Application Information

HM8651 series op amps are fabricated on a state-of-the-art 0.6micron CMOS process. They are unity-gain

stable and suit-able for a wide range of general-purpose applications. Rail-to-rail input/output make them

ideal for driving sampling A/D converters. They are also well suited for controlling the output power in cell

phones. These applications often require high speed and low noise. In addition, the HM8651 series offers a

low cost solution for general-purpose and consumer video/audio applications.

Rail-to-rail input and output swing significantly increases dynamic range, especially in low voltage supply

applications. The following diagram show a real waveform under the condition-HM8651 in unity-gain

5Vp-p sinusoid. Output voltage swing is approximately 4.95Vp-p. Power supply pins should be bypassed

with 0.0F ceramic capacitors.
