Frequently Asked Questions
How does the 110 dB CMRR of the ADA4004-1ARJZ-R2 benefit differential measurement accuracy in a bridge sensor circuit?
The ADA4004-1ARJZ-R2 achieves a 110 dB typical common-mode rejection ratio, meaning a 1 V common-mode interference signal at the input is attenuated to approximately 3 µV at the output. In a Wheatstone bridge pressure or load cell circuit operating with a 5 V excitation and a 1 mV full-scale differential output, this 110 dB CMRR prevents mains-frequency noise from masking the bridge signal and maintains better than 0.1% measurement accuracy.
Which precision analog applications benefit from the ADA4004-1ARJZ-R2's 0.09 µA bias current in SOT-23-5?
The ADA4004-1ARJZ-R2's 0.09 µA maximum bias current at 25°C (0.165 µA maximum over temperature) is critical for high-impedance sensor interfaces such as pH electrodes with 100 MΩ source impedance, where a 0.09 µA bias current would generate only 9 mV of offset error. Photodiode transimpedance amplifiers using 10 MΩ feedback resistors also benefit, as the 0.09 µA bias causes less than 1 mV output offset from the bias current alone.
For a precision 16-bit DAC output buffer, how does the ADA4004-1ARJZ-R2's 12 MHz bandwidth affect settling time?
At a gain of 1 V/V the ADA4004-1ARJZ-R2 has a 12 MHz unity-gain bandwidth, yielding a slew rate sufficient to settle a full-scale 16-bit DAC step within microseconds. For a 10 V full-scale 16-bit DAC with 153 µV LSB, the amplifier's low offset voltage and 95 dB minimum CMRR ensure the buffered output remains within 1 LSB after the settling transient, supporting precision waveform generation and calibration references.
When would a designer choose the ADA4004-1ARJZ-R2 over a rail-to-rail output op-amp for a 5 V single-supply measurement circuit?
A designer chooses the ADA4004-1ARJZ-R2 when output voltage swing reaching within millivolts of the supply rails is not required but maximum CMRR and minimum bias current are essential. In 5 V single-supply bridge sensor amplifiers where the output operates between 0.5 V and 4.5 V, the 110 dB CMRR and 0.09 µA bias current of the ADA4004-1ARJZ-R2 outperform typical rail-to-rail CMOS op-amps which offer only 80–90 dB CMRR and higher input noise.
