Product details
Overview
SA5532AP 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, and 100dB common-mode rejection ratio, operating across –40°C to +85°C in an 8-pin PDIP package for legacy through-hole PCB integration.
For engineers reviewing the SA5532AP datasheet, SA5532AP pinout, SA5532AP application, or SA5532AP equivalent, this page provides verified electrical specifications, thermal and supply operating limits, real-world application context for pro audio and video infrastructure, and validated alternative options with documented functional differences.
Technical Context
The SA5532AP integrates two internally compensated op-amps optimized for unity-gain stability, featuring input protection diodes and output short-circuit protection. Its bipolar input stage enables high slew rate (5V/μs) and wide common-mode input range (±13V at ±15V supplies), supporting rail-to-rail-compatible signal handling without external compensation.
Designed for dual-supply operation (±5V to ±15V), the SA5532AP maintains low distortion and high DC voltage gain (100V/mV typ) across its full industrial temperature range. Its 6mA total supply current and 97°C/W junction-to-ambient thermal resistance reflect optimization for thermally constrained analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Input Offset Voltage | 4mV typical - ensures low DC error in DC-coupled preamplifier and active filter stages |
Pinout & Package
SA5532AP uses an 8-pin plastic dual in-line package (PDIP) with 0.300-inch body width and 0.100-inch lead pitch, suitable for through-hole assembly and prototyping on breadboards or perfboards.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1 | Output 1 | Amplified signal output of first op-amp channel; drives loads ≥600Ω with ±10V swing |
| 2 | Inverting Input 1 | Differential input node for first channel; accepts feedback networks and signal inversion configurations |
| 3 | Noninverting Input 1 | High-impedance (+) input for first channel; used in buffer, follower, and noninverting gain stages |
| 4 | Negative Supply (VCC–) | Ground reference for dual-supply operation; must be connected to –5V to –15V rail |
| 5 | Noninverting Input 2 | High-impedance (+) input for second channel; electrically isolated from Channel 1 |
| 6 | Inverting Input 2 | Differential input node for second op-amp channel; supports independent gain and feedback design |
| 7 | Output 2 | Amplified signal output of second channel; shares same drive capability and voltage swing as Pin 1 |
| 8 | Positive Supply (VCC+) | Power rail connection for dual-supply operation; must be connected to +5V to +15V |
Key Features

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 |
|---|---|---|---|
| NE5532AP | Same pinout and electrical specs, but rated only for 0°C to +70°C industrial range | Not suitable for extended-temperature deployments such as outdoor broadcast enclosures or factory-floor sensors | Select NE5532AP only for cost-sensitive commercial audio gear operating in controlled environments |
| OPA2134PA | FET-input architecture; lower input bias current (1pA vs 800nA), higher input impedance, but higher 8nV/√Hz noise | Better for high-Z sensor interfaces (e.g., piezoelectric pickups); less optimal for low-impedance audio line driving | Choose OPA2134PA when ultra-low input current dominates over noise floor; avoid where 5nV/√Hz is critical |
Compared with SA5532AP, NE5532AP trades temperature range for lower unit cost in benign environments, while OPA2134PA shifts design priority from noise minimization to input impedance and bias current - requiring circuit revalidation for gain-setting resistors and stability compensation.

FAQ
What is the maximum supply voltage for SA5532AP?
The SA5532AP has an absolute maximum supply voltage of ±18V per rail, but its recommended operating range is ±5V to ±15V. Exceeding ±18V risks permanent damage due to internal junction breakdown. For reliable long-term operation, maintain VCC+ ≤ +15V and VCC– ≥ –15V, with proper 0.1μF ceramic bypass capacitors placed near Pins 4 and 8.
Does SA5532AP require external compensation for unity-gain operation?
No, SA5532AP is internally compensated for stable unity-gain operation across its full specified temperature and supply range. This eliminates the need for external compensation capacitors in follower, inverting, or noninverting configurations with gain ≥1, reducing component count and layout sensitivity compared to decompensated op-amps.
Can SA5532AP be used in single-supply applications?
Yes, SA5532AP can operate from a single supply (e.g., +10V and GND) by biasing both inputs and outputs to mid-rail using resistor dividers or dedicated reference ICs. However, its input common-mode range extends only to within ~2V of the negative rail, so GND-referenced designs require careful level-shifting to avoid clipping or phase reversal.
What is the thermal resistance (θJA) of SA5532AP in PDIP package?
The SA5532AP in 8-pin PDIP package has a junction-to-ambient thermal resistance (θJA) of 85°C/W, as specified in the TI datasheet. This value assumes standard JEDEC test conditions (single-layer board, 1-inch² copper pad). Actual thermal performance improves with PCB copper area, thermal vias, and airflow - critical for sustained output loading above 10mA per channel.
How does SA5532AP differ from SA5532ADR in terms of packaging and use case?
SA5532AP uses an 8-pin PDIP package for through-hole prototyping and legacy manufacturing, while SA5532ADR uses an SOIC-8 surface-mount package optimized for automated assembly and space-constrained PCBs. Both share identical electrical specifications and temperature rating (–40°C to +85°C), but SA5532AP offers easier hand-soldering and socket compatibility during development and repair.
