Models 759N and 759P are low cost, fast response, dc logarithmic amplifiers offering 1% conformance to ideal log operation over four decades of current operation - 20nA to 200mA, as well as 2% conformance over four decades of voltage operation - 1mV to 10V. Featuring 200kHz bandwidth at ISIG = 1mA, these new economy designs are the industry's fastest log/antilog amplifiers and offer an attractive alternative to in-house designs.
Designed for ease of use, models 759N/P are complete, temperature compensated, log or antilog amplifiers packaged in a small 1.1" x 1.1" x 0.4" epoxy encapsulated module. External components are not required for logging currents over the complete six decade operating range from 1nA to 1mA. Both the scale factor (K = 2, 1, 2/3 volt/decade) and log/antilog operation can be selected by simple pin interconnection. In addition both the internal 10mA reference current as well as the offset voltage may be externally adjusted to improve overall accuracy performance.
