Digitally Programmable Precision Voltage Divider for PGAs
General Description
The MAX5420 and MAX5421 are digitally programmable precision voltage dividers optimized for use in digitally programmable gain amplifier configurations.
The MAX5420/ MAX5421 operate from a single +5V supply or dual ±5V supply, and consume only 3µA supply current.
These devices consist of a digitally selectable resistor array that provides four precision noninverting gains of 1, 2, 4, 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 ...
