Dual Balanced Line Receiver ICs

DESCRIPTION

The THAT 1290 series of low-cost dual precision differential amplifiers was designed primarily for use as balanced line receivers for audio applications.

These devices include on-board precision thin-film resistors which offer good matching and excellent tracking due to their monolithic construction.

The 1290 series is available in a 16-pin QSOP package which features a very small footprint.

APPLICATIONS

• Balanced Audio Line Receivers
• Instrumentation Amplifiers
• Differential Amplifiers
• Precision Sum and Difference Networks
• M-S Matrices
• Precision Rectifiers
• Precision gain amplifiers
• Current Shunt Monitors
