Key Features

  • Precision logarithmic and antilogarithmic amplifier for accurate signal compression and expansion
  • Wide supply voltage range of ±4.5V to ±18V for versatile power configurations
  • Low bandwidth of 10kHz suitable for DC and low-frequency logarithmic signal processing
  • 8-Pin SOIC (R-PDSO-G8) compact package for space-constrained board designs
  • RoHS compliant (Pb-free, JESD-609 e4) meeting modern environmental standards

Applications

The LOG104AID is widely used in instrumentation and measurement systems where signal compression or logarithmic conversion is required, such as audio level detection and wide dynamic range sensor interfaces. It is ideal for scientific instruments, medical diagnostics, and industrial process control applications that demand accurate log/antilog mathematical operations on analog signals. Its wide supply voltage range also makes it suitable for both battery-powered and bench-top laboratory equipment.
