The ROHM BU7242FVM-TR is a dual CMOS operational amplifier in an 8-MSOP surface-mount package.
Input offset voltage is 1 mV typical, which is adequate for 8- to 10-bit accuracy paths but worth budgeting for if you're targeting 12-bit or better.
The 8-MSOP package (2.80 mm body width) keeps board area tight for two-channel designs.
The BU7244F- and BU7244FV- are quad-channel versions of the same core amplifier.
The output is rail-to-rail, but the input common-mode range is not — it stops 1.1 V below the positive rail in typical CMOS designs, so high-side sensing at 3.3 V single supply requires checking the input voltage range against the datasheet.
Input bias current is 1 pA typical, and output current per channel is 12 mA.
