Zero-Drift Op Amp AD8551ARZ-REEL7, Precision Chopper-Stabilized Amplifier
The AD8551ARZ-REEL7 is a high-precision, zero-drift operational amplifier from Analog Devices, designed for applications requiring ultra-low offset voltage and minimal drift over time and temperature. Utilizing auto-zero (chopper-stabilized) technology, it achieves an exceptionally low input offset voltage of 1 µV and near-zero drift (0.005 µV/°C), making it ideal for precision DC amplification in sensor interfaces, medical instrumentation, and industrial control systems. The device operates from a single supply voltage (2.7V to 5.5V) with rail-to-rail input/output (RRIO) capability, ensuring maximum dynamic range in low-voltage designs. Packaged in an 8-pin SOIC with tape-and-reel (TR) delivery, it is optimized for automated assembly in space-constrained applications.
Applications
The AD8551ARZ-REEL7 is widely used in precision analog circuits, including:
● Sensor Signal Conditioning: Strain gauges, thermocouples, and bridge amplifiers benefit from its low drift.
● Medical Instrumentation: ECG amplifiers, blood glucose monitors, and portable diagnostic equipment.
● Industrial Automation: PLCs, motor control feedback loops, and precision current sensing.
● Data Acquisition Systems: High-accuracy ADC/DAC buffer amplifiers.
● Automotive Electronics: Engine control units (ECUs) and safety-critical sensor interfaces.
Alternative Models
1. AD8551ARZ: Identical specs but in tube packaging instead of tape-and-reel.
2. OPA350UA (TI): Higher bandwidth (6.5 MHz) and slew rate (5 V/µs) but lower CMRR (80 dB).
3. OPA364AID (TI): 7 MHz GBP, lower power (1.1 mA), but higher offset drift (3 µV/K).
4. AD8571ARZ: Similar zero-drift performance but with different noise characteristics.
