AD549SH/883B Typical application Circuitry

AD549SH 883B

The AD549SH/883B is an ultra-low input bias current operational amplifier (op-amp) with high precision and stability. It is designed for applications that require very low input currents, such as electrometer amplifiers, photodiode amplifiers, and high-impedance buffering in sensitive measurement equipment.

Applications

This op-amp is suited for:

- Electrometer Amplifiers: In applications requiring the measurement of extremely small currents.

- Photodiode Amplifiers: For accurate conversion of light into electrical signals in optical systems.

- High-Impedance Buffering: In measurement equipment where minimal loading of the signal source is crucial.

Key Specifications

- Input Bias Current: Exceptionally low, typically in the femtoampere range, minimizing errors in high-impedance applications.

- Offset Voltage: Low, typically around 1 mV, ensuring accuracy in signal amplification.

- Supply Voltage Range: Operable within ±5 V to ±15 V, providing versatility in various circuit designs.

- Package: Enclosed in a hermetic TO-99 package, offering robustness and reliability.

Circuit Design Example: Electrometer Amplifier

To construct an electrometer amplifier using the AD549SH/883B, follow these detailed instructions:

1. Power Supply Connections

- Connect the positive supply voltage (+V) to pin 7 of the AD549SH/883B.

- Connect the negative supply voltage (-V) to pin 4.

- Ground the circuit common to pin 3.

2. Input Stage

- Connect the high-impedance source to the non-inverting input (pin 3) of the AD549SH/883B.

3. Feedback Network

- Place a high-value feedback resistor (Rf) between the output (pin 6) and the inverting input (pin 2) to set the gain.

- Optionally, add a feedback capacitor (Cf) in parallel with Rf to tailor the frequency response.

4. Output Configuration

- Connect the output (pin 6) to the next stage or to the measurement equipment.

5. System Setup

- Choose Rf and Cf based on the desired gain and bandwidth.

- Verify that the supplied voltages fall within the AD549SH/883B's operating voltage range.

Design Considerations

- Stability: Design the feedback network to ensure stability across the desired frequency range.

- Power Supply: Use a stable and low-noise power supply to minimize offset and drift errors.

- PCB Layout: Implement careful PCB layout techniques to reduce parasitic capacitance and leakage paths, especially near the high-impedance input.

- Temperature Effects: Take into account component temperature coefficients as changes in temperature can affect the amplifier's accuracy.

By adhering to these guidelines, the AD549SH/883B can be effectively utilized in an electrometer amplifier circuit, providing accurate and stable signal amplification with minimal input bias current.
