The Sound Semiconductor DAB2130 is a pre-soldered DIP converter for the SSI2130. This board features the SSI2130 and two decoupling caps for the V+ and V- inputs. The pinout is labelled on the board and matches the QFN pinout. This adapter features a 32 pin DIP base with a .600 in. width. The pins are standard male headers so 2.54mm female headers are recommended for socketing the board. For the standard QFN version, please see P-Q-SSI2130.

The first new VCO IC in decades, and worth the wait! The FatKeys™ SSI2130 Voltage Controlled Oscillator provides beautiful triangle, sawtooth, pulse, and square waveforms with unprecedented temperature stability; and adds an on-chip mixer, low distortion sine wave generator, through-zero FM/PM capability and more in an ultra-compact PCB footprint.

The SSI2130 is a new-generation voltage controlled oscillator subsystem for high-performance electronic musical instruments. A complete analog synthesizer voice can be constructed at low cost with one or more SSI2130’s, a SSI2144 or SSI2140 Voltage Controlled Filter, and SSI2162/2164 VCA(s).

Outputs include triangle, sawtooth, pulse, and open collector square wave with direct voltage outputs. An on-chip five channel mixer with linear control VCA’s sums triangle, saw, and pulse waveforms plus two independent auxiliary inputs into a single current output.

A precision analog multiplier provides unprecedented temperature-compensation, and careful attention was paid to improvement of triangle and sawtooth waveforms compared to previous-generation VCO IC’s.

An accurate and temperature-stable sine wave can be produced by the internal sine shaper circuit. Through-zero FM and PM can be achieved with an external comparator, op amp, and several discrete components.

Optional trims are provided for expo scale and high frequency tracking, but can be automated by CPU-calibrated systems. The SSI2130 requires minimal external components and is available in a diminutive 4x4mm QFN package.
