Low-noise high-speed op
amp drives 16bit systems
The OPA300 voltage-feedback op amp is the first product to be manufactured using TI's new HPA07 precision analogue process
High bandwidth (180MHz), low noise (3nV/(rt)Hz), fast settling (150ns to 0.0015%) and low harmonic distortion (0.003%) make the OPA300 ideal for driving the industry's highest performance 16bit analogue-to-digital convertors (ADCs), such as TI's ADS8401 and ADS8402 - the industry's first 16bit SAR data convertors to surpass 1Msample/s (1.25Msample/s).

Webcast to address wireless power optimisation
Texas Instruments and Avnet Electronics Marketing will present a live Analog eLab webcast on 'Optimising power in low-power wireless systems' on 12th April 2006
'The OPA300 provides customers with a true 5V single supply solution for driving high-speed SAR ADCs without compromising performance or using a negative power supply', said Tadija Janjic, Strategic Marketing Engineer of TI's high-performance amplifier products.
'This 'complete solution' approach from TI gives designers a cost-effective, high-performance data acquisition system'.
Single-supply applications will benefit from operation on 2.7V (+/-1.35V) and 5.5V (+/-2.75V).
Power-sensitive applications will benefit from a shutdown function that reduces quiescent current (7mA) to 2uA.
The OPA300 features rail-to-rail output swing (100mV typically) and wide common-mode range.
In addition to buffering 16 and 18bit ADCs, the OPA300 is well suited to low-noise preamplifier, IF/RF amplifier and active filtering applications.
It is specified over the extended industrial temperature range of -40 to +125C.
TI's HPA07 process offers the industry's lowest CMOS noise performance, very precise thin-film resistors, higher levels of integration and high-volume 200mm wafer production.
TI currently has over 30 products in development on HPA07 that will take advantage of its increased analogue performance.
The OPA300 comes in SO-8 packages, and is available now from TI and its authorised distributors.
SOT23-6 packaging will be available in Q3 2003.
Suggested resale pricing starts at $1.25 in 1000-piece quantities.
