- Wide supply range 1.8V to 5.5V compatible with modern low-voltage microcontroller systems
What is OPA4330AIPW used for?
The OPA4330AIPW is well suited for precision sensor signal conditioning in portable medical devices, data acquisition front-ends, and battery-powered industrial instruments where low offset and low power consumption are critical. Its rail-to-rail capability makes it ideal for single-supply designs such as bridge amplifiers, thermocouple interfaces, and 4–20mA current loop transmitters. The quad package is commonly used in multi-channel analog front-end circuits for PLCs, weighing scales, and temperature measurement systems.

Frequently Asked Questions
What is the supply voltage range of the OPA4330AIPW?
The OPA4330AIPW operates from a single supply of 1.8V to 5.5V or a dual supply of ±0.9V to ±2.75V, making it compatible with modern 1.8V and 3.3V microcontroller systems as well as traditional 5V analog designs.
What does 'zero-drift' mean in the context of OPA4330AIPW?
Zero-drift refers to the auto-zeroing correction technique used inside the OPA4330AIPW that continuously compensates for input offset voltage and its drift over temperature. This results in a maximum input offset of 5µV and near-zero temperature drift, enabling stable precision measurements across the full industrial temperature range of −40°C to +125°C.
What package does the OPA4330AIPW use and how many amplifiers does it contain?
The OPA4330AIPW comes in a 14-pin TSSOP (PW) package and contains four independent operational amplifiers. The quad configuration saves PCB area compared to using four single op-amps and is ideal for multi-channel sensor interfaces in compact designs.
Is the OPA4330AIPW suitable for battery-powered applications?
Yes. Each amplifier in the OPA4330AIPW draws only 350µA of quiescent current, giving a total device current of approximately 1.4mA. Combined with its 1.8V minimum supply capability, it is an excellent choice for long-life battery-powered instruments, wearables, and remote sensing nodes.
What are common alternatives to the OPA4330AIPW?
Common alternatives include the OPA4333AIPW (lower power, same zero-drift family), the OPA4188IPW (higher precision, 25µV offset), and the MCP6004 from Microchip (lower cost, rail-to-rail, 1MHz GBP). Selection depends on the required offset voltage, bandwidth, and supply current budget for your application.
