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.
The novel topology also allows the second amplifier to be used for bidirectional operation, high/low current ranging or high voltage level translation.
The LTC6103 features outstanding performance: maximum input bias current is 170nA and the maximum input offset voltage is 450uV.
This precision performance allows the part to resolve very small currents and still operate over a large dynamic range.
The LTC6103 can withstand voltages up to 70V, a valuable feature when power supply failures or catastrophic load changes can lead to voltage fly back conditions.
With a response time of 1us, the LTC6103 is ideal for automatic power shutdown when sensing fault conditions.
Gain for each device is set by two resistors, and as the gain resistors are the primary determinants of accuracy, precision resistors allow for accuracy better than 1%.
"The LTC6103 builds on our existing family of precision, fast and flexible current sense devices", says Mike Kultgen, Design Manager for Linear Technology.
"Having a second integrated current sense amplifier increases the usefulness of this part by much more than a factor of two".
The LTC6103 is in full production, with prices starting at US $1.66 each in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
