LMF100 - Dual High-Performance Switched Capacitor Filters

General Description

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

With an external clock and two to four resistors, each filter block can realize various second-order and first-order filtering functions.

Each block has three outputs.

Key Features

  • 1 Wide 4-V to 15-V Power Supply Range.
  • Operation up to 100 kHz.
  • Low Offset Voltage:.
  • Typically (50:1 or 100:1 mode):.
  • Vos1 = ±5 mV.
  • Vos2 = ±15 mV.
  • Vos3 = ±15 mV.
  • Low Crosstalk:.
  • 60 dB.
  • Clock to Center Frequency Ratio Accuracy ±0.2% (Typical).
  • f0 × Q Range up to 1.8 MHz.
  • Pin-Compatible With MF10 2.
