2-Channel Digital Audio Preamplifier Controller

DESCRIPTION

The THAT 5263 is a 2-channel digital preamplifier controller intended for use with low-noise, analog, differential audio preamplifiers such as the THAT 1580 and 1583. The 5263 controls gain from 0dB to 51 dB in 3dB steps while preserving low noise and distortion. Operating from ±5V to ±17V analog supplies, it supports input signal levels as high as +29.6 dBu (at 0dB gain, ±17V supplies, and THAT1580) without an input pad. Used with a THAT 1580 preamplifier IC, equivalent input noise (EIN) at 51 dB gain is -128.3 dBu (20 Hz - 20 kHz bandwidth, 150-ohm source).

Each 5263 channel includes a zero-crossing detector to minimize glitches (zipper noise) during gain adjustments. A built-in timer forces a gain change if no zero crossing occurs within 24 msec of a gain-change command. A busy pin (BSY) allows synchronization of external events and the 5263's own GPOs with the zero-crossing detector.

The 5263 is controlled via an industry standard serial-peripheral interface (SPI) port. The part mates perfectly with the THAT 1580 and 1583 Differential Audio Preamplifier ICs. Together, these combinations provide high performance, space-saving solutions for digitally-controllable audio preamplifiers. However, the 5263 may also be used to control discrete pre-amplifiers.

APPLICATIONS

• Digitally controlled microphone preamplifiers

• Digitally-controlled instrumentation amplifiers

• Digitally-controlled differential amplifiers

• Audio mixing consoles

• Computer audio interfaces

• Audio distribution systems

• Digital audio snakes

• Audio recorders
