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

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

±

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.
