Hot-selling and scarce AD547JH High Performance, BiFET Operational Amplifiers CAN-8 spot stock

​Product Descriptions

The BiFET series of precision, monolithic FET-input op ampsare fabricated with the most advanced BiFET and laser trimming technologies .  The AD542, AD544, AD547 series offersbias currents significantly lower than currently available BiFETdevices, 25 pA max, warmed up .

In addition, the offset voltage is laser trimmed to less than0.25 mV on the AD547L, which is achieved by utilizing AnalogDevices’ exclusive laser wafer trimming (LWT) process .  Whencombined with the AD547’s low offset drift (1 µV/°C), thesefeatures offer the user performance superior to existing BiFETop amps at low BiFET pricing .

The AD542 or AD547 is recommended for any operational amplifier application requiring excellent dc performance at low tomoderate cost .  Precision instrument front ends requiring accurate amplification of millivolt level signals from megohm sourceimpedances will benefit from the device’s excellent combinationof low offset voltage and drift, low bias current and low 1/fnoise .  High common-mode rejection (80 dB, min on the“K”and“L” grades) and high open-loop gain, even under heavyloading, ensures better than“12-bit” linearity in high impedance buffer applications .
