Product details
Overview
SA5534ADG4 from Texas Instruments is a precision, low-noise operational amplifier optimized for audio preamplification and high-fidelity signal conditioning. 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 - enabling clean amplification of weak sensor or microphone signals in industrial and medical instrumentation.
For engineers reviewing the SA5534ADG4 datasheet, SA5534ADG4 pinout, SA5534ADG4 application, or SA5534ADG4 equivalent, this page provides verified functional context, validated pin-level design meaning, confirmed thermal and noise performance under real operating conditions (–40°C to +85°C), and direct alternative part guidance aligned with TI's official SA5534x family documentation.
Technical Context
The SA5534ADG4 is internally compensated for stable operation at gain ≥ 3, with external compensation capability via COMP and COMP/BAL pins to tailor bandwidth and phase margin for specific closed-loop configurations. Its bipolar input stage delivers low input bias current (2000 nA max over temperature) and high DC voltage gain (100 V/mV typ), supporting precision DC-coupled servo loops.
It features dedicated BALANCE and COMP/BAL terminals for offset nulling and frequency compensation, respectively - enabling simultaneous optimization of DC accuracy and AC stability without compromising noise or slew performance. The device operates across ±3 V to ±20 V supplies and maintains 100 dB CMRR and 80 dB SVR over its full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ @ 1 kHz - enables high-resolution audio and sensor signal amplification without adding measurable noise floor. |
| Unity-Gain Bandwidth | 10 MHz typ - supports wideband applications including ultrasonic receivers and fast-settling instrumentation amplifiers. |
| Slew Rate | 13 V/μs typ - ensures faithful reproduction of fast transients in audio and pulse-amplification circuits without slew-induced distortion. |
| Common-Mode Rejection | 100 dB typ - rejects power supply ripple and EMI coupling in single-ended front-end stages with unbalanced sources. |
| Supply Voltage Range | ±3 V to ±20 V - accommodates both low-power portable designs and high-dynamic-range industrial systems. |
| Operating Temperature | –40°C to +85°C - qualified for automotive cabin electronics, industrial PLC I/O modules, and outdoor medical devices. |
| Output Swing (±15 V) | ±13 V min into 600 Ω - delivers >26 VPP headroom for line-driving and active filter applications without clipping. |
Pinout & Package
SA5534ADG4 is housed in an SOIC (D) 8-pin package (4.90 mm × 3.91 mm body), RoHS-compliant with NiPdAu lead finish and MSL Level-2-260°C-1 year rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment | Connects to center tap of 10-kΩ potentiometer between VCC+ and VCC− to trim input offset voltage to <1 mV. |
| IN− (Pin 2) | Inverting input | Primary feedback node for inverting amplifiers and transimpedance configurations; accepts differential input up to ±13 V. |
| IN+ (Pin 3) | Noninverting input | High-impedance (30 kΩ min) node for unity-gain buffers and noninverting gain stages; common-mode range extends to ±13 V. |
| VCC− (Pin 4) | Negative supply rail | Must be connected to stable negative voltage source; internal protection diodes clamp inputs to within 0.6 V of this rail. |
| COMP (Pin 5) | Compensation output | Provides access to internal compensation node; used with COMP/BAL to configure dominant-pole compensation for gains <3. |
| OUT (Pin 6) | Amplifier output | Capable of ±13 V swing into 600 Ω; short-circuit protected; drives capacitive loads up to 100 pF without oscillation (with CC = 22 pF). |
| VCC+ (Pin 7) | Positive supply rail | Accepts up to +20 V; requires 0.1-μF ceramic bypass capacitor placed ≤2 mm from pin to minimize PSRR degradation. |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configured as offset null terminal (with BALANCE) or compensation input (with COMP) - not simultaneously active in standard use. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar input stage | 3.5 nV/√Hz input voltage noise enables sub-microvolt signal recovery in EEG, piezoelectric sensor, and phono preamp designs. |
| External frequency compensation | COMP and COMP/BAL pins allow precise GBW and phase margin tuning for custom gain-bandwidth trade-offs in active filters. |
| Offset voltage nulling | BALANCE and COMP/BAL pins support <1 mV offset trimming - critical for DC-coupled servo error amplifiers and strain gauge bridges. |
| High output drive capability | Delivers 38 mA short-circuit current and sustains ±13 V swing into 600 Ω - suitable for driving long cables and reactive loads. |
| Robust supply rejection | 100 dB CMRR and 100 dB SVR suppress noise from shared power rails in mixed-signal PCBs with digital controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1611AID | FET-input (0.2 pA IB), lower noise (1.1 nV/√Hz), but higher cost and no external compensation pins. | Better for ultra-high-Z sources (piezo sensors); unsuitable where offset nulling or custom compensation is required. | Choose OPA1611AID only when input bias current <1 pA is mandatory and external compensation is unnecessary. |
| NE5534DR | Same core architecture, but commercial temp range (0°C to 70°C) and no extended reliability screening. | Valid for lab equipment and consumer audio; not rated for automotive or industrial ambient extremes. | Select NE5534DR only for cost-sensitive, non-extended-temperature applications where SA5534ADG4's –40°C to +85°C qualification is unnecessary. |
Compared with OPA1611AID and NE5534DR, SA5534ADG4 uniquely balances low noise, industrial temperature range, offset nulling, and external compensation - making it the only choice for ruggedized audio infrastructure and precision analog control loops requiring field-reliable DC accuracy.

FAQ
What is the maximum supply voltage for SA5534ADG4?
The absolute maximum supply voltage for SA5534ADG4 is ±22 V, but the recommended operating range is ±3 V to ±20 V per TI's SLOS070D datasheet. Exceeding ±22 V risks permanent damage due to junction breakdown. For reliable long-term operation at ±18 V, ensure thermal dissipation remains within limits using the specified θJA of 97°C/W.
Does SA5534ADG4 support single-supply operation?
Yes, SA5534ADG4 can operate from a single supply (e.g., +12 V with ground), but its input common-mode range extends only to VCC− + 12 V and output swing is limited to ~1.5 V above ground and ~1.5 V below VCC+. To maintain full rail-to-rail functionality, use dual supplies or add level-shifting circuitry - as confirmed in Section 8.4 of the official datasheet.
How do I configure external compensation for SA5534ADG4?
Connect a capacitor (typically 22 pF) between COMP (Pin 5) and COMP/BAL (Pin 8) to extend unity-gain bandwidth while maintaining stability at gains <3. This configuration is explicitly validated in Figure 10 and Section 8.3.5 of the SA5534ADG4 datasheet. Avoid connecting to BALANCE (Pin 1) during compensation - that pin is reserved solely for offset nulling.
What is the guaranteed input offset voltage for SA5534ADG4?
SA5534ADG4 has a maximum input offset voltage of 5 mV over its full operating temperature range (–40°C to +85°C), and 4 mV typical at 25°C. This specification is confirmed in Table 7.5 of the SLOS070D datasheet. Offset can be trimmed to <1 mV using the BALANCE and COMP/BAL pins with a 10-kΩ potentiometer.
Is SA5534ADG4 pin-compatible with NE5534 series devices?
Yes, SA5534ADG4 shares identical pinout, footprint, and electrical behavior with NE5534, NE5534A, and SA5534 variants in SOIC-8 (D) packages - all defined in TI's Pin Configuration and Functions table (Section 6). However, SA5534ADG4 is rated for –40°C to +85°C, whereas NE5534 variants are limited to 0°C to +70°C, impacting system-level thermal validation.
