Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Decouple the power supply with a 0.1μF capacitor placed close to the Vcc pin.

2. Input Connections:

   • Keep input bias currents low by using high impedance sources or buffers.
   • Avoid exceeding the common-mode input voltage range which is from GND to Vcc - 1.5V.

3. Output Configuration:

   • The output can swing from 0.2V above ground to 0.2V below Vcc.
   • For best performance, load resistances should be greater than 2kΩ.

4. Stability and Compensation:

   • The LTC1261IS8 is internally compensated for unity gain stability.
   • External compensation may be necessary for gains less than 10 depending on the application.

5. Temperature Considerations:

   • The device operates over the industrial temperature range (-40°C to +85°C).
   • Be aware that parameters like offset voltage and bias current are sensitive to temperature variations.

6. Layout Guidelines:

   • Keep signal paths short and direct to minimize noise pickup.
   • Use ground planes to reduce noise and improve performance.

7. Handling Precautions:

   • The device is sensitive to electrostatic discharge (ESD); use appropriate ESD protection measures during handling and assembly.
