Replacement verdict
Compatible functional replacement candidate
The AD7714ARZ-5 and AD7710ARZ are both 24-bit sigma-delta ADCs from Analog Devices in a 24-lead SOIC package, sharing a similar serial interface and signal-chain architecture, so the AD7714ARZ-5 can serve as a functional replacement candidate for the AD7710ARZ in many designs. However, the two devices differ in input channel configuration, programmable gain range, and supply voltage requirements, so the replacement must be validated against the target application's input multiplexing, gain settings, and power rail before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AD7714ARZ-5 | AD7710ARZ | Why it matters |
|---|---|---|---|
| Resolution (bits) | 24 | 24 | Both are 24-bit sigma-delta ADCs, so resolution is equivalent for high-precision measurement applications. |
| Number of input channels | 5 (differential/3 pseudo-differential configurable) | 2 (differential) | More input channels allow the AD7714 to multiplex multiple sensors without external switching, while the AD7710 suits single- or dual-channel designs. |
| PGA gain range | 1 to 128 | 1 to 128 | Identical programmable gain ranges mean both can directly interface with low-level signals such as thermocouples and bridge sensors. |
| Output data rate (max) | 1 kHz | 1.028 kHz | Similar maximum update rates make both suitable for low-frequency precision measurement, though slight differences affect timing budgets. |
| Supply voltage | 2.7 V to 5.25 V (single supply) | 5 V (single) or ±5 V (dual supply) | The AD7714 supports lower supply voltages for portable/low-power systems, while the AD7710 requires 5 V or bipolar supplies for wider signal swing. |
| Interface type | SPI-compatible serial (3-wire) | SPI-compatible serial (2-wire) | Both use serial interfaces, but pin/wire differences affect microcontroller wiring and firmware compatibility. |
| Package | 24-lead SOIC (wide body) | 24-lead SOIC (wide body) | Identical package footprint enables drop-in PCB compatibility between the two parts. |
| On-chip calibration | Yes (self and system calibration) | Yes (self and system calibration) | Both offer calibration features that reduce offset and gain errors, simplifying system-level accuracy design. |
| Operating temperature range | -40 °C to +85 °C | -40 °C to +85 °C | Identical industrial temperature ranges mean both are interchangeable for harsh-environment applications. |

Frequently asked questions
What are the primary functional differences between the AD7714ARZ-5 and the AD7710ARZ?
The AD7714ARZ-5 is a 24-bit sigma-delta ADC with a maximum output rate of 1 kSPS and a specified supply voltage of 5 V, featuring three differential input channels. The AD7710ARZ is a 24-bit sigma-delta ADC with a maximum output rate of 1.028 kSPS, operates from a 5 V or 10 V supply, and includes two differential input channels with an on-chip programmable gain amplifier (PGA) and a bidirectional serial port. Both are manufactured by Analog Devices in a 24-lead SOIC package.
Are the AD7714ARZ-5 and AD7710ARZ pin-compatible?
No. Although both devices are housed in a 24-lead SOIC (R-24) package, their pin functions differ. The AD7714ARZ-5 provides three differential analog input pairs and a dedicated interface for a 5 V supply, while the AD7710ARZ provides two differential input pairs with a different pin assignment for its PGA and serial interface. A direct drop-in replacement is not possible without verifying the pinout against the respective Analog Devices datasheets.
Can the AD7714ARZ-5 be used as a direct substitute for the AD7710ARZ in an existing design?
No. The two devices differ in the number of analog input channels (three differential pairs on the AD7714ARZ-5 versus two on the AD7710ARZ), supply voltage specifications, and pin assignments. Substitution requires a full review of the schematic, PCB layout, and firmware to confirm compatibility with the target device's register map and interface timing.
What is the maximum output data rate of each device?
The AD7714ARZ-5 supports a maximum output update rate of 1 kSPS. The AD7710ARZ supports a maximum output update rate of 1.028 kSPS. Both values are specified in the respective Analog Devices datasheets.
How many differential analog input channels does each device provide?
The AD7714ARZ-5 provides three differential analog input pairs (AIN1/AIN2, AIN3/AIN4, AIN5/AIN6). The AD7710ARZ provides two differential analog input pairs (AIN1/AIN2 and AIN3/AIN4). This difference affects channel count in multi-sensor designs.
Do both devices include an on-chip programmable gain amplifier (PGA)?
Yes. Both the AD7714ARZ-5 and the AD7710ARZ integrate a programmable gain amplifier. The AD7714ARZ-5 offers gain settings from 1 to 128, and the AD7710ARZ offers gain settings from 1 to 128 as well. The PGA allows direct interfacing with low-level transducer signals without external amplification.
What supply voltage does each device require?
The AD7714ARZ-5 is specified for operation from a single 5 V supply (the "-5" suffix denotes the 5 V version). The AD7710ARZ is specified for operation from a 5 V or 10 V supply, depending on the configuration. Designers must confirm the supply rail against the target device's datasheet before substitution.
Are both devices available in the same package type?
Yes. Both the AD7714ARZ-5 and the AD7710ARZ are offered in a 24-lead SOIC package (Analog Devices package code R-24). However, identical package outlines do not imply identical pin functions, so the PCB land pattern and pin assignments must be verified separately for each device.
