Product details
Overview
ISL28213FUZ from Renesas Electronics (formerly Intersil) is a dual-channel, rail-to-rail input/output (RRIO), micropower operational amplifier optimized for precision low-power signal conditioning in single-supply systems. It delivers 2MHz gain bandwidth, 130µA maximum supply current per channel, 20pA max input bias current, and operates across –40°C to +125°C - enabling use in battery-powered sensor front-ends and industrial process control loops.
For engineers reviewing the ISL28213FUZ datasheet, ISL28213FUZ pinout, ISL28213FUZ application, or ISL28213FUZ equivalent, key selection criteria include its micropower consumption at 1.8V–5.5V supply, rail-to-rail output swing within 15mV of rails, ultra-low input bias current for high-impedance transducer interfacing, and guaranteed operation over extended temperature range without derating.
Technical Context
The ISL28213FUZ employs CMOS input stage architecture with ESD-protected diodes to both rails, enabling robust input voltage tolerance beyond supplies (±0.5V differential, ±1V common-mode overvoltage). Its RRIO topology supports full dynamic range utilization in single-supply configurations down to 1.8V.
Internal compensation ensures unity-gain stability across load capacitances up to 100pF, while the 1V/µs slew rate and 7.5µs settling time to 0.1% support moderate-speed precision applications such as active filtering and current shunt amplification without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - enables direct interface with Li-ion, 3.3V, and 5V logic without level-shifting or LDO overhead. |
| Supply Current per Channel | 90–130µA - allows continuous operation in multi-channel battery-powered systems for >10 years on a CR2032 cell. |
| Gain Bandwidth Product | 2MHz - supports closed-loop gains up to 100 at 20kHz with <1dB flatness, suitable for anti-aliasing and sensor signal conditioning. |
| Input Bias Current | ≤20pA - preserves accuracy in high-Z circuits (e.g., pH electrodes, photodiode transimpedance amps) without significant offset drift. |
| Output Swing (RL = 10kΩ) | Within 15mV of rails - maximizes usable dynamic range in single-supply ADC driver stages, minimizing headroom loss. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor instrumentation environments. |
| Input Offset Voltage | ±4mV (max @ 25°C), ±5mV (max @ 125°C) - enables DC-coupled amplification of mV-level sensor outputs without trimming. |
Pinout & Package
ISL28213FUZ is housed in an 8-lead MSOP package (M8.118A), offering compact footprint (3mm × 3mm) and thermal resistance θJA = 180°C/W for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT_A | Amplifier A output - drives loads directly; rail-to-rail swing supports full-scale ADC input range. |
| 2 | IN−_A | Inverting input for Channel A - high-impedance node requiring guard traces in sensitive analog sections. |
| 3 | IN+_A | Non-inverting input for Channel A - accepts signals from sensors, references, or DACs with minimal loading. |
| 4 | VS− | Negative supply rail - connects to ground in single-supply mode; must be decoupled with 0.1µF ceramic capacitor. |
| 5 | VS+ | Positive supply rail - accepts 1.8–5.5V; internal ESD protection clamps inputs to this rail ±0.5V. |
| 6 | IN−_B | Inverting input for Channel B - electrically isolated from Channel A; requires independent layout routing. |
| 7 | OUT_B | Amplifier B output - independently configurable; supports dual-path signal processing or redundancy. |
| 8 | IN+_B | Non-inverting input for Channel B - enables differential pair configuration or separate sensor channel buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Common-mode range extends 100mV beyond rails; output swings to within 15mV - eliminates need for negative supply in most sensor interfaces. |
| Micropower operation | 130µA max per channel at 25°C - reduces thermal load and extends battery life in portable instrumentation and IoT nodes. |
| No output phase reversal | Immune to polarity inversion when inputs exceed supply rails by up to 1V - prevents latch-up and system faults in transient-prone environments. |
| Low input bias current | 20pA max - minimizes voltage error across high-value feedback resistors (>1MΩ) used in precision integrators and transimpedance amplifiers. |
| Extended temperature range | Specified from –40°C to +125°C - supports deployment in automotive engine control units, industrial PLC I/O modules, and outdoor metering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower RRIO op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550µA/ch), lower GBW (6.4MHz), wider VS range (2.7–6V) | Not rated for 125°C operation; unsuitable for under-hood or high-temp industrial use | Select if higher speed and rail-to-rail output are needed at expense of power and temperature range. |
| OPA2333AIDR | Zero-drift architecture, 17µV max VOS, 17µA/ch supply current, 350kHz GBW | Superior DC precision but limited bandwidth; not ideal for >10kHz active filtering or fast settling | Select for ultra-low offset and drift-critical applications like precision weigh scales where speed is secondary. |
Compared with TLV2462IDR and OPA2333AIDR, the ISL28213FUZ uniquely balances micropower (130µA), extended temperature rating (–40°C to +125°C), and 2MHz bandwidth - making it optimal for cost-sensitive, thermally demanding, battery-operated sensor signal chains requiring moderate speed and robustness.

FAQ
What is the maximum operating junction temperature of the ISL28213FUZ?
The ISL28213FUZ has a maximum operating junction temperature of +125°C, as specified in the Absolute Maximum Ratings table. This limit applies regardless of ambient temperature or package type, and thermal design must ensure TJ does not exceed this value under worst-case power dissipation conditions - particularly when driving heavy loads at elevated supply voltages in the MSOP package (θJA = 180°C/W).
Does the ISL28213FUZ require external compensation for unity-gain stability?
No, the ISL28213FUZ is internally compensated for unity-gain stability. It remains stable with capacitive loads up to 100pF and does not require external compensation components in standard non-inverting or inverting configurations. However, layout best practices - including short traces, local 0.1µF bypass capacitors at VS+ and VS−, and proper grounding - are essential to maintain stability in noisy environments.
Can the ISL28213FUZ operate from a single 1.8V supply?
Yes, the ISL28213FUZ is fully specified to operate from a single 1.8V supply (VS+ = 1.8V, VS− = GND), delivering rail-to-rail input common-mode range (–0.1V to +1.9V) and output swing within 15mV of both rails. This capability enables direct integration with ultra-low-voltage microcontrollers and energy-harvesting systems without additional voltage translation circuitry.
How is unused channel handling specified for the ISL28213FUZ?
For unused channels in the ISL28213FUZ, the datasheet mandates configuring each idle amplifier as a unity-gain buffer: short the output to the inverting input, and tie the non-inverting input to a stable reference (e.g., mid-supply or ground). Leaving inputs floating causes oscillation, increasing total supply current and injecting noise into the active channel - degrading system performance and reliability.
What is the input ESD protection rating for the ISL28213FUZ?
The ISL28213FUZ features integrated ESD protection diodes on all input pins rated to 4000V HBM (Human Body Model) and 350V MM (Machine Model). These diodes clamp input voltages to within one diode drop of VS+ and VS−. For sustained overvoltage conditions exceeding ±0.5V relative to either supply rail, an external series current-limiting resistor is required to keep input current below 20mA, as defined in Absolute Maximum Ratings.
