3 Application information
3.1 Operating voltages
The TSV620 and TSV621 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 TSV62x 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 TSV62x is built with two complementary PMOS and NMOS input differential pairs. The
device has 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 performances of CMRR, PSRR, V
io
and THD are slightly degraded
(as shown in Figure 14 and Figure 15 for V
io
vs. V
icm
).
The device is guaranteed without phase reversal.
3.3 Rail-to-rail output
The operational amplifier’s output level 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.
