Precision quad op-amp for signal conditioning
The MAX44243ASD+T is a quad general-purpose operational amplifier from Analog Devices, packaged in a 14-SOIC (0.154", 3.90mm width) surface-mount package.
Offset voltage and input bias — the dc precision story
With a typical input offset voltage of just 1 µV and input bias current of 300 pA, this op-amp handles microvolt-level signals without the need for external nulling. The 40 mA output current per channel drives moderate loads like ADC inputs or analog multiplexers directly.
Temperature grade and supply current budget
The total quiescent supply current is 420 µA across all four amplifiers — 105 µA per channel — keeping the thermal rise low in the 14-SOIC package.
Analog Devices lists the MAX44243ASD+T as Active in production, with ROHS3 compliance.
