TSV6290, TSV6290A, TSV6291, TSV6291A Application information
5 Application information
5.1 Operating voltages
The TSV6290 and TSV6291 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 TSV629x characteristics at
1.5 V. Additionally, the main specifications are guaranteed in extended temperature ranges from -40 °C to 125 °C.
5.2 Rail-to-rail input
The TSV6290 and TSV6291 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 CMR, SVR, V io
and THD is
slightly degraded (as shown in Figure 18 and Figure 19 for V
io
vs. V icm
).

5.3
The devices are guaranteed without phase reversal.
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.
