Product details
Overview
TJM4558CDT from STMicroelectronics is a high-performance dual bipolar operational amplifier in SO-8 package, featuring 5.5 MHz gain-bandwidth product, ±12 V output swing (RL = 10 kΩ), 2.2 V/µs slew rate, and internal compensation for unity-gain stability-used in precision instrumentation amplifiers and active filter stages.
For engineers reviewing the TJM4558CDT datasheet, TJM4558CDT pinout, TJM4558CDT application, or TJM4558CDT equivalent, key selection criteria include channel separation (120 dB), input offset voltage (1–6 mV), short-circuit protection, pin-to-pin compatibility with LM358/MC1458, and −40°C to +105°C industrial temperature range.
Technical Context
The TJM4558CDT integrates two matched bipolar op-amps on a single die with independent input stages, shared biasing, and common-mode rejection of 70–90 dB. Its 5.5 MHz GBP at 100 kHz and 2.2 V/µs slew rate support stable closed-loop operation up to ~200 kHz with moderate gain.
Internally compensated design eliminates external compensation components; short-circuit protection limits output current to 10–20 mA indefinitely. Input stage uses matched transistor pairs enabling <6 mV Vio and 120 dB channel separation-critical for dual-channel signal conditioning without crosstalk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 5.5 MHz at 100 kHz - enables stable unity-gain operation and supports bandwidth-critical active filters |
| Slew Rate | 2.2 V/µs - supports clean 100 kHz sine output at ±10 V without distortion |
| Input Offset Voltage | 1–6 mV - ensures ≤0.06% error in 10 V full-scale DC-coupled sensor interfaces |
| Channel Separation | 120 dB - prevents crosstalk between dual channels in stereo audio or differential measurement paths |
| Supply Current | 2.3–4.5 mA total - enables dual-opamp functionality within 5 mA system power budget |
| Output Swing | ±12 V (RL = 10 kΩ) - delivers rail-to-rail usable dynamic range with ±15 V supplies |
| Common-Mode Rejection | 70–90 dB - rejects noise in non-inverting configurations with unbalanced source impedances |

IC Role / Device Role / Timing Role: First amp converts current to voltage; second buffers and level-shifts output. Use Value: ±12 V output swing accommodates full 0–10 V range with headroom; −40°C to +105°C rating ensures field reliability. |
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), higher Vio (2–7 mV), no short-circuit protection | Limited to low-frequency (<10 kHz), low-precision applications | Select when cost sensitivity outweighs bandwidth and protection requirements |
| TL072CDT | JFET input (Iib = 30 pA), higher GBP (3 MHz), no internal compensation | Requires external compensation; unsuitable for unity-gain stable designs without modification | Choose for ultra-low input bias current needs where external compensation is acceptable |
Compared with LM358DT and TL072CDT, the TJM4558CDT uniquely combines LM358 pin compatibility, 5.5 MHz GBP, internal compensation, and short-circuit protection-making it optimal for drop-in upgrades in industrial signal chains requiring robustness and bandwidth.

FAQ
Is TJM4558CDT pin-compatible with LM358 in SO-8 footprint?
Yes. TJM4558CDT uses the standard SO-8 package (JEDEC MS-012AC) with identical pinout to LM358DT and MC1458D. Pin 1 is inverting input of Amp 1, Pin 2 is non-inverting input of Amp 1, Pin 3 is output of Amp 1, Pin 4 is VCC−, Pin 5 is VCC+, Pin 6 is output of Amp 2, Pin 7 is inverting input of Amp 2, and Pin 8 is non-inverting input of Amp 2-enabling direct PCB replacement.
What is the maximum safe supply voltage for TJM4558CDT?
The absolute maximum supply voltage is ±22 V per the datasheet. For reliable long-term operation, STMicroelectronics recommends staying within ±15 V. Operation at ±18 V is possible but reduces output swing margin and increases thermal stress; derating is advised above ±15 V, especially at elevated ambient temperatures.
Does TJM4558CDT require external compensation capacitors?
No. The TJM4558CDT is internally compensated for unity-gain stability. It does not require external compensation components in standard inverting or non-inverting configurations. This simplifies layout and improves reliability compared to decompensated op-amps like TL072, which mandate external capacitors for stability at gains <10.
Can TJM4558CDT drive a 600 Ω audio load directly?
No. With a typical output resistance of 75 Ω and ±10 V swing into 2 kΩ, the TJM4558CDT cannot deliver sufficient current into 600 Ω without significant voltage droop or distortion. For 600 Ω loads, use an external buffer stage or select a dedicated audio line driver IC with lower Ro and higher Ios (e.g., TDA2822M).
