Description

The TSZ182H is a dual operational amplifier, featuring very low offset voltages with virtually zero-drift versus temperature changes. The TSZ182H offers rail-to-rail input and output, excellent speed/power consumption ratio, and 3 MHz gain bandwidth product, while consuming just 1 mA at 5 V. The device operates over an extended range of -40 to +150°C and features an ultra-low input bias current. These features make the TSZ182H ideal for high-accuracy high-bandwidth sensor interfaces for automotive environment. Product status link TSZ182H

2 Absolute maximum ratings and operation conditions

Table 2. Absolute maximum ratings

  1. All voltage values, except differential voltage, are with respect to network ground terminal.
  2. The differential voltage is the non-inverting input terminal with respect to the inverting input terminal.
  3. V CC - Vin must not exceed 6 V, Vin must not exceed 6 V.
  4. Input current must be limited by a resistor in series with the inputs.
  5. Short-circuits can cause excessive heating and destructive dissipation.
  6. 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.
