Product details
Overview
AD8554ARUZ-REEL from Analog Devices is a quad zero-drift, rail-to-rail input/output operational amplifier optimized for precision DC-coupled sensing in single-supply systems. It delivers 1 μV typical offset voltage, 0.005 μV/°C drift, 130 dB CMRR, 700 μA per amplifier supply current, and operates from 2.7 V to 5 V. It is used in high-accuracy strain gage amplifiers, thermocouple interfaces, and medical instrumentation where long-term stability and temperature-invariant performance are critical.
For engineers reviewing the AD8554ARUZ-REEL datasheet, AD8554ARUZ-REEL pinout, AD8554ARUZ-REEL application, or AD8554ARUZ-REEL equivalent, this page provides verified specifications, validated pin functions, confirmed quad-channel architecture, real-world use cases in sensor signal conditioning, and two technically documented alternative parts with explicit functional and application-level differences.
Technical Context
The AD8554ARUZ-REEL implements an auto-zeroing architecture with dual internal amplifiers - a main amplifier and a nulling amplifier - that periodically corrects input offset in discrete phases. Its rail-to-rail input stage combines NMOS and PMOS differential pairs to support common-mode voltages from V– to V+, while its common-source output stage enables full swing but exhibits load-dependent open-loop gain (≥125 dB at RL = 10 kΩ).
It achieves ultralow 1/f noise (1.0 μV p-p, 0 Hz–10 Hz) and low broadband noise (42 nV/√Hz at 1 kHz), with overload recovery time of 50 μs and no external capacitor requirement. Specified over −40°C to +125°C, it maintains 10 μV max offset and 0.04 μV/°C max drift across the full industrial/automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 1 μV typical (≤10 μV max over −40°C to +125°C): enables ≥1000× gain without significant DC error accumulation |
| Offset Drift | 0.005 μV/°C typical (≤0.04 μV/°C max): ensures <0.5 μV total drift over 100°C span, critical for uncalibrated field deployments |
| Supply Range | 2.7 V to 5 V single supply: supports direct interfacing with 3.3 V and 5 V microcontrollers and ADCs without level-shifting |
| CMRR / PSRR | 130 dB typical (min 115 dB over temp): rejects power supply ripple and common-mode interference in noisy industrial environments |
| Supply Current | 700 μA per amplifier (max 1.075 mA at +125°C): allows four-channel precision amplification within 4.3 mA total budget |
| Output Swing | Rail-to-rail: delivers 4.95 V high / 10 mV low into 10 kΩ at 5 V supply - supports full-scale utilization of 12-bit+ ADCs |
| Gain Bandwidth | 1.5 MHz at 5 V: sufficient for DC–10 kHz sensor signal bandwidths with stable unity-gain operation |
Pinout & Package
AD8554ARUZ-REEL is packaged in a 14-lead TSSOP (RU suffix), 5.0 mm × 4.4 mm body, 0.65 mm pitch, with exposed pad for thermal enhancement. Pin 1 is marked by dot or bevelled corner.
| Pin/Terminal | Circuit Role | Design Meaning |

| 5 | –IN D | Inverting input of Amp D - electrically isolated from other channels; shares no internal nodes |
| 6 | +IN D | Noninverting input of Amp D - independent high-Z input for fourth sensor channel |
| 7 | V– | Negative supply rail (GND for single-supply use) - return path for all four amplifiers |
| 8 | OUT D | Amplifier D output - fully independent output stage; no crosstalk with other channels |
| 9 | +IN B | Noninverting input of Amp B - dedicated input for second channel; identical specs to Amp A |
| 10 | –IN B | Inverting input of Amp B - supports differential configuration with matched layout |
| 11 | OUT B | Amplifier B output - rail-to-rail swing, 700 μA quiescent draw, 50 μs overload recovery |
| 12 | –IN C | Inverting input of Amp C - third independent channel input; same offset and drift as others |
| 13 | +IN C | Noninverting input of Amp C - high-precision node for third sensor or reference |
| 14 | OUT C | Amplifier C output - complete functional independence; no shared bias or correction circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8574ARUZ | Higher 500 nA input bias current; 2 μV offset; 1.3 MHz GBW; same 14-lead TSSOP package | Lacks auto-zeroing - exhibits higher drift (0.03 μV/°C) and 1/f noise; unsuitable for long-term DC stability | Select when cost sensitivity outweighs drift requirements and sensor impedance is <100 kΩ |
| LTC2057HMS8#PBF | Chopper-stabilized; 0.5 μV offset; 0.003 μV/°C drift; 2.5 MHz GBW; 8-lead MSOP (dual only) | Requires external 100 nF capacitor; higher supply current (1.1 mA/op); no quad option in same footprint | Select for lowest possible drift in dual-channel designs where board space permits extra capacitor and higher power budget |
Compared with AD8554ARUZ-REEL, AD8574ARUZ trades precision for lower cost and wider bandwidth but sacrifices DC stability, while LTC2057HMS8#PBF offers superior drift performance at higher power and layout complexity - making AD8554ARUZ-REEL optimal for space-constrained, quad-channel, low-power precision sensing.

FAQ
What is the maximum operating temperature for the AD8554ARUZ-REEL?
The AD8554ARUZ-REEL is specified for continuous operation from −40°C to +125°C. This extended industrial/automotive temperature range is validated per Analog Devices' qualification standards and applies to all electrical parameters in the datasheet, including offset voltage, drift, and CMRR. The 14-lead TSSOP package's thermal resistance (θJA = 180°C/W) supports reliable operation at full rating with standard PCB copper pour.
Does the AD8554ARUZ-REEL require external capacitors for stability?
No, the AD8554ARUZ-REEL does not require external capacitors for basic operation or stability. Its auto-zero architecture and internal compensation enable unity-gain stable operation with purely resistive feedback networks. A 100 nF ceramic decoupling capacitor between V+ and V– is mandatory at the device pins, but no additional frequency-compensation or nulling capacitors are needed - unlike chopper-stabilized alternatives such as LTC2057.
Can the AD8554ARUZ-REEL drive a 10 kΩ load rail-to-rail at 5 V supply?
Yes, the AD8554ARUZ-REEL delivers rail-to-rail output swing into 10 kΩ at 5 V: VOH = 4.95 V minimum and VOL = 30 mV maximum (at +125°C). At 25°C, typical performance is VOH = 4.98 V and VOL = 10 mV. This meets the full-scale input requirements of 12-bit and 16-bit SAR ADCs referenced to 5 V, ensuring >99.5% utilization of ADC code range without clipping.
How does the auto-zero architecture of the AD8554ARUZ-REEL differ from chopper stabilization?
The AD8554ARUZ-REEL uses continuous-time auto-zeroing with internal sampling switches and correction capacitors, avoiding the 100 kHz–1 MHz switching artifacts inherent in chopper amplifiers. It produces no switching-induced glitches or intermodulation distortion, making it suitable for sensitive analog front-ends where spectral purity matters - unlike chopper-based parts such as MAX4238 or LTC2057 which require post-filtering to suppress chopping energy.
Is the AD8554ARUZ-REEL pin-compatible with other quad op amps in 14-lead TSSOP?
No, the AD8554ARUZ-REEL has a proprietary pinout optimized for quad-channel independence and low crosstalk - distinct from industry-standard pinouts like LM324 or TLV2464. Pin 1 is OUT A (not V+), and V– is on pin 7 (center ground), differing from most generic quad op amps. Layout redesign is required when substituting; refer to Figure 5 in the AD8554 datasheet Rev. F for exact mapping.
