Product details
Overview
ADA4004-2ARZ-RL from Analog Devices is a dual-channel precision operational amplifier optimized for low-noise, high-gain signal conditioning in ±5 V to ±15 V systems. It delivers 1.8 nV/√Hz voltage noise density, 12 MHz gain bandwidth, 120 dB open-loop gain, and 125 µV maximum offset voltage at ±15 V, serving critical roles in thermocouple amplification, reference buffering, and high-fidelity filter blocks.
For engineers reviewing the ADA4004-2ARZ-RL datasheet, ADA4004-2ARZ-RL pinout, ADA4004-2ARZ-RL application, or ADA4004-2ARZ-RL equivalent, key selection factors include its 1.8 nV/√Hz noise floor, −40°C to +125°C operating range, dual SOIC-8 package, rail-to-rail output swing limitations (±3.6 V at ±5 V supply), and compatibility with precision DC-coupled instrumentation requiring <1 µV/°C drift.
Technical Context
The ADA4004-2ARZ-RL employs Analog Devices' iPolar™ process to achieve simultaneous low noise (1.8 nV/√Hz) and low power (2.2 mA per amplifier), with a 6 Hz 1/f noise corner enabling stable DC performance. Its architecture supports unity-gain-stable operation with 48° phase margin and delivers full-swing output into 2 kΩ loads across the full temperature range.
Designed for bipolar supply operation only (±5 V to ±15 V), it features input voltage range of ±12.5 V at ±15 V supplies, CMRR ≥110 dB, PSRR ≥110 dB, and guaranteed performance over −40°C to +125°C without derating-making it suitable for industrial control loops and ATE front ends where thermal stability and long-term offset drift (<0.7 µV/°C typical) are critical.
Key Specifications

|---|---|
| Voltage Noise Density | 1.8 nV/√Hz at 1 kHz - enables sub-µV signal resolution in 10 kHz bandwidths without dominant noise contribution |
| Gain Bandwidth Product | 12 MHz - supports stable closed-loop gains up to 100× at 120 kHz or unity gain at 12 MHz |
| Input Offset Voltage | 125 µV max at ±15 V - ensures ≤0.001% error in 12 V full-scale precision measurement paths |
| Supply Current per Amp | 2.2 mA max at −40°C to +125°C - allows dual-amplifier operation within 4.4 mA total budget for battery-sensitive designs |
| Common-Mode Rejection | 110 dB min - rejects >100,000:1 common-mode interference in differential sensor interfaces |
| Output Voltage Swing | ±13.2 V min at ±15 V supply into 2 kΩ - delivers >90% of rail-to-rail dynamic range for analog-to-digital conversion stages |
| Offset Drift | 0.7 µV/°C typical - contributes <84 µV total drift over 120°C industrial temperature span |
Pinout & Package
ADA4004-2ARZ-RL is housed in an 8-lead SOIC_N (R-8) package with exposed pad not connected internally; the package measures 5.00 mm × 4.00 mm × 1.50 mm and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Capable of sourcing/sinking ±10 mA; requires local 100 nF bypass capacitor to V+ and V− |
| 2: –IN A | Inverting input A | High-impedance node (90 nA max bias current); sensitive to PCB leakage and guarding requirements |
| 3: +IN A | Non-inverting input A | Matched to –IN A for CMRR optimization; must be routed with equal trace length and impedance |
| 4: V− | Negative supply rail | Reference for all internal circuitry; exposed pad (if present) must connect to this net for thermal performance |
| 5: +IN B | Non-inverting input B | Independent of Channel A; no crosstalk specification provided but channel separation >80 dB at 1 kHz |
| 6: –IN B | Inverting input B | Electrically isolated from Channel A inputs; shares same V− and V+ rails |
| 7: OUT B | Amplifier B output | Functionally identical to OUT A; supports independent feedback networks per channel |
| 8: V+ | Positive supply rail | Must be decoupled with ≥0.1 µF ceramic capacitor placed <2 mm from pin; accepts ±5 V to ±15 V |

Applications
| Thermocouple Amplification | Reference Buffering |
|---|---|
Use Scenario: Amplifying µV-level outputs from Type K thermocouples in furnace controllers with cold-junction compensation. IC Role / Device Role / Timing Role: First-stage low-noise instrumentation amplifier with gain ≥1000, DC-coupled to preserve absolute temperature accuracy. Use Value: 1.8 nV/√Hz noise ensures <0.1°C RMS noise floor in 10 Hz bandwidth; 0.7 µV/°C drift prevents calibration drift during thermal cycling. |
Use Scenario: Buffering 2.5 V precision voltage references (e.g., ADR4525) driving multiple ADCs and DACs in data acquisition modules. IC Role / Device Role / Timing Role: Unity-gain voltage follower isolating reference source from load-induced errors and supply ripple. Use Value: 120 dB open-loop gain guarantees <0.001% gain error; PSRR ≥110 dB suppresses supply noise coupling into reference path. |

IC Role / Device Role / Timing Role: Dual-channel op amp providing both integrator and gain stages in single-package solution. Use Value: 12 MHz GBP enables stable 1 kHz filter design with <0.05 dB passband ripple; matched channels reduce component count vs. discrete solutions. |
Use Scenario: Conditioning 4–20 mA loop signals in PLC analog input modules with isolation and linearization. IC Role / Device Role / Timing Role: Transimpedance amplifier converting loop current to voltage, followed by gain/offset stage for ADC interface. Use Value: 125 µV max offset ensures <0.06% full-scale error in 5 V output range; CMRR ≥110 dB rejects common-mode noise from field wiring. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8676ARZ | Higher 2.8 nV/√Hz noise; lower 10 MHz GBP; 10x higher input bias current (2 pA vs. 90 nA) | Better for ultra-low-input-current applications (e.g., photodiode amps); less suitable for low-noise thermocouple amps | Select AD8676ARZ only when femtoampere bias current outweighs 1.0 nV/√Hz noise penalty |
| OP2177ARZ | Lower 3.5 nV/√Hz noise; wider 1.3 MHz GBP; higher 1.2 mA supply current; limited to ±15 V max supply | Preferred for low-power, low-bandwidth precision apps (e.g., strain gauge bridges); cannot operate at ±5 V | Choose OP2177ARZ for sub-1 MHz applications needing <4 nV/√Hz noise and <1.5 mA total supply current |
Compared with AD8676ARZ and OP2177ARZ, ADA4004-2ARZ-RL uniquely balances 1.8 nV/√Hz noise, 12 MHz bandwidth, and ±5 V compatibility-making it optimal for dual-channel, wide-supply-range, low-drift instrumentation where neither ultra-low bias current nor ultra-low power is the primary constraint.

FAQ
What is the maximum supply voltage for ADA4004-2ARZ-RL?
The ADA4004-2ARZ-RL supports a maximum total supply voltage of ±18 V (or +36 V single supply), with absolute maximum ratings specifying ±18 V on V+ and V− pins. Operation is fully characterized from ±5 V to ±15 V; exceeding ±15 V may impact long-term reliability and is not recommended for production use without validation.
Does ADA4004-2ARZ-RL support single-supply operation?
No, ADA4004-2ARZ-RL is specified and characterized exclusively for dual-supply operation (±5 V to ±15 V). Its input common-mode range does not extend to the negative rail, and output swing is asymmetric under single-supply conditions. For true single-supply applications, consider rail-to-rail input/output op amps like AD8605 or ADA4661-2.
What is the thermal resistance (θJA) of ADA4004-2ARZ-RL in its SOIC-8 package?
The ADA4004-2ARZ-RL in 8-lead SOIC_N (R-8) package has a junction-to-ambient thermal resistance (θJA) of 177°C/W when soldered to a 4-layer JEDEC-standard PCB with zero airflow and exposed paddle connected to V−. This value assumes proper layout per Analog Devices' AN-820 guidelines.
Is the exposed pad on ADA4004-2ARZ-RL electrically connected?
No-the ADA4004-2ARZ-RL in SOIC-8 (R-8) packaging does not feature an exposed thermal pad. The exposed pad reference in the datasheet applies only to MSOP (RM-8) and LFCSP (CP-16-23) variants. SOIC-8 units rely solely on lead-frame conduction for thermal dissipation.
What is the guaranteed minimum open-loop gain for ADA4004-2ARZ-RL at +125°C?
At −40°C to +125°C and ±15 V supply, ADA4004-2ARZ-RL guarantees a minimum open-loop gain of 250 V/mV (108 dB). This ensures predictable closed-loop accuracy and stability margins across the full industrial temperature range without gain degradation.
