PRODUCT DESCRIPTION
PRODUCT HIGHLIGHTS
The BiFET series of precision, monolithic FET-input op amps are fabricated with the most advanced BiFET and laser trimming technologies. The AD542, AD544, AD547 series offers bias currents significantly lower than currently available BiFET devices, 25 pA max, warmed up. In addition, the offset voltage is laser trimmed to less than 0.25 mV on the AD547L, which is achieved by utilizing Analog Devices’ exclusive laser wafer trimming (LWT) process. When combined with the AD547’s low offset drift (1 V/°C), these features offer the user performance superior to existing BiFET op amps at low BiFET pricing. The AD542 or AD547 is recommended for any operational amplifier application requiring excellent dc performance at low to moderate cost. Precision instrument front ends requiring accurate amplification of millivolt level signals from megohm source i……
