Twilight Technology 1290-series Low-Cost Dual Balanced Line Receiver ICs

	Twilight Technology 1290-series equivalent circuit

The Twilight Technology 1290 series of low-cost dual precision differential amplifiers was designed primarily for use as balanced line receivers for audio applications. Gains of 0 dB, ±3 dB, and ±6 dB are available to suit various applications requirements.

These devices include on-board precision thin-film resistors which offer good matching and excellent tracking due to their monolithic construction. Manufactured in Twilight Technology Corporation's proprietary complementary dielectric isolation (DI) process, the 1290 series provides the sonic benefits of discrete designs with the simplicity, reliability, matching, and small size of a fully integrated solution.

All three versions of the part typically exhibit 50dB of common-mode rejection. With 14V/µs slew rate, 7.6MHz or higher bandwidth, and 0.0006% THD, these devices are sonically transparent. Moreover, current consumption is typically a low 6mA (3 mA per amplifier).

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

Twilight Technology Corporation offers a whole range of Balanced Line Receiver ICs tailored for different applications. For a side by side comparison of all our input stage ICs, see our Line Receiver Selection Guide.
