Efficiently Power that Op Amp

July 24, 2014 9:43 am | by Chris Glazer, Texas Instruments, www.ti.com | Texas Instruments | Blogs | Comments

In many applications, such as temperature sensing, two supply voltages are needed to power an op amp in the system—one positive and one negative. This dual supply is needed by the amplifier in order to properly measure signals very close to or even below ground. If the negative supply input of the op amp was just grounded and a single, positive supply voltage used, these signals would not be processed properly.
