THAT Showcases New Analog Engine

THAT Corporation's new low-power THAT4315 Analog Engine (Booth 2687). Easily configured to handle almost any dynamics or gain control application, the THAT4315 delivers excellent audio performance as a customizable, battery-friendly building block that saves time and money.

Using the new THAT4315, audio design engineers can realize almost any analog audio processing function thanks to the chip's Blackmer voltage-controlled amplifier (VCA) and high-accuracy, wide-range rms level detector. The VCA provides a wide control range of 100 dB, total unity-gain noise of -98dBV, and is pre-trimmed for typical distortion of only 0.07-percent. To top it off, the THAT4315 was designed from the ground up for battery operation, drawing a meager 1.6mA from a single 5V supply.

The THAT4315's combination of superior sonic quality, low-power operation, and affordable price raise the audio performance bar in battery-operated devices. Using their own designs or drawing from THAT Corporation's extensive library of application and design notes, engineers can configure the THAT4315 as compressor, expander, limiter, gate, noise reduction system, automatic microphone mixer, AGC, remote gain control, or any number of the common signal processing functions required by today's portable audio products. In applications from wireless microphones, monitors, and speakers to portable mixing consoles, recorders, and effects boxes, the THAT4315 provides a low-power, low-cost, high performance solution for next-generation designs.
