Product details
Overview
RC4559PG4 from Texas Instruments is a dual high-performance operational amplifier designed for low-noise audio preamplification and precision signal conditioning. It delivers unity-gain bandwidth ≥3 MHz, slew rate ≥1.5 V/µs, input offset voltage ≤6 mV (max at 25°C), and equivalent input noise voltage ≤2 µV/√Hz (20 Hz–20 kHz), operating across 0°C to 70°C with ±15 V supplies.
For engineers reviewing the RC4559PG4 datasheet, RC4559PG4 pinout, RC4559PG4 application, or RC4559PG4 equivalent, key selection criteria include matched amplifier gain/offset, no external frequency compensation requirement, unlimited output short-circuit duration, wide common-mode input range (±12 V), and compatibility with legacy Raytheon RC4559 designs.
Technical Context
The RC4559PG4 integrates two independent high-slew-rate op-amps in a single PDIP-8 package, each featuring internally compensated DC-coupled architecture with no latch-up risk and guaranteed dynamic performance exceeding general-purpose amplifiers. Its input stage supports ±15 V common-mode voltage and tolerates ±30 V differential input.
Electrical matching between amplifiers is specified at ±0.2 mV input offset voltage and ±7.5 nA input offset current (25°C), enabling precise dual-channel operation in instrumentation and balanced audio paths without external trimming.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RC4558P | Lower unity-gain bandwidth (1.5 MHz typ), higher input offset (10 mV max), no guaranteed matching specs | Suitable for cost-sensitive non-audio applications where precision matching is unnecessary | Select RC4558P only when noise, speed, and inter-amplifier matching are not critical |
| NE5532P | Higher slew rate (9 V/µs), lower noise (0.95 µV/√Hz), but requires external compensation for gains <5 and has different pinout | Better suited for high-fidelity audio power amplification stages, not drop-in replacement | Choose NE5532P for demanding audio output stages; RC4559PG4 remains preferred for input-stage matching and simplicity |
Compared with RC4558P and NE5532P, the RC4559PG4 uniquely balances low-noise performance, guaranteed inter-amplifier matching, internal compensation, and legacy Raytheon RC4559 compatibility-making it optimal for precision dual-channel signal paths where layout simplicity and DC accuracy are prioritized over raw speed or ultra-low noise.

FAQ
What is the operating temperature range for the RC4559PG4?
The RC4559PG4 is characterized for operation from 0°C to 70°C ambient temperature. This commercial-grade rating aligns with its intended use in audio equipment, test instruments, and industrial control interfaces where environmental extremes are not expected. The device maintains specified electrical performance-including input offset voltage, slew rate, and noise-across this full range, with derating applied only for thermal dissipation limits above 500 mW total power.
Is the RC4559PG4 pin-compatible with the original Raytheon RC4559?
Yes, the RC4559PG4 is designed to be interchangeable with the Raytheon RC4559, sharing identical PDIP-8 pinout, electrical specifications, and functional behavior. Texas Instruments explicitly states this interchangeability in the datasheet, confirming compatibility in existing designs without PCB or schematic modification. Both devices support the same supply voltages, input/output voltage ranges, and thermal limits.
Does the RC4559PG4 require external frequency compensation?
No, the RC4559PG4 does not require external frequency compensation. It is internally compensated for unity-gain stability, allowing direct use in gain-of-one configurations without added capacitors or resistors. This simplifies circuit design and improves reliability in audio and instrumentation applications where phase margin and settling time are critical.
What is the maximum output voltage swing for the RC4559PG4 into a 600 Ω load?
The RC4559PG4 delivers a guaranteed ±9.5 V peak output voltage swing into a 600 Ω load at 25°C with ±15 V supplies. This specification ensures compatibility with professional audio line standards (e.g., +4 dBu ≈ 1.23 V RMS) while maintaining headroom for transients. Performance degrades slightly at temperature extremes but remains within ±9 V across the full 0°C to 70°C range.
How does the RC4559PG4 compare to modern low-noise op-amps like the OPA2134?
The RC4559PG4 offers lower noise than many general-purpose op-amps (2 µV/√Hz), but the OPA2134 achieves 0.8 µV/√Hz with FET inputs and rail-to-rail output. However, the RC4559PG4 provides guaranteed inter-amplifier matching and simpler unity-gain stability-features not present in the OPA2134. For legacy-compatible, matched dual-channel designs, RC4559PG4 remains functionally distinct and well-supported.
