Application information

4.1

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 VCC 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.

4.2

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 (VCC-) - 0.1 V to (VCC+) + 0.1 V. The transition between the two pairs appears

at (VCC+) - 0.7 V. In the transition region, the performance of CMRR, PSRR, Vio, and THD is

slightly degraded (as shown in Figure 13 and Figure 14 for Vio vs. Vicm).

The devices are guaranteed without phase reversal.

4.3

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.
