Product details
Overview
MC4558CPT from STMicroelectronics is a dual bipolar operational amplifier in TSSOP-8 package, featuring 5.5 MHz gain-bandwidth product, ±12 V input common-mode range, 2.2 V/µs slew rate, and 77 dB supply voltage rejection at ±15 V supply. It serves as a general-purpose signal conditioning amplifier in analog front-ends for industrial sensors and audio preamplifiers.
For engineers reviewing the MC4558CPT datasheet, MC4558CPT pinout, MC4558CPT application, or MC4558CPT equivalent, key selection criteria include unity-gain stability, channel-to-channel gain/phase matching, short-circuit protection, low input bias current (max 500 nA), and compatibility with legacy MC1458/LM358 layouts.
Technical Context
The MC4558CPT integrates two internally compensated op-amps on a single die using bipolar process technology, enabling matched AC performance (gain bandwidth, phase margin) and DC parameters (input offset voltage ≤6 mV, input offset current ≤200 nA). Its architecture supports rail-to-rail output swing under light loads but does not include rail-to-rail input capability.
Designed for stable operation at unity gain, it delivers 120 dB channel separation and 0.008% THD at 1 kHz, making it suitable for precision DC-coupled amplification and low-distortion AC signal paths where thermal drift and inter-channel crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 5.5 MHz - enables stable closed-loop operation up to ~500 kHz with gain ≥11 |
| Slew rate | 2.2 V/µs - supports 10 Vpp output at ~350 kHz without slewing distortion |
| Input offset voltage | 6 mV max - limits DC error to <±6 mV in unity-gain buffer configurations |
| Supply voltage range | ±2 V to ±20 V - allows operation from low-voltage ±3 V to high-voltage ±15 V rails |
| Channel separation | 120 dB - ensures minimal crosstalk between dual amplifiers in shared substrate |
| Output short-circuit current | 40 mA max - provides robust fault tolerance without external current limiting |
| Common-mode rejection | 90 dB max - rejects power supply ripple and shared-noise coupling in differential sensing |
Pinout & Package
TSSOP-8 (Thin Shrink Small Outline Package), 3.0 mm × 4.4 mm body, 0.65 mm pitch, lead-free and RoHS-compliant per ECOPACK® specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts feedback network connection; referenced to internal bias point |
| 2 | Non-inverting input (Amplifier A) | DC-coupled signal entry point; common-mode range extends to ±12 V |
| 3 | Output (Amplifier A) | Capable of ±13 V swing into 2 kΩ load; short-circuit protected |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally |
| 5 | Non-inverting input (Amplifier B) | Independent input node; matched offset and bias characteristics vs. Pin 2 |
| 6 | Inverting input (Amplifier B) | Feedback node for second amplifier; electrically isolated from Pin 1 |
| 7 | Output (Amplifier B) | Identical drive capability and protection as Pin 3 |
| 8 | VCC+ | Positive supply rail connection; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Internally compensated | Unity-gain stable without external compensation components |
| Short-circuit protection | Continuous safe operation with output shorted to either rail |
| Gain and phase match | Ensures consistent frequency response and timing alignment across both channels |
| Low power consumption | 4.5 mA typical total supply current enables use in space-constrained, thermally sensitive designs |
| Pin-to-pin compatible | Direct replacement for MC1458 and LM358 in existing PCB layouts |
Applications
| Industrial Sensor Signal Conditioning | Audio Pre-amplification |
|---|---|
Use Scenario: Amplifying low-level mV-range outputs from RTDs, strain gauges, or thermocouples in PLC I/O modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled instrumentation amplifier stage with matched gain and offset tracking. Use Value: 120 dB channel separation prevents cross-talk between sensor channels; ±12 V input common-mode range accommodates grounded-sensor configurations. | Use Scenario: First-stage gain block in microphone preamplifiers and line-level audio mixers.

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), no short-circuit protection, wider input offset (7 mV max) | Limited to low-frequency, non-critical DC amplification | Select when cost sensitivity outweighs bandwidth and protection requirements |
| TL072CDT | JFET-input (lower Iib = 20 pA), higher GBP (3 MHz), no internal compensation | Requires external compensation; unsuitable for unity-gain buffers without modification | Choose for high-impedance sensor interfaces where input bias current dominates error budget |
Compared with LM358DT and TL072CDT, the MC4558CPT uniquely balances unity-gain stability, short-circuit resilience, and 5.5 MHz bandwidth-making it optimal for industrial analog signal chains requiring reliability and layout compatibility without design iteration.

FAQ
Is MC4558CPT unity-gain stable?
Yes. The MC4558CPT is internally compensated for unity-gain stability, as confirmed by its guaranteed phase margin (>60°) and open-loop frequency response data in the official datasheet. No external compensation components are required for stable operation at gain = 1, making it suitable for buffer and follower configurations without risk of oscillation.
What is the maximum operating temperature for MC4558CPT?
The MC4558CPT is rated for 0 °C to +70 °C ambient operating temperature, consistent with its "C" grade designation. This differs from the "I" grade (MC4558ID/IDT), which supports -40 °C to +105 °C. Thermal derating applies above 70 °C ambient due to its 120 °C/W junction-to-ambient thermal resistance in TSSOP-8.
Does MC4558CPT support rail-to-rail input or output?
No. The MC4558CPT features a bipolar input stage with ±12 V input common-mode range (at ±15 V supply), meaning inputs must remain ≥3 V away from either rail. Output swing is ±13 V into 2 kΩ, so it does not reach the supply rails. It is not a rail-to-rail device-designs requiring full-rail operation require alternative op-amps such as TS912 or MCP6022.
Can MC4558CPT replace LM358 in existing designs?
Yes-MC4558CPT is explicitly pin-to-pin compatible with LM358 and MC1458 per ST's datasheet. It offers identical pinout, supply voltage range, and output drive capability, while improving bandwidth (5.5 MHz vs. 1 MHz), slew rate (2.2 V/µs vs. 0.6 V/µs), and channel matching. No layout changes are needed for drop-in replacement in SO-8 or TSSOP-8 footprints.
