The VCA610UA is a wideband, continuously variable, voltage-controlled gain amplifier designed by B&B Smartworx. It provides linear-dB gain control with high impedance inputs, making it suitable for flexible gain-control elements in various electronic systems.
This amplifier features a wide gain control range of 77dB (–38.5dB to +38.5dB), allowing for both gain and attenuation. It has a signal bandwidth of 30MHz and a low voltage noise of 2.2nV/√Hz. The gain slew rate is fast at 300dB/µs, with a settling time of 800ns.
The VCA610UA is housed in a small SO-8 package. Its broad attenuation range can be used for gradual channel turn-on and turn-off. The output can be disabled to provide –77dB of attenuation. Group delay variation with gain is typically less than ±2ns across a bandwidth of 1MHz to 15MHz.
Applications for the VCA610UA include optical distance measurement, AGC amplifiers, ultrasound, sonar, active filters, log amplifiers, IF circuits, and CCD cameras. It is designed with a fast overload recovery time of 200ns.
