Low offset 18MHz CMOS

Linear Technology Corporation has launched a new class of CMOS amplifiers with voltage noise like bipolar amplifiers. Generally known for their low input bias current, CMOS amplifiers are inherently noisier than bipolar designs. The LTC6241 dual and LTC6242 quad amplifiers address this fundamental performance trade off. With low noise of 550nVp-p in the 0.1 to 10Hz region, these amplifiers offer a three-fold reduction in voltage noise over existing CMOS amplifiers. Thisperformance, previously unattainable from a CMOS amplifier, delivers maximum signal resolution in a wide variety of high-end instrumentation, medical and communication applications requiring high impedance inputs.


Not only do these amplifiers minimize a crucial error source, voltage noise, but they also provide excellent DC precision. The LTC6241 and LTC6242 feature 1pA bias current and less than 125uV input offset voltage. Offset voltage drift is guaranteed under 2.5uV/°C while the high voltage gain of 124dB keeps system error to a minimum. The 18MHz gain bandwidth and 10V/us slew rate at a low supply current of 2.2mA max per amplifier make these amplifiers very versatile and suited for a wide variety of signal processing applications.
