Application information

4.1

Operating voltages

The TSV85x, TSV85xA can operate from 2.3 to 5.5 V. The devices’ parameters are fully

specified for 2.7 V and 5 V power supplies. Additionally, the main specifications are

guaranteed in extended temperature ranges from -40 °C to +125 °C.

4.2

Input common-mode range

The TSV85x, TSV85xA has an input common-mode range that includes ground. The input

common-mode range is extended from VCC- - 0.2 V to VCC+ - 1 V, with no output phase

reversal.

4.3

Rail-to-rail output

The operational amplifiers’ output levels can go close to the rails: 180 mV maximum above

and below the rail when connected to a 10 k

Ω resistive load to VCC/2.

4.4

Input offset voltage drift over temperature

The maximum input voltage drift over the temperature variation is defined as follows.

for Tmin < T < Tmax.

4.5

PCB layouts

For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible

to the power supply pins.

4.6

Macromodel

Accurate macromodels of the TSV85x, TSV85xA are available on STMicroelectronics’ web

site at www.st.com. These models are a trade-off between accuracy and complexity (that is,

time simulation) of the TSV85x, TSV85xA operational amplifiers. They emulate the nominal

performances of a typical device within the specified operating conditions mentioned in the

datasheet. They also help to validate a design approach and to select the right operational

amplifier, but they do not replace on-board measurements.
