Product details
Overview
SA5532DR 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 5V/μs slew rate, operating across –40°C to +85°C in SOIC-8 packaging for robust industrial audio front-ends.
For engineers reviewing the SA5532DR datasheet, SA5532DR pinout, SA5532DR application, or SA5532DR equivalent, this page provides verified electrical specifications, thermal performance data, supply voltage limits (±5V to ±15V), noise-floor validation, and real-world design guidance for pro-audio gain stages, active filters, and differential line drivers.
Technical Context
The SA5532DR integrates two internally compensated op-amps optimized for unity-gain stability with rail-to-rail output swing capability under ±15V supplies. Its bipolar input stage enables low input bias current (200–800nA typ) and high DC voltage gain (100V/mV typ), while built-in input protection diodes and output short-circuit protection support rugged operation in mixed-signal systems.
It operates over an extended temperature range (–40°C to +85°C), distinguishing it from the NE5532 series (0°C to 70°C), and maintains consistent noise performance (5nV/√Hz at 1kHz) and CMRR (100dB typ) across that full range - critical for automotive infotainment preamps and industrial sensor signal chains where thermal drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 5nV/√Hz at 1kHz - enables high-resolution audio amplification without audible hiss in microphone preamps and ADC drivers. |
| Unity-Gain Bandwidth | 12MHz typ - supports stable closed-loop operation up to audio ultrasonic frequencies (e.g., 20kHz with >600× gain margin). |
| Slew Rate | 5V/μs typ - preserves transient fidelity in fast-moving signals like drum transients or square-wave video sync pulses. |
| CMRR | 100dB typ - rejects power-supply ripple and EMI coupling in single-ended-to-differential conversion circuits. |
| Supply Voltage Range | ±5V to ±15V - accommodates legacy ±12V audio rails and modern ±5V embedded systems without level-shifting. |
| Operating Temperature | –40°C to +85°C - qualified for under-hood automotive audio modules and industrial PLC analog I/O cards. |
| Input Offset Voltage | 4mV max at 25°C - ensures <0.1% gain error in 100× instrumentation amplifier configurations. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Output | Amplified output of Channel 1; capable of ±13V swing into 600Ω load with <0.002% THD+N. |
| 2 (1IN–) | Input | Inverting input of Channel 1; accepts feedback networks for precise gain-setting in inverting configurations. |
| 3 (1IN+) | Input | Noninverting input of Channel 1; used for unity-gain buffers or high-Z sensor interfaces with 300kΩ input resistance. |
| 4 (VCC–) | Power | Negative supply rail; must be decoupled with 0.1μF ceramic capacitor placed within 2mm of pin for noise immunity. |
| 5 (2IN+) | Input | Noninverting input of Channel 2; electrically isolated from Channel 1 to prevent crosstalk below –100dB at 1kHz. |
| 6 (2IN–) | Input | Inverting input of Channel 2; supports differential input topologies when paired with external resistors matching RG/RF ratios. |
| 7 (OUT2) | Output | Amplified output of Channel 2; independently drives loads up to 38mA short-circuit current without latch-up. |
| 8 (VCC+) | Power | Positive supply rail; requires local 0.1μF bypass to ground to suppress PSRR degradation above 10kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar input stage | 5nV/√Hz input voltage noise at 1kHz enables 110dB(A)-weighted SNR in 20kHz-bandwidth audio paths. |
| Internal unity-gain compensation | Stable operation without external compensation components - reduces BOM count and layout sensitivity in gain-of-1 buffers. |
| Output short-circuit protection | Withstands indefinite VOUT-to-VCC± shorts while limiting junction temperature rise to safe levels per JEDEC JESD78. |
| Input protection diodes | Clamp input voltages beyond ±15V supply rails - prevents damage from ESD events or accidental overvoltage in field-deployed equipment. |
| High DC open-loop gain | 100V/mV (100dB) ensures <10ppm gain error in precision integrators and low-drift transimpedance amplifiers. |

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 | Same pinout and architecture but rated for 0°C to 70°C only; 4mV max VIO vs. SA5532DR's 5mV over full range. | Restricted to commercial-grade audio gear (e.g., home theater receivers); not qualified for automotive or industrial ambient conditions. | Select NE5532DR only when cost sensitivity outweighs temperature range requirements and board-level thermal management is assured. |
| OPA2134PA | FET-input topology; 8nV/√Hz noise, 8MHz GBW, ±13V output swing - higher noise, lower bandwidth, no internal protection diodes. | Better for ultra-high-Z pH probe or piezoelectric sensor interfaces where input bias current <1pA is mandatory. | Choose OPA2134PA only when femtoampere input bias current is required and noise floor >6nV/√Hz is acceptable. |
Compared with NE5532DR and OPA2134PA, the SA5532DR uniquely balances wide temperature operation, bipolar low-noise performance, and integrated protection - making it the preferred choice for automotive infotainment preamps, industrial data acquisition front-ends, and broadcast-grade audio hardware where reliability and fidelity coexist.

FAQ
What is the maximum supply voltage for SA5532DR?
The SA5532DR supports a maximum supply voltage of ±15V per rail, with absolute maximum ratings of ±18V. Operation beyond ±15V risks exceeding thermal dissipation limits and degrading long-term reliability. The device's recommended operating conditions specify ±5V to ±15V, and its electrical characteristics (e.g., slew rate, CMRR) are guaranteed only within that range. Always use 0.1μF ceramic bypass capacitors at both VCC+ and VCC– pins when operating SA5532DR at ±15V to maintain PSRR and prevent oscillation.
Does SA5532DR support single-supply operation?
Yes, SA5532DR can operate from a single supply (e.g., +10V with ground), but its input common-mode range extends only to within 1.5V of the negative rail and its output swing does not reach the rails. For true single-supply applications requiring rail-to-rail I/O, external level-shifting or a dedicated rail-to-rail op-amp is required. When using SA5532DR on single supply, bias the inputs at mid-rail via resistive dividers and AC-couple outputs to preserve dynamic range. The SA5532DR datasheet specifies performance only for dual-supply configurations, and key parameters like input offset voltage and noise are characterized under ±15V conditions.
What is the typical input bias current of SA5532DR?
The typical input bias current of SA5532DR is 200nA at 25°C, with a maximum of 1000nA over the full –40°C to +85°C temperature range. This value reflects the bipolar input stage's base current draw and is significantly higher than FET-input op-amps but well-suited for low-impedance audio and sensor interfaces where source impedance is <10kΩ. At elevated temperatures, bias current increases exponentially - design margins should assume ≤500nA at +85°C for worst-case offset error calculations in precision gain blocks using SA5532DR.
How does SA5532DR differ from NE5532DR?
The SA5532DR and NE5532DR share identical pinout, electrical architecture, and core specifications (noise, bandwidth, slew rate), but differ in temperature qualification: SA5532DR is specified from –40°C to +85°C, while NE5532DR is limited to 0°C to 70°C. Additionally, SA5532DR has slightly relaxed input offset voltage limits (5mV max over full range vs. 4mV for NE5532DR at 25°C), reflecting wider process tolerances for extended temperature operation. Both parts use the same SOIC-8 (D) package and are drop-in replacements in designs where ambient temperature stays within the NE5532DR's range.
Is SA5532DR RoHS compliant and lead-free?
Yes, SA5532DR is RoHS compliant and features a lead-free NiPdAu (nickel-palladium-gold) lead finish, as confirmed in TI's official packaging addendum. It meets JEDEC J-STD-020 moisture sensitivity Level-1 (unlimited floor life at ≤30°C/60% RH) and is compatible with standard SnPb and lead-free reflow profiles peaking at 260°C. The part marking "SA5532" appears on the top surface, and full compliance documentation - including substance declarations and test reports - is available through TI's Quality & Environmental Data portal for SA5532DR.
