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).
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
output is in a high impedance state. The SHDN pin must never be left floating but tied to
