogic DMOS switches are perfect for simple TTL (transistor-transistor logic) and CMOS (complementary metal-oxide semiconductor) driving in small signal applications, such as audio routing, analog switching, and crosspoint switching.
  • JFET Switches: Designed to be cost-efficient, Calogic JFET (junction gate field-effect transistor) switches have low insertion loss, emit little noise, and come with an automated insertion package.
  • JFET Amplifiers: Designed using Calogic’s trademarked JFET (junction field-effect transistor) processing techniques, the SST404 Series of low noise, low leakage, monolithic semiconductors are surface mountable. With a very low noise output, Calogic’s JFET amplifiers are ideal for sensitive applications, such as precision instrumentation and medical purposes.
  • MOSFETs: Manufactured with a diode-protected gate and a high input impedance, Calogic’s MOSFETs (metal-oxide semiconductor field-effect transistor) are used to switch electronic signals.
  • Buffers: Ideal for line driving, radar, and sonar applications, the CLM6121 Series of high speed unity gain buffers takes up minimal bandwidth (100MHz) and continuously outputs a current of +/-200mA.
