Product details
Overview
OP282GSZ-REEL from Analog Devices is a dual JFET-input operational amplifier optimized for high-speed, low-power operation in precision signal conditioning circuits. It delivers 9 V/µs slew rate, 4 MHz gain bandwidth, and 250 µA/amplifier supply current, with input common-mode range extending to the positive rail - enabling high-side current sensing in battery-powered instrumentation and portable medical devices.
For engineers reviewing the OP282GSZ-REEL datasheet, OP282GSZ-REEL pinout, OP282GSZ-REEL application, or OP282GSZ-REEL equivalent, key selection criteria include its rail-to-rail input capability (VCM = −11 V to +15 V), ultra-low bias current (≤100 pA), 3 mV max offset voltage, and SOIC_N-8 package compatibility with space-constrained industrial and portable designs.
Technical Context
The OP282GSZ-REEL employs a JFET input stage to achieve sub-100 pA bias current and wide common-mode input range including V+, making it suitable for high-side sensing where input signals approach the positive supply. Its unity-gain stability, 55° phase margin, and 4 MHz GBP support robust closed-loop performance in active filters and integrators without external compensation.
Designed for extended industrial temperature operation (−40°C to +85°C), the device maintains low power consumption (<250 µA/amplifier) while delivering fast settling (1.6 µs to 0.01%) and high open-loop gain (>15 V/mV over temperature), enabling accurate DC-coupled amplification in power-restricted systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 9 V/µs - enables faithful reproduction of fast transients in sensor interfaces and active filters |
| Gain Bandwidth Product | 4 MHz - supports stable unity-gain and moderate-gain configurations up to ~100 kHz | Supply Current per Amplifier | 250 µA max - allows dual-channel operation from coin-cell or low-quiescent power rails |
| Input Offset Voltage | 3 mV max - ensures ≤30 µV error in 10× gain stages without trimming |
| Input Bias Current | 100 pA max - minimizes voltage error across high-impedance sources (e.g., photodiode, pH electrode) |
| Common-Mode Input Range | −11 V to +15 V - permits direct high-side current sensing at +15 V rail without level-shifting |
| Output Voltage Swing | Within 1.5 V of each rail - delivers >27 V p-p swing on ±15 V supplies for full-scale analog processing |
Pinout & Package
OP282GSZ-REEL is housed in an 8-lead narrow-body SOIC (S-Suffix, R-8) package per JEDEC MS-012-AA, with standard pinout and 1.27 mm lead pitch. Thermal resistance θJA = 120°C/W (soldered on 4-layer board).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads ≥10 kΩ with <1.5 V headroom to rails |
| 2 | –IN A | Inverting input - high-impedance JFET node; requires matched trace impedance for noise rejection |
| 3 | +IN A | Non-inverting input - accepts signals up to +15 V (V+), enabling high-side sensing |
| 4 | V– | Negative supply pin - must be decoupled with 0.1 µF ceramic near package |
| 5 | V+ | Positive supply pin - supports ±4.5 V to ±18 V operation; decouple locally |
| 6 | OUT B | Second amplifier output - independent channel for dual-path signal processing |
| 7 | –IN B | Second inverting input - electrically isolated from Channel A; same JFET characteristics |
| 8 | +IN B | Second non-inverting input - identical common-mode range and bias current as Pin 3 |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Higher supply current (1.4 mA/amplifier), lower slew rate (13 V/µs but higher noise), no guaranteed VCM = V+ operation | Not suitable for high-side sensing; better for AC-coupled audio where quiescent power is less critical | Select only when cost is primary constraint and rail-sensing capability is unnecessary |
| AD822ARZ | FET input, rail-to-rail output, 1.8 MHz GBP, 3 V/µs slew rate, 800 µA/amplifier supply current | Superior output swing but slower and higher power - trade-off for precision low-voltage systems | Prefer when RRO and low-voltage operation (±2.5 V) outweigh speed/power requirements |
Compared with TL072CDR and AD822ARZ, OP282GSZ-REEL uniquely balances 4 MHz bandwidth, 9 V/µs slew rate, and <250 µA quiescent current while guaranteeing input operation at V+, making it optimal for high-speed, low-power, high-side sensing where alternatives require design compromises in speed, power, or input range.

FAQ
What is the maximum operating supply voltage for OP282GSZ-REEL?
The OP282GSZ-REEL supports a total supply voltage range of ±4.5 V to ±18 V, meaning the maximum allowable difference between V+ and V– is 36 V. Absolute maximum ratings specify ±18 V on each supply rail, and exceeding this may cause permanent damage. Operation at ±15 V is typical in industrial and test equipment designs using OP282GSZ-REEL.
Does OP282GSZ-REEL support high-side sensing with input voltages equal to V+?
Yes, OP282GSZ-REEL guarantees input common-mode voltage range from −11 V to +15 V, which explicitly includes the positive supply rail (V+). This is confirmed in the datasheet's General Description and Applications Information sections, enabling direct high-side current sensing without external level-shifting circuitry - a key differentiator versus many bipolar-input op amps.
Is OP282GSZ-REEL unity-gain stable, and does it require external compensation?
Yes, OP282GSZ-REEL is unity-gain stable and requires no external compensation components. The datasheet states "unity-gain stable" under Features and confirms 55° phase margin in Electrical Characteristics. This allows straightforward use in voltage followers, non-inverting amplifiers, and active filters without added capacitors or resistors - reducing design risk and PCB area.
What is the typical input bias current of OP282GSZ-REEL at room temperature?
The typical input bias current of OP282GSZ-REEL is 3 pA at 25°C, with a maximum of 100 pA over the full −40°C to +85°C temperature range. This ultra-low value is enabled by its JFET input stage and is critical for interfacing with high-impedance sources such as piezoelectric sensors, pH electrodes, or photodiodes - where leakage would otherwise dominate signal accuracy.
Which package type does OP282GSZ-REEL use, and is it RoHS compliant?
OP282GSZ-REEL uses the 8-lead narrow-body SOIC (S-Suffix, R-8) package per JEDEC MS-012-AA, and the "Z" suffix in the part number indicates RoHS compliance. The ordering guide explicitly lists OP282GSZ-REEL as a RoHS-compliant variant, with lead-free terminations and halogen-free molding compound meeting EU Directive 2011/65/EU.
