Differential amplifier drives SAR ADCs
directly
Linear Technology has announced the LT1994, the latest fully differential amplifier for driving high-resolution analog-to-digital converters.
Linear Technology has released the LT1994, the latest fully differential amplifier for driving high-resolution analogue-to-digital convertors With guaranteed operation down to 2.375V and rail-to-rail outputs, it is the industry's only differential amplifier that can directly drive 2.5 and 3V SAR ADCs without the need of a negative supply

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.
Achieving -94dBc harmonic distortion at 1MHz and an extremely low voltage noise of 3nV/(rt)Hz, the LT1994 provides the widest dynamic range on the lowest supply voltages.
"The trend toward lower voltage, single supply high performance analogue-to-digital convertors has created the need for differential amplifiers that can operate on a common supply rail without compromising performance", said Erik Soule, General Manager of Linear Technology's signal conditioning product line.
"The LT1994 addresses this need, providing customers with a true single supply solution for driving 16bit ADCs".
Ideally suited for driving 14 to 16bit ADCs such as the LTC1403A-1 and LTC1867L, the LT1994 is an excellent choice for general-purpose differential signal amplification, level shifting, single-ended to differential conversion and differential line driver/receiver applications in industrial, instrumentation and medical applications.
In addition to low noise and low distortion characteristics, the LT1994 is capable of sourcing and sinking up to 85mA.
It draws approximately 14mA supply current and features a shutdown pin that reduces consumption to 300uA.
The LT1994 is specified for operation from 2.375 to 12.6V.
Available in commercial and industrial temperature grades, it is offered in the MSOP-8 and DFN-8 packages.
Pricing starts at $1.65 each in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
