Instructions for Use:
- Supply Voltage: The OP291GSZ operates with a supply voltage range from 2.7V to 6.0V. Ensure that the power supply is stable and within this range to avoid damage or erratic behavior.
- Quiescent Current: Each amplifier in the dual package consumes approximately 45μA at 5V. This low quiescent current makes it suitable for battery-powered applications.
- Input Offset Voltage: The input offset voltage is typically 25μV at room temperature. This low offset voltage is crucial for precision applications.
- Input Bias Current: The input bias current is extremely low at 2pA, making the OP291GSZ ideal for high-impedance circuits.
- Noise Performance: With a noise density of 3nV/√Hz and 0.1pA/√Hz, the OP291GSZ is suitable for low-noise applications.
- Common-Mode Rejection Ratio (CMRR): The CMRR is 120dB, ensuring that common-mode signals are effectively rejected.
- Power-Supply Rejection Ratio (PSRR): The PSRR is also 120dB, indicating excellent rejection of power supply variations.
- Slew Rate: The slew rate is 0.3V/μs, which is suitable for most general-purpose applications.
- Gain Bandwidth Product (GBW): The GBW is 1.2MHz, providing a good balance between gain and bandwidth.
