Description

The THAT 124x series of precision differential

20MHz bandwidth, and 0.0006% THD. Both sur-

face-mount and DIP packages are available.

amplifiers are designed primarily for use as audio

balanced line receivers. Gains of 0 db, -3 dB, and

-6 dB are available to suit various applications re-

quirements.

The THAT 124x family are laser-trimmed to

obtain the precision resistor matching needed for

high CMR performance. Fashioned in THAT Cor-

poration's proprietary dielectric isolation (DI)

process, the THAT 124x series provides the sonic

benefit of discrete designs, with the compact size,

reliability, matching, and thermal tracking of a

fully integrated solution.

The THAT 1246 is drop-in compatible with

the Burr-Brown INA137 and Analog Devices

SSM2143, while the THAT 1240 is drop-in com-

patible with the SSM2140.

All devices exhibit 90 dB of typical com-

mon-mode rejection, slew rates of 12 V/ms, a
