The Texas Instruments LOG114 is a precision high-speed logarithmic amplifier designed for a variety of applications requiring accurate logarithmic conversion. This device features a scale factor of 0.375 V/decade and a wide input current range from 0.1 nA to 10 mA.
With a dynamic range of 160 dB and an internal 2.5V reference, the LOG114 provides high performance. It operates over a supply voltage range of ±4.8V to ±11V and supports dual or single supply configurations. The amplifier includes two auxiliary op amps and offers a full-scale output voltage of ±4.4V.
The LOG114 is housed in a compact 16 mm² VQFN package (4 mm × 4 mm), making it suitable for high-density systems. It is specified for operation within a temperature range of 0°C to 70°C, with an alternative specified range of -5°C to 75°C. This component is fully tested and offers precision on a single supply, with fast response over eight decades.
