Product details
Overview
OP284TRZ-EP-R7 from Analog Devices is a dual, rail-to-rail input/output (RRIO), precision operational amplifier optimized for single-supply operation across 5 V to 36 V (±2.5 V to ±18 V). It delivers 4.25 MHz gain bandwidth, 4.0 V/µs slew rate, and 100 µV max offset voltage at 25°C - enabling high-fidelity signal conditioning in battery-powered instrumentation and DAC output amplification.
For engineers reviewing the OP284TRZ-EP-R7 datasheet, OP284TRZ-EP-R7 pinout, OP284TRZ-EP-R7 application, or OP284TRZ-EP-R7 equivalent, key selection criteria include guaranteed −55°C to +125°C military-grade temperature operation, low 3.9 nV/√Hz voltage noise, unity-gain stability, and SOIC_N (R-8) package compatibility with space-constrained defense and aerospace systems.
Technical Context
The OP284TRZ-EP-R7 integrates two independent precision op-amps sharing a common extended temperature range and enhanced product baseline. Its RRIO architecture supports full-scale signal swing in single-supply configurations, eliminating level-shifting circuitry in multistage filters and transducer interfaces.
Designed for high-reliability applications, it features controlled manufacturing (single fab/assembly/test site), AQEC-compliant qualification, and documented thermal resistance (θJA = 158°C/W, θJC = 43°C/W) for SOIC_N packaging - critical for thermal management in sealed or convection-limited enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4.25 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥ 40, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 4.0 V/µs - supports 10 V p-p output at ≥35 kHz without distortion, critical for fast-settling DAC buffers. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.002% gain error in 5 V full-scale precision measurement paths. |
| Supply Range | 5 V to 36 V (or ±2.5 V to ±18 V) - accommodates wide-input industrial power rails and legacy ±15 V systems. |
| Operating Temperature | −55°C to +125°C - qualified per AQEC standard for deployment in avionics, downhole tools, and satellite subsystems. |
| Voltage Noise Density | 3.9 nV/√Hz at 1 kHz - preserves SNR > 100 dB in 20 kHz audio and sensor front-end applications. |
| Common-Mode Rejection | 86 dB (min, −55°C to +125°C) - maintains accuracy when amplifying low-level signals in noisy power supply environments. |
Pinout & Package
OP284TRZ-EP-R7 is housed in an 8-lead SOIC_N (narrow-body) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions. The package supports reflow soldering and meets RoHS compliance (Z suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to ±6.5 mA (5 V supply) or ±10 mA (±15 V supply) with rail-to-rail swing. |
| 2 | −IN A | Inverting input of Channel A - accepts common-mode voltages from V− to V+, enabling true single-supply signal acquisition. |
| 3 | +IN A | Noninverting input of Channel A - matched bias current (≤450 nA) minimizes offset drift in high-impedance sensor interfaces. |
| 4 | V− | Negative supply rail - connects to ground (single-supply) or negative rail (dual-supply); supports −18 V minimum rating. |
| 5 | +IN B | Noninverting input of Channel B - electrically isolated from Channel A; channel separation >100 dB at 1 kHz ensures crosstalk-free dual-channel operation. |
| 6 | −IN B | Inverting input of Channel B - identical electrical specs to Pin 2; enables independent configuration of second amplifier stage. |
| 7 | OUT B | Amplifier B output - functionally identical to Pin 1; allows dual-path signal processing without external components. |
| 8 | V+ | Positive supply rail - accepts up to +18 V; PSRR of 90 dB (−55°C to +125°C) rejects supply ripple in unregulated systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full dynamic range utilization in 3.3 V, 5 V, or ±15 V systems - eliminates clipping in ADC input buffers and DAC output stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP284ESZ-REEL | Commercial-grade version (−40°C to +85°C), same SOIC_N package and electrical specs except temperature range and AQEC qualification. | Lacks military temperature screening and controlled baseline - unsuitable for aerospace or defense deployments requiring long-term reliability under thermal cycling. | Select OP284ESZ-REEL only for cost-sensitive commercial designs where extended temperature operation is not required. |
| ADA4077-2ARZ-R7 | Lower input bias current (0.3 nA typ vs. 450 nA), lower offset drift (0.1 µV/°C vs. 2.0 µV/°C), but narrower GBW (3.5 MHz) and slower slew rate (0.8 V/µs). | Better for ultra-high-impedance pH or photodiode sensors; less suitable for fast DAC buffering or wideband filtering due to bandwidth limitations. | Choose ADA4077-2ARZ-R7 when femtoampere-level input leakage dominates design constraints over speed. |
Compared with OP284TRZ-EP-R7, OP284ESZ-REEL sacrifices military-grade reliability for cost, while ADA4077-2ARZ-R7 trades bandwidth and slew rate for ultra-low input current - making OP284TRZ-EP-R7 the optimal balance of speed, precision, and ruggedness for defense-critical signal chains.

FAQ
What is the maximum supply voltage rating for OP284TRZ-EP-R7?
The OP284TRZ-EP-R7 has an absolute maximum supply voltage rating of ±18 V (or 36 V total for single-supply operation). Operation beyond this limit risks permanent damage. Per the datasheet, the recommended operating range is 5 V to 36 V (or ±2.5 V to ±18 V), with full specifications guaranteed across −55°C to +125°C within these bounds. Always observe the differential input voltage limit of ±0.6 V.
Does OP284TRZ-EP-R7 support rail-to-rail input and output simultaneously?
Yes, OP284TRZ-EP-R7 supports true rail-to-rail input and output (RRIO) operation. Its input common-mode range extends from V− to V+, and its output swings within 125 mV of V− and 200 mV of V+ (at 1 mA load, 5 V supply). This capability enables full-scale signal handling in single-supply systems without external level-shifting circuitry - a key feature confirmed in the General Description and Electrical Characteristics tables.
Is OP284TRZ-EP-R7 pin-compatible with standard SOIC-8 op-amps?
OP284TRZ-EP-R7 uses the industry-standard 8-lead SOIC_N (narrow-body) package per JEDEC MS-012-AA, matching footprint and pinout of generic SOIC-8 op-amps. However, pin compatibility does not guarantee functional interchangeability - its enhanced temperature range, AQEC qualification, and specific electrical performance (e.g., 4.25 MHz GBW, 4.0 V/µs slew rate) differ from commercial-grade equivalents. Always verify layout and thermal design against the OP284TRZ-EP-R7's θJA = 158°C/W.
What is the typical input offset voltage drift of OP284TRZ-EP-R7 over temperature?
The OP284TRZ-EP-R7 exhibits an input offset voltage drift of 0.2 µV/°C (typical) to 2.0 µV/°C (maximum) across −55°C to +125°C. This parameter is explicitly specified in Tables 1 and 2 of the datasheet under "Offset Voltage Drift ΔVOS/ΔT". Such low drift ensures minimal gain error accumulation in precision DC-coupled applications like strain gauge amplifiers operating across extreme environmental conditions.
Can OP284TRZ-EP-R7 drive capacitive loads without instability?
OP284TRZ-EP-R7 is unity-gain stable but exhibits increasing overshoot with capacitive loads: Figure 23 shows ≤20% overshoot at 100 pF and ≤80% at 1000 pF (AVCL = 1, ±2.5 V supply). For loads >100 pF, isolation resistors (e.g., 10–100 Ω in series with output) or feedback capacitor compensation are recommended. The device is not optimized for direct driving of long cables or large capacitive DAC reference nodes without external stabilization.
