4.4 Optimization of DC and AC parameters
These devices use an innovative approach to reduce the spread of the main DC and AC
parameters. An internal adjustment achieves a very narrow spread of current consumption
(29
µA typical, min/max at ±17%). Parameters linked to the current consumption value,
such as GBP, SR and AVd benefit from this narrow dispersion. All parts present a similar
speed and the same behavior in terms of stability. In addition, the minimum values of GBP
and SR are guaranteed (GBP = 350
kHz min, SR = 0.12 V/µs min).
4.5 Shutdown function (TSV623, TSV625)
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the
SHDN must be pulled down to V
CC-
. When in shutdown mode, the amplifier
output is in a high impedance state. The
SHDN pin must never be left floating but tied to
V
CC+
or V
CC-
. The turn-on and turn-off times are calculated for an output variation of
±200 mV (Figure 18 and Figure 19 show the test configurations). Figure 20 and Figure 21
show output voltage behavior when the SHDN pin is toggled.
