Description

EVB2130-R6-B – Bare PCB (SSI2130 pre-soldered)

The SSI2130 offers unprecedented performance and features, but its ultra-compact QFN package can present prototyping challenges. The EVB2130 eases evaluation by providing a PCB that allows comprehensive exploration of capabilities. The EVB2130R6-B is a blank board with only the SSI2130 pre-soldered. You source the rest of the components yourself, which are all through-hole for easy construction and experimentation. An on-board +5V regulator and 2.5V reference simplify external power connections, and there are controls for mixer control, PWM, and VCO setup. Switches ease selection of saw ramp direction plus Through-Zero and Pulse Modulation.

EVB2140-LPR1-B – Bare PCB (SSI2140 pre-soldered)

The SSI2140 is packaged in a low-pitch 20-lead SSOP that can make prototyping a challenge. To allow easy and quick evaluation of low-pass filter functionality, SSI have developed the EVB2140LP that brings out all of its powerful features and capability. The EVB2140LP-B is a blank board with only a SSI2140 pre-soldered. You source the rest of the components yourself, which are all through-hole for easy construction and experimentation. Audio inputs and outputs are provided along and terminals are arranged around the board’s perimeter. Frequency cut-off, resonsance, unity-gain overdrive, pole switching, and three Q-compensation schemes are selectable. The on-chip tempco or an external resistor can be optionally be activated, and an onboard reference allows precise Q and Frequency control.

EVB2190-R1-B – Bare PCB (SSI2190 pre-soldered)

The SSI2190’s tight-pitch 24-lead SSOP package is great for compact PCB layouts, but prototyping can be a challenge. To expedite the development process, we offer the EVB2190R1 that allows evaluation of the SSI2190’s awesome capabilities. If you’ve dreamed up a really unique application that the EVB2190R1 doesn’t support, then consider the DAB2190 Dip Adapter for quick protoboard development. The EVB2190R1-B is a blank board with only a SSI2190 pre-soldered. You source the rest of the components yourself, which are all through-hole for easy construction and experimentation. Headers provide individual access to each channel’s differential inputs, options for CV control via onboard pots or external source are available, and a variable control reference.
