Key Features

  • 10MHz gain-bandwidth product with JFET input for ultra-low bias current (0.00002µA @ 25°C)
  • 120dB minimum common-mode rejection ratio for superior noise immunity
  • Single-supply voltage-feedback architecture with precision offset performance
  • Small Outline (MSOP-8) packaging for compact, space-saving PCB designs

Applications

The OPA141AIDGKR is ideal for precision instrumentation and sensor signal conditioning where low noise and high accuracy are critical. Its JFET input stage makes it well-suited for high-impedance transducer interfaces such as photodiode amplifiers and electrochemical sensors. It is also widely used in medical equipment, data acquisition front-ends, and audio measurement systems requiring low distortion and wide bandwidth.

Frequently Asked Questions

What is the gain-bandwidth product of the OPA141AIDGKR?

The OPA141AIDGKR has a gain-bandwidth product of 10MHz, making it suitable for precision amplification applications requiring wide signal bandwidth combined with low noise and high accuracy.

What is the input bias current of the OPA141AIDGKR?

The OPA141AIDGKR features an extremely low input bias current of 0.00002µA (20pA) at 25°C, with a maximum of 0.005µA. This makes it ideal for high-impedance source applications such as photodiode and electrochemical sensor interfaces.

What package does the OPA141AIDGKR come in?

The OPA141AIDGKR is available in a MSOP-8 small outline package (DGK suffix), which offers a compact footprint suitable for space-constrained PCB designs in portable and precision instruments.

What are typical applications for the OPA141AIDGKR?

Typical applications include precision instrumentation amplifiers, sensor signal conditioning, photodiode transimpedance amplifiers, medical diagnostics equipment, data acquisition systems, and audio measurement circuits where low noise and high common-mode rejection (120dB min) are required.

Is the OPA141AIDGKR a drop-in replacement for other JFET op-amps?

The OPA141AIDGKR is pin-compatible with industry-standard single op-amp footprints and can replace many JFET input op-amps such as the OPA627 in space-constrained designs, offering improved CMRR of 120dB minimum and lower bias current in a smaller MSOP-8 package.
