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

Shutdown function (TSV6293, TSV6295)

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 21 and Figure 22 show the test configurations).
