Product details
Overview
SA5532ADG4 from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity analog signal conditioning in professional audio and precision instrumentation. It delivers 5nV/√Hz input noise voltage at 1kHz, 12MHz unity-gain bandwidth, 100dB common-mode rejection ratio, 5V/μs slew rate, and operates across –40°C to +85°C - enabling use in pro audio mixers and broadcast video infrastructure.
For engineers reviewing the SA5532ADG4 datasheet, SA5532ADG4 pinout, SA5532ADG4 application, or SA5532ADG4 equivalent, key selection criteria include its extended industrial temperature range, SOIC-8 package compatibility, dual-channel low-noise performance, and internal unity-gain compensation for stable closed-loop operation without external compensation.
Technical Context
The SA5532ADG4 integrates two internally compensated op-amps with matched dc and ac characteristics. Its architecture supports rail-to-rail output swing under load (±10V into 600Ω), features input protection diodes and output short-circuit protection, and maintains stable unity-gain operation without external components.
It operates from dual supplies of ±5V to ±15V, exhibits 30kΩ to 300kΩ input resistance, and achieves 10V/mV large-signal voltage gain (min) at full temperature range - making it suitable for DC-coupled gain stages and low-distortion AC amplification in demanding analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 5nV/√Hz typ @ 1kHz - enables high-resolution audio signal amplification with minimal added noise floor |
| Unity-Gain Bandwidth | 12MHz typ - supports wideband audio and video signal processing up to ~1MHz with <0.1dB gain flatness |
| Slew Rate | 5V/μs typ - ensures faithful reproduction of fast transients in audio waveforms without slew-induced distortion |
| CMRR | 100dB typ - rejects power supply and EMI coupling common to both inputs in noisy environments |
| Supply Voltage Range | ±5V to ±15V - allows flexible biasing in legacy ±12V and modern ±15V analog systems |
| Operating Temperature | –40°C to +85°C - qualified for industrial and broadcast equipment deployed in uncontrolled thermal environments |
| Input Offset Voltage | 4mV max @ 25°C - minimizes DC error in precision gain blocks and sensor interface circuits |
Pinout & Package
SA5532ADG4 is housed in an 8-pin SOIC (D) package measuring 4.90mm × 3.91mm, with gull-wing leads and RoHS-compliant NiPdAu plating. It is rated MSL Level-1 (unlimited floor life) and compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output | Amplified output of first op-amp channel; capable of ±10V swing into 600Ω load |
| 2 (1IN–) | Input | Inverting input of first op-amp; accepts differential or single-ended signals with ±13V common-mode range |
| 3 (1IN+) | Input | Noninverting input of first op-amp; includes internal ESD protection diodes to VCC+/VCC– |
| 4 (VCC–) | Power | Negative supply rail; must be decoupled with 0.1μF ceramic capacitor placed adjacent to pin |
| 5 (2IN+) | Input | Noninverting input of second op-amp; electrically isolated but thermally coupled to first channel |
| 6 (2IN–) | Input | Inverting input of second op-amp; shares same noise and offset specifications as Channel 1 |
| 7 (OUT2) | Output | Amplified output of second op-amp channel; fully independent with no crosstalk above –100dB |
| 8 (VCC+) | Power | Positive supply rail; requires local 0.1μF bypass capacitor to suppress supply-induced distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | 0°C to +70°C operating range; identical electrical specs except wider temp drift on offset voltage | Limited to commercial-grade audio gear and embedded PCs without thermal stress | Select when cost sensitivity outweighs extended temperature requirement and system ambient stays below 70°C |
| OPA2134PA | FET-input architecture (0.5pA bias current vs 800nA); lower noise current but higher voltage noise (8nV/√Hz) | Better for high-impedance sources (e.g., piezo sensors); less optimal for low-Z audio lines | Choose for ultra-low input bias current needs where source impedance exceeds 100kΩ |
Compared with NE5532DR and OPA2134PA, SA5532ADG4 uniquely balances industrial temperature range, bipolar-input drive capability, and benchmark voltage noise - making it the preferred choice for pro-audio and broadcast hardware requiring long-term stability under thermal stress.

FAQ
What is the maximum supply voltage for SA5532ADG4?
The absolute maximum supply voltage for SA5532ADG4 is ±18V, but recommended operating conditions specify ±5V to ±15V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability. The device's internal protection circuitry does not guarantee safe operation at ±18V continuously - design margins should maintain VCC± ≤ ±15V per TI SLOS075K Rev K.
Does SA5532ADG4 require external compensation capacitors?
No, SA5532ADG4 is internally compensated for unity-gain stability and does not require external compensation capacitors. Its dominant-pole compensation ensures unconditional stability in inverting, non-inverting, and follower configurations with gains ≥1. Adding external capacitance may degrade phase margin and cause oscillation - TI explicitly advises against it in SLOS075K Section 6.4.
What is the input common-mode voltage range of SA5532ADG4?
The input common-mode voltage range for SA5532ADG4 is ±12V to ±13V with ±15V supplies, meaning inputs can swing from 2V above VCC– to 2V below VCC+. This allows full-rail input operation in most dual-supply configurations. At ±12V supplies, the usable range narrows to ±10V - always verify against actual supply rails per Section 5.5 of the datasheet.
Is SA5532ADG4 pin-compatible with NE5532DR?
Yes, SA5532ADG4 is pin-compatible with NE5532DR - both use the same SOIC-8 (D) package with identical pinout, footprint, and solder profile. However, SA5532ADG4 extends the operating temperature range to –40°C to +85°C versus 0°C to +70°C for NE5532DR, and exhibits tighter parametric drift over temperature, particularly in input offset voltage and CMRR.
What is the typical total supply current for SA5532ADG4?
The typical total supply current for SA5532ADG4 is 8mA (6mA min, 16mA max) with no load and ±15V supplies at 25°C. Current increases linearly with output loading and supply voltage - at ±12V and 10mA output, total ICC rises to ~10.5mA. Thermal derating applies above 70°C ambient, per Section 5.4 thermal metrics in SLOS075K.
