LM433

 Input offset voltage .........................................0.6mV
 Input offset current ............................................1nA
 Input bias current ...............................................3nA
Common-mode input voltage range .......0V to VS−1V
Power supply current ......................................150µA

The LM433 integrates two operational amplifiers and one 2.5V reference. The reference is based on the LMV431 adjustable shunt regulator with the output voltage adjusted to a fixed 2.5V. The Op Amps are similar to the LM358 with a common-mode input range that includes ground. Integrating the reference and Op Amps creates a solution for low cost charging applications.
