The LM747 is a general purpose dual operational amplifier. The two amplifiers share a common bias network and power supply leads. Otherwise, their operation is completely independent. Additional features of the LM747 are: no latch-up when input common mode range is exceeded, freedom from oscillations, and package flexibility.
No frequency compensation required
Wide common-mode and differential voltage ranges
Low power consumption
Balanced offset null
14 pin DIP. Actual brand may vary from picture.
