The RL78 family of devices offer a series of devices having different types of amplifier. There are PGA and Amplifier Unit that contains three OPAs and 1 PGA in RL78. The MSPM0 OPA modules are completely flexible, and can individually, or in combination, replace many discrete amplifiers in sensing or control applications. The differences between MSPM0 OPA modules and RL78 Amplifier Unit are included in Table 5-5.
