Description
The TSV91x and TSV91xA operational amplifiers (op amps) offer low voltage operation and rail-to-rail input and output, as well as an excellent speed/power consumption ratio, providing an 8 MHz gain-bandwidth product while consuming only 1.1 mA maximum at 5 V. The op amps are unity gain stable and feature an ultra-low input bias current. The devices are ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

2 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings (AMR)
- All voltage values, except the differential voltage, are with respect to network ground terminal.
- Differential voltages are the non-inverting input terminal with respect to the inverting input terminal
- VCC - 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 kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
- Machine model: 200 pF charged to the specified voltage, then discharged directly between two pins of the device with no
- Charged device model: all pins plus packages are charged together to the specified voltage and then discharged directly to

5 Application information
5.1 Driving resistive and capacitive loads
These products are low-voltage, low-power operational amplifiers optimized to drive rather large resistive loads above 2 kΩ. In a follower configuration, these operational amplifiers can drive capacitive loads up to 100 pF with no oscillations. When driving larger capacitive loads, adding a small in-series resistor at the output can improve the stability of the device (figure below shows the recommended in-series resistor values). Once the in-series resistor value has been selected, the stability of the circuit should be tested on bench and simulated with the simulation model. Figure 19. In-series resistor vs. capacitive load
