Product details
Overview
SA5534D from Texas Instruments is a precision low-noise operational amplifier designed for high-fidelity analog signal conditioning in demanding industrial and audio systems. It delivers 3.5 nV/√Hz input noise voltage, 10 MHz unity-gain bandwidth, and ±32 V peak-to-peak output swing (at ±18 V supplies, RL ≥ 600 Ω), operating across –40°C to +85°C. Its internal gain ≥3 compensation, external offset nulling, and frequency compensation capability make it suitable for servo error amplifiers and medical instrumentation front-ends.
For engineers reviewing the SA5534D datasheet, SA5534D pinout, SA5534D application, or SA5534D equivalent, key selection considerations include its extended temperature range (–40°C to +85°C), SOIC-8 package with BALANCE/COMP/BAL/COMP pins enabling precision offset trimming and bandwidth optimization, and verified performance in low-distortion, wide-dynamic-range analog circuits requiring stable DC accuracy and broadband AC response.
Technical Context
The SA5534D implements a bipolar-input, internally compensated op-amp architecture optimized for unity-gain-stable operation at gains ≥3. Its differential input stage uses matched transistor pairs with dedicated BALANCE and COMP/BAL terminals for external offset voltage nulling and frequency compensation via capacitor networks.
It supports dual-supply operation from ±3 V to ±20 V, features input protection diodes and output short-circuit protection, and maintains 100 dB common-mode rejection ratio and 13 V/μs slew rate (CC = 0 pF) - enabling robust performance in noisy industrial environments and high-slew transient applications like active filters and precision buffers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Noise Voltage | 3.5 nV/√Hz typ @ 1 kHz - enables high-resolution signal amplification without degrading SNR in sensor interfaces and mic preamps. |
| Unity-Gain Bandwidth | 10 MHz typ - supports stable closed-loop operation up to 10 MHz at gain = 1, critical for wideband active filters and video line drivers. |
| Output Swing | ±16 V (32 VPP) min @ ±18 V, RL ≥ 600 Ω - delivers full-rail dynamic range into standard line-level loads without clipping. |
| Slew Rate | 13 V/μs typ (CC = 0 pF) - ensures faithful reproduction of fast transients in pulse amplification and DAC output buffering. |
| CMRR | 100 dB typ - rejects power supply and EMI-induced common-mode interference in unshielded industrial wiring. |
| Supply Range | ±3 V to ±20 V - accommodates legacy ±15 V rails and modern low-voltage ±5 V systems without redesign. |
| Operating Temp | –40°C to +85°C - qualified for under-hood automotive sensors, factory-floor PLC modules, and outdoor medical equipment. |
Pinout & Package
SA5534D is housed in an 8-pin SOIC (D) package (6.20 mm × 5.30 mm body size), RoHS-compliant, with moisture sensitivity level (MSL) Level-2-260°C-1 year.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BALANCE (Pin 1) | Offset null adjustment input | Connects to one end of external potentiometer for fine-tuning input offset voltage to <4 mV over temperature. |
| IN− (Pin 2) | Inverting input | Differential input node accepting feedback signals; protected by internal clamping diodes to rails. |
| IN+ (Pin 3) | Noninverting input | High-impedance (≥30 kΩ) input for reference or signal source; sensitive to layout-induced noise. |
| VCC− (Pin 4) | Negative supply rail | Must be decoupled with 0.1 μF ceramic capacitor placed ≤2 mm from pin to minimize PSRR degradation. |
| COMP (Pin 5) | Compensation output | Provides access to internal compensation node; used with COMP/BAL to set dominant pole for stability at target gain. |
| OUT (Pin 6) | Amplified output | Capable of driving 600 Ω loads with <0.002% THD+N; limited to ±32 VPP swing at ±18 V supplies. |
| VCC+ (Pin 7) | Positive supply rail | Accepts up to +20 V; requires local 0.1 μF bypass to ground to suppress supply-induced distortion. |
| COMP/BAL (Pin 8) | Shared compensation/offset node | Configurable as second offset null terminal (with BALANCE) or as frequency compensation input (with COMP). |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise architecture | 3.5 nV/√Hz input voltage noise enables sub-10 μV RMS noise floors in 20 kHz audio bands with proper PCB layout. |
| External offset nulling | Dual-pin (BALANCE + COMP/BAL) interface allows <1 mV residual offset after calibration - critical for DC-coupled medical amplifiers. |
| Gain ≥3 internal compensation | Stable at unity gain only when external capacitor (e.g., 22 pF) bridges COMP and COMP/BAL - prevents oscillation in high-Z sensor interfaces. |
| Robust output drive | Delivers ≥38 mA short-circuit current and sustains ±16 V swing into 600 Ω - eliminates need for external buffer stages in line-driver designs. |
| Wide supply flexibility | Operates from ±3 V (6 V total) to ±20 V (40 V total) - supports battery-powered portable gear and industrial ±15 V legacy systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1611AIDR | FET-input (0.2 pA IB), lower noise (1.1 nV/√Hz), but narrower supply range (±2.25 V to ±18 V) and no external compensation pins. | Better for ultra-high-Z pH sensors or piezoelectric transducers; unsuitable where external frequency tuning or offset nulling is required. | Choose OPA1611AIDR only if input bias current <1 pA is mandatory and external compensation is unnecessary. |
| NE5534DR | Same core architecture but rated for 0°C to +70°C; identical pinout, noise (3.5 nV/√Hz), and bandwidth (10 MHz); lower cost. | Valid for commercial-grade audio gear and non-automotive industrial controls where ambient temperature stays within 0–70°C. | Select NE5534DR when extended temperature range is not required - reduces BOM cost without sacrificing performance. |
Compared with SA5534D, OPA1611AIDR offers superior input impedance and lower voltage noise but forfeits offset nulling and compensation flexibility, while NE5534DR matches all electrical specs except temperature range - making it a direct drop-in for non-extended-temp applications.

FAQ
What is the operating temperature range of the SA5534D?
The SA5534D is specified for operation from –40°C to +85°C, making it suitable for industrial control cabinets, automotive under-hood modules, and portable medical devices exposed to wide ambient variations. This extended range exceeds the 0°C to +70°C rating of the NE5534D variant and is validated per TI's SLOS070D datasheet Section 7.3.
Does the SA5534D require external compensation for unity-gain stability?
Yes - the SA5534D is internally compensated for stable operation only at closed-loop gains ≥3. For unity-gain or gain-of-two configurations, an external capacitor (e.g., 22 pF) must be connected between COMP (Pin 5) and COMP/BAL (Pin 8) to ensure phase margin >45° and prevent oscillation, as detailed in Figure 10 and Section 8.3.5 of the SA5534D datasheet.
How is offset voltage adjusted on the SA5534D?
Offset voltage on the SA5534D is trimmed using a 10-kΩ potentiometer connected between BALANCE (Pin 1) and COMP/BAL (Pin 8), with the wiper grounded. Adjusting this potentiometer changes the current balance in the input differential pair, reducing input offset voltage to <1 mV. This method is confirmed in Section 9.1 and Figure 10 of the official TI datasheet.
What is the maximum supply voltage the SA5534D can withstand?
The SA5534D has an absolute maximum supply voltage of ±22 V (44 V total), but recommended operating conditions specify ±3 V to ±20 V. Exceeding ±22 V risks permanent damage, per Absolute Maximum Ratings Table 7.1 in the TI SLOS070D datasheet. For reliable long-term operation, stay within ±15 V unless transient headroom is explicitly required.
Is the SA5534D pin-compatible with other 5534-series op-amps?
Yes - the SA5534D shares identical SOIC-8 pinout and electrical behavior with NE5534D, SA5534ADR, and NE5534ADR. All variants use Pins 1–8 for BALANCE, IN−, IN+, VCC−, COMP, OUT, VCC+, and COMP/BAL respectively. Mechanical compatibility is confirmed in TI's Package Option Addendum, where SA5534D and NE5534D both map to SOIC (D) | 8.
