4 Application information
4.1 Operating voltages
The TSV630 and TSV631 can operate from 1.5 V to 5.5 V. Their parameters are fully
specified for 1.8-V, 3.3-V, and 5-V power supplies. However, the parameters are very stable
in the full V
CC
range and several characterization curves show the TSV63x characteristics
at 1.5
V. Additionally, the main specifications are guaranteed in extended temperature
ranges from -40°
C to +125° C.
4.2 Rail-to-rail input
The TSV630 and TSV631 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 17 and Figure 18 for V
io
vs. V
icm
).
The device is guaranteed without phase reversal.
4.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: to a maximum of 35 mV
above and below the rail when a 10
kΩ resistive load is connected to V
CC
/2.
