Texas Instruments RC4580IPE4

Overview

RC4580IPE4 from Texas Instruments is a dual audio operational amplifier optimized for high-fidelity preamplification, active filtering, and headphone drive applications. It delivers 12MHz gain-bandwidth product, 5V/μs slew rate, 0.8μVrms input noise voltage, 0.0005% total harmonic distortion at 1kHz, and operates from ±2V to ±16V supply rails.

For engineers reviewing the RC4580IPE4 datasheet, RC4580IPE4 pinout, RC4580IPE4 application, or RC4580IPE4 equivalent, key selection criteria include low-noise audio signal conditioning, rail-compatible dual-channel operation in space-constrained designs, and compatibility with legacy 4580-family layouts requiring minimal redesign effort.

Technical Context

The RC4580IPE4 implements two independent high-slew-rate op-amps in a single monolithic die, each featuring fully differential input stage and Class-AB output stage capable of ±50mA output current. Its internal architecture supports stable unity-gain operation up to 12MHz while maintaining 110dB CMRR and 110dB PSRR across –40°C to 125°C.

Designed specifically for audio signal chains, the device uses matched transistor pairs to minimize input offset drift (<3mV max) and achieves 0.0005% THD+N at 5V_PP, 1kHz, 2kΩ load - enabling clean amplification in tone control, phono preamp, and line-level buffering stages without external trimming.

FAQ

What is the maximum operating supply voltage for RC4580IPE4?

The RC4580IPE4 has an absolute maximum supply voltage rating of ±18V, but its recommended operating range is ±2V to ±16V. Operation at ±18V risks permanent damage per TI's Absolute Maximum Ratings table. For reliable long-term use in audio applications, design with ±15V supplies and include 0.1μF ceramic bypass capacitors at both VCC+ and VCC– pins of the RC4580IPE4 to suppress supply noise and ensure stability.

Is RC4580IPE4 pin-compatible with NE5532?

Yes, RC4580IPE4 is pin- and function-compatible with NE5532 in the 8-pin PDIP package, sharing identical pin assignments for VCC+, VCC–, 1IN+, 1IN–, 1OUT, 2IN+, 2IN–, and 2OUT. However, RC4580IPE4 offers lower input noise (0.8μVrms vs. 5μVrms) and slightly lower slew rate (5V/μs vs. 10V/μs), making it preferable for noise-sensitive audio stages where extreme slew is not required.

Can RC4580IPE4 drive 32Ω headphones directly?

Yes, RC4580IPE4 can drive 32Ω headphones directly due to its ±50mA output current capability per channel. When configured as a unity-gain buffer with appropriate DC servo feedback, the RC4580IPE4 delivers 125mW into 32Ω at <0.0005% THD, eliminating the need for external output transistors or dedicated headphone amplifier ICs in compact portable audio designs.

What is the input offset voltage specification for RC4580IPE4?

The RC4580IPE4 has a maximum input offset voltage of 3mV at TA = –40°C to 125°C, with typical value of 0.5mV. This specification is measured with source resistance <10kΩ and applies across the full operating temperature range. For precision DC-coupled applications like instrumentation amplifiers, the RC4580IPE4's low offset supports sub-mV accuracy without external trimming, provided layout minimizes thermal gradients across the package.

Does RC4580IPE4 support single-supply operation?

Yes, RC4580IPE4 supports single-supply operation by biasing both inputs within the common-mode input voltage range (–13.5V to +13.5V at ±15V supplies). When operated from a +12V single supply, configure the noninverting inputs at VCC/2 via resistor divider and AC-couple inputs/outputs. The RC4580IPE4 maintains full functionality including 0.0005% THD and 12MHz GBW in this mode, making it suitable for battery-powered audio devices where dual rails are impractical.
