application information tsx63x, tsx63xa 18/31 docid024293 rev 1 4 application information 4.1 operating voltages the amplifiers of the tsx63x and tsx63xa series can operate from 3.3 to 16 v. their parameters are fully specified at 3.3, 5, 10 and 16 v power supplies. however, the parameters are very stable in the full v cc range. additionally, the main specifications are guaranteed in extended temperature ranges from -40 c to +125 c. 4.2 rail-to-rail input the tsx63x and tsx63xa 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. however, the performance of these devices is clearly optimized for the pmos differential pairs (which means from v cc- - 0.1v to v cc+ - 1.65v). beyond v cc+ - 1.65 v, the op-amp is still functional but with a degraded performance as can be observed in the electrical characterist ics section of this datasheet (mainly v io ). these performances are suitable for a number of applications requiri ng rail-to-rail input and output. the devices are guaranteed without phase reversal. 4.3 input offset voltage drift over temperature the maximum input voltage drift over the temperature variation is defined as the offset variation related to offset value measured at 25 c. the operational amplifier is one of the main circuits of the signal conditioning chai n, and the amplifier input offset is a major contributor to the chain accuracy. the signal chain accuracy at 25 c can be compensated during production at application level. the ma ximum input voltage drift over temperature enables the system designer to anticipate the effect of temperature variations. the maximum input voltage drift over temperature is computed using equation 1 . equation 1 with t = -40 c and 125 c. the datasheet maximum value is guaranteed by a measurement on a representative sample size ensuring a c pk (process capability in dex) greater than 2. v io t ----------- - max v io t () v io 25 c () ? t25 c ? --------------------------------------------------- =
