IMPORTANT: The 2150 Series is OBSOLETE. For easy, pin-compatible replacements, see our 2180 Series or 2181 Series VCAs. We have discontinued all 2150-series Blackmer Voltage Controlled Amplifier ICs. This includes the 2151, 2150A and 2155. We offer the pin-compatible 218x series VCAs as a better, more advanced alternative to the 215x series. Our 218x series offers greater performance at a comparable cost. Substituting THAT 218x series VCAs for 2150 series VCAs in Existing Designs To simplify things, below we have provided a chart of recommended conversions between 215x parts and 2181Lx parts. Of course, you may wish to consider the full range of available 218x ICs at this time, but the chart below shows the default choices.
Additionally, we offer a variation of the 2181 series -- the 2180 Series ICs, which are pre-trimmed for low distortion during wafer processing. In many applications, by switching to one of these ICs you can eliminate a trim pot and two resistors from your current designs, along with the time and labor required to adjust the trim. The 2180Lx ICs are a little more expensive than their 2181Lx counterparts, but the savings in trim components and time more than offsets the additional cost.
