Product details
Overview
TL5580IDG4 from Texas Instruments is a dual bipolar operational amplifier optimized for precision analog signal conditioning in ±2 V to ±18 V supply systems. It delivers 12 MHz gain-bandwidth, 5 V/µs slew rate, 7 nV/√Hz input noise at 1 kHz, and ≤1.5 mV input offset voltage (max) - enabling high-fidelity audio amplification, active filter implementation, and industrial sensor signal conditioning.
For engineers reviewing the TL5580IDG4 datasheet, TL5580IDG4 pinout, TL5580IDG4 application, or TL5580IDG4 equivalent, this page provides verified technical context, SOIC-8 package mapping, real-world use cases in audio and data acquisition, and validated alternative options with documented functional trade-offs.
Technical Context
The TL5580IDG4 integrates two matched bipolar-input op-amps in a single SOIC-8 package, supporting rail-to-rail output swing into 2 kΩ loads and stable operation across ±2 V to ±18 V dual supplies. Its architecture achieves low THD (0.0005% typ) and high CMRR (110 dB typ) without external compensation.
It features internal frequency compensation for unity-gain stability, operates over –40°C to +85°C, and maintains 90 dB large-signal voltage gain (AVD) and 85 dB supply-voltage rejection (kSVR) under full temperature range - making it suitable for unregulated industrial power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2 V to ±18 V - supports wide-range industrial and test-equipment power rails without external regulation |
| Gain Bandwidth | 12 MHz typ - enables stable closed-loop operation up to 100 kHz with ≥100× gain in active filters |
| Slew Rate | 5 V/µs typ - preserves transient fidelity in audio and pulse-amplification circuits |
| Input Offset Voltage | ≤1.5 mV max at 25°C - reduces DC error in precision instrumentation and sensor front-ends |
| Input Noise Voltage | 7 nV/√Hz typ at 1 kHz - critical for low-level signal amplification in data-acquisition systems |
| Total Harmonic Distortion | 0.0005% typ at 1 kHz - meets high-fidelity audio line-driver requirements |
| Common-Mode Rejection | 110 dB typ - rejects interference in noisy industrial measurement environments |
Pinout & Package
TL5580IDG4 is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with 1.27 mm lead pitch, 3.91 mm body width, and 4.9 mm length. Pin 1 is located at the top-left corner adjacent to the notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives 600 Ω loads directly; swing limited to ±13.5 V at ±15 V supply |
| 2 | 1IN− | Inverting input of first amplifier - high-impedance node requiring guarded layout for low-noise performance |
| 3 | 1IN+ | Non-inverting input of first amplifier - matched to Pin 2 for optimal CMRR and offset cancellation |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor |
| 5 | 2IN− | Inverting input of second amplifier - electrically isolated from first channel but shares thermal substrate |
| 6 | 2IN+ | Non-inverting input of second amplifier - independent biasing path; no crosstalk below –80 dB |
| 7 | 2OUT | Output of second amplifier - identical AC/DC specs to Pin 1; usable for dual-path signal processing |
| 8 | VCC+ | Positive supply rail - requires symmetric decoupling to VCC− for optimal PSRR |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel precision architecture | Two fully independent op-amps on one die - enables matched gain/phase response in stereo audio or differential sensor interfaces |
| Low-noise bipolar input stage | 7 nV/√Hz input noise at 1 kHz - outperforms JFET-input alternatives in bandwidth-critical low-noise applications |
| Wide supply range support | Operates from ±2 V to ±18 V - eliminates need for separate LDOs in mixed-voltage industrial systems |
| High-output drive capability | Drives 600 Ω loads with <0.1% THD - suitable for line-level audio outputs without external buffers |
| Stable unity-gain configuration | No external compensation required - simplifies PCB layout and reduces BOM count in active filter designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134PA | FET-input, 8 MHz GBW, 20 V/µs slew, 10 fA IB - lower input bias current but higher voltage noise (12 nV/√Hz) | Better for high-impedance photodiode or piezo sensor interfaces; less optimal for low-noise, wideband audio | Choose OPA2134PA when ultra-low input bias current dominates design priority over noise or bandwidth |
| AD822ARZ | Rail-to-rail output, 1.8 MHz GBW, 3 V/µs slew, 25 nV/√Hz noise - wider supply range (±1.5 V to ±18 V) but lower speed/noise performance | Suitable for battery-powered portable instruments where rail-to-rail output swing is mandatory | Choose AD822ARZ only when rail-to-rail output is required and 12 MHz bandwidth is not needed |
Compared with TL5580IDG4, OPA2134PA trades bandwidth and voltage noise for femtoampere input bias, while AD822ARZ sacrifices speed and noise performance to achieve rail-to-rail output - neither offers direct pin compatibility, and both require schematic and layout revision for substitution.

FAQ
What is the maximum operating supply voltage for TL5580IDG4?
The TL5580IDG4 supports dual-supply operation from ±2 V to ±18 V. Absolute maximum ratings specify ±18 V, but recommended operating conditions limit continuous use to ±16 V to ensure reliability and thermal stability across the full –40°C to +85°C temperature range. Exceeding ±16 V may reduce long-term parametric consistency.
Does TL5580IDG4 support rail-to-rail output swing?
No, TL5580IDG4 does not provide rail-to-rail output. At ±15 V supply, its typical output swing is ±13.5 V into 2 kΩ loads, meaning it saturates approximately 1.5 V below VCC+ and above VCC−. This limitation is inherent to its bipolar output stage and must be accounted for in headroom-sensitive designs.
Is TL5580IDG4 pin-compatible with other dual op-amps in SOIC-8 packages?
TL5580IDG4 follows standard SOIC-8 pinout conventions (dual op-amp, dual supply), but it is not pin-compatible with industry-standard parts like LM358 or TL072 due to differing internal channel assignments and supply pin locations. Substitution requires verification of pin mapping and circuit-level validation.
What is the input offset voltage specification for TL5580IDG4 over temperature?
TL5580IDG4 has a maximum input offset voltage of 1.5 mV at 25°C and 2.0 mV over the full –40°C to +85°C operating range. Its average temperature coefficient is 1.8–5 µV/°C, meaning offset drift remains predictable and bounded - critical for DC-coupled sensor interfaces where calibration intervals exceed six months.
Can TL5580IDG4 drive 600 Ω loads without distortion?
Yes, TL5580IDG4 is explicitly characterized to drive 600 Ω loads with ≤0.0005% THD at 1 kHz and 5 Vrms output. This capability is confirmed in the datasheet's Electrical Characteristics table and Typical Characteristics Figure 11, making it suitable for professional audio line-driving applications without external buffer stages.
