Linear Technology has added to its family of low noise, precision CMOS op-amps. With a gain bandwidth of 50 MHz and input characteristics that challenge precision bipolar amplifiers, the company says its new LTC6244 dual op-amp offers breakthrough performance that no other amplifier can deliver.
Guaranteed offset voltage is only 300 µV max over the full industrial temperature range, which rivals the 25°C spec for other amplifiers in its class.
Using a unique architecture, the LTC6244 boasts low noise of 8 nV/sq.rt.Hz while maintaining an input capacitance of only 2,1 pF. Very low input capacitance is critical at high frequencies to maintain high input impedance and low noise performance. The LTC6244 has applications in instrumentation, medical, industrial and communications systems.
In addition to minimising the voltage gain error, the LTC6244 provides superior DC precision. It features 1 pA bias current and less than 100 µV input offset voltage at 25°C. Offset voltage drift is guaranteed under 2,5 µV/°C while the high voltage gain of 120 dB keeps system error to a minimum. The 50 MHz gain bandwidth and 40 V/µs slew rate at a low supply current of 7,4 mA max per amplifier makes this amplifier versatile.
It operates from supply voltages down to 2,8 V and up to 12 V (HV version), the amplifier's output swings rail-to-rail. The LTC6244 dual op-amp is offered in 3 x 3 mm DFN and 8-pin MSOP packages, specified over the commercial, industrial, and high temperature ranges.
