The DACO160EVK (Evaluation Kit) is a small printed circuit board (PCB) containing the digital audio-controlled oscillator (based on an ST Microelectronics micro-controller) and some supporting circuits for showcasing the sound of its internal square, saw and sine oscillators. The DACO160EVK does everything its predecessor, the ACO160EVK did, but with higher performance and reliability. It also features a 2-pole LPF on the saw and square waves with optional envelope modulation.
