OPA333AIDBVR

Texas Instruments OPA333AIDBVR - Ultra-Precision Zero-Drift Operational Amplifier

The OPA333AIDBVR from Texas Instruments is a high-precision, zero-drift operational amplifier designed for demanding instrumentation and measurement applications. Featuring an ultra-low input offset voltage of just 2µV and extremely low input bias current of 70pA, this op-amp delivers exceptional accuracy and stability over temperature. With rail-to-rail output capability and ultra-low power consumption of only 17µA, it's ideal for battery-powered precision instruments.

Key Features:

• Zero-Drift Architecture: Eliminates offset voltage drift over time and temperature
• Ultra-Low Offset Voltage: 2µV maximum input offset for exceptional precision
• Ultra-Low Input Bias Current: 70pA typical for minimal signal loading
• Rail-to-Rail Output: Maximizes dynamic range in low-voltage applications
• Ultra-Low Power Consumption: 17µA supply current for extended battery life
• Wide Supply Voltage Range: 1.8V to 5.5V operation
• Extended Temperature Range: -40°C to 125°C for industrial applications
• Compact Package: SOT-23-5 surface mount package saves board space

Applications:

The OPA333AIDBVR is perfectly suited for precision instrumentation applications including:

• Medical instrumentation and patient monitoring equipment
• Industrial process control and sensor signal conditioning
• Portable test and measurement instruments
• High-precision data acquisition systems
• Thermocouple and RTD temperature measurement
• Strain gauge and bridge amplifiers
• Battery-powered precision instruments
• Weigh scales and load cell amplifiers

Performance Advantages:

The zero-drift architecture of the OPA333AIDBVR eliminates the long-term offset voltage drift commonly found in traditional operational amplifiers, ensuring stable and accurate measurements over the entire operating temperature range. Combined with its ultra-low power consumption, this makes it an excellent choice for portable and battery-operated precision instruments where both accuracy and battery life are critical.
