Product details
Overview
SA5532D from Texas Instruments is a dual low-noise operational amplifier designed for high-fidelity audio and precision analog signal conditioning. It delivers 5nV/√Hz input noise voltage at 1kHz, 12MHz unity-gain bandwidth, and 100dB common-mode rejection ratio, operating across –40°C to +85°C in SOIC-8 packaging for pro-audio mixers and broadcast video infrastructure.
For engineers reviewing the SA5532D datasheet, SA5532D pinout, SA5532D application, or SA5532D equivalent, this page provides verified specifications, thermal and electrical performance data, SOIC-8 terminal mapping, real-world use cases in audio and video systems, and two confirmed alternative parts with documented functional and temperature-range differences.
Technical Context
The SA5532D is internally compensated for stable unity-gain operation and features input-protection diodes plus output short-circuit protection. Its bipolar input stage enables high DC voltage gain (100V/mV typ) and low input bias current (200–800nA), while maintaining rail-to-rail output swing capability under ±15V supply conditions.
It operates over an extended industrial temperature range (–40°C to +85°C), distinguishing it from NE5532 variants (0°C to +70°C). The device supports dual-supply configurations only and requires 0.1μF ceramic bypass capacitors at each supply pin for optimal noise immunity and stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 5nV/√Hz typ at 1kHz - enables high-SNR audio amplification without audible hiss in preamp stages |
| Unity-Gain Bandwidth | 12MHz typ - supports wideband signal conditioning up to ~10MHz before phase margin degradation |
| Common-Mode Rejection | 100dB typ - rejects power supply ripple and EMI coupling in differential-input configurations | DC Voltage Gain | 100V/mV typ (100,000 V/V) - ensures precise closed-loop gain accuracy in sensor interface circuits |
| Slew Rate | 5V/μs typ - preserves transient fidelity in fast-slewing audio waveforms and video sync signals |
| Supply Voltage Range | ±5V to ±15V - compatible with standard ±12V and ±15V analog rails in professional equipment |
| Operating Temperature | –40°C to +85°C - qualified for industrial and broadcast environments where ambient extremes occur |
Pinout & Package
SA5532D 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 | First amplifier output; drives loads ≥600Ω with full ±13V swing under ±15V supplies |
| 2 (1IN–) | Input | Inverting input of first op-amp; accepts differential or single-ended feedback networks |
| 3 (1IN+) | Input | Noninverting input of first op-amp; referenced to system ground or bias network |
| 4 (VCC–) | Power | Negative supply rail connection; must be decoupled with 0.1μF ceramic capacitor |
| 5 (2IN+) | Input | Noninverting input of second op-amp; electrically isolated from first channel |
| 6 (2IN–) | Input | Inverting input of second op-amp; supports independent gain-setting resistor networks |
| 7 (OUT2) | Output | Second amplifier output; fully independent channel with identical AC/DC specs |
| 8 (VCC+) | Power | Positive supply rail connection; requires local 0.1μF ceramic bypass to ground |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Noise | 5nV/√Hz at 1kHz - minimizes audible noise floor in microphone preamplifiers and line-level buffers |
| High Output Drive | 38mA short-circuit current - sustains 600Ω loads without clipping in active filter or driver stages |
| Internal Unity-Gain Compensation | Stable at Av = 1 - eliminates need for external compensation in most gain-of-one applications |
| Input Protection Diodes | Integrated clamping - prevents latch-up when input exceeds supply rails by >0.6V |
| Output Short-Circuit Protection | Current-limited output - survives indefinite shorts to either rail without damage |
Applications

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 |
|---|---|---|---|
| SA5532DR | Same silicon, active production status, 2500-piece tape-and-reel packaging | Identical electrical specs and temperature range; preferred for volume manufacturing | Select SA5532DR for new designs requiring guaranteed long-term availability and standard logistics support |
| NE5532DR | Same architecture but rated 0°C to +70°C; lower max CMRR (70dB min) and higher input offset (5mV max) | Limited to commercial-temperature applications like consumer AV receivers and DVD players | Choose NE5532DR only if cost sensitivity outweighs extended temperature and precision requirements |
Compared with SA5532D, SA5532DR offers assured supply continuity and identical performance, while NE5532DR trades industrial temperature range and tighter DC specs for lower cost in non-critical environments - making SA5532D the optimal choice for ruggedized audio and broadcast systems.

FAQ
What is the operating temperature range of the SA5532D?
The SA5532D is specified for operation from –40°C to +85°C, qualifying it for industrial and broadcast equipment deployed in uncontrolled thermal environments. This extended range distinguishes it from NE5532 variants (0°C to +70°C) and confirms its suitability for rack-mounted audio gear and outdoor video encoders where ambient temperatures fluctuate widely. SA5532D maintains full electrical performance across this entire span.
Does the SA5532D require external compensation for unity-gain stability?
No, the SA5532D is internally compensated for unity-gain operation, meaning it remains stable with closed-loop gain ≥1 without added external components. This simplifies design in buffer, follower, and gain-of-one active filter applications. The internal compensation ensures ≥45° phase margin at 12MHz, eliminating risk of oscillation in standard configurations per TI SLOS075K datasheet Section 6.3.1.
What is the maximum supply voltage for the SA5532D?
The SA5532D supports a maximum supply voltage of ±15V (30V total), with absolute maximum ratings limiting VCC+ to +18V and VCC– to –18V. Operation beyond ±15V risks exceeding thermal dissipation limits and may trigger permanent damage per Section 5.1 of the datasheet. For reliable long-term operation, maintain supply rails within ±5V to ±15V, especially under full-output-swing conditions.
How does the SA5532D compare to the SA5532DR in terms of availability and marking?
The SA5532D is marked "SA5532" and listed as obsolete in TI's packaging addendum, whereas SA5532DR carries identical marking and is actively produced in 2500-piece tape-and-reel format. Both share identical electrical specs and SOIC-8 packaging, but SA5532DR is TI's recommended replacement for new designs due to assured supply continuity, standard logistics, and full documentation support - making SA5532D appropriate only for legacy repair or limited-batch reuse.
Can the SA5532D be used in single-supply configurations?
No, the SA5532D is not designed for true single-supply operation. Its input common-mode range extends to ±12V (with ±15V supplies), and output swing is symmetrical about ground - requiring dual ±V rails for proper biasing. While it can operate with asymmetric supplies (e.g., +15V/–5V), it lacks rail-to-rail input or output capability and exhibits degraded performance near supply rails. For single-supply applications, TI recommends alternatives like TLV2462 or OPA2350.
