AD847SQ

AD847SQ is an Analog Devices high-speed differential amplifier. It amplifies the difference between two inputs while rejecting common-mode signals, making it well-suited for precision instrumentation and ADC front-end applications.
Key points:
- Purpose: convert small differential signals to a single-ended output with good common-mode rejection.
- Features (typical): low offset and bias, low input-referred noise, wide bandwidth, and strong output drive for single- or dual-supply systems.
- Packaging: “SQ” denotes a specific package option; exact pinout and package vary by revision.
- Applications: sensor conditioning, instrumentation amplifiers, bridge sensors, transimpedance stages in photodiode or current-sense paths; can be used with external resistors to set gain.
Notes:
- Check the latest AD847SQ datasheet for current electrical specs (bandwidth, slew rate, input/output ranges) and pinout.
- Ensure your common-mode input range and supply rails are compatible with your signal.

AD847SQ features (concise):
- Dual operational amplifier in an 8-pin SQ package.
- High-speed performance: fast slew rate and wide bandwidth for rapid signals.
- Low noise and low distortion for precision amplification.
- Low input bias current with good input offset voltage and drift characteristics.
- Flexible power supply: supports single-supply or dual-supply operation over a wide voltage range.
- Moderate to good output drive with near-rail swing under suitable conditions.
- Suitable for instrumentation, buffering, signal conditioning, and high-speed applications.
Note: For exact electrical specs (gain bandwidth product, slew rate, noise, offset, supply ranges, etc.), please consult the AD847 datasheet.

Pin count: 8 pins (SOIC-8). Function: A single-channel operational amplifier (analog amplifier).

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: A US-based multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing (DSP) integrated circuits for diverse markets.
