OPA333AIDBVTG4

OPA333AIDBVTG4 Description

The OPA333AIDBVTG4 from Texas Instruments is a precision, zero-drift operational amplifier (op-amp) designed for high-accuracy applications. Packaged in a compact SOT23-5 surface-mount form factor and supplied in Tape & Reel (TR), this single-channel op-amp features ultra-low input offset voltage (2 µV) and near-zero drift over time and temperature, making it ideal for precision signal conditioning. With a 1.8V to 5.5V supply range and ultra-low 17µA supply current, it excels in battery-powered and low-power systems. Its 350 kHz gain bandwidth product (GBW) and 0.16V/µs slew rate ensure stable performance in DC and low-frequency applications.

OPA333AIDBTVG4 Features

• Zero-Drift Architecture: Eliminates 1/f noise and minimizes offset voltage drift, critical for precision DC applications.
• Ultra-Low Power: 17µA quiescent current extends battery life in portable devices.
• Wide Supply Range: Operates from 1.8V to 5.5V, compatible with Li-ion, alkaline, and single-cell battery systems.
• Low Input Bias Current: 70 pA reduces errors in high-impedance sensor interfaces.
• High Output Drive: 5 mA output current supports moderate loads without external buffering.
• Robust Packaging: SOT23-5 with MSL1 (Unlimited) moisture sensitivity ensures reliability in harsh environments.
• Compliance: ROHS3 and REACH Unaffected, meeting global environmental standards.

OPA333AIDBTVG4 Applications

• Sensor Signal Conditioning: Ideal for bridge amplifiers (strain gauges, RTDs) due to low offset and drift.
• Battery-Powered Systems: Energy-efficient operation suits medical devices (glucose meters, wearables) and IoT sensors.
• Precision Instrumentation: High accuracy in data acquisition, ADC drivers, and reference buffers.
• Industrial Control: Reliable performance in process control, pressure monitoring, and low-frequency filtering.
• Portable Consumer Electronics: Enables long runtime in handheld meters, scales, and environmental sensors.
