SM6661A

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 2system 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 subsequent stage I Sleep function built-in I Small package: 16-pin QFN PINOUT (Top view) VCC SLEEP VSIG_OUT1 GAIN1 VSIG_OUT2 GAIN2 HPF2 GND VSIG_IN2 VREF_IN2 VCC/2 GND HPF1 VCC VREF_IN1 VSIG_IN1 APPLICATIONS I DVC I DSC ORDERING INFORMATION Device SM6661AB Package 16-pin QFN PACKAGE DIMENSIONS (Unit: mm) Weight: 9mg Top view 2.50 ± 0.05 Bottom view 1.30 ± 0.05 2.50 ± 0.05 0.60 max 1.30 ± 0.05 0.40 16 1 0.40 ± 0.05 0.325 ± 0.05 0.05 0.40 16 1 C0.05 0.18 ± 0.05 0.08 ± 0.05 0.05 M SEIKO NPC CORPORATION —1 BLOCK DIAGRAM SM6661A VREF_IN1 VSIG_IN1 GND VCC/2...
