The FLA-01 is a versatile, low cost filter and amplifier combination. It is especially useful as an adjunct to computer A to D or D to A converter, where it can serve the preconditioning/anti-aliasing or reconstruction functions.


The input stage can be configured for single-ended non-inverting, inverting, two-channel summing, or differential amplification. Coupling is selectable, AC, or DC.


  • Eight-pole Bessel filter
  • AC/DC coupling
  • Differential input mode
  • Inverting mode
  • Line frequency notch filter
  • 10 Gain settings (1 to 1000)
  • Input offset compensation
  • 10 frequency ranges (10 Hz to 10 kHz)
