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.
FEATURES
I Supply voltage range: 3.0 to 3.6V
I Operating ambient temperature range: −20 to +80°C
I 2-system input and output (reverse phase output)
I Corresponds to 2-axis of gyroscope output
I Adjustable output gain and frequency characteris-
tics by external components
I Output gain: 30 to 50dB
(variable amplification control)
I Zero-rate voltage compensation function for sim-
ple interface to A/D converter connected to subse-
quent stage
I Sleep function built-in
I Small package: 16-pin QFN
