Frequently Asked Questions
What conversion speed and resolution does the AD7868ARZ provide for data acquisition applications?
The AD7868ARZ delivers 12-bit resolution with a conversion time of 3 µs, making it suitable for applications that require fast, high-accuracy analog-to-digital conversion. This combination supports sampling rates well above 100 kSPS in many system configurations.
Which industrial sensor interfaces benefit most from the AD7868ARZ track-and-hold architecture?
Applications using sensors with rapidly changing outputs, such as current-loop transmitters at 4 mA to 20 mA or voltage outputs up to 2.5 V, benefit from the on-chip track-and-hold amplifier. It freezes the input signal during the 12-bit conversion, preventing errors from signal movement during the 3 µs aperture window.
How does the AD7868ARZ compare to lower-resolution 8-bit ADCs for precision measurement boards?
The AD7868ARZ offers 12-bit resolution, providing 4096 quantization levels versus 256 levels for an 8-bit device. This 16x improvement in dynamic range reduces quantization error to under 0.025% of full scale, which is critical for medical and industrial measurements where ±0.1% accuracy is required.
What package does the AD7868ARZ use and how does it affect PCB layout density?
The AD7868ARZ is housed in a 28-pin SOIC-W (wide body) package with 1.27 mm pin pitch, occupying approximately 18.0 mm × 7.5 mm of board area. This surface-mount format supports automated assembly and fits standard SOIC footprints, enabling compact multi-channel data acquisition boards without through-hole drilling.
