Product Details
The MAX293 is a 8th order, lowpass, elliptic,
switched capacitor filter. The IC can be set-up with corner
frequencies from 0.1Hz to 25kHz.
The MAX293 can operate from the internal clock signal or an external
clock signal can be used. The MAX293 also includes an uncommitted
op-amp which can used for post-filtering or anti-aliasing.
Features
- 8th-Order Lowpass Elliptic Filters: Bessel
- Clock-Tunable Corner-Frequency Range: 0.1Hz to 25kHz
- No External Resistors or Capacitors Required
- Internal or External Clock
- Clock to Corner Frequency Ratio: 100:1
- Operate with a Single +5V Supply or Dual ±5V Supplies
- Uncommitted Op Amp for Anti-Aliasing or Clock-Noise Filtering
