The BA2904YF-MGE2 is a two-channel operational amplifier (Op-Amp) manufactured by ROHM. It is a ground sensing device, which means it senses and amplifies small fluctuations in the ground voltage. It has a wide operating voltage range of 3-32V, and is housed in an 8-pin SOP package for convenient surface mounting. The amplifier features high open loop gain, high voltage transients, low input bias current, and low offset voltage. It can be used in a variety of low power, low voltage applications such as audio, signal processing, and instrumentation.
