The HA1630D04/05/06 are high slew rate dual CMOS Operational Amplifiers realizing low voltage operation, low  input offset voltage and low supply current. In addition to a low operating voltage from 1.8V, these device output can  achieve full swing output voltage capability extending to either supply. Available in an ultra-small TSSOP-8 and  MMPAK-8 package that occupy more small area against the SOP-8.
