Product details
Overview
NE5534PG4 from Texas Instruments is a low-noise, high-slew-rate operational amplifier designed for precision analog signal conditioning in audio and instrumentation systems. It delivers 3.5 nV/√Hz input noise voltage, 13 V/μs slew rate, and 10 MHz unity-gain bandwidth with ±3 V to ±20 V dual-supply operation - enabling high-fidelity preamplification in professional audio mixing consoles.
For engineers reviewing the NE5534PG4 datasheet, NE5534PG4 pinout, NE5534PG4 application, or NE5534PG4 equivalent, key selection considerations include its external compensation capability (via COMP and COMP/BAL pins), offset nulling support, 8-pin PDIP package compatibility, and guaranteed 0°C to 70°C operating range - critical for legacy industrial and broadcast equipment upgrades.
Technical Context
The NE5534PG4 integrates a fully compensated, internally gain-stable (≥3) bipolar input stage optimized for low-noise, wide-bandwidth performance. Its architecture supports external frequency compensation between COMP and COMP/BAL pins and enables precise DC offset adjustment via the BALANCE and COMP/BAL terminals.
It features input protection diodes, output short-circuit protection, and operates across ±3 V to ±20 V supplies. With 100 dB CMRR and 100 V/mV open-loop gain, it maintains accuracy under varying common-mode conditions and load impedances down to 600 Ω.

| Output Swing | 32 VPP typ at ±18 V / 600 Ω - drives professional line-level loads (−10 dBV to +24 dBu) directly |
| DC Voltage Gain | 100 V/mV typ - ensures <0.1% gain error in precision DC-coupled instrumentation paths |
Pinout & Package
NE5534PG4 is housed in an 8-pin plastic dual in-line package (PDIP), with 0.3-inch body width and through-hole mounting. Pin 1 is BALANCE; pin 2 is IN−; pin 3 is IN+; pin 4 is VCC−; pin 5 is COMP; pin 6 is OUT; pin 7 is VCC+; pin 8 is COMP/BAL.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment terminal | Connects to wiper of 10-kΩ potentiometer for manual input offset trimming |
| IN− (Pin 2) | Inverting input | Accepts feedback network for stable closed-loop configurations (e.g., inverting amplifier) |
| IN+ (Pin 3) | Noninverting input | High-impedance node (>30 kΩ) for sensor or line-level signal injection |
| VCC− (Pin 4) | Negative supply rail | Must be ≤ −3 V and ≥ −22 V; bypassed with 0.1-μF ceramic capacitor to ground |
| COMP (Pin 5) | Compensation output | Provides internal compensation node for external capacitor connection to COMP/BAL |
| OUT (Pin 6) | Amplifier output | Capable of ±16 V swing into 600 Ω; includes short-circuit protection |
| VCC+ (Pin 7) | Positive supply rail | Must be ≥ +3 V and ≤ +22 V; bypassed with 0.1-μF ceramic capacitor to ground |
| COMP/BAL (Pin 8) | Shared compensation/offset terminal | Connects to COMP pin via external capacitor for bandwidth control or to BALANCE for offset nulling |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar input stage | 3.5 nV/√Hz input voltage noise enables microphone preamp use without added noise floor degradation |
| External frequency compensation | COMP–COMP/BAL capacitor (e.g., 22 pF) tailors bandwidth and stability for specific gain configurations |
| Offset voltage nulling | BALANCE and COMP/BAL pins allow <1 mV residual offset after calibration - essential for DC-coupled servo loops |
| High-output drive capability | Delivers 38 mA short-circuit current and sustains 32 VPP into 600 Ω - eliminates need for external buffer stages |
| Wide supply range | Operates from ±3 V (low-power battery systems) to ±20 V (high-dynamic-range audio) without re-biasing |
Applications
| Audio Preamplifiers | Servo Error Amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5534DRG4 | Same electrical specs; SOIC-8 surface-mount package instead of PDIP-8 | Requires PCB redesign for SMT assembly; no through-hole footprint compatibility | Select for new designs prioritizing board space and automated assembly |
| OPA1612AIDR | Lower noise (1.1 nV/√Hz), rail-to-rail output, but ±2.25 V to ±18 V supply range and no COMP/BAL pins | Lacks external compensation and offset nulling - unsuitable for legacy circuit replacements requiring those functions | Choose only when upgrading noise performance is primary and board layout permits functional redesign |
Compared with NE5534PG4, NE5534DRG4 offers identical analog performance in a modern SOIC package but requires layout change, while OPA1612AIDR improves noise by 70% but removes critical legacy features like COMP/BAL-based compensation - making NE5534PG4 irreplaceable in field-serviceable audio hardware.

FAQ
What is the maximum supply voltage rating for NE5534PG4?
The absolute maximum supply voltage for NE5534PG4 is ±22 V. Operation beyond this limit risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±3 V to ±15 V - with full electrical performance guaranteed across that range. The NE5534PG4 can deliver 32 VPP output swing at ±18 V, but sustained operation at ±18 V requires thermal derating per the datasheet's thermal information section.
Does NE5534PG4 support single-supply operation?
Yes, NE5534PG4 supports single-supply operation when biased appropriately - for example, with VCC+ = +15 V and VCC− = ground. However, its input common-mode range extends only to within ~3 V of the negative rail, so input signals must be level-shifted or AC-coupled. The device's internal architecture remains dual-supply optimized, and its full specified performance (e.g., 100 dB CMRR, 32 VPP swing) is validated under dual-supply conditions.
How do I configure external compensation on NE5534PG4?
External compensation on NE5534PG4 is implemented by connecting a capacitor (e.g., 22 pF) between Pin 5 (COMP) and Pin 8 (COMP/BAL). This adjusts the dominant pole to optimize stability for gains below 3 or for specific load conditions. The value is selected based on closed-loop gain and capacitive load - higher values reduce bandwidth but improve phase margin. Do not connect the capacitor to ground or other nodes; the COMP–COMP/BAL path is the only supported configuration per TI's SLOS070D datasheet.
Can NE5534PG4 replace NE5534P in existing designs?
Yes, NE5534PG4 is a direct replacement for NE5534P - both are identical 8-pin PDIP-packaged variants of the NE5534 with identical pinout, electrical specifications, and 0°C to 70°C temperature rating. The "G4" suffix denotes RoHS-compliant lead finish (NIPDAU), while "P" indicates the legacy non-RoHS version. No PCB or schematic changes are required; only material compliance documentation differs.
What is the purpose of the BALANCE and COMP/BAL pins on NE5534PG4?
The BALANCE (Pin 1) and COMP/BAL (Pin 8) pins enable two distinct functions: BALANCE serves as the reference terminal for offset nulling (e.g., connected to one end of a 10-kΩ potentiometer), while COMP/BAL acts as the adjustable node - connected to the potentiometer wiper and the other end tied to VCC−. Together they form a balanced nulling network. COMP/BAL also serves as the external compensation return point when used with the COMP pin (Pin 5), allowing bandwidth tuning without affecting offset adjustment.
