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 μV offset voltage, 0.2 μ
V/degC offset voltage drift and <1 μs 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 ±2.25 V to ±18 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 μV offset voltage, 1 μV/degC offset
voltage drift and 400 nVpp frequency noise. AC specifications include 18 MHz
GBW, 22 V/μs slew rate and 0.0004 percent total harmonic distortion (THD) at
1 kHz.
The OPA827 operates over a ±4 V to ±18 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.
