759N

www.DataSheet4U.com Economy, Wideband Log/Antilog Amplifiers Models 759N, 759P FEATURES Low-Cost, Complete Log/Antilog Amplifier External Components Not Required; Internal Reference; Temperature Compensated Small Size: 1.1" x 1.1" x 0.4" Fast Response: 200kHz Bandwidth (ISIG @ 1µA) 6 Decades Current Operation - 1nA to 1mA 1% max Error - 20nA to 200µA 2% max Error - 10nA to 1mA 4 Decades Voltages Operation - 1 mV to 10V 1% max Error - 1mV to 2V 2% max Error - 1mV to 10V APPLICATIONS Log Current or Voltage Antilog Voltage Data Compression or Expansion measurements, data compression and expansion, chemical analysis of liquids, computing powers, roots and ratios and conversion of exponential quantities to linear form. GENERAL DESCRIPTION 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 200µA, as well as 2% conformance over four decades of voltage operation - 1mV to 10V. Featuring 200kHz bandwidth at ISIG = 1µA, 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,...
