New process boosts analogue performance
A new high-performance manufacturing process promises to improve the performance of analogue products such as ADCs, DACs, op amps and power amplifiers
Designers of high-performance systems, such as test and measurement, medical instrumentation, industrial process control and communications, will benefit from the lowest CMOS noise performance in the industry, higher levels of integration and high-volume 200mm wafer production offered by the new technology.

'The release of the HPA07 process illustrates TI's ongoing commitment to the high-performance analogue market.
This technology will enable our analogue engineers to create a leadership portfolio of high-performance analogue solutions that will surpass customers' precision and integration requirements', said Lou Hutter, Manager of TI's mixed-signal technology development.
HPA07 incorporates high quality passive components critical to enabling the efficient design of high-performance analogue products: metal-to-silicide (very low voltage coefficient) precision capacitors without hysteresis, and very precise, laser-trimmable thin-film resistors.
The unique process capabilities and rich feature set of HPA07 will allow TI's analogue engineers to develop standalone circuit blocks and combine diverse functions to create highly-integrated functional circuits with unequalled precision analogue specifications.
The combination of a precision capacitor with less than 5ppm/V voltage coefficient, 1kohm/square SiCr resistors, 5V analogue CMOS with low 1/f noise and 30V drain extended CMOS has provided designers with high-precision components optimised for a wide range of new product designs.

TI currently has over 30 products in development on HPA07 that will take advantage of its increased analogue performance.
The precision capacitor characteristics will make it possible to design successive approximation data converters with superior integral nonlinearity (INL).
The SiCr resistor will enable the integration of eight 16bit R2R-type DACs in a 48-lead TSSOP.
Precision instrumentation amplifiers can also be designed to utilise the precise matching and laser trim of SiCr resistors.
The first product to be manufactured using the HPA07 process, a precision operational amplifier, is available today from stock.
The OPA300 is a low-noise, high-speed op amp designed to interface with high-speed 16bit ADCs, such as TI's ADS8401 - a 16bit, 1.25Msample/s ADC.
The 1/f noise of the OPA300 is 20% better than equivalent designs on TSMC's analogue CMOS.
The component matching and stability over time offered by HPA07 enables products like the OPA300 to achieve better accuracy.
The HPA07 process, developed in TI facilities in Dallas, Texas, with contributions from a worldwide TI engineering team, is fully qualified.
A 3.3V version of HPA07 will be available for designs in 3Q 2003.
This process will offer all of the excellent characteristics of the 5V version.
