Product details
Overview
RC4136NG4 from Texas Instruments is a quad general-purpose operational amplifier electrically similar to µA741, 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 RC4136NG4 datasheet, RC4136NG4 pinout, RC4136NG4 application, or RC4136NG4 equivalent, key selection considerations include its 0°C to 70°C temperature rating, plastic DIP-14 package, short-circuit protection, no external frequency compensation requirement, and absence of offset null pins.
Technical Context
The RC4136NG4 integrates four independent op-amps with internally compensated architecture, enabling stable unity-gain operation without external components. Each amplifier supports wide common-mode (±12 V) and differential (±30 V) input voltage ranges, and exhibits no latch-up behavior under overvoltage conditions.
It delivers 1.7 V/µs slew rate at unity gain with 100 pF load and 2 kΩ output resistance, and achieves ≥70 dB common-mode rejection ratio at 25°C. Input bias current is typ. 500 nA, and input offset voltage is 6 mV max at 25°C - consistent with legacy 741-class performance but optimized for cost-sensitive general-purpose use.
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. |
| Supply Voltage Range | ±5 V to ±15 V - supports dual-rail operation in standard analog systems with ±12 V or ±15 V rails. |
| Input Noise Density | 8 nV/√Hz at 1 kHz - suitable for low-level signal amplification where thermal noise dominates. |
| Input Offset Voltage | 6 mV max at 25°C - defines DC error budget in precision DC-coupled stages; no offset null capability provided. |
| Slew Rate | 1.7 V/µs - limits large-signal response time; adequate for <100 kHz full-power sine wave output. |
| Common-Mode Rejection | 70 dB min - ensures robustness against shared-mode interference in non-inverting configurations. |
| Short-Circuit Protection | Continuous - allows safe operation into grounded loads without thermal shutdown or damage. |
Pinout & Package
RC4136NG4 is supplied in a 14-pin plastic dual in-line package (PDIP-N), with 2.54 mm lead pitch and through-hole mounting. The package is RoHS-compliant and rated for 0°C to 70°C ambient operation.

Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external capacitor and simplifies PCB layout. |
| Continuous short-circuit protection | Withstands indefinite output-to-ground shorts without damage or thermal runaway - improves system reliability in fault-prone environments. |
| Wide common-mode input voltage range | ±12 V at 25°C - enables direct interfacing with sensors or transducers operating near supply rails. |
| Low power consumption | 11.3 mA total supply current (all four amps) at ±15 V - reduces thermal load in multi-channel analog modules. |
| Gain and phase match between amplifiers | Typical crosstalk attenuation >105 dB at 10 kHz - preserves channel independence in multi-stage or parallel configurations. |

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 rated (3–32 V), lower slew rate (0.5 V/µs), higher input offset (7 mV max), no short-circuit protection. | Preferred for battery-powered or single-rail systems; unsuitable for high-speed or dual-rail fault-tolerant designs. | Select LM324N only when single-supply operation and ultra-low quiescent current (<1.2 mA per amp) are prioritized over speed and protection. |
| TL084CN | JFET-input architecture, higher slew rate (13 V/µs), wider bandwidth (3 MHz), but requires ±12 V minimum supply and lacks short-circuit protection. | Better for high-frequency AC coupling; not recommended for DC-coupled sensor interfaces with transient overvoltage risk. | Choose TL084CN when low input bias current (<30 pA) and fast settling are critical, and supply margins allow ±12 V operation. |
Compared with LM324N and TL084CN, RC4136NG4 provides unique trade-offs: it retains dual-supply compatibility and built-in short-circuit protection like legacy 741-family parts, while offering better noise and bandwidth than LM324N and greater ruggedness than TL084CN - making it optimal for industrial analog signal chains requiring proven reliability and moderate performance.

FAQ
What is the operating temperature range for RC4136NG4?
The RC4136NG4 is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating aligns with its PDIP-14 packaging and makes it suitable for indoor industrial controls, test equipment, and consumer-grade analog systems where extended temperature operation is not required. RC4136NG4 does not support military or automotive temperature grades.
Does RC4136NG4 include offset null capability?
No, RC4136NG4 does not provide offset null pins or internal trimming capability. Its input offset voltage is specified at 6 mV maximum at 25°C, and this parameter varies across temperature. Designers requiring tighter DC accuracy must implement external calibration or select an op-amp with dedicated null terminals, such as the LM741CH.
Is RC4136NG4 pin-compatible with other members of the RC4136 family?
Yes, RC4136NG4 shares identical pinout and electrical behavior with RC4136N and RC4136D variants. All are quad op-amps in 14-pin packages (PDIP or SOIC), with matching terminal assignments and functional specifications - allowing direct substitution within the same package footprint and temperature grade.
What is the maximum output current capability of RC4136NG4?
RC4136NG4 does not specify a maximum continuous output current, but its continuous short-circuit protection ensures safe operation into 0 Ω loads. Under typical conditions (±15 V supplies, 25°C), output current is limited to approximately ±25 mA before triggering thermal foldback - sufficient for driving 2 kΩ loads with ±10 V swing and most logic-level interface circuits.
Can RC4136NG4 be used in single-supply configurations?
RC4136NG4 is designed for dual-supply operation (±5 V to ±15 V) and lacks rail-to-rail input or output capability. While it can operate with asymmetric supplies (e.g., +15 V and ground), its input common-mode range extends only to ±12 V - meaning inputs must remain ≥3 V above VCC–. For true single-supply applications, consider LM324N or TLC274 instead.
