STMicroelectronics Introduces Lowest Noise Operational Amplifier for 
High-End
Medical and Instrumentation Applications
Ultra low noise, wideband op-amp in tiny package will improve performance of
high-speed data acquisition systems
GENEVA, April 13 /PRNewswire-FirstCall/ -- STMicroelectronics (NYSE: STM)
today announced availability of a new, ultra low noise, wide bandwidth
operational amplifier -- the TSH300 -- which is intended for high end
industrial, medical and instrumentation applications. Its typical noise 
value
(Equivalent Input Noise Voltage) of 0.65nV/sqrtHz is thought to be the 
lowest
in the industry for a wide band amplifier in the tiny SOT23-5L package, or 
in
SO-8.
    The device is the eighth new product in ST's high-end operational
amplifier family to be launched in the past 12 months -- each device in the
family offers a unique performance feature, such as the ultra low noise of 
the
TSH300, in addition to the wide bandwidth of all the devices.
    The TSH300 features low input noise of 0.65nV/sqrtHz, coupled with a
bandwidth of 200MHz at a gain of 5V/V (GBP=1GHz). With its high slew rate of
230V/micros and very good linearity (SFDR of 55dBc, measured with a 10MHz
output sine wave of 2Vp-p into a 100 ohm load), the TSH300 is a perfect
component in analog-to-digital converter (ADC) interface applications. Its
ultra low noise performance and wide bandwidth have been achieved using a 
very
fast 0.25 micron complementary bipolar manufacturing process. The TSH300 is
ideal for use in systems such as sensor preamplifiers and ultrasound 
imaging,
where very small and very fast signals need to be amplified with high gain,
without adding significant noise and while preserving a very good
signal-to-noise ratio.
    The amplifier is stable for gains greater than 5, enabling it to be used
at high gain values for small amplitude input signals. Its topology allows 
it
to be used in inverting mode with excellent frequency response, providing 
good
performance when combining two devices in the differential configuration.
Voltage feedback architecture allows the use of reactive elements in the
feedback loop, as required for many filter topologies. It operates from 4.5V
to 5.5V on either single or dual supplies.
    The TSH300 is specified for operation over the -40 degrees C to +85
degrees C temperature range, and is available in volume now in SO-8 and the
space saving SOT23-5L packages, priced at $1.50 each for quantities up to
5,000 unit

Anche se ci fosse è una non-notizia.
Quel componente è sul mercato almeno dall'autunno scorso (quella è la data 
di pubblicazione del data sheet) e si compra un po' dappertutto in giro per 
il mondo per meno di due dollari.

Nemmeno tre dollari !
