General Description
BL370X series operates from a single 2.1V to 5.5V supply or dual ±1.05V to ±2.75V supplies ,The BL370X have a high gain-
bandwidth product of 12MHz, a slew rate of 11V/μs, and a quiescent current of 1.1mA per amplifier at 5V. The BL370X are
designed to provide optimal performance in low voltage and low noise systems. The input common mode voltage range includes
ground, They are specified over the extended industrial temperature range (-40℃ to +125℃). The operating range is from 2.1V
to 5.5V. The BL3701 single is available in Green SC70-5 and SOT23-5 packages. The BL3702 dual is available in Green SOP-
8 and MSOP-8 packages. The BL3704 Quad is available in Green SOP-14 and TSSOP-14 packages.
