Product details
Overview
MC4558IPT from STMicroelectronics is a dual bipolar operational amplifier in TSSOP-8 package, rated for -40 °C to +105 °C operation, featuring 5.5 MHz gain-bandwidth product, 2.2 V/µs slew rate, ±12 V output swing into 10 kΩ, and 77 dB supply voltage rejection - used in precision instrumentation amplifiers and industrial sensor signal conditioning.
For engineers reviewing the MC4558IPT datasheet, MC4558IPT pinout, MC4558IPT application, or MC4558IPT equivalent, key selection considerations include its bipolar input stage (50–400 nA bias current), channel-to-channel gain/phase matching, internal compensation, short-circuit protection, and compatibility with LM358/MC1458 footprints in space-constrained designs.
Technical Context
The MC4558IPT implements two matched high-slew-rate bipolar op-amps on a single die, each with internally compensated unity-gain stable architecture. Its differential input stage delivers 70–90 dB common-mode rejection and 77–90 dB supply rejection over temperature, supporting rail-to-rail compatible operation with ±2 V to ±20 V dual supplies.
Designed for DC-coupled and wideband AC applications up to 100 kHz, it maintains 0.008% THD at 1 kHz and provides 120 dB channel separation - enabling low-noise, low-crosstalk dual-channel signal processing without external compensation networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 5.5 MHz - supports stable closed-loop gain ≥10 at 500 kHz with minimal phase margin degradation |
| Slew rate | 2.2 V/µs - enables clean 10 Vpp output at 35 kHz without slewing distortion |
| Input offset voltage | 1–6 mV - sets minimum resolvable DC signal level in 12-bit ADC front-ends |
| Supply current per amp | 2.3–6 mA - allows dual-channel operation within 12 mA total at ±15 V for portable analog systems |
| Output voltage swing | ±12 V into 10 kΩ - delivers full-scale dynamic range across standard industrial ±10 V control interfaces |
| Channel separation | 120 dB - prevents crosstalk-induced error in dual-channel data acquisition with shared reference |
| ESD rating (HBM) | 500 V - meets basic handling requirements for non-automotive assembly environments |
Pinout & Package
TSSOP-8 package: 3 mm × 4.4 mm body, 0.65 mm pitch, 1.05 mm max height, lead-free and RoHS-compliant per ECOPACK® specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (AMP1) | Accepts feedback network connection for stable inverting configurations |
| 2 | Non-inverting input (AMP1) | DC-biased node for single-supply sensor interface with resistor divider |
| 3 | Output (AMP1) | Drives 2 kΩ loads to ±10 V or 10 kΩ loads to ±12 V without clipping |
| 4 | VCC− | Negative supply rail - must be decoupled with 100 nF ceramic near pin |
| 5 | Non-inverting input (AMP2) | Independent reference point for second channel; matched to Pin 2 for common-mode tracking |
| 6 | Inverting input (AMP2) | Supports matched gain-setting resistors to preserve inter-channel phase alignment |
| 7 | Output (AMP2) | Provides isolated second channel output with 120 dB isolation from AMP1 |
| 8 | VCC+ | Positive supply rail - requires local 100 nF ceramic + 10 µF bulk capacitance |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated | Unity-gain stable without external compensation capacitors - reduces BOM count and layout sensitivity |
| Short-circuit protection | Continuous safe operation with output shorted to either rail - eliminates need for external current-limiting resistors |
| Gain and phase match | Matched AC response between channels ensures <0.1° phase skew at 100 kHz - critical for dual-channel lock-in amplifiers |
| Low power consumption | 4.5 mA typical total supply current at ±15 V - enables dual op-amp use in thermally constrained enclosures |
| Pin-to-pin compatible | Direct replacement for LM358 and MC1458 in SO-8 and TSSOP-8 footprints - simplifies legacy design upgrades |

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 input offset (2–7 mV), same SO-8 footprint | Not suitable for >100 kHz signal paths or fast-settling applications | Select when cost is primary and bandwidth ≤10 kHz suffices |
| TL072CDT | JFET input (50 pA bias), higher GBP (3 MHz), lower noise (18 nV/√Hz), no short-circuit protection | Requires external current limiting; unsuitable for direct sensor interfacing with high source impedance | Select for high-Z sources like piezoelectric sensors where input bias matters more than robustness |
Compared with LM358DT and TL072CDT, MC4558IPT delivers superior bandwidth and slew rate while retaining bipolar robustness and short-circuit tolerance - making it optimal for industrial dual-channel signal chains demanding both speed and reliability.

FAQ
What is the maximum operating junction temperature for MC4558IPT?
The MC4558IPT has a specified operating free-air temperature range of −40 °C to +105 °C. With a TSSOP-8 thermal resistance (RthJA) of 120 °C/W and maximum power dissipation of 680 mW, its calculated maximum junction temperature under worst-case ambient conditions is 185 °C - well below the absolute maximum rating of 150 °C, confirming safe operation within spec.
Can MC4558IPT operate from a single 5 V supply?
Yes - the MC4558IPT supports single-supply operation down to ±2 V (i.e., +4 V total). When powered from +5 V and ground, configure the inputs with appropriate DC bias (e.g., VCC/2 via resistor divider) and ensure output load does not exceed 10 kΩ to maintain ≥3 V swing. Input common-mode range extends to within 1.5 V of rails.
Does MC4558IPT require external compensation capacitors?
No - the MC4558IPT is internally compensated for unity-gain stability. No external capacitor is needed for stable operation at gains ≥1. This eliminates layout sensitivity and reduces bill-of-materials cost compared to decompensated op-amps like the NE5532.
How does MC4558IPT compare to MC4558CD in terms of performance?
The MC4558IPT and MC4558CD share identical electrical characteristics and pinout. The only difference is temperature grade: MC4558IPT is rated for −40 °C to +105 °C, while MC4558CD is rated for 0 °C to +70 °C. Both use SO-8 packaging, but MC4558IPT specifically denotes the TSSOP-8 variant with industrial-grade qualification.
