Description and Introduction

1.8V, 17?A, microPower, Precision, Zero-Drift CMOS Op Amp 8-SOIC -40 to 125 The **OPA333AIDG4** is a precision, low-power operational amplifier (op-amp) designed for applications requiring high accuracy and minimal power consumption. Manufactured by Texas Instruments, this device features an ultra-low offset voltage (as low as 10 µV) and near-zero drift over time and temperature, making it ideal for precision signal conditioning in battery-powered and portable systems.  

Operating on a supply voltage range of 1.8V to 5.5V, the OPA333AIDG4 consumes just 17 µA of quiescent current, extending battery life in energy-sensitive designs. Its rail-to-rail input and output capabilities ensure maximum dynamic range, even at low voltages. Additionally, the op-amp offers excellent noise performance and high common-mode rejection ratio (CMRR), enhancing signal integrity in noisy environments.  

Housed in an 8-pin SOIC package, the OPA333AIDG4 is well-suited for applications such as sensor amplification, medical instrumentation, and portable test equipment. Its robust performance, combined with low power consumption, makes it a reliable choice for designers seeking precision in constrained power budgets.  

With its combination of accuracy, efficiency, and versatility, the OPA333AIDG4 stands out as a high-performance solution for demanding analog circuits.

Application Scenarios & Design Considerations

1.8V, 17?A, microPower, Precision, Zero-Drift CMOS Op Amp 8-SOIC -40 to 125

Alternative Part Number

  • OPA333AIDBVR --: Same OPA333 zero-drift amplifier family in a smaller SOT-23-5 package, electrically equivalent and widely available.
  • AD8628ARZ --: Pin-compatible zero-drift, low-offset op-amp with comparable supply range and performance, suitable as a direct functional replacement.
  • MAX4238ASA+ --: Low-noise, low-offset precision op-amp with similar supply voltage and bandwidth, usable as an alternative in most OPA333 applications.

Description and Introduction

1.8V, 17?A, microPower, Precision, Zero-Drift CMOS Op Amp 8-SOIC -40 to 125 The **OPA333AIDG4** is a precision, low-power operational amplifier (op-amp) designed for applications requiring high accuracy and minimal power consumption. Manufactured by Texas Instruments, this device features an ultra-low offset voltage (2 µV max) and near-zero drift over time and temperature, making it ideal for precision signal conditioning in battery-powered and portable systems.  

Operating on a supply voltage range of **1.8V to 5.5V**, the OPA333AIDG4 consumes only **17 µA of quiescent current**, ensuring extended battery life in energy-sensitive designs. Its rail-to-rail input and output capabilities enhance dynamic range, while the absence of 1/f noise ensures stable performance in DC-sensitive applications such as sensor interfaces, medical instrumentation, and data acquisition systems.  

Housed in an **8-pin SOIC (DG4) package**, the OPA333AIDG4 offers excellent thermal and long-term stability. Its robust design includes EMI filtering to minimize interference in noisy environments. Engineers favor this op-amp for its combination of precision, low power, and compact footprint, making it a reliable choice for high-performance analog circuits.  

With its exceptional specifications and versatility, the OPA333AIDG4 is well-suited for industrial, automotive, and consumer electronics where accuracy and efficiency are critical.

Alternative Part Number

  • OPA333AIDBVR --: Same OPA333 zero-drift amplifier family in SOT-23-5 package; identical electrical performance, suitable drop-in for space-constrained designs.
  • AD8628ARZ --: Low-offset, low-drift chopper-stabilized op-amp with comparable 5V single-supply operation and similar offset voltage, a strong cross-manufacturer alternative.
  • MAX4238ASA+ --: Ultra-low offset/drift CMOS op-amp with rail-to-rail output and similar supply range, usable as a functional replacement where OPA333 availability is limited.
