• Description: Analog-storage Single-chip Record/playback With Bit-cell Flash Memory
• Manufacturer: Oki Optical Components

LPF Characteristics
The LSI has an on-chip 4-stage LPF which utilizes Switched Capacitor Filtering technology. Attenuation is set to
–40dB/oct. while the cut-off frequency and frequency characteristics vary in proportion to the sampling frequency
(fs) selected. The cut-off frequency is set to 0.4 level of the selected sampling frequency.
Power Supply Circuit Design
As shown in the following figure, power supply to the LSI must be designed to have a single power source, and
separate wiring for analog section and logic section.
The following figures are bad wiring samples you should avoid.
