The Elec Druid TAPLFO 2D chip generates a number of PWM LFO waveforms that can be used in stompboxes and synth applications. DIP14.

The Electric Druid PENTANOISE is a five channel digital noise source that produces independent pure white noise over the whole audio band. With only two resistors and two capacitors on each output, you can build five independent channels of analog white noise. DIP8.

The NOISE2 is a significant update to the Electric Druid original NOISE chip. Now it includes a pink noise source too, without the need for external pinking filters.

A very high performance single-channel VCA for the most demanding applications, the ProCircuit SSI2161 offers industry-leading lowest-noise, and a mode control to optimize noise vs. distortion performance. All at low-cost and in a 10-lead SSOP package. The SSI2161 is a versatile VCA building block for high-performance audio applications

The Electric Druid VCLFO 10 is a simple-to-use 0-5V voltage-controlled LFO chip with many more features than your average LFO. For a start, it can produce 16 different waveforms, in two banks of eight, including a wandering random wave and a noise source. Waveforms can be further shaped by the Wave Distort feature.

Holtek Chorus/Vibrato chip for robot voice and pitch shifter circuits. 18-pin DIP

The Elec Druid STOMPLFO 8-pin tap tempo LFO is perfect for smaller environments like pedals. It can replace the typical dual op-amp Schmitt trigger/integrator LFO design. It uses Pulse Density Modulation (PDM) instead of Pulse Width Modulation (PWM) for the output. This enables the output frequency to be much higher (2MHz instead of 10's of KHz) and that means simple RC filters can smooth the output easily without losing any waveform detail. DIP8.

The AUDIOMETER chip is a one-chip LED bargraph driver for building audio meter displays. You can simply feed it an audio signal and a +5V supply and it does the rest. The application circuit is very straightforward. It also provides an optional 'Peak Hold' LED which shows the maximum level reached above the main display of instantaneous level.

A pair of SRAM chips for use in the 4 second Digital Delay project. The 23LC1024-I/P is a 128KByte RAM chip with an SPI serial interface. Two of these chips are used in the DigiDelay project to produce up to 4 seconds of delay with 16-bit data and a 32KHz sample rate.

Holtek digital reverb. DIP24.

BBD, 1024 stages, DIP8. Made by XVive.

256 stage low noise BBD. Wide dynamic range and low distortion characteristics. The MN3009 provides a signal delay of up to 12,8msec and is particularly suitable for vibrato or chorus effects. Made by XVive.

The FatKeys SSI2164 is perhaps the most flexible VCA available, with four independent channels for lowest cost-per-Vapprox. The user-selectable mode control allows Class A, AB, or intermediate biasing, and current inputs and outputs provide great design freedom. Ideal for voltage-controlled filters.

Vintage, obsolete, NOS BBD chip.

A one-chip solution for clock generation and control with MN3205 and MN3208 type BBD chips. DIP28.
