LMF100 Datasheet (National Semiconductor) - High Performance Dual Switched Capacitor Filter

LMF100, High Performance Dual Switched Capacitor Filter

The LMF100 consists of two independent general purpose high performance switched capacitor filters.

With an external clock and 2 to 4 resistors, various second-order and first-order filtering functions can be realized by each filter block.

Each block has 3 outputs.

One output can be configured to pe
