Product details
Overview
MC1558N from STMicroelectronics is a high-performance, dual operational amplifier in an 8-pin DIP package, featuring ±22 V supply voltage tolerance, 200 V/mV large-signal voltage gain, and 0.2–0.8 V/µs slew rate. It operates across 0 °C to 70 °C and delivers ±12 V input common-mode range and 120 dB channel separation-used in precision analog summing and active filtering circuits.
For engineers reviewing the MC1558N datasheet, MC1558N pinout, MC1558N application, or MC1558N equivalent, key selection criteria include input offset voltage (1–6 mV), output short-circuit current (10–35 mA), full-power bandwidth (14 kHz), and SO8/DIP8 package compatibility for through-hole prototyping and industrial signal conditioning.
Technical Context
The MC1558N integrates two independent high-gain op-amps on a single monolithic die with no internal frequency compensation required, enabling stable unity-gain operation without external capacitors. Its differential input stage supports ±30 V differential input voltage and exhibits 70–90 dB common-mode rejection over temperature.
It features short-circuit protected outputs capable of sourcing up to 35 mA continuously, and maintains 65° phase margin and 11 dB gain margin under unity-gain conditions with 100 pF load capacitance-ensuring robust stability in feedback configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±22 V - supports wide-rail analog systems including ±15 V industrial supplies |
| Large-Signal Gain | 50–200 V/mV - enables high-precision closed-loop gain accuracy in integrators and transimpedance amps |
| Slew Rate | 0.2–0.8 V/µs - limits maximum undistorted sinusoidal output frequency to ~14 kHz at ±10 V swing |
| Input Offset Voltage | 1–6 mV - determines DC error budget in precision summing and instrumentation amplifier front-ends |
| Channel Separation | 120 dB - prevents crosstalk between dual channels in stereo audio or multi-channel sensor interfaces |
| Common-Mode Range | ±12 V - allows rail-to-rail input operation with ±15 V supplies, simplifying level-shifting design |
| Output Short-Circuit Current | 10–35 mA - provides inherent protection during overload without external current-limiting resistors |
Pinout & Package
MC1558N uses an 8-pin Dual In-line Package (DIP) with standard through-hole mounting. Pin 1 is top-left corner marker; pins are numbered counter-clockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | Accepts negative feedback or signal inversion path for first op-amp |
| 2 | Non-Inverting Input (Amp A) | Reference or positive signal input for first op-amp; sets common-mode operating point |
| 3 | Output (Amp A) | Delivers amplified, buffered output with 75 Ω source impedance and ±14 V swing capability |
| 4 | V− Supply | Negative rail connection; must be decoupled locally to minimize noise coupling |
| 5 | Non-Inverting Input (Amp B) | Independent reference input for second op-amp; electrically isolated from Amp A inputs |
| 6 | Inverting Input (Amp B) | Second op-amp's feedback node; supports independent gain configuration |
| 7 | Output (Amp B) | Second independent output; 120 dB isolation ensures minimal inter-channel interference |
| 8 | V+ Supply | Positive rail connection; shared supply enables compact dual-amplifier implementation |
Key Features
| Feature | Design Value |
|---|---|
| No internal frequency compensation | Enables stable unity-gain operation without external capacitor; reduces BOM count in basic amplifiers |
| High channel separation (120 dB) | Minimizes signal bleed between dual paths-critical in dual-tone generators and stereo preamps |
| ±30 V differential input rating | Prevents latch-up when input transients exceed rails-enhances reliability in noisy industrial environments |
| Short-circuit protected outputs | Allows direct connection to low-impedance loads (e.g., 600 Ω audio lines) without external current limiting |
| Wide common-mode input range (±12 V) | Supports direct interfacing with bipolar sensors and DAC outputs without level-shifting circuitry |
Applications
| Audio Signal Mixing | Precision Sensor Summation |
|---|---|
Use Scenario: Combining multiple line-level audio sources into a mono or stereo bus with minimal crosstalk. IC Role / Device Role / Timing Role: Dual op-amp configured as inverting summing junctions-one per channel-with independent gain control. Use Value: 120 dB channel separation preserves stereo imaging integrity; ±12 V common-mode range accommodates unbalanced consumer audio signals. | Use Scenario: Aggregating outputs from four strain-gauge bridges in a load-cell array for total weight calculation. IC Role / Device Role / Timing Role: Two independent non-inverting summing amplifiers, each combining two bridge outputs before ADC sampling. Use Value: Low 1–6 mV input offset minimizes zero-error accumulation; ±22 V supply headroom handles bridge excitation variations. |
| Active Low-Pass Filtering | Function Generator Core |
Use Scenario: Building a 2-pole Sallen-Key filter for anti-aliasing prior to 100 kSPS data acquisition. IC Role / Device Role / Timing Role: First op-amp as unity-gain buffer driving RC network; second as gain stage with feedback stabilization. Use Value: 1 MHz unity-gain bandwidth and 65° phase margin ensure predictable roll-off without peaking at cutoff. | Use Scenario: Generating triangle and square waveforms via integrator-comparator loop in benchtop test equipment. IC Role / Device Role / Timing Role: One op-amp as integrator (linear ramp), second as comparator (threshold detection and reset). Use Value: 0.2–0.8 V/µs slew rate defines max triangle frequency (~14 kHz); no external compensation simplifies loop tuning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358N | Single-supply only (3–32 V), lower gain (100 V/mV typ), higher input offset (2–7 mV) | Optimized for 0–5 V microcontroller interfaces; lacks dual-rail support | Select when cost-sensitive single-supply designs dominate and ±15 V rails are unavailable |
| TL082CP | JFET-input (50 pA bias current), higher slew rate (13 V/µs), requires external compensation | Better for high-Z sensor buffering and wideband AC coupling; less tolerant of input overvoltage | Choose for low-noise, high-input-impedance applications where ±22 V supply and latch-up immunity are secondary |
Compared with LM358N and TL082CP, MC1558N uniquely balances rail-to-rail input operation, ±22 V tolerance, and uncompensated stability-making it optimal for legacy industrial analog systems requiring robustness over bandwidth.

FAQ
Is MC1558N pin-compatible with MC1458?
Yes, MC1558N is a direct functional and pin-for-pin replacement for MC1458 in DIP8 packaging. Both share identical pinout, electrical specifications, and thermal characteristics. The MC1558N designation reflects ST's updated ordering nomenclature post-2016 revision, with no circuit or performance changes from the original MC1458DT lineage.
Can MC1558N operate from a single +30 V supply?
No. MC1558N is specified only for split-rail operation (e.g., ±15 V). Its input common-mode range extends to ±12 V and absolute maximum supply is ±22 V. Single-supply use violates the common-mode input specification and risks latch-up or undefined output behavior-use LM358N or TL072 instead for single-rail designs.
What is the recommended bypass capacitor for MC1558N?
ST recommends 100 nF ceramic capacitors placed within 5 mm of pins 4 (V−) and 8 (V+) to ground. These suppress high-frequency supply noise and prevent oscillation due to parasitic inductance in breadboard or PCB traces. For high-current applications, add a 10 µF tantalum capacitor in parallel to handle low-frequency ripple.
Does MC1558N require external compensation components?
No. MC1558N is internally compensated for unity-gain stability and does not require external capacitors. This is confirmed in Section 1 of the datasheet schematic and Table 2 AC parameters. Adding compensation may degrade bandwidth and increase settling time unnecessarily-only consider external networks if driving heavy capacitive loads (>100 pF) directly.
