SM6661A
Post-amplifier for Gyroscope
OVERVIEW
The SM6661A is a post-amplifier for use in combination with gyroscope ICs. The SM6661A has a built-in 2-
system post-amplifier, so that it can amplify two output signals of gyroscope IC with a single SM6661A. It
features a simple method to change the different image stabilizing gain and frequency characteristics
depending on the models. It also has a built-in sleep function making it easy to connect the output signal of
gyroscope IC to A/D converter.
