Product details
Overview
AD7714YRZ-REEL from Analog Devices is a 24-bit sigma-delta analog-to-digital converter (ADC) with integrated programmable-gain amplifier (PGA), five-channel pseudo-differential or three-channel fully differential input architecture, and on-chip digital filtering. It delivers 0.0010% linearity error, operates from +2.7 V to +3.3 V or +4.75 V to +5.25 V, and supports –40°C to +105°C industrial temperature range - ideal for high-accuracy loop-powered pressure transducers and portable weigh scales.
For engineers reviewing the AD7714YRZ-REEL datasheet, AD7714YRZ-REEL pinout, AD7714YRZ-REEL application, or AD7714YRZ-REEL equivalent, key selection considerations include its 24-bit no-missing-codes performance, Schmitt-triggered SCLK/DIN inputs for noise immunity, low 226 µA typical active current, TSSOP-24 package compatibility, and support for self/system/background calibration in microcontroller-based signal conditioning systems.
Technical Context
The AD7714YRZ-REEL employs a charge-balancing sigma-delta modulator with a programmable digital filter whose first notch frequency is software-configurable - enabling precise trade-offs between resolution (up to 24 bits), output data rate (e.g., 100 Hz at 60-Hz rejection), and settling time. Its front-end PGA offers gains of 1–128 across five analog input channels, configurable as either three fully differential or five pseudo-differential inputs.
It features a three-wire serial interface compatible with SPI™, QSPI™, and MICROWIRE™ protocols, with separate AVDD (+2.7 V to +3.3 V or +4.75 V to +5.25 V) and DVDD (+2.7 V to +5.25 V) supplies. The device includes dedicated reference inputs (REF IN(+) and REF IN(–)), AGND/DGND separation, and Schmitt-triggered SCLK/DIN inputs - critical for robust operation in noisy industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision sigma-delta ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7718BRUZ | 24-bit, 8-channel, 1.17 MSPS output rate; higher power (1.2 mA); SPI-only interface; no Schmitt triggers | Better suited for high-channel-count PLC modules requiring faster updates; less suitable for ultra-low-power portable use | Select AD7718BRUZ when >5 inputs or >100 Hz update rate is required; AD7714YRZ-REEL remains optimal for <350 µA power budgets and 50/60 Hz rejection-critical designs |
| ADS1258IPWR | 24-bit, 8-channel, 125 kSPS; integrated oscillator; no PGA; lower linearity (±0.002%); 3.3 V only | Targeted at cost-sensitive, moderate-accuracy data loggers; lacks programmable filter notches for precise 50/60 Hz rejection | Choose ADS1258IPWR for simplified layout and lower BOM cost where ±0.002% linearity suffices; AD7714YRZ-REEL preferred when 0.0010% linearity and flexible gain/filtering are mandatory |
Compared with AD7714YRZ-REEL, AD7718BRUZ offers higher channel count and speed but doubles power consumption and omits Schmitt-triggered inputs, while ADS1258IPWR reduces system complexity at the expense of linearity and 50/60 Hz rejection capability - making AD7714YRZ-REEL uniquely balanced for low-power, high-accuracy, noise-immune industrial sensing.

FAQ
What is the maximum sampling rate achievable with the AD7714YRZ-REEL at gain = 1 and 60 Hz filter notch?
The AD7714YRZ-REEL achieves a maximum output data rate of 100 Hz when configured with a 60 Hz filter notch and gain = 1. This is derived from its fCLK IN = 2.4576 MHz master clock and internal decimation ratio - delivering 24-bit no-missing-codes performance with 100 dB 60 Hz rejection. At this setting, the AD7714YRZ-REEL settles fully within one cycle, enabling synchronized multi-channel acquisition in industrial control loops.
Does the AD7714YRZ-REEL support both unipolar and bipolar input ranges, and how is the mode selected?
Yes, the AD7714YRZ-REEL supports both unipolar (0 to +VREF/GAIN) and bipolar (±VREF/GAIN) input ranges. The mode is selected by setting the B/U bit in the Filter High register: B/U = 1 configures unipolar mode with binary coding; B/U = 0 configures bipolar mode with offset binary coding. This register-based control allows dynamic reconfiguration during operation without hardware changes - a key feature for adaptive sensor interfaces in the AD7714YRZ-REEL.
How does the AD7714YRZ-REEL handle reference voltage variations, and what are the specified VREF ranges?
The AD7714YRZ-REEL accepts a differential reference voltage (REF IN(+) – REF IN(–)) of 1.25 V ±1% when operating from a 3 V supply, or 2.5 V ±1% when operating from a 5 V supply. The device functions with lower VREF values (down to 1 V at 3 V AVDD, 1.75 V at 5 V AVDD), though specified performance requires the nominal reference. Internal calibration compensates for VREF drift, ensuring that AD7714YRZ-REEL maintains 0.0010% linearity even with minor reference tolerance deviations.
Can the AD7714YRZ-REEL perform background calibration while continuously converting data?
Yes, the AD7714YRZ-REEL supports background calibration - a mode where zero-scale calibration occurs automatically during normal conversion cycles without interrupting data flow. This feature relies on internal timing control and does not require host processor intervention. Background calibration corrects for zero-drift over temperature and time, preserving the AD7714YRZ-REEL's ±0.0010% linearity specification across its full –40°C to +105°C operating range without halting measurements.
What packaging and tape-and-reel options are available for the AD7714YRZ-REEL?
The AD7714YRZ-REEL is supplied exclusively in a 24-lead TSSOP package (RU-24) with RoHS-compliant, lead-free finish, and shipped in standard 13-inch tape-and-reel format (REEL designation). It is not offered in DIP (N-24), SOIC (R-24), or SSOP (RS-28) variants - the "YRZ" suffix explicitly denotes the TSSOP-24 package with extended temperature qualification. This packaging enables high-density PCB layouts while maintaining thermal performance required for the AD7714YRZ-REEL's low-drift operation.
