New Audio Processor IC Targets Wireless Applications

THAT 4320
Analog Engine®
Dynamics Processor IC

New York, October 8, 2003 - THAT Corporation announces availability of the THAT4320S, a single-chip Analog Engine® optimized for low-voltage, low-power operation. Incorporating a high-performance voltage controlled amplifier (VCA), rms-level sensor, and four opamps, the surface-mount part is aimed at battery-operated audio applications like wireless microphones, wireless instruments and personal monitors. It operates down to +4.5Vdc, drawing only 3.7mA.

According to THAT's president, Les Tyler, "the 4320 offers improved performance and value over THAT's own 4311 low-voltage dynamics processor. The 4320 operates on a single supply up to 15Vdc, making it useful in line- as well as battery-operated products. The VCA is pre-trimmed at wafer stage to deliver low distortion without further adjustment. And, one opamp is quiet enough to be used as a microphone preamp."

Gary Hebert, THAT's chief technical officer added "What really sets this IC apart is the transparent sound of its Blackmer™ VCA coupled with its accurate, wide-range true-rms level detector. The 4320 is useful in battery-powered mixers, compressor/limiters, ENG devices and other portable audio products. This is a highly integrated IC -- it even contains an on-board PTAT reference to generate thermally-compensated control voltages for thresholds and gain settings."

Priced at $5.33 in 1k quantities, and packaged in a 28-pin QSOP, the THAT 4320 is economical in cost and PCB real estate. Follow these links for additional information on the 4320, to download a 4320 datasheet, or to learn about THAT Corporation's other ICs.
