New York, NY (November 6, 2012)—THAT Corporation introduced two new products—the THAT 1583 Differential Audio Preamplifier IC and the THAT 4316 low-voltage, low-power Analog Engine—at AES in San Francisco this past weekend.
The THAT 1583 is a current-feedback amplifier suitable for differential microphone preamplifier and bus summing applications. It improves on THAT's 1510 and 1512 by reportedly offering a more versatile configuration that can yield lower noise at low gains, lower distortion overall, and higher slew rate.
In addition to analog-controlled applications, the 1583 is designed to mate with THAT's series of Digital Preamplifier Controller ICs.
The THAT4316 is a single-chip Analog Engine that incorporates a class-AB voltage-controlled amplifier (VCA) and true-RMS-responding level detector. The 16-pin QSOP part is aimed at battery-operated audio applications including companding systems for wireless microphones, wireless instruments, and in-ear monitors, as well as dynamics processors of all types. The 4316 operates from a single supply voltage down to 2.7V, drawing only 1.2mA at 3.3V.
