Analog Devices AD7710ANZ Datasheet
The AD7710ANZ is a complete, high-precision analog front end designed for low-frequency measurement applications. Utilizing an advanced Sigma-Delta conversion technique, it delivers an outstanding 24 bits of no-missing-codes performance alongside a remarkable plus/minus 0.0015% nonlinearity accuracy. Featuring a 2-channel programmable gain front end with software-configurable gains ranging from 1 to 128, the AD7710ANZ accepts low-level differential signals directly from strain gages, transducers, and thermocouples without requiring extensive external signal conditioning components.
The AD7710ANZ is currently In Stock and ready for immediate shipping at ICHOME. As a leading independent distributor of electronic components, we ensure 100% authenticity, comprehensive quality control, and rapid global delivery to keep your production lines moving without disruption.

Supply Chain and Procurement Insights
Lead Time and Market Trend: The AD7710 series represents a foundational product category within factory automation and precision weight scale systems. While traditional franchise lead times for legacy PDIP components can span from 16 to 26 weeks due to limited factory packaging line allocations, ICHOME maintains an active buffer stock of factory-sealed AD7710ANZ units. This allows us to circumvent standard factory lead times and provide international delivery within 3–5 business days, mitigating the risk of line-down situations for critical industrial infrastructure.
Outline Dimensions of AD7710ANZ
To facilitate rapid PCB layout verification for engineering teams, the 24-lead DIP pin arrangement is structured linearly to separate analog and digital pathways, minimizing cross-coupling noise:
Cross-Reference and Functional Alternatives of AD7710ANZ
When dealing with allocation bottlenecks or component obsolescence, procurement managers can consider the following functional equivalents or drops-ins:
AD7710ARZ (Direct Drop-in Replacement): This is the exact same silicon die and electrical performance, packaged in a 24-lead Small Outline Integrated Circuit (SOIC) surface-mount package. If your manufacturing line has transitioned to automated SMT assembly, the AD7710ARZ provides a seamless migration path from the through-hole PDIP version.
AD7712ANZ (Functional Equivalent): Also from Analog Devices, the AD7712 features an analog front end optimized for higher input spans and combines one differential high-input-span channel with an auxiliary input, utilizing a similar serial interface architecture.
Application of AD7710ANZ
The high resolution and robust programmable front-end architecture of the AD7710ANZ:
Industrial Weigh Scales and Strain Gages: Direct interface with load cells without requiring external drift-prone pre-amplifiers.
Process Control and Smart Transmitters: Ideal for 4-20mA loop-powered transmitters requiring highly stable internal 2.5V references and auto-zero calibration.
Laboratory Chromatography and Instrumentation: Delivers up to 23-bit usable dynamic range for gas and liquid analysis applications.
Thermocouple Data Acquisition: Differential inputs combined with background calibration compensate for extreme environmental temperature shifts.
What Is the Difference Between AD7710AN and AD7710ANZ?
The primary difference between the AD7710AN and the AD7710ANZ lies entirely in their environmental compliance and plating materials, as their internal electrical specifications and silicon layouts are identical.
The legacy AD7710AN uses traditional leaded (Sn/Pb) termination finishes on its pins.
The newer AD7710ANZ is a designated Pb-free (Lead-Free) part, where the "Z" suffix explicitly indicates compliance with environmental regulations such as RoHS (Restriction of Hazardous Substances) and REACH criteria mandated across the European Union and North American industrial markets.
