CLC522 Wideband Variable-Gain Amplifier June 1999 N CLC522 Wideband Variable-Gain Amplifier General Description The CLC522 variable gain amplifier (VGA) is a dc-coupled, twoquadrant multiplier with differential voltage inputs and a single-ended voltage output. Two input buffers and an output operational amplifer are integrated with the multiplier core to make the CLC522 a complete VGA system that does not require external buffering. The CLC522 provides the flexibility of externally setting the maximum gain with only two external resistors. Greater than 40dB gain control is easily achieved through a single high impedance voltage input. The CLC522 provides a linear (in Volts per Volt) relationship between the amplifier's gain and the gain-control input voltage.
