Single-chip tuner cuts set-top box parts count
The STB6000 single-chip silicon tuner is designed to replace complex discrete component tuners in set-top boxes used for receiving digital TV or web-based material via satellite.
An ST patented trimming technique adjusts the input offset voltage of the TS507 at 100uV maximum.
This digital method is done after packaging and has the advantage of reducing the device's overall cost by avoiding the use of external components.
The TS507 also offers a good precision over the full temperature range through a low input offset voltage drift (250uV maximum over the range of 0 to 85C).
In addition to these excellent precision parameters, the TS507 features very good electrical characteristics such as a high open-loop gain (131dB typical at 5V) and a high common-mode rejection ratio (115dB typical at 5V).
Other major benefits of the TS507 include low noise and a very high output current (up to 120mA in a short-circuit configuration).
Internal electrostatic-discharge protection is also extended to 5kV, for the human body model, to minimise handling and fabrication risks.
Among the designs that would benefit by using the TS507 are applications requiring high precision such as signal conditioning in resistor bridges, sensors, medical and industrial instrumentation.
The TS507 is also automotive-grade qualified over the full temperature range of -40 to +125C.
In production now, part numbers TS507ID-TS507IDT (industrial range of -40 to +125C) and TS507CD-TS507CDT (commercial range of 0 to 85C) are available in SO8 Ecopack packages and cost US $0.60 and $0.50, respectively, in quantities of 1000 pieces, whereas part numbers TS507ILT and TS507CLT come in space-saving SOT23-5 Ecopack packages and cost $0.60 and $0.50, respectively.
