Description

The TSV912H and TSV912AH operational amplifiers offer low voltage operation and rail-to- rail input and output. The devices feature an excellent speed/power consumption ratio, offering an 8 MHz gain- bandwidth product while consuming only 1.1 mA maximum at 5 V. They are unity gain stable and feature an ultra-low input bias current. The TSV912H is a high temperature version of the TSV912, and can operate from -40°C to +150°C with unique characteristics. Its main target applications are automotive, but the device is also 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

  1. All voltage values, except differential voltage, are with respect to network ground terminal.
  2. Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
  3. V CC-Vin must not exceed 6 V.
  4. Input current must be limited by a resistor in series with the inputs.
  5. Short-circuits can c ause excessive heating and destructive dissipation.
  6. Human body model: a 100 pF capacit or is charged to the specified voltage, then discharged through a

while the other pins are floating.

  1. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between

connected pin combinations while the other pins are floating.

  1. Charged device model: all pins and the package are charged together to the specified voltage and then

discharged directly to the ground through only one pin. This is done for all pins. Table 2. Operating conditions
