3 Application information
3.1 Operating voltages
The TSV6390 and TSV6391 can operate from 1.5 to 5.5 V. Their parameters are fully
specified for 1.8, 3.3 and 5 V power supplies. However, the parameters are very stable in the
full V
CC
range and several characterization curves show the TSV639x characteristics at
1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges
from -40° C to +125° C.
3.2 Rail-to-rail input
The TSV6390 and TSV6391 are built with two complementary PMOS and NMOS input
differential pairs. The devices have a rail-to-rail input, and the input common mode range is
extended from V
CC-
-0.1 V to V
CC+
+0.1 V. The transition between the two pairs appears at
V
CC+
-0.7 V. In the transition region, the performance of CMRR, PSRR, V
io
and THD is
slightly degraded (as shown in Figure 13 and Figure 14 for V
io
vs. V
icm
).
The devices are guaranteed without phase reversal.
3.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to V
CC
/2.
3.4 Shutdown function (TSV6390)
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’s
output is in a high impedance state. The SHDN
pin must never be left floating, but tied to
V
CC+
or V
CC-
.
