Voltage controlled operational amplifier
BA6110FS
The BA6110FS is a low-noise, low-offset programmable operational amplifier. Offering superb linearity over a broad
range, this IC is designed so that the forward direction conductivity (g
m
) can be changed, making it ideal for applications
such as voltage control amplifiers (VCA), voltage control filters (VCF) and voltage control oscillators (VCO).
Distortion reduction circuitry improves the signal-to-noise ratio by a significant 10dB at a distortion rate of 0.5% in
comparison with products not equipped with this feature. When used as a voltage control amplifier (VCA), a high S / N
ratio of 86dB can be achieved at a distortion rate of 0.5%.
The open loop gain is determined by the control current and an attached gain determining resistance R
L
, enabling a wide
range of settings.
In addition, a built-in low-impedance output buffer circuit reduces the number of attachments.
