What are the key features of XOPA862IDT?
- 120 dB typical CMRR with 100 dB minimum for superior common-mode noise rejection in differential signal chains
- Ultra-low input offset voltage of 200 µV max enabling high-accuracy single-ended to differential conversion
- High input impedance voltage-feedback architecture ideal for driving ADC inputs from sensors and signal sources
What is XOPA862IDT used for?
XOPA862IDT is designed for precision data acquisition front-ends that need to convert single-ended sensor signals to differential form before an ADC, maintaining low noise and high common-mode rejection. It is used in medical instrumentation, industrial measurement, and communications equipment where signal integrity over 12.6 V supply rails is critical. The 8-pin SOIC package simplifies layout in analog signal conditioning boards.

Frequently Asked Questions
What is the CMRR specification of XOPA862IDT and why does it matter for differential signal designs?
XOPA862IDT achieves a typical common-mode rejection ratio of 120 dB with a guaranteed minimum of 100 dB. This high CMRR ensures that noise and interference present on both input lines are rejected effectively, which is critical in precision measurement systems such as industrial sensors and medical ECG front-ends where common-mode interference can reach several volts.
How does the 200 µV maximum input offset voltage of XOPA862IDT affect precision ADC driver designs?
With a maximum input offset voltage of only 200 µV, XOPA862IDT introduces minimal DC error at the ADC input in single-ended-to-differential conversion stages. For a 12-bit ADC on a 3.3 V reference, a 200 µV offset represents less than 0.25 LSB error, preserving the dynamic range and accuracy required in precision industrial and instrumentation designs.
What is the supply voltage for XOPA862IDT, and which ADC interface circuits does it suit?
XOPA862IDT operates from a 12.6 V supply rail and is well matched to ADC driver applications in industrial systems powered from 12 V or ±5 V split supplies. Its voltage-feedback architecture with 3.1 µA max bias current keeps loading on high-impedance sources minimal, making it suitable for driving SAR and pipeline ADCs in data acquisition cards and sensor interfaces.
When would XOPA862IDT be selected over a standard op-amp in a signal chain design?
XOPA862IDT is preferred over standard single-output op-amps when the design requires a fully differential output to drive differential ADC inputs directly, minimizing even-order harmonic distortion. Its integrated single-ended-to-differential conversion eliminates the need for an external balun or a two-op-amp stage, reducing component count and board area by at least 2 passive components and one additional IC in typical 16-bit ADC front-end designs.
