TI op amps set new performance and power benchmarks for pro audio and prosumer audio systems
Amplifiers deliver industry's best combination of noise, distortion, bandwidth and low power consumption
DALLAS, Oct. 23, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today introduced two bipolar-input audio operational amplifiers (op amps) that provide unmatched noise, distortion and bandwidth performance while dissipating a mere 1.5 mA. The power-efficient, dual-channel OPA1662 and quad-channel OPA1664 enable system designers to develop the next generation of professional and prosumer audio equipment capable of producing crisp, clean "true to the original recording" sound quality. These op amps are targeted at USB and FireWire audio systems, analog and digital mixers, portable recording systems, and other applications that require the highest noise performance combined with low power consumption. For information or to order samples, visit http://www.ti.com/opa166x-pr.
Key features and benefits of the OPA1662andOPA1664
-- Best noise/distortion performance: Low 3.3-nV/rt Hz noise density with
an ultra-low total harmonic distortion plus nose of 0.00006 percent at 1
kHz enables the design of much higher performance audio equipment than
previously thought possible.
-- Lowest power consumption: Low quiescent current of 1.5 mA per channel
allows designers to stay within system power budgets while offering
unmatched sound reproduction.<s> </s>
-- Higher signal integrity: A wide gain bandwidth of 22 MHz and slew rate
of 17 V/us provide higher signal integrity and faster response to a
wider range of input signal frequencies.
-- Widest supply range: Operating range of +/-1.5 V to +/-18 V or +3 V to
+36 V provides excellent dynamic performance over a wide choice of
loads.
System designers can build an audio signal path by combining the OPA1662 or OPA1664 with the PCM1792A 24-bit, 192-kHz sampling, stereo audio digital-to-analog converter (DAC).
Tools and support
The OPAMPEVM universal op amp evaluation module (EVM) is available to accelerate the development of audio equipment using the OPA1662 and OPA1664 for a suggested retail price of US$5. The Active Filter Designer tool can help system designers implement an op amp filter design. TINA-TI SPICE models and reference designs are also available today for the OPA1662 and OPA1664 op amps.
Availability, packaging and pricing
The dual-channel OPA1662 is available today in SO-8 and MSOP-8 packages for a suggested retail price of US$0.95 in 1,000-unit quantities. The quad-channel OPA1664 is available in SO-14 and TSSOP-14 packages for a suggested retail price of US$1.45 in 1,000-unit quantities.
