MAX5420 Summary of contents
Page 1
... These devices consist of a digitally selectable resistor array that provides four precision noninverting gains and 8 for PGAs. The MAX5420 and MAX5421 achieve a resistor ratio accuracy of 0.025% (MAX542_A), 0.09% (MAX542_B), and 0.5% (MAX542_C). The MAX5421 includes an on-chip matching resistor for op amp bias-current compensation ...

... PGA applications. The typical application circuit of Figure 3 uses the MAX5421 with matching resistor to compensate for voltage offset due to op amp input bias currents. Use the MAX5420 with an ultra-low input bias current op amp such as the MAX4237 (Figure 4). Power Supplies and Bypassing The MAX5420/MAX5421 operate from dual ± ...
