Product details
Overview
AD8674ARUZ-REEL from Analog Devices is a precision quad operational amplifier optimized for low-noise, high-accuracy signal conditioning in instrumentation and sensor interfaces. It delivers 2.8 nV/√Hz voltage noise, 10 MHz gain bandwidth, 75 µV max offset voltage, 12 nA max input bias current, and operates from ±5 V to ±15 V dual supplies. It is used in GPS receiver filters and professional audio preamplifiers where ultralow noise and dc precision are critical.
For engineers reviewing the AD8674ARUZ-REEL datasheet, AD8674ARUZ-REEL pinout, AD8674ARUZ-REEL application, or AD8674ARUZ-REEL equivalent, key selection criteria include verified 14-lead TSSOP package compatibility, channel separation >130 dB at 1 kHz, output drive capability into 600 Ω, and guaranteed operation across –40°C to +85°C industrial temperature range.
Technical Context
The AD8674ARUZ-REEL employs a precision bipolar input stage enabling ultralow voltage noise (2.8 nV/√Hz) while maintaining low input bias current (12 nA max). Its 10 MHz gain bandwidth and 4 V/µs slew rate support stable unity-gain operation with capacitive loads up to 1000 pF without phase reversal.
It features rail-to-rail output swing within 1.2 V of rails (±15 V supply), 120 dB min open-loop gain, and 106–115 dB PSRR - all specified over its full –40°C to +85°C operating range. Channel separation is –130 dB at 1 kHz, confirming minimal crosstalk in multi-channel precision systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 2.8 nV/√Hz @ 1 kHz - enables high-fidelity amplification of microvolt-level sensor signals without adding significant noise floor |
| Gain Bandwidth Product | 10 MHz - supports stable closed-loop designs up to ~1 MHz at G = 10, suitable for anti-aliasing and active filter stages |
| Input Offset Voltage | 75 µV max - ensures <0.0075% gain error in 1 V full-scale instrumentation amplifiers without trimming |
| Supply Current per Amp | 3.5 mA typ - balances low-noise performance with moderate power consumption in multi-amp systems |
| Output Drive | ±20 mA @ ±15 V - drives 600 Ω loads directly, eliminating need for external buffers in line-level audio or DAC output stages |
| Operating Temp Range | –40°C to +85°C - qualified for industrial environments including automated test equipment and PLC analog I/O modules |
| Channel Separation | –130 dB @ 1 kHz - prevents measurable crosstalk between adjacent channels in 4-channel data acquisition front-ends |
Pinout & Package
AD8674ARUZ-REEL is packaged in a 14-lead TSSOP (RU-14) with 0.65 mm pitch, 5.00 mm × 4.40 mm body, and exposed pad for thermal enhancement. Pin 1 identifier is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - capable of ±20 mA drive into 600 Ω with <1.2 V headroom from rails |
| 2 | –IN A | Inverting input of Amp A - differential input capacitance 7.5 pF; requires matched trace lengths in high-frequency layouts |
| 3 | +IN A | Non-inverting input of Amp A - common-mode input range extends to rails (±12 V @ ±15 V supply) |
| 4 | V+ | Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from other inputs; shares no internal substrate nodes with Amp A |
| 6 | –IN B | Inverting input of Amp B - same input impedance (3.5 GΩ common-mode, 15 MΩ differential) as Amp A |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to OUT A; independent output stage prevents loading interaction |
| 8 | OUT D | Amplifier D output - pin 8 is not NC; confirmed functional output per Figure 3 top view |
| 9 | –IN D | Inverting input of Amp D - layout symmetry recommended vs. Amp A/B to minimize board-level mismatch |
| 10 | +IN D | Non-inverting input of Amp D - supports single-ended or differential input configurations with matched external resistors |
| 11 | V– | Negative supply rail - must be connected; floating V– causes undefined operation and potential latch-up |
| 12 | +IN C | Non-inverting input of Amp C - pin 12 is active; not a no-connect per datasheet Figure 3 |
| 13 | –IN C | Inverting input of Amp C - validated for use in transimpedance or current-sense configurations |
| 14 | OUT C | Amplifier C output - fully specified for 0.1% settling in 5.1 µs (4 V step, G = 1), supporting fast data acquisition |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed operation with inputs driven 1 V beyond either supply rail - eliminates risk of latch-up in overvoltage transient conditions |
| Capacitive load drive | Stable with >1000 pF loads - removes need for isolation resistors in ADC driver or piezo sensor interfaces |
| Low 1/f noise | 77 nV p-p (0.1 Hz to 10 Hz) - critical for DC-coupled strain gauge and thermopile amplifier applications |
| High CMRR | 120 dB min - rejects common-mode interference in noisy industrial environments without external guarding |
| Unity-gain stable | No external compensation required - simplifies PCB layout and reduces bill-of-materials for follower and buffer circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower bandwidth (1.3 MHz), higher offset (60 µV typ), lower noise (2.8 nV/√Hz same), 0.2 µV/°C drift | Better long-term stability for calibration equipment; insufficient bandwidth for GPS IF filtering | Select OP4177ARUZ when ultra-low drift dominates over speed and noise floor is acceptable |
| ADA4004-4ARUZ | Higher noise (3.9 nV/√Hz), lower bandwidth (12 MHz), higher supply current (4.5 mA/amp), same 14-lead TSSOP | Superior slew rate (12 V/µs) for pulse amplification; less optimal for low-frequency precision sensing | Select ADA4004-4ARUZ when higher speed and robust overload recovery outweigh noise penalty |

FAQ
What is the maximum capacitive load the AD8674ARUZ-REEL can drive stably in unity-gain configuration?
The AD8674ARUZ-REEL is specified to drive capacitive loads up to 1000 pF without instability or phase reversal. For loads exceeding 1000 pF in unity-gain follower applications, external compensation (e.g., series resistor + feedback capacitor) is recommended per Figure 35 in the datasheet. This ensures monotonic step response and avoids ringing in precision sensor interfaces where AD8674ARUZ-REEL is commonly deployed.
Does the AD8674ARUZ-REEL support single-supply operation?
No - the AD8674ARUZ-REEL is designed exclusively for dual-supply operation from ±5 V to ±15 V. Its input common-mode range does not extend to the negative rail under single-supply conditions, and output swing is asymmetric without balanced supplies. For single-supply applications, consider the AD8604 or ADA4661-4 instead of AD8674ARUZ-REEL.
What is the thermal resistance (θJA) of the AD8674ARUZ-REEL in its 14-lead TSSOP package?
The AD8674ARUZ-REEL in the 14-lead TSSOP (RU-14) package has a junction-to-ambient thermal resistance (θJA) of 112°C/W when mounted on a standard 4-layer PCB. This value assumes proper thermal vias under the exposed pad and adequate copper area - critical for maintaining junction temperature below 106°C at full 4.2 mA per amplifier load and +50°C ambient, as verified in the AD8674ARUZ-REEL power dissipation analysis.
How does the AD8674ARUZ-REEL achieve low 1/f noise while maintaining low input bias current?
The AD8674ARUZ-REEL uses a proprietary bipolar input stage with optimized transistor sizing and biasing to minimize both base current (yielding 12 nA max IB) and flicker noise mechanisms. Its 77 nV p-p (0.1 Hz to 10 Hz) noise is achieved without resorting to chopper stabilization - preserving bandwidth and avoiding switching artifacts that would degrade GPS or audio performance where AD8674ARUZ-REEL is applied.
Is the AD8674ARUZ-REEL pin-compatible with other quad op amps in 14-lead TSSOP packages?
No - the AD8674ARUZ-REEL has a unique pinout (per Figure 3) with V+ on pin 4 and V– on pin 11, differing from industry-standard arrangements like the OP4177 or ADA4004-4. Direct replacement requires PCB layout revision. Always verify pin mapping using the AD8674ARUZ-REEL datasheet before substitution, as incorrect routing may damage the device or system.
