3 Application information
3.1 Operating voltages
The TSV61x 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 TSV61x characteristics at 1.5 V. Additionally, the
main specifications are guaranteed in extended temperature ranges from -40° C to +85° C.
3.2 Rail-to-rail input
The TSV61x 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.
3.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: less than 35 mV above
GND rail and less than 35 mV below V
CC
rail when connected to 10 kΩ load to V
CC
/2.
3.4 Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 10 kΩ. For lower resistive loads, the THD level may significantly
increase.
