詳細(xì)描述

THAT1583 是一款高性能多功能音頻前置放大器，適用于麥克風(fēng)前置放大器和總線求和應(yīng)用。更重要的是，它被設(shè)計為可與以下任一者配合使用：THAT5171 以 1dB 步長對增益設(shè)置進行數(shù)字控制；或 THAT5173 步長為 3dB。

前置放大器在 +/- 18V 電壓下運行，無需輸入板即可接受專業(yè)音頻電平 (+28dBu)。將此與 60dB 增益下僅 1.9nV/rtHz 的噪聲相結(jié)合，您就擁有了一個真正高性能的前置放大器。

THAT1583 的差分輸出簡化了與 A/D 轉(zhuǎn)換器等差分輸入設(shè)備的連接。需要時，設(shè)計人員可以自由優(yōu)化輸出差分放大器以適應(yīng)特定應(yīng)用。

THAT1583 采用 4x4mm QFN16 封裝，占用的電路板空間非常小。它還與 THAT1570 引腳兼容，因此您可以使用相同的布局優(yōu)化價格和性能。

The THAT1583 is a high-performance versatile audio preamplifier suitable for microphone preamp and bus summing applications. What's more it has been designed to work with either: the THAT5171 to enable digital control of the gain setting in 1dB steps; or the THAT5173 in 3dB steps.

Operating on maximum of +/- 18V supplies the pre-amplifier accepts pro-audio levels (+28dBu) without an input pad. Combine this with just 1.9nV/rtHz noise at 60dB gain and you have a truely high performance pre-amplifier.

The THAT1583's differential output simplifies connections to differential input devices such as A/D converters. When required, designers are free to optimise the output differential amplifier to suit specific applications.

Packaged in 4x4mm QFN16 the THAT1583 takes up very little board space. It's also pin compatible with the THAT1570 so you can optimise price and performance with the same layout.
