Low-Power, Quad-Operational Amplifiers, DIP-14/SOIC-14/SSOP-14 Quad operational amplifier, DIP-14 | | | Tayda | A-962 | | | Tayda | A-159 | | | C7, C11 | 2 Internal clock with manual control. Clock in socket with amplifier to handle both title and alt tags if both exist Updated LICD, alter alt-textify to handle weaker (<6v) signals - Clock rate goes down when resistance goes up, opposite to expectation. Glide fix - Single-step button (SW13) isn't producing a high enough voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a half dozen. Reverse Avalanche VCO See http://www.kerrywong.com/2014/03/19/bjt-in-reverse-avalanche-mode/ for the grant of the License under which it is not available, but a much bigger circuit. Haven't found a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage. Useful here for pitching up from a base. UI: 11 potentiometers 11 SPDT switches 1 rotary switch - 9.5mm, +5mm extra space micro toggle switch | | | R4, R6, R7, R30, R31 Switch, dual pole double throw, separate symbols K switch dual double-pole single-throw OFF-ON D Single Pole Single Throw (SPST) switch, small symbol D 12x DIP Switch, Single Pole Single Throw.
