Product details
Overview
AD7714ARZ-3 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, and 3 V single-supply operation. It delivers 0.0015% integral nonlinearity, <150 nV rms input noise, and supports filter notch frequencies down to 10 Hz - ideal for high-precision weigh scale and loop-powered transducer signal conditioning.
For engineers reviewing the AD7714ARZ-3 datasheet, AD7714ARZ-3 pinout, AD7714ARZ-3 application, or AD7714ARZ-3 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed alternative parts with documented differences, and supply-chain support for industrial instrumentation BOMs.
Technical Context
The AD7714ARZ-3 employs a charge-balancing sigma-delta modulator with on-chip digital filtering, enabling up to 24-bit no-missing-codes resolution at output data rates from 10 Hz to 1 kHz. Its programmable gain front end (1× to 128×) directly interfaces strain gauges and pressure transducers without external amplification.
It features a three-wire serial interface compatible with SPI™, QSPI™, and MICROWIRE™ protocols, supports self- and system calibration, and includes Schmitt-triggered SCLK/DIN inputs only in the Y-grade variant - not in the AD7714ARZ-3 (A-grade, –40°C to +85°C). The device uses separate analog (AVDD) and digital (DVDD) supplies, both rated 3.0–3.6 V for this variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 24 bits no missing codes (guaranteed ≤60 Hz filter notch; bipolar mode) |
| Integral Nonlinearity | ±0.0015% FSR max - ensures accurate endpoint linearity in precision weighing systems |
| Input Noise | <150 nV rms - enables sub-µV-level signal detection in low-level transducer applications |
| Supply Voltage | +3.0 V to +3.6 V AVDD/DVDD - optimized for 3 V loop-powered and portable industrial systems |
| Power Consumption | 0.27 mA AVDD typical (fCLK = 1 MHz, BUFFER = 0 V) - supports battery-operated designs |
| Filter Notch Range | Programmable from 10 Hz to 1 kHz - allows rejection of 50/60 Hz mains interference in field deployments |
| Common-Mode Rejection | 90 dB min at DC (typically 102 dB) - maintains accuracy despite ground shifts in noisy environments |
Pinout & Package
AD7714ARZ-3 is housed in a 24-lead SOIC (R-24) package, 0.3-inch wide, RoHS-compliant, with standard JEDEC MS-012AC footprint.

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 |
|---|---|---|---|
| AD7793BRUZ | 24-bit, 16-bit effective resolution @ 4.17 Hz; lower power (400 µA typ), integrated 2.5 V ref, but only 3-channel input | Better suited for ultra-low-power, single-sensor systems; lacks AD7714ARZ-3's five-channel flexibility and higher-speed modes | Select AD7793BRUZ when power budget is tighter and channel count is ≤3; retain AD7714ARZ-3 for multi-sensor, higher-throughput designs |
| ADS124S08IPW | 24-bit, 4kSPS max; integrated PGA (1–128×), 2.048 V ref, built-in burnout, but requires 5 V AVDD | Designed for 5 V industrial PLC I/O modules; incompatible with strict 3 V loop-powered systems | Choose ADS124S08IPW for new 5 V designs needing faster update rates; AD7714ARZ-3 remains optimal for legacy 3 V field instruments |
Compared with AD7793BRUZ and ADS124S08IPW, the AD7714ARZ-3 uniquely balances 24-bit integrity at 1 kHz, five-channel routing, and true 3 V operation - making it irreplaceable in portable, multi-sensor, loop-powered instrumentation where supply headroom and channel density are critical constraints.

FAQ
What is the maximum clock frequency supported by AD7714ARZ-3?
The AD7714ARZ-3 supports a master clock (MCLK IN) frequency of up to 2.5 MHz for specified performance. Operation above this limit may degrade noise, linearity, or timing margins. At 2.4576 MHz, the device achieves optimal filter settling and conversion accuracy per its datasheet characterization - and the BST bit in the Filter High Register must be set to '1' for gains ≥8 at this clock rate.
Does AD7714ARZ-3 include an internal voltage reference?
No, the AD7714ARZ-3 does not include an internal voltage reference. It requires an external differential reference voltage of +1.25 V (±1%) applied between REF IN(+) and REF IN(–). This reference sets the full-scale input range as ±VREF/GAIN (bipolar) or 0 to VREF/GAIN (unipolar), and must be stable and low-noise to preserve ADC accuracy.
Can AD7714ARZ-3 operate with separate analog and digital supply voltages?
Yes, AD7714ARZ-3 supports independent AVDD and DVDD supplies, both rated 3.0–3.6 V. This separation reduces digital switching noise coupling into the analog path. AGND and DGND must be connected at a single point near the device to maintain ground integrity - a critical layout requirement for achieving <150 nV rms noise performance.
How many analog input channels does AD7714ARZ-3 support, and how are they configured?
The AD7714ARZ-3 supports five pseudo-differential analog inputs (AIN1–AIN5) or three fully differential inputs (AIN1–AIN2, AIN3–AIN4, AIN5–AIN6), selected via configuration registers. Channel selection, gain (1×–128×), polarity, and filter settings are all software-controlled through its three-wire serial interface - enabling flexible multi-sensor routing without external multiplexers.
Is AD7714ARZ-3 pin-compatible with AD7714ARZ-5 or AD7714YRU?
No, AD7714ARZ-3 is not pin-compatible with AD7714ARZ-5 or AD7714YRU. While all share the same 24-pin SOIC (R-24) or TSSOP (RU-24) footprints, the AD7714YRU variant includes Schmitt-triggered SCLK/DIN inputs and operates over –40°C to +105°C - features absent in the AD7714ARZ-3. Electrical tolerances and reference voltage requirements also differ, requiring board-level validation for substitution.
