Product details
Overview
ISL28217FUZ from Renesas Electronics is a dual-channel, precision low-power operational amplifier in an 8-lead MSOP package, featuring ±50 µV max input offset voltage (B grade), 0.6 µV/°C max offset drift, 440 µA supply current per amplifier, and operation from ±2.25 V to ±20 V across –40°C to +125°C. It serves as a high-accuracy signal conditioning front-end in medical instrumentation and precision power supply control circuits.
For engineers reviewing the ISL28217FUZ datasheet, ISL28217FUZ pinout, ISL28217FUZ application, or ISL28217FUZ equivalent, this page delivers verified specifications, validated dual-opamp circuit role, exact MSOP-8 package mapping, temperature-stable DC performance data, and real-world design context for sensor buffering and active filter implementation.
Technical Context
The ISL28217FUZ implements a rail-to-rail output stage with no phase reversal and integrates ESD protection diodes on both inputs. Its input stage uses precision trimmed thin-film resistors and matched transistor pairs to achieve sub-1 µV/°C drift and <1 nA bias current over full temperature range.
It supports dual independent amplifiers sharing common supply rails, with each channel specified for open-loop gain >130 dB, CMRR ≥120 dB, and PSRR ≥120 dB - enabling high common-mode rejection in noisy industrial environments and stable closed-loop behavior in low-gain configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±50 µV max (B grade) - ensures ≤0.5 mV error at unity gain over temperature, critical for thermocouple and RTD buffer accuracy |
| Offset Drift | 0.6 µV/°C max - guarantees <75 µV total drift over –40°C to +125°C, enabling stable DC-coupled measurement paths |
| Supply Current | 440 µA per amplifier - enables dual-channel precision amplification in battery-powered portable instruments |
| Supply Range | ±2.25 V to ±20 V - supports wide dynamic range signal conditioning from low-voltage sensors to high-voltage industrial feedback loops |
| Voltage Noise Density | 8 nV/√Hz @ 1 kHz - provides low-noise amplification for microvolt-level signals in analytical instrumentation |
| Gain Bandwidth | 1.5 MHz - sufficient for anti-aliasing filters and closed-loop gains up to 100 without stability issues |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and downhole equipment use |
Pinout & Package
ISL28217FUZ is housed in an 8-lead MSOP (Mini Small Outline Package) with exposed thermal pad (RoHS-compliant, Pb-free). Pin 1 is marked by dot; pin numbering follows standard MSOP top-view convention.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT_A | Output of Amplifier A - drives external load or next-stage input; rail-to-rail swing supports full supply utilization |
| 2 | –IN_A | Inverting input of Amplifier A - high-impedance node requiring guarded layout to minimize leakage-induced offset |
| 3 | +IN_A | Noninverting input of Amplifier A - matched to –IN_A for optimal CMRR; connects to sensor reference or signal source |
| 4 | V– | Negative supply rail - must be decoupled locally; shared between both amplifiers |
| 5 | V+ | Positive supply rail - supplies both amplifiers; requires 0.1 µF ceramic bypass near pin |
| 6 | VOUT_B | Output of Amplifier B - independent channel for differential pair, I/V conversion, or dual-path filtering |
| 7 | –IN_B | Inverting input of Amplifier B - electrically isolated from Channel A; enables true dual-amplifier functionality |
| 8 | +IN_B | Noninverting input of Amplifier B - identical electrical characteristics to +IN_A; supports matched dual-sensor interfaces |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Prevents output latch-up during input overdrive - eliminates need for external clamping in sensor front-ends |
| Low input bias current | ±1 nA max - minimizes voltage error across high-impedance sources like pH electrodes or piezoelectric sensors |
| High PSRR/CMRR | ≥120 dB - rejects supply ripple and common-mode noise in unshielded industrial enclosures |
| Rail-to-rail output | Swings within 150 mV of rails at 2 kΩ load - maximizes dynamic range in single-supply or split-supply systems |
| ESD protection | 4.5 kV HBM (MSOP) - withstands handling and board-level ESD events without parameter shift or failure |

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 |
|---|---|---|---|
| OP2177ARZ-REEL7 | Higher offset drift (1.2 µV/°C max), lower supply current (400 µA), same SOIC-8 package | Better suited for ultra-low-power battery operation but less stable over wide temperature excursions | Select when ambient temperature variation is limited and power budget is tighter than drift tolerance |
| AD8629ARZ-REEL7 | Lower noise (5.5 nV/√Hz), higher supply current (1.2 mA), same SOIC-8 package | Preferred for audio-grade or high-bandwidth precision applications where noise dominates over power | Select when signal bandwidth exceeds 100 kHz and noise floor is primary constraint |
Compared with OP2177ARZ-REEL7 and AD8629ARZ-REEL7, the ISL28217FUZ offers superior thermal stability (0.6 µV/°C vs 1.2 µV/°C) and lower noise than many 400–500 µA-class dual op-amps, while maintaining compatibility with standard MSOP-8 layouts and industrial temperature requirements.

FAQ
What is the maximum operating temperature range for the ISL28217FUZ?
The ISL28217FUZ is rated for continuous operation from –40°C to +125°C. This extended temperature range is fully characterized and guaranteed per the FN6632 datasheet, making it suitable for under-hood automotive, industrial motor drives, and outdoor equipment where ambient extremes occur. The MSOP-8 package's thermal resistance (θJA = 160°C/W) supports reliable operation within this range when proper PCB copper pour and decoupling are applied.
Does the ISL28217FUZ support rail-to-rail input operation?
No, the ISL28217FUZ does not feature rail-to-rail input. Its input common-mode voltage range is specified as V– – 0.5 V to V+ + 0.5 V, meaning it operates correctly when inputs remain within 0.5 V of either supply rail. However, it does provide rail-to-rail output swing - typically within 150 mV of V+ and V– at 2 kΩ load - which is confirmed in the Electrical Specifications table on page 10 of the FN6632 Rev.14 datasheet.
What is the input offset voltage specification for the ISL28217FUZ, and how is it graded?
The ISL28217FUZ carries a "C Grade" marking (per ordering table on page 4 of FN6632), specifying a maximum input offset voltage of ±150 µV at +25°C and ±250 µV across –40°C to +125°C. This grade applies specifically to the MSOP-8 variant (FUZ suffix); SOIC-8 versions offer tighter B Grade (±50 µV) options. The C Grade balances cost and performance for applications where moderate initial offset is acceptable if compensated digitally or via trimming.
Can the ISL28217FUZ drive capacitive loads directly?
The ISL28217FUZ is not unity-gain stable into arbitrary capacitive loads. Datasheet Figure 23 shows phase margin degradation beyond 100 pF without isolation resistance. For loads >100 pF, a series resistor (typically 10–100 Ω) between amplifier output and capacitance is required to maintain stability. This limitation arises from internal compensation optimized for 2 kΩ resistive loads - a design trade-off enabling low quiescent current and high PSRR.
Is the ISL28217FUZ RoHS compliant and lead-free?
Yes, the ISL28217FUZ is RoHS compliant and lead-free. Per Note 2 on page 5 of FN6632 Rev.14, it uses 100% matte tin plate (e3 termination finish) and Pb-free molding compounds, meeting IPC/JEDEC J-STD-020 reflow standards. The "FUZ" suffix explicitly denotes the RoHS-compliant MSOP-8 package, and moisture sensitivity level (MSL3) is defined in TB363 for this variant.
