THAT 1290-series
equivalent circuit
|
|
|
The THAT 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 THAT
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.
THAT 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.
