Product details
Overview
NE5534PSR from Texas Instruments is a precision, low-noise operational amplifier optimized for high-fidelity audio and instrumentation applications. It delivers 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and 13 V/μs slew rate with ±3 V to ±20 V dual-supply operation and ±12 V output swing into 600 Ω. Its internal gain ≥3 compensation enables stable operation without external phase compensation in most configurations.
For engineers reviewing the NE5534PSR datasheet, NE5534PSR pinout, NE5534PSR application, or NE5534PSR equivalent, this page provides verified technical context, package-specific pin functions, real-world design values, and validated alternative options - all aligned to TI's SLOS070D specification for the SA5534 family variant in PS (SOP-8) packaging.
Technical Context
The NE5534PSR is a member of the SA5534x series - the industrial-grade (-40°C to +85°C) variant of the NE5534 family - manufactured in TI's PS (plastic small-outline) 8-pin package. It features fully differential input stage with bipolar transistor topology, internal frequency compensation for minimum gain ≥3, and dedicated BALANCE/COMP/BAL pins enabling precise offset nulling and external compensation via capacitor between COMP and COMP/BAL terminals.
This device operates as a dual-supply op-amp with rail-to-rail input common-mode range (±12 V at ±15 V supplies) and robust output short-circuit protection. Its 100 dB CMRR and 100 V/mV DC gain support high-accuracy closed-loop configurations in servo, medical, and telecom channel amplifiers where signal integrity and dc stability are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534DR | Same core silicon, SOIC-8 package, 0°C to 70°C temp range, no PS-package lead-form geometry | Limited to commercial temperature grade; unsuitable for extended industrial environments | Select NE5534DR only for cost-sensitive, ambient-temperature lab or consumer audio designs |
| OPA1612AIDR | Lower 1.1 nV/√Hz noise, rail-to-rail output, higher 40 MHz GBW, but requires external offset trim and lacks COMP/BAL pins | Superior noise performance but no built-in compensation flexibility; not drop-in for legacy NE5534PSR layouts | Choose OPA1612AIDR when upgrading for ultra-low-noise audio paths and redesigning PCB layout is feasible |
Compared with NE5534PSR, NE5534DR trades industrial temperature range for lower cost and broader distribution, while OPA1612AIDR offers quantum-noise improvement at the expense of pin compatibility and external compensation capability - making NE5534PSR uniquely suited for field-replaceable, temperature-resilient analog signal conditioning where proven stability matters.

FAQ
What is the operating temperature range for NE5534PSR?
The NE5534PSR is rated for industrial operation from −40°C to +85°C. This wider range distinguishes it from the commercial-grade NE5534DR (0°C to 70°C) and makes NE5534PSR suitable for deployment in outdoor telecom equipment, factory-floor controllers, and medical devices requiring environmental resilience. The datasheet specifies full electrical performance across this entire span.
Does NE5534PSR require external compensation capacitors?
NE5534PSR is internally compensated for stable operation at gains ≥3, so no external capacitor is required for basic unity-gain or inverting configurations. However, the COMP and COMP/BAL pins allow optional external capacitor placement to tailor bandwidth and phase margin - for example, adding 22 pF improves stability driving capacitive loads or optimizing for specific closed-loop gain settings.
How do I perform offset nulling on NE5534PSR?
To null input offset voltage on NE5534PSR, connect a 10-kΩ potentiometer between BALANCE (Pin 1) and COMP/BAL (Pin 8), with its wiper grounded. Adjust the pot until output voltage equals zero with inputs shorted and supplies applied. This procedure achieves <1 mV residual offset and is documented in TI's SLOS070D Figure 10 and Application Note SLOA045.
Can NE5534PSR operate from a single supply?
Yes, NE5534PSR can operate from a single supply by referencing its VCC− pin to ground and applying positive voltage to VCC+. However, input common-mode and output swing become asymmetric: VICR extends to within ~2 V of ground, and output cannot swing below ~1.5 V. For true rail-to-rail input/output, consider newer alternatives - NE5534PSR excels in dual-supply configurations like ±12 V or ±15 V.
What is the maximum safe supply voltage for NE5534PSR?
The absolute maximum supply voltage for NE5534PSR is ±22 V - exceeding this risks permanent damage. TI recommends operating within ±3 V to ±20 V per the Recommended Operating Conditions table. At ±18 V, NE5534PSR delivers 32 V peak-to-peak output swing into 600 Ω, confirming headroom margins for typical audio and instrumentation use cases without violating limits.
