Product details
Overview
ADA4004-1ARJZ-R7 from Analog Devices is a single-channel, precision operational amplifier optimized for low-noise, high-accuracy 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, 125 µV max offset voltage (±15 V), and operates across −40°C to +125°C - enabling use in thermocouple amplification, reference buffering, and high-fidelity instrumentation front-ends.
For engineers reviewing the ADA4004-1ARJZ-R7 datasheet, ADA4004-1ARJZ-R7 pinout, ADA4004-1ARJZ-R7 application, or ADA4004-1ARJZ-R7 equivalent, key selection criteria include its 1.8 nV/√Hz noise floor, rail-to-rail output swing capability (±3.6 V at ±5 V supply), 0.7 µV/°C offset drift, 5-Lead SOT-23 package footprint, and guaranteed performance over industrial temperature range.
Technical Context
The ADA4004-1ARJZ-R7 employs Analog Devices' iPolar™ process to achieve ultra-low voltage noise while maintaining low power (1.7 mA per amplifier) and high DC precision. Its architecture features a 6 Hz 1/f noise corner, enabling stable low-frequency operation in precision sensor interfaces and PLL loop filters.
Designed for dual-supply operation from ±5 V to ±15 V, it supports wide common-mode input range (±12.5 V at ±15 V), high CMRR (113 dB typ), and robust PSRR (118 dB typ), making it suitable for noisy industrial environments where signal integrity and long-term stability are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 1.8 nV/√Hz at 1 kHz - enables sub-µV-level resolution in low-amplitude sensor signals |

Pinout & Package
ADA4004-1ARJZ-R7 is housed in a 5-Lead SOT-23 (RJ-5) package with exposed pad connected to V– for thermal and noise performance. Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Drives loads ≥2 kΩ; capable of ±3.6 V swing at ±5 V supply |
| 2 (V–) | Negative supply rail | Reference for internal biasing; exposed pad must be soldered to PCB ground plane |
| 3 (+IN) | Non-inverting input | High-impedance node (IB ≤90 nA); accepts common-mode voltages up to ±12.5 V |
| 4 (–IN) | Inverting input | Used in standard op-amp configurations (e.g., inverting amp, transimpedance) |
| 5 (V+) | Positive supply rail | Accepts +5 V to +15 V; PSRR of 118 dB suppresses supply ripple |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8675ARMZ | Lower noise (1.1 nV/√Hz), higher supply current (3.5 mA), MSOP-8 only | Better for ultra-low-noise audio; less suitable for space-constrained SOT-23 layouts | Select AD8675ARMZ when noise budget is tighter and board area allows larger package |
| OP27GSZ-REEL7 | Higher noise (3.0 nV/√Hz), wider bandwidth (8 MHz), SOIC-8 only, no extended temp grade | Legacy industrial use; lacks −40°C to +125°C rating and low 1/f corner | Choose OP27GSZ-REEL7 only for cost-sensitive, non-extended-temp designs where 3 nV/√Hz is acceptable |
Compared with AD8675ARMZ and OP27GSZ-REEL7, ADA4004-1ARJZ-R7 uniquely combines 1.8 nV/√Hz noise, 5-Lead SOT-23 footprint, and full industrial temperature support - making it optimal for miniaturized, high-reliability sensor signal chains where layout area and thermal stability are constrained.

FAQ
What is the maximum supply voltage for ADA4004-1ARJZ-R7?
The ADA4004-1ARJZ-R7 supports absolute maximum supply voltage of ±18 V or +36 V total. Its specified operating range is ±5 V to ±15 V, with full performance guaranteed across this range at temperatures from −40°C to +125°C. Exceeding ±18 V risks permanent damage per Absolute Maximum Ratings table.
Does ADA4004-1ARJZ-R7 have rail-to-rail output capability?
ADA4004-1ARJZ-R7 does not provide true rail-to-rail output swing. At ±5 V supply, it delivers ±3.6 V into 2 kΩ (VOH = +3.9 V typ, VOL = −3.55 V typ), achieving >90% of the available voltage range. This near-rail performance maximizes dynamic range for 12-bit and 16-bit ADC interfacing without external level-shifting.
What is the 1/f noise corner frequency of ADA4004-1ARJZ-R7?
The ADA4004-1ARJZ-R7 has a 1/f noise corner frequency of 6 Hz, as confirmed in the General Description section. This low corner enables stable DC and low-frequency operation - critical for thermocouple amplification, strain gauge bridges, and other precision DC-coupled applications where long-term offset stability is required.
Is the exposed pad on ADA4004-1ARJZ-R7 internally connected?
No - the exposed pad on ADA4004-1ARJZ-R7 (5-Lead SOT-23/RJ-5) is not internally connected to any die node. Per Figure 1 and Note 2 in the datasheet, it is recommended that the exposed pad be connected to V– to improve thermal dissipation and reduce noise coupling. Failure to connect it may degrade thermal performance and increase susceptibility to EMI.
How does ADA4004-1ARJZ-R7 compare to ADA4004-1ARZ in terms of performance?
ADA4004-1ARJZ-R7 (SOT-23) and ADA4004-1ARZ (SOIC-8) share identical electrical specifications - same noise, bandwidth, offset, drift, and temperature range. The only differences are package size, thermal resistance (θJA = 230°C/W for RJ-5 vs. 177°C/W for R-8), and pinout. Both are drop-in functional replacements where layout permits.
