Instructions for Use:
- Supply Voltage: Ensure the supply voltage is within the specified range (2.7V to 5.5V). The device may not operate correctly outside this range.
- Quiescent Current: The typical quiescent current is 60μA. Keep this in mind for power budget considerations, especially in battery-powered applications.
- Output Voltage Range: The output can swing from 0V to VCC-1.4V under no load conditions. Design your circuit considering these limits.
- Input Offset Voltage: This parameter affects accuracy. Ensure that any error due to offset voltage is within acceptable limits for your application.
- Common Mode Rejection Ratio (CMRR): High CMRR ensures that common-mode signals are effectively rejected, which is crucial for differential measurements.
- Power Supply Rejection Ratio (PSRR): High PSRR means the device is less sensitive to power supply fluctuations, improving stability.
- Bandwidth: For applications requiring fast response, ensure that the signal frequency does not exceed the small signal bandwidth.
- Slew Rate: Important for large signal swings; the maximum slew rate is 0.5V/μs.
- Output Current Limitation: The device can provide up to 20mA before going into current limiting. Avoid exceeding this limit to prevent damage.
