... In addition, the offset voltage is laser trimmed to less than 0. 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. ...

... Schottky protection diodes recommended for use with many older CMOS DACs are not required when using one of the BiFET series amplifiers. Figure 31a shows the AD547 and AD7541 configured for uni- polar binary (2-quadrant multiplication) operation. With a dc reference voltage or current (positive or negative polarity) ap- plied at pin 17, the circuit operates as a unipolar converter ...

... AD547 make it suitable for wide dynamic range log amplifiers. Figure schematic of a log ratio circuit employing the AD547 that can achieve less than 1% conformance error over 5 decades of current input 100 A. For voltage inputs, the dynamic range is typically for 1% error, limited on the low end by the amplifiers’ ...

... AD542/AD544/AD547 This particular log ratio circuit is free from the dynamic prob- lems that plague many other log circuits. The –3 dB bandwidth is 50 kHz over the top 3 decades, 100 nA to 100 A, and de- creases smoothly at lower input levels. This circuit needs no ad- ditional frequency compensation for stable operation from input current sources, such as photodiodes, that may have 100 pF of shunt capacitance ...
