Chameleon™ 8th-Order Butterworth Lowpass Filter Modules
Okika Devices high-performance, 8th-order Butterworth devices deliver precision lowpass filtering
Okika Devices Chameleon modules (OTC931xL) are high-performance, 8th-order Butterworth lowpass filters built on the AN231E04 field-programmable analog array (FPAA). Each module features an internal clock and EEPROM to deliver fixed function, characterized filter performance across a wide range of cutoff frequencies (10 Hz to 100 kHz).
Features
- 8th-order Butterworth filter: flat passband, low ringing
- FPAA-based with internal EEPROM: programmable or fixed-function
- Differential signal path: max dynamic range, reduced noise
- Input amplifier for easy single-supply interfacing
- Optional AC coupling and bypassable amplifier
- Buffered/unbuffered outputs for ADCs or cascaded modules
- Complementary sample clock outputs for ADC sync
- Dual-channel support
Applications
- Industrial automation
- Biomedical instrumentation
- Audio and acoustic processing
- Sensor signal conditioning
- ADC antialiasing and post-DAC smoothing
- Custom analog front ends and prototyping
