Key Features
- Maximum 130 µV input offset voltage and 1 µV/°C drift ensure sub-millivolt measurement accuracy over temperature
- 120 dB minimum common-mode rejection ratio (CMRR) suppresses noise and ground shifts in instrumentation front ends
- 1 nA maximum bias current prevents loading errors when interfacing with high-impedance sensors or resistor bridges
- Wide 3 V to 36 V supply range in a 5-pin SOT-23 package enables precision use in both battery-powered and industrial 24 V systems
Applications
The AD8677AUJZ-R2 is suited for precision strain-gauge bridges, thermocouple amplifiers, and medical-grade sensor interfaces where the 130 µV maximum offset and 120 dB CMRR maintain measurement accuracy below 0.1% full-scale across the industrial temperature range. Its 1 nA bias current and SOT-23 package also make it a natural choice for portable pH meters, precision current sources, and ADC input buffers in handheld scientific instruments.

Frequently Asked Questions
What is the maximum input offset voltage of the AD8677AUJZ-R2, and how does it affect measurement accuracy?
The AD8677AUJZ-R2 guarantees a maximum input offset voltage of 130 µV at 25°C, which translates to less than 0.013% full-scale error on a 1 V input range. Combined with a drift of 1 µV/°C, the total offset over a 100°C industrial temperature span remains below 230 µV, making it suitable for 12-bit and 14-bit ADC front ends without manual calibration.
How does the 120 dB CMRR of the AD8677AUJZ-R2 benefit a differential sensor measurement circuit?
A CMRR of 120 dB means the AD8677AUJZ-R2 attenuates common-mode interference by a factor of one million, so a 1 V mains-frequency noise signal common to both inputs appears as only 1 µV of error at the output. This level of rejection is essential in strain-gauge bridges, 4-wire RTD amplifiers, and industrial 4–20 mA receiver circuits where ground potential differences of hundreds of millivolts are common.
What supply voltage does the AD8677AUJZ-R2 require, and can it run from a single 5 V rail?
The AD8677AUJZ-R2 operates from a total supply of 3 V to 36 V, which covers single 5 V, dual ±5 V, dual ±12 V, and 24 V single-supply configurations. On a single 5 V rail the input common-mode range and output swing allow direct connection to ratiometric sensors and resistor bridges without a negative rail, simplifying power-supply design in battery-operated instruments.
For a high-impedance pH electrode amplifier, why is the AD8677AUJZ-R2 input bias current specification critical?
A pH electrode presents source impedances of 10 MΩ to 1 GΩ, so the amplifier's 1 nA maximum bias current creates at most 1 mV of offset error across a 1 MΩ source—far less than the electrode's own chemical noise. Higher-bias-current op-amps with 100 nA or more would introduce 100 mV errors that render the pH reading meaningless, so the AD8677AUJZ-R2's 0.001 µA specification is essential for accurate pH measurement.
