Description
The TSV630 and TSV631 devices are single operational amplifiers offering low voltage, low power operation and rail-to-rail input and output. With a very low input bias current and low offset voltage (500 µV maximum for the A version), the TSV630 and TSV631 are ideal for applications that require precision. The devices can operate at power supplies ranging from 1.5 to 5.5 V, and are therefore ideal for battery-powered devices, extending battery life. These products feature an excellent speed/power consumption ratio, offering a 880 kHz gain bandwidth while consuming only 60 µA at a 5-V supply voltage. These op-amps are unity gain stable for capacitive loads up to 100 pF . The devices are internally adjusted to provide very narrow dispersion of AC and DC parameters, especially power consumption, product gain bandwidth and slew rate. The TSV630 provides a shutdown function. Both the TSV630 and TSV631 have a high tolerance to ESD, sustaining 4 kV for the human body model. Additionally, they are offered in micropackages, SC70-6 and SOT23-6 for the TSV630 and SC70-5 and SOT23-5 for the TSV631. They are guaranteed for industrial temperature ranges from -40° C to +125° C. All these features combined make the TSV630 and TSV631 ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings (AMR)
- All voltage values, except differential voltages, are with respect to network ground terminal.
- Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
- V CC-Vin must not exceed 6 V.
- Input current must be limited by a resistor in series with the inputs.
- 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 capacitor is charged to the specified voltage, then discharged directly between
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. Table 2. Operating conditions

3.8 Macromodel
An accurate macromodel of the TSV630 and TSV631 is available on STMicroelectronics’ web site at www.st.com. This model is a trade-off between accuracy and complexity (that is, time simulation) of the TSV63x operational amplifiers. It emulates the nominal performances of a typical device within the specified operating conditions mentioned in the datasheet. It also helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
