Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
Using a unique architecture, the LTC6244 boasts low noise of 8nV/(rt)Hz while maintaining an input capacitance of only 2.1pF.
Very low input capacitance is critical at high frequencies to maintain high input impedance and low noise performance.
"This breakthrough performance, previously unattainable from a CMOS amplifier, delivers maximum signal resolution in a variety of applications such as large or small area photodiode, transimpedance and charge coupled amplifiers, precision integrators and filters", says Design Manager, Dan Tran.
The LTC6244 has applications in instrumentation, medical, industrial and communications systems.
In addition to minimising the voltage gain error, the LTC6244 provides excellent DC precision.
It features 1pA bias current and less than 100uV input offset voltage at 25C.
Offset voltage drift is guaranteed under 2.5uV/C while the high voltage gain of 120dB keeps system error to a minimum.
The 50MHz gain bandwidth and 40V/us slew rate at a low supply current of 7.4mA maximum per amplifier makes this amplifier extremely versatile and perfect for use in a wide variety of applications.
Operating from supply voltages as low as 2.8V and up to 12V (HV version), the amplifier's output swings rail-to-rail.
The LTC6244 dual op amp is offered in tiny 3 x 3mm DFN and 8-pin MSOP packages.
Fully specified to operate over the commercial, industrial, and high temperature ranges, 1000-piece pricing starts at US $1.65 each. Request a free brochure from Linear Technology Corp ...
