quad version of the LM4250 chip used in many Polivoks VCF clones . Until now no-one had adapted it to synth use, despite a datasheet promoting its use in filters. As the Polivoks was an adaptation of the classic OTA-based 2-pole State Variable Filter we thought we would go in the opposite direction and try the 4-pole cascad- LM4250 Datasheet (PDF) - National Semiconductor (TI) [Old version datasheet] Texas Instruments acquired National semiconductor.

This is a much improved quad version of the LM4250 chip that is used in many Polivoks VCF clones (and the UA776 chip which was itself copied by the Soviets!) which has been hiding in plain sight for almost 40 years now. Until now no-one has adapted it to synth use, despite a datasheet promoting its use in filters.
Jun 28, 2019 · Simple 2 band-EQ with low current draw and should be small enough to tuck into the control cavity of whatever bass you're wanting to add it to. Other single opamps can be used, but the current draw may increase, draining your 9v battery quicker. For example a TL071 draws 10x the current of the LM4250. A good replacement would be the LT1351.

All circuits of this series are capable of driving a 1.0 A load with excellent line and load regulation.
(4) The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V (at 25°C). The upper end of the common-mode voltage range is V+ −1.5 V (at 25°C), but either or both inputs can go to 32 V without damage (26 V for LM2904), independent of the magnitude of V+.

The LM4250 is a fairly unique device and we're not sure there is a direct replacement for it. However, many modern amplifiers can achieve similar (or better) performance metrics than the LM4250 when configured in basic topologies. Nov 28, 2006 · I am hoping to replace the somewhat dated LM741 opamps in an old 1970s PKE phono preamp. There are 3 in each channel (6 total).
