Description
The TSV85x, TSV85xA series of single, dual, and quad operational amplifiers offer low voltage operation with a rail-to-rail output swing. The TSV85x, TSV85xA series outperforms the industry standard LMV321, proposing lower supply voltage capability, enhanced input offset voltage, and smaller packages. The devices are offered with either industry stan dard pinouts or with a power-saving shutdown feature that reduces the supply current to a maximum of 50 nA at 25 °C. The wide temperature range, high ESD tolerance, and au tomotive grade qualification ease the use in harsh automotive applications.

- The exposed pads of the DFN8 2x2 and QFN16 3x3 can be connected to VCC- or left floating.
2 Absolute maximum ratings and operating conditions
Table 2. Absolute maximum ratings (AMR)
- All voltage values, except differential voltage, are with respect to network ground terminal.
- The differential voltage is the non-inverting input term inal with respect to the inverting input terminal.
- VCC-Vin must not exceed 6 V, Vin must not exceed 6 V.
- Input current must be limited by a resistor in series with the inputs.
- VCC-Vshdn must not exceed 6 V, Vin must not exceed 6 V.
- Short-circuits can cause excessive heating and destructive dissipation.
- Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
- Machine model: a 200 pF cap is charged to the spec ified voltage, then discharged directly between two
combinations with other pins floating.
- Charged device model: all pins plus package ar e charged together to the specified voltage and then
discharged directly to the ground.

4 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 V CC- - 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 be low the rail when connected to a 10 kΩ 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 th e 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 operat ional 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. ΔVio
