The document describes the TLCO4/MF4A-50 and TLC14/MF4A-100, which are monolithic Butterworth low-pass switched-capacitor filters designed for accurate fourth-order low-pass filter functions. These devices feature cutoff frequency stability dependent only on external clock frequency stability and offer interchangeable options with National Semiconductor MF4-50 and MF4-100 parts.
| Filter Type | Butterworth Fourth-Order Low-Pass Switched-Capacitor Filters |
|---|---|
| Clock-to-Cutoff Frequency Ratio (TLC04) | 50:1 with less than +0.8% error |
| Clock-to-Cutoff Frequency Ratio (TLC14) | 100:1 with less than +1% error |
| Cutoff Frequency Range | 0.1 Hz to 30 kHz |
| Operating Temperature Range (Military) | -55°C to 125°C |
Yes, they are designed to be interchangeable with National MF4-50 and MF4-100.
The ratio is 100:1 with less than +1% error.
