Detailed Description

Dual zero-drift CMOS operational amplifier in 8‑SOIC for high-temperature use. Rail-to-rail output, very low drift, low bias current, and micropower operation. Wide supply range 1.8–5.5 V. Designed for precision sensing and DC accuracy over -55°C to 175°C. In-stock quantity: 2060 units (availability may vary).

Key Features

Dual op amp (2 channels) with zero-drift architecture

Rail-to-rail output for maximum dynamic range

Wide supply voltage: 1.8 V to 5.5 V

Gain-bandwidth product: 350 kHz (typical)

Slew rate: about 0.16 V/µs (typical)

Very low input bias current: about 70 pA (typical)

Low quiescent supply current: about 17 µA per channel (typical, micropower)

Output drive: up to ~5 mA per channel

Operating temperature: -55°C to 175°C (high-temperature grade)

CMOS input stage for low power and high precision

RoHS3 compliant

Surface-mount 8‑SOIC package for compact designs

Key Advantages

Precision you can trust: near-zero offset and ultra-low drift keep measurements stable over time and temperature

Wide temperature range: dependable operation up to 175°C for harsh environments

Battery-friendly: micropower consumption extends battery life in portable devices

Full output swing: rail-to-rail output maximizes resolution with low-voltage supplies

Easy to design-in: standard dual op-amp pinout, broad supply range, and stable performance

Clean low-frequency behavior: zero-drift topology minimizes 1/f noise and offset errors for DC and low-frequency sensing
