Product details

Active dual CMOS op-amp for low-power signal chains

The ROHM BU7242SNUX-TR is a dual CMOS operational amplifier with rail-to-rail output, designed for battery-powered and space-constrained analog front-ends. The CMOS input stage draws only 1 pA input bias current, preserving signal integrity from high-impedance sources like photodiodes or pH probes.

The 8-UFDFN exposed-pad package (VSON008X2030, 2 mm × 3 mm body) keeps board area small; the exposed pad needs a thermal via to the ground plane for rated output current of 12 mA per channel. Active lifecycle status means no near-term end-of-life risk for production builds.

Frequently asked questions

Is BU7242SNUX-TR rail-to-rail?

Yes, the output type is rail-to-rail, allowing the output to swing within millivolts of both supply rails.

What is the GBW of BU7242SNUX-TR?

The gain bandwidth product is 900 kHz, suitable for audio-band and low-frequency sensor signal chains.

Can BU7242SNUX-TR replace BU7242 or similar dual op-amps?

The BU7242FVM-TR is a functional peer with the same 900 kHz GBW, 0.4 V/µs slew rate, and 1 pA input bias, but in an MSOP-8 package. The BU7242SNUX-TR's VSON008X2030 footprint is smaller and includes an exposed thermal pad — verify PCB pad layout before substituting.
