What are the key features of ADA4627-1BRZ-RL?
- 5 fA typical input bias current from JFET input stage, enabling extremely high source-impedance signal conditioning without loading error
- 116 dB typical CMRR with 98 dB minimum for exceptional noise rejection in differential measurement circuits
- 30 V supply rail capability in a compact 8-pin SOIC for high-voltage precision analog front-end designs
What is ADA4627-1BRZ-RL used for?
The ADA4627-1BRZ-RL is designed for precision instrumentation and data acquisition front-ends where source impedances exceed 1 MΩ and input bias current must remain below 10 fA to avoid signal offset. It suits photodiode transimpedance amplifiers in optical sensing and spectrometry, where its low noise and high bandwidth enable accurate current-to-voltage conversion at low light levels. It is also used in high-impedance pH and electrochemical sensor interfaces where even picoampere leakage currents would corrupt the measurement.

Frequently Asked Questions
How low is the input bias current of ADA4627-1BRZ-RL and what does that enable in sensor interface designs?
The ADA4627-1BRZ-RL has a maximum input bias current of 2 pA average and a typical value of just 5 fA at 25°C. This extremely low current allows it to interface with sensors whose source impedance exceeds 100 MΩ, such as pH electrodes or ion-selective sensors, without introducing a measurable offset voltage that would corrupt a microvolt-level signal.
What common-mode rejection ratio does ADA4627-1BRZ-RL achieve and why does it matter for differential measurements?
The ADA4627-1BRZ-RL achieves a typical CMRR of 116 dB with a guaranteed minimum of 98 dB. In a differential measurement of a bridge sensor or thermocouple, a 116 dB CMRR means a 1 V common-mode interference signal appears as only 0.5 µV at the output, allowing the amplifier to accurately resolve signal changes in the microvolt range even in electrically noisy industrial environments.
For a photodiode TIA operating from a 30 V supply, what bandwidth can ADA4627-1BRZ-RL provide?
With a gain-bandwidth product of approximately 19 MHz and the ability to operate from a dual 15 V supply up to a 30 V rail, the ADA4627-1BRZ-RL can support transimpedance gains of 1 MΩ while maintaining a signal bandwidth of around 19 Hz, or 100 kΩ feedback for a 190 Hz bandwidth. For higher-speed optical links requiring bandwidth above 1 MHz, a lower feedback resistor of around 10 kΩ keeps the TIA within the amplifier's 1.9 MHz bandwidth at that gain.
