OPERATIONAL AMPLIFIERS DESCRIPTION
Each driver has two output stages scaled in cur-
rent by a factor K = 10.
In voltage mode configuration the two outputs are
shorted.
In charge mode configuration OUT1 drives a ca-
pacitor Cint and is closed in feedback, while
OUTK drives the piezo, mirroring the current sup-
plied to Cint, with a current multiplied by a K fac-
tor (see Fig.2).
The supply voltage can be internally generated
by the DC-DC converter, or external, maintaining
the DC-DC converter in sleep mode (PIN3
shorted to ground), in this case the supply volt-
age can be 0 to V5/12+4 minimum value up to
70V in single supply or V5/12+4 to 35V symmetri-
cal to ground.
The drivers have 130dB DC gain and the Band-
width is 500KHz. Stability is guaranteed with a
minimum gain of 20dB, for a capacitive load in
the range 0.4nF up to 24nF.
