OP27GZ

OP27GZ is a variant of Analog Devices’ OP27 family: a precision, low-noise operational amplifier aimed at instrumentation and precision analog signaling. Key points:
- Features low input offset and drift, low voltage noise, and high open-loop gain for accurate amplification.
- Moderate bandwidth (not rail-to-rail) suitable for instrumentation, active filters, ADC front-ends, and servo/feedback loops.
- GZ suffix indicates a specific package variant (commonly 8-pin DIP or SO-8) and RoHS-compliant packaging.
- Typical operation uses dual supplies (roughly ±3 V to ±18 V; single-supply operation is possible with proper biasing and headroom).
- Not a rail-to-rail device; ensure input common-mode and output swing stay within limits for your circuit.
- Always consult the datasheet for exact pinout, electrical specs, and packaging details.
If you need exact numbers (offset, GBW, slew rate, etc.), I can pull the latest figures from the datasheet.

OP27GZ is a high‑precision, low‑noise op‑amp (bipolar input) in an 8‑pin package (GZ Pb‑free variant). Key features:
- Very low input offset voltage: typical ~75 µV; max ~200 µV
- Low input bias current: tens of nA
- Low voltage noise: around 0.9 nV/√Hz
- Gain bandwidth product ≈ 8 MHz
- Slew rate ≈ 0.6–0.8 V/µs
- Wide supply range: ±3 V to ±18 V (total 6–36 V)
- Good common‑mode rejection and power supply rejection
- Stable with capacitive loads; good temperature drift characteristics
- Output can swing close to rails with suitable load
- Commonly available in 8‑pin packages; Pb‑free variant (GZ)
Applications: precision signal conditioning, instrumentation amplifiers, active filters, audio preamps.

- Pin count: 8 (DIP-8/SO-8 package)
