Product Details
The MAX260 is a dual second-order
univeral-switched capacitor active filter which allows
for microprocessor or microcontroller control of the filter functions.
The MAX260 can operate as a bandpass, lowpass, highpass, notch and
allpass configuration. An input clock along with a 6-bit f0
program input control the filter's center or corner frequency.
Features
- Filter Design Software Available
- Microprocessor Interface
- 64-Step Center Frequency Control
- 128-Step Q Control
- Independent Q and fo Programming
- Guaranteed Clock to fo Ratio---1% (A grade)
- Single +5V and ±5V Operation
