Product details
Overview
AD8230YRZ-REEL7 from Analog Devices is a zero-drift, rail-to-rail precision instrumentation amplifier optimized for high-accuracy dc-coupled sensor signal conditioning. It delivers 110 dB minimum CMR at 60 Hz, 10 μV max RTI offset (±5 V), and 50 nV/°C max offset drift across −40°C to +125°C - enabling stable thermocouple and bridge transducer measurements in noisy industrial environments.
For engineers reviewing the AD8230YRZ-REEL7 datasheet, AD8230YRZ-REEL7 pinout, AD8230YRZ-REEL7 application, or AD8230YRZ-REEL7 equivalent, this page provides verified technical context, gain-programmable architecture details, rail-to-rail input/output behavior, and real-world implementation constraints for precision analog front-ends.
Technical Context
The AD8230YRZ-REEL7 uses a dual-stage auto-zeroing topology: a differential sample-and-hold preamplifier followed by a gain amplifier, both dynamically corrected at 6 kHz internal clock rate. This architecture suppresses 1/f noise and achieves 3 μV p-p (0.1–10 Hz) low-frequency noise while maintaining rail-to-rail common-mode input range up to ±8 V.
Gain is set by two external matched resistors (RF and RG), supporting 101–1000 V/V range with ≤20 ppm nonlinearity and ≤0.05% gain error. Input bias current remains below 1 nA, and output swing reaches within 100 mV of rails under load - critical for single-supply operation down to +8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage (RTI) | 10 μV max @ ±5 V - enables sub-μV-level dc accuracy without trimming in thermocouple applications |
| Offset Drift | 50 nV/°C max - ensures <1 μV total drift over full −40°C to +125°C industrial range |
| CMR @ 60 Hz | 110 dB min with 1 kΩ source imbalance - rejects line noise in remote bridge sensors |
| Rail-to-Rail Input Range | −VS to +VS (±4 V to ±8 V) - accommodates >±7 V ground differentials in automotive diagnostics |
| Low-Frequency Noise | 3 μV p-p (0.1–10 Hz) - supports high-resolution strain gauge digitization without averaging |
| Supply Range | Dual: ±4 V to ±8 V; Single: +8 V to +16 V - allows direct interface with 12 V industrial rails |
| Quiescent Current | 3.5 mA max over temperature - enables low-power battery-operated sensor nodes |
Pinout & Package
AD8230YRZ-REEL7 is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 × 4.00 mm body dimensions. Thermal resistance θJA = 121°C/W on 4-layer JEDEC board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: –IN | Inverting input | Differential input node; accepts rail-to-rail common-mode voltage up to ±8 V |
| 2: +IN | Non-inverting input | Differential input node; matched parasitic capacitance (70 pF) enables high CMRR |
| 3: VREF2 | Output common-mode reference | High-impedance node setting output DC level; must be star-connected to ground or reference |
| 4: –VS | Negative supply | Accepts −4 V to −8 V; internal ESD diodes clamp input to −0.6 V beyond rail |
| 5: +VS | Positive supply | Accepts +4 V to +8 V; requires 0.1 μF ceramic bypass capacitor placed adjacent to pin |
| 6: VOUT | Differential output | Rail-to-rail swing (−VS + 0.1 V to +VS − 0.2 V); drives 10 kΩ load with <2 V/μs slew rate |
| 7: RG | Gain-setting resistor terminal | Connects external RG; junction leakage affects offset drift - keep RF small for best tempco |
| 8: VREF1 | Internal reference bias | Current-drawing node for internal voltage references; must be star-connected to ground |
Key Features
| Feature | Design Value |
|---|---|
| Auto-zeroing architecture | 6 kHz internal sampling eliminates 1/f noise and reduces RTI offset drift to 50 nV/°C |
| Two-resistor gain programming | RF/RG ratio sets gain from 101–1000 V/V with TC-matched stability superior to single-resistor IAs |
| Rail-to-rail common-mode input | ±8 V range enables operation with large ground potential differences in distributed sensor systems |
| Level-shifted output capability | VREF1/VREF2 pins allow precise output biasing from −VS + 3.5 V to +VS − 2.5 V without external op amps |
| Industrial temperature grade | Specified performance from −40°C to +125°C - qualified for engine bay and factory-floor deployments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar instrumentation amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8421ARMZ | Fixed gain (1–1000), no external resistors; 120 dB CMR; 3 nV/√Hz noise density | Better high-frequency CMR and lower broadband noise, but lacks programmable gain flexibility | Select when fixed-gain simplicity and higher-speed rejection (>10 kHz) outweigh resistor network design effort |
| INA333AIDR | Single-supply only (+1.8 V to +5.5 V); 50 μV max offset; 0.15 μV/°C drift | Optimized for ultra-low-voltage battery-powered devices, not industrial ±8 V systems | Select for portable medical sensors or IoT nodes where supply headroom is constrained to <5.5 V |
Compared with AD8230YRZ-REEL7, AD8421ARMZ offers superior high-frequency CMR without external components but forfeits gain adjustability, while INA333AIDR enables sub-2 V operation at the cost of reduced input voltage range and thermal robustness - making AD8230YRZ-REEL7 optimal for wide-rail, programmable, high-stability industrial sensing.

FAQ
What is the maximum differential input voltage for AD8230YRZ-REEL7?
The AD8230YRZ-REEL7 has a maximum differential input voltage of 750 mV. Exceeding this limit may cause gain compression or increased nonlinearity, even though the device does not phase invert when overdriven. This constraint applies across all supply voltages and temperatures, and is independent of the common-mode voltage range.
Can AD8230YRZ-REEL7 operate from a single +12 V supply?
Yes, AD8230YRZ-REEL7 supports single-supply operation from +8 V to +16 V. When powered from +12 V, the negative supply rail is referenced to ground, and the input common-mode range extends from 0 V to +12 V. Output swing remains rail-to-rail (0.1 V to 11.8 V typical), provided VREF1 and VREF2 are properly grounded.
How does the AD8230YRZ-REEL7 achieve its 50 nV/°C offset drift specification?
The AD8230YRZ-REEL7 achieves 50 nV/°C max offset drift through continuous auto-zeroing at 6 kHz, which dynamically corrects input stage mismatches. This architecture cancels both first-order and higher-order temperature-dependent errors in the preamplifier and gain amplifier stages - unlike chopper-stabilized amplifiers that introduce switching transients.
What is the role of Pin 7 (RG) in AD8230YRZ-REEL7, and why does resistor selection affect drift?
Pin 7 (RG) connects to the gain-setting resistor that forms part of the feedback network determining overall gain. Junction leakage current at this pin contributes directly to offset voltage drift; using smaller RF values (e.g., 10 kΩ instead of 100 kΩ) minimizes this effect, as confirmed by Figure 33 in the datasheet showing reduced drift with lower RF.
Does AD8230YRZ-REEL7 require external clocking or support synchronization with other devices?
No, AD8230YRZ-REEL7 uses an internal 6 kHz oscillator and requires no external clock. Its sampling phases (A and B) are fully self-contained and non-synchronizable. This eliminates timing coordination overhead but means multiple AD8230YRZ-REEL7 units in one system may exhibit beat frequencies - mitigated via star-grounded supplies per Figure 38.
