Abletec.com C1 Datasheet (2026)

The low THD+N and high damping factor provide the transparent, uncolored sound necessary for critical mixing and mastering.

Unlike generic Class-D controllers that utilize fixed external clock ramps, the Abletec C1 employs an advanced phase-shift self-oscillating topology. This configuration forms a high-order global feedback loop around the output LC filter. It dynamically corrects non-linearities caused by power supply ripple, output stage dead-time, and inductor core saturation. 2. Configurable Dead-Time Control

: High-current totem-pole outputs designed to switch external power stages swiftly.

Its compact size makes it ideal for mounting directly inside speaker cabinets to create active monitors. abletec.com c1 datasheet

Keep AC mains wiring strictly separated from the low-level audio input cables to prevent 50/60 Hz hum from bleeding into the audio path.

Exceptionally low, yielding a high damping factor for tight speaker cone control. Electrical and Thermal

) immediately adjacent to pins 14 and 15 to minimize high-frequency parasitic inductance loops. The low THD+N and high damping factor provide

Here are two options:

One of their key product lines was the ALC (Audio Line Combination) Series, which integrated advanced Class D power amplifiers with their ZVS (Zero Voltage Switching) power supplies. These modules were designed for OEMs and featured Energy Star compliance, high efficiency, and built-in protections.

Operating the IC beyond these absolute maximum values can cause permanent silicon degradation or immediate catastrophic failure.

Place an array of thermal vias directly beneath the SOP-16 package to conduct heat away to inner ground planes.

SOP-16 replacements bought from third-party marketplaces often ship without antistatic shielding. Because the high-impedance inputs are sensitive to ESD, handle the chips using grounded workspace protocols. Procurement and Document Sourcing Abletec ALC1000 any experience? - diyAudio

Note: As this component is often found on third-party marketplace listings, ensure proper handling in antistatic packaging during installation.
