Maxim introduces the MAX9617/MAX9618, zero-drift, rail-to-rail operational amplifiers. Packaged in 6-pin SC70 (single) and 8-pin SC70 (dual) packages, these devices are designed to operate from 1.8V to 5.5V supplies. The MAX9617/MAX9618 are ideal for a wide variety of portable medical applications. The ICs achieve both a 10µV (max) input-offset voltage and an input-voltage noise of 1µVP-P from 0.1Hz to 10Hz. Designed to have minimal 1/f noise, the devices facilitate accurate low-frequency measurements and allow for optimization of active filter designs. Moreover, the precision of the MAX9617/MAX9618 will not degrade with time and temperature, as they both feature 5nV/°C input-offset-voltage drift. The MAX9617/MAX9618 are fully specified for operation over the -40°C to +125°C automotive temperature range.
