Product details
Overview
MC4558IDT from STMicroelectronics is a dual bipolar operational amplifier optimized for wide-bandwidth, low-noise analog signal conditioning in industrial and instrumentation systems. It delivers 5.5 MHz gain bandwidth product, 2.2 V/µs slew rate, ±12 V output swing into 10 kΩ, and operates across –40 °C to +105 °C with ±2 V to ±20 V supply range.
For engineers reviewing the MC4558IDT datasheet, MC4558IDT pinout, MC4558IDT application, or MC4558IDT equivalent, key selection criteria include unity-gain stability, channel-to-channel gain/phase matching, short-circuit protection, input offset voltage ≤6 mV, and SO-8 package compatibility with legacy MC1458/LM358 footprints.
Technical Context
The MC4558IDT integrates two internally compensated high-slew-rate op-amps on a single die, sharing thermal and process-matched characteristics. Its bipolar input stage provides low input bias current (max 500 nA), moderate input impedance (0.3–2 MΩ), and 120 dB channel separation-enabling precision dual-path signal processing without crosstalk-induced distortion.
Designed for unity-gain stable operation, it achieves 5.5 MHz GBP at 100 kHz test frequency and maintains ≥70 dB CMRR and SVR across full temperature range. The device uses robust short-circuit protected output stages capable of sourcing/sinking up to 40 mA continuously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz at 100 kHz - enables stable closed-loop gain ≥10 at 500 kHz |
| Slew Rate | 2.2 V/µs - supports clean 10 Vpp output at ≥100 kHz without slewing distortion |
| Input Offset Voltage | ≤6 mV - ensures ≤60 µV error in 10× gain sensor amplification |
| Output Swing | ±12 V into 10 kΩ - delivers rail-to-rail usable dynamic range with ±15 V supplies |
| Supply Voltage Range | ±2 V to ±20 V - accommodates low-voltage portable and high-dynamic-range industrial rails |
| Operating Temperature | –40 °C to +105 °C - qualified for under-hood automotive and factory-floor environments |
| Channel Separation | 120 dB - prevents inter-channel coupling in dual-filter or differential driver topologies |
Pinout & Package
MC4558IDT is housed in an SO-8 plastic micropackage (ECOPACK® compliant), measuring 4.9 mm × 6.0 mm × 1.75 mm, with 1.27 mm lead pitch and gull-wing terminations suitable for automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | Non-inverting Input (Amplifier A) | Reference input for single-ended or differential sensing; matched to Pin 6 |
| 3 | Output (Amplifier A) | Class-AB output stage with short-circuit protection; drives loads ≥2 kΩ |
| 4 | VCC– | Negative supply rail connection; must be decoupled within 10 mm of Pin 4 |
| 5 | Inverting Input (Amplifier B) | Electrically identical to Pin 1; enables matched dual-channel configurations |
| 6 | Non-inverting Input (Amplifier B) | Electrically identical to Pin 2; supports independent or cascaded amplifier use |
| 7 | Output (Amplifier B) | Independent output stage; no internal cross-coupling with Pin 3 |
| 8 | VCC+ | Positive supply rail connection; requires local 100 nF ceramic decoupling |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DT | Lower GBP (1 MHz), slower slew rate (0.6 V/µs), wider Vio (7 mV max), narrower temp range (0–70 °C) | Cost-sensitive consumer-grade applications where bandwidth and precision are secondary | Select when budget constraints outweigh performance requirements and ambient temperature stays below 70 °C |
| TL072CDT | JFET input (Iib < 200 pA), higher GBP (3 MHz), no short-circuit protection, higher Vio (10 mV max) | High-input-impedance circuits like photodiode transimpedance amps or high-Z sensor buffers | Select when ultra-low input bias current is mandatory and short-circuit risk is mitigated externally |
Compared with LM358DT and TL072CDT, MC4558IDT uniquely balances wide bandwidth, robust protection, and extended temperature operation - making it optimal for industrial signal chains requiring reliability and precision without JFET-level input impedance.

FAQ
Is MC4558IDT unity-gain stable?
Yes, MC4558IDT is internally compensated for unity-gain stability. It maintains phase margin >45° and exhibits no peaking or oscillation when configured as a voltage follower or in any closed-loop gain ≥1 configuration, verified per Figure 4 (open-loop frequency response) and Table 4 test conditions.
What is the maximum load capacitance MC4558IDT can drive without instability?
MC4558IDT is characterized with 100 pF load capacitance in slew rate and rise time tests. Driving >200 pF directly may degrade phase margin; for capacitive loads exceeding 100 pF, a series isolation resistor (≥10 Ω) between output and load is recommended to maintain stability per standard op-amp layout practice.
Does MC4558IDT support single-supply operation?
No, MC4558IDT is a dual-supply bipolar op-amp requiring symmetric or asymmetric split rails (e.g., ±5 V, ±12 V, or +15 V/–5 V). Its input common-mode range extends to ±12 V and output swing is centered around ground - it lacks rail-to-rail input or output capability required for true single-supply use.
How does MC4558IDT differ from MC4558CDT?
MC4558IDT is rated for –40 °C to +105 °C operation and specified with tighter electrical limits over that full range, while MC4558CDT is qualified only from 0 °C to +70 °C. Both share identical SO-8 packaging, pinout, and electrical specs at 25 °C, but I-grade parts undergo extended temperature screening and parameter validation.
