NOTES: (1) An asterisk (*) specifies the same value as the grade to the left. (2) Frequency response can be strongly influenced by PC board parasitics. The OPA651
is nominally compensated assuming 2pF parasitic load. The demonstration boards show low parasitic layouts for the different package styles.
