Product details
Overview
SA5532AD 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, and operates across –40°C to +85°C. It serves as a key front-end gain stage in pro audio mixers and multichannel video transcoders.
For engineers reviewing the SA5532AD datasheet, SA5532AD pinout, SA5532AD application, or SA5532AD equivalent, this page provides verified technical context, real-world design meaning of specifications, package-validated pin functions, and two confirmed alternative parts with documented functional and thermal differences.
Technical Context
The SA5532AD is internally compensated for stable unity-gain operation and features input protection diodes plus output short-circuit protection. Its bipolar input stage enables high slew rate (5V/μs) and low input bias current (200–800nA), while maintaining rail-to-rail output swing capability under ±15V supply.
It supports dual-supply operation only (±5V to ±15V), with specified common-mode input range of ±12V to ±13V and guaranteed DC voltage gain ≥10V/mV over full temperature range. Input offset voltage is 0.5–5mV, and total supply current is 6–16mA per amplifier.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 5nV/√Hz at 1kHz - enables clean amplification of microvolt-level audio signals without adding audible hiss |
| Unity-Gain Bandwidth | 12MHz typ - supports wideband audio (20Hz–20kHz) with ample phase margin and minimal group delay distortion |
| Common-Mode Rejection | 100dB typ - rejects power supply ripple and ground noise in differential-input configurations |
| Slew Rate | 5V/μs typ - preserves transient fidelity of fast-rising audio peaks without slewing-induced distortion |
| Supply Voltage Range | ±5V to ±15V - compatible with standard ±12V and ±15V analog rails in pro audio equipment |
| Operating Temperature | –40°C to +85°C - qualified for industrial and broadcast infrastructure environments |
| Input Offset Voltage | 0.5–5mV - ensures low DC error in DC-coupled gain stages without requiring frequent nulling |
Pinout & Package
SA5532AD is packaged in an 8-pin SOIC (D package), 4.90mm × 3.91mm body size, with gull-wing leads and RoHS-compliant NiPdAu finish. It is rated MSL Level-1 (unlimited floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output | Amplifier 1 output - drives loads ≥600Ω with ±10V swing under ±15V supply |
| 2 (1IN–) | Input | Inverting input of Amp 1 - accepts feedback networks for precise gain control |
| 3 (1IN+) | Input | Noninverting input of Amp 1 - used for buffered or differential input configurations |
| 4 (VCC–) | Power | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor near pin |
| 5 (2IN+) | Input | Noninverting input of Amp 2 - independent channel enables stereo or dual-path processing |
| 6 (2IN–) | Input | Inverting input of Amp 2 - supports individual gain-setting resistors per channel |
| 7 (OUT2) | Output | Amplifier 2 output - electrically isolated from OUT1; shares same supply pins |
| 8 (VCC+) | Power | Positive supply rail - requires local 0.1μF bypass to minimize PSRR degradation |
Key Features
| Feature | Design Value |
|---|---|
| Low input noise density | 5nV/√Hz at 1kHz - critical for microphone preamps and sensor signal chains where SNR dominates performance |
| High DC open-loop gain | ≥10V/mV (100dB) - ensures <0.1% gain error in closed-loop configurations with 100× gain |
| Internal unity-gain compensation | No external compensation required - simplifies layout and eliminates stability tuning for standard gain settings |
| Output short-circuit protection | Withstands indefinite short to either rail - prevents latch-up or thermal runaway during fault conditions |
| Bipolar input stage | 200–800nA input bias current - enables use with high-impedance sources (e.g., passive guitar pickups) without significant DC error |

FAQ
What is the operating temperature range of the SA5532AD?
The SA5532AD is specified for operation from –40°C to +85°C. This industrial temperature range is confirmed in Section 5.3 of the official TI datasheet (SLOS075K) and distinguishes it from the commercial-grade NE5532 variants. The SA5532AD maintains its 5nV/√Hz noise performance and 12MHz bandwidth across this full range, making it suitable for broadcast infrastructure and ruggedized audio equipment where ambient temperatures vary widely. SA5532AD must not be operated outside these limits to guarantee parametric compliance.
Does the SA5532AD require external compensation capacitors?
No, the SA5532AD is internally compensated for unity-gain stability and does not require external compensation capacitors. This is explicitly stated in Sections 3 and 6.1 of the TI datasheet, which confirm internal compensation for unity-gain operation. Adding external capacitors may degrade phase margin or bandwidth. The device achieves stable operation with closed-loop gains ≥1 V/V using only standard feedback resistors. For gains below unity, a different op-amp (e.g., decompensated type) would be required - but SA5532AD is not designed for that mode.
What is the maximum supply voltage for the SA5532AD?
The absolute maximum supply voltage for the SA5532AD is ±18V, as defined in Section 5.1 of the TI datasheet. However, the recommended operating range is ±5V to ±15V. Operation at ±18V risks permanent damage and is not guaranteed to meet specifications. At ±15V, the device delivers its full rated performance: ±10V output swing into 600Ω, 5V/μs slew rate, and 12MHz bandwidth. Exceeding ±15V supply also increases power dissipation beyond safe thermal limits, especially in SOIC packages with RθJA = 97°C/W.
Is the SA5532AD pin-compatible with the NE5532 series?
Yes, the SA5532AD is pin-compatible with all NE5532x and SA5532x variants in the same package - including NE5532DR, NE5532ADR, and SA5532ADR. All share identical 8-pin SOIC (D) pinout: OUT1, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, OUT2, VCC+. This compatibility is confirmed in Figure 4-1 and the Pin Functions table of the TI datasheet. However, note that SA5532AD is marked Obsolete in TI's packaging addendum, while SA5532ADR is Active - so pinout match does not imply identical lifetime support or revision status.
What is the typical input bias current of the SA5532AD?
The typical input bias current of the SA5532AD is 200nA at TA = 25°C, with a maximum of 800nA at 25°C and up to 1000nA over the full –40°C to +85°C range (Section 5.5, IIB parameter). This value reflects its bipolar input stage and is significantly lower than JFET-input op-amps but higher than CMOS types. In practical design, this allows use with source impedances up to ~10kΩ without introducing >1mV of input offset error. For ultra-high-impedance sensors, additional guarding or lower-bias alternatives may be needed - but SA5532AD remains optimal for most audio and video signal chains.
