Op Amps Developed Using TI's New 36-V Bipolar SiGe Process

	
    DALLAS, Nov. 22 /Xinhua-PRNewswire/ -- Texas
Instruments Incorporated (TI) (NYSE: TXN) today introduced
two new precision operational amplifiers that combine
ultra-low noise with lower power, smaller package size and
higher bandwidth than competitive 36-V amplifiers. The
OPA211 and OPA827 enable breakthrough performance for test
and measurement, instrumentation, imaging, medical, audio
and process control applications. These are the first
devices developed using TI's groundbreaking BiCom3HV
complementary bipolar 36-V silicon germanium (SiGe)
process. (See http://www.ti.com/sc06209 )

    "The OPA211 and OPA827 represent a new class of
precision amplifiers and demonstrate TI's commitment to the
high-voltage industrial market," said Art George,
senior vice president of TI's high-performance analog
business. "These new amplifiers deliver extremely high
accuracy with significant improvements in power consumption,
bandwidth and package size characteristics, which will
enable next-generation performance in industrial
applications."

    The OPA211 is a bipolar-input operational amplifier
that achieves 1.1 nV/rtHz voltage noise and 80 MHz gain
bandwidth product (GBW) with a supply current of only 3.6
mA. The device provides 100 ¦ÌV offset voltage, 0.2
¦ÌV/degC offset voltage drift and <1 ¦Ìs settling time
for driving precision analog-to-digital converters in data
acquisition systems. It also offers rail-to-rail output
swing, which enhances dynamic range.

    The OPA211 operates over a ¡À2.25 V to ¡À18 V supply
range and is available in MSOP-8 or DFN-8 packages. The 3mm
x 3mm DFN package requires about 1/3 the area of a standard
SO-8 package. Bipolar op amps excel in limiting errors
related to offset voltage and are used in applications
where the source impedance is low.

    The OPA827 is a JFET-input operational amplifier that
combines outstanding DC precision with excellent AC
performance. DC characteristics include 4.5 nV/rtHz voltage
noise, 250 ¦ÌV offset voltage, 1 ¦ÌV/degC offset voltage
drift and 400 nVpp frequency noise. AC specifications
include 18 MHz GBW, 22 V/¦Ìs slew rate and 0.0004 percent
total harmonic distortion (THD) at 1 kHz. 

    The OPA827 operates over a ¡À4 V to ¡À18 V supply range
with a supply current of only 4.5 mA. The MSOP-8 package
represents a 50 percent reduction compared to SO-8
packages. JFET op amps offer very low bias current and are
suited for applications where source impedance is high.

    TI provides customers with a state-of-the-art signal
chain solution for precision applications:
analog-to-digital converters such as the ADS8505 and
digital-to-analog converters such as the DAC8811. The
OPA211 and OPA827 are optimized to work with TI's
TMS320(TM) high-performance DSP platforms and MSP430
ultra-low-power microcontroller family.

    Industry's First Complementary Bipolar 36-V SiGe
Process

    TI's BiCom3HV process focuses TI's state-of-the-art
manufacturing technology on the future needs of
high-voltage industrial applications. The process offers
high speeds with low noise, low power consumption and much
smaller packaging than previously available. The BiCom3HV
process is the first 36-V industrial process to utilize
SiGe, which leads to significantly faster transistors than
previously available. Excellent transistor matching along
with precision SiCr resistors delivers increased accuracy,
dynamic range and stability over the working temperature
range. 

    The reduction in transistor size is made possible by
using silicon-on-insulator (SOI) technology. The minimum
NPN transistor is up to 11 times smaller than those
available in the most advanced processes from the
competition. SOI also brings other advantages such as low
leakage currents and reduced interaction between
transistors.

    The BiCom3HV process is ideal for the next generation
of industrial voltage operational amplifiers (bipolar-input
and FET-input), instrumentation amplifiers, programmable
gain amplifiers and precision references.

    Availability and Packaging

    The OPA211 is sampling now, with volume production
scheduled for 2Q 2007. The device is available in DFN-8,
MSOP-8 and SO-8 packages and is priced at $3.45 in
1,000-piece quantities (suggested resale pricing). 

    The OPA827 is sampling now, with volume production
scheduled for 2Q 2007. The device is available in MSOP-8
and SO-8 packages and is priced at $5.75 in 1,000-piece
quantities (suggested resale pricing). 

    All devices are specified for operation from -40C to
+125C. For more information on TI's complete analog design
