Product details
Overview
RC4136N from Texas Instruments is a quad general-purpose operational amplifier electrically similar to the µA741 but without offset null capability, featuring 3 MHz unity-gain bandwidth, ±15 V supply voltage range, and 8 nV/√Hz input noise at 1 kHz - used in industrial signal conditioning, sensor interface, and analog front-end circuits.
For engineers reviewing the RC4136N datasheet, RC4136N pinout, RC4136N application, or RC4136N equivalent, key selection criteria include its 0°C to 70°C temperature rating, PDIP-14 package, low 5–11.3 mA total supply current, short-circuit protection, and absence of external frequency compensation requirements.
Technical Context
The RC4136N integrates four independent op-amps with internally compensated architecture enabling stable unity-gain operation without external components. Its high common-mode input voltage range (±12 V) and latch-up immunity support robust voltage-follower and transimpedance configurations.
Each amplifier exhibits matched gain and phase response across channels, with crosstalk attenuation of 105 dB at 10 kHz - critical for multi-channel instrumentation where inter-channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 3 MHz typical - enables stable closed-loop operation up to audio frequencies without external compensation. |
| Input noise voltage | 8 nV/√Hz at 1 kHz - supports low-noise amplification in precision sensor interfaces. |
| Supply voltage range | ±5 V to ±15 V - compatible with standard dual-rail analog systems including industrial PLC I/O modules. |
| Input offset voltage | 0.5–6 mV at 25°C - suitable for DC-coupled applications requiring moderate accuracy without trimming. |
| Slew rate | 1.7 V/µs - sufficient for 10 Vpp signals up to ~270 kHz without distortion. |
| Common-mode rejection | 70–90 dB - maintains accuracy in noisy industrial environments with ground differentials. |
| Total supply current | 5–11.3 mA - enables low-power multi-amplifier designs in space-constrained embedded systems. |
Pinout & Package
RC4136N is housed in a 14-pin plastic dual in-line package (PDIP-N), with thermal impedance of 80°C/W and lead finish NIPDAU. The package supports through-hole mounting and is rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | IN– (inverting input) | Differential input node per amplifier; referenced to internal bias network. |
| 2, 6, 10, 13 | IN+ (non-inverting input) | Differential input node per amplifier; supports rail-to-rail common-mode range up to ±12 V. |
| 3, 7, 11, 14 | OUT (output) | Class-A/B output stage capable of ±10 V swing into 2 kΩ load. |
| 4 | VCC– | Negative supply rail connection for all four amplifiers; must be decoupled locally. |
| 14 | VCC+ | Positive supply rail connection for all four amplifiers; shared power domain. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external capacitor and reduces BOM count. |
| Continuous short-circuit protection | Output current limited to prevent damage during fault conditions - enables reliable operation in unattended systems. |
| Wide common-mode input range | ±12 V at ±15 V supplies - allows direct interfacing with sensors operating near supply rails. |
| No latch-up behavior | CMOS-free bipolar process ensures immunity to input overvoltage-induced latch-up - improves system robustness. |

Use Value: ±12 V input range and ±10 V output swing enable full utilization of 12-bit or 16-bit ADC reference spans. |
| Analog Voltage Follower Networks | Legacy µA741 Drop-In Replacement Systems |
Use Scenario: Buffering high-impedance sources such as potentiometers, DAC outputs, or photodiode transimpedance stages. IC Role / Device Role / Timing Role: Unity-gain buffer isolating source impedance from downstream loading effects. Use Value: High common-mode input range and no latch-up allow safe operation even when input exceeds supply rails by ≤3 V. | Use Scenario: Upgrading aging test equipment and lab instruments originally designed around µA741-based quad implementations. IC Role / Device Role / Timing Role: Pin-compatible functional replacement for legacy µA741-derived quad layouts. Use Value: Identical pinout and electrical similarity to µA741 simplify redesign while adding short-circuit protection and improved noise performance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324N | Single-supply operation (3–32 V), lower slew rate (0.5 V/µs), higher input offset (2–7 mV), no short-circuit protection. | Preferred for battery-powered or single-rail systems; unsuitable for precision dual-supply signal chains requiring fast settling. | Select LM324N only when single-supply operation or ultra-low quiescent current (<1.2 mA per amp) is mandatory. |
| TL084CN | JFET-input architecture, higher input impedance (>10¹² Ω), higher slew rate (13 V/µs), wider supply range (±18 V), but requires external compensation for unity-gain stability. | Better for high-impedance source buffering and wideband AC-coupled applications; not drop-in due to compensation dependency. | Choose TL084CN when input bias current <200 pA or bandwidth >10 MHz is required - not for direct RC4136N replacement without layout changes. |
Compared with LM324N and TL084CN, the RC4136N uniquely combines internal unity-gain compensation, short-circuit protection, and µA741 compatibility in a PDIP-14 package - making it optimal for legacy dual-supply industrial upgrades where reliability and design continuity are critical.

FAQ
What is the operating temperature range specified for the RC4136N?
The RC4136N is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating aligns with standard industrial control environments and distinguishes it from the obsolete military-grade RM4136 (–55°C to 125°C) and automotive-grade RV4136 (–40°C to 85°C). RC4136N maintains full electrical specifications across this range, including input offset voltage and slew rate.
Does the RC4136N require external frequency compensation components?
No, the RC4136N features internal frequency compensation optimized for unity-gain stability. Unlike JFET-input op-amps such as TL084CN, it does not require external capacitors or resistors to prevent oscillation in follower or gain-of-one configurations - simplifying PCB layout and reducing component count in analog signal paths.
Is the RC4136N pin-compatible with the µA741 quad equivalent?
The RC4136N is designed to be interchangeable with Raytheon's RC4136, RM4136, and RV4136, and electrically similar to the µA741 per amplifier - but it uses a 14-pin PDIP layout distinct from the 8-pin µA741. While not pin-for-pin compatible with a single µA741, the RC4136N provides four µA741-like amplifiers in one IC with matching functional pin assignments per channel (IN+, IN–, OUT, VCC±).
What is the maximum continuous output short-circuit duration supported by the RC4136N?
The RC4136N provides continuous short-circuit protection per amplifier, allowing indefinite output shorting to ground under recommended operating conditions (±5 V to ±15 V supplies). This feature eliminates need for external current-limiting circuitry in fault-prone industrial interfaces - a key reliability advantage over unprotected op-amps like early µA741 variants.
How does the RC4136N's input noise performance compare to modern low-noise op-amps?
The RC4136N delivers 8 nV/√Hz input voltage noise at 1 kHz - competitive with many contemporary general-purpose op-amps but higher than dedicated low-noise types (e.g., OPA211: 1.1 nV/√Hz). It remains suitable for non-critical sensor amplification where cost, availability, and proven field reliability outweigh ultra-low-noise requirements.
