LINEAR INTEGRATED CIRCUIT
HIGH PERFORMANCE 80 dB COMPANDOR
The LS150 is a monolithic integrated circuit in 14-lead dual in-line ceramic and plastic packages; it per-
forms signal level expansion in an 80-dB range [with an overall accuracy of ± 0.2 dB in a 60 dB range1
and, when used in the feedback path of an operational amplifier, it performs complementary signal compression. The LS150 has been designed to improve audio channel signal-to-noise ratio according to CCITT recommendations which require an unaffected reference level of-14 dBm across 600n. The device can also be used to reduce crosstalk and may be converted into a unity gain ampl ifier for data transmission links by means of a simple switch without affecting output and input impedance levels.
