The SE5230DR2 is a low voltage operational amplifier designed to operate with supply voltages ranging from 1.8 V to 15 V, accommodating both single and dual supply configurations. It features a bias adjusting pin that allows for control over supply current and power consumption, achieving a low current draw of 110 ¬µA at ¬±0.9 V supply when the bias pin is left open. The device offers a typical unity gain bandwidth of 250 kHz, which can be increased to 600 kHz with higher supply current settings. This operational amplifier has a unique input stage that extends the common-mode input range beyond the supply rails by 250 mV, making it suitable for a variety of low voltage applications. It exhibits a low input bias current of ¬±40 nA and a high open-loop gain of 125 dB, which enhances accuracy in signal processing, particularly in transducer applications. The output stage is class AB, capable of swinging to within 100 mV of the supply voltages, providing a large dynamic range. The SE5230DR2 is particularly well-suited for portable audio equipment, remote transducer amplifiers, and precision instruments due to its low power consumption and noise specification of 30 nV/,àöHz. It is also internally compensated, reducing the need for external components. The device is available in a Pb-free SOIC-8 package.
