Product details
Overview
TS514AID from STMicroelectronics is a precision quad operational amplifier in SO-14 package, featuring 500 µV max input offset voltage, 1.8–3 MHz gain bandwidth product, and ±13 V output swing at ±15 V supply. It delivers high channel separation (120 dB), low THD (0.03% typ), and operates across –40 °C to +125 °C for telecom active filters and professional audio signal conditioning.
For engineers reviewing the TS514AID datasheet, TS514AID pinout, TS514AID application, or TS514AID equivalent, key selection criteria include input offset drift (5 µV/°C), supply current per op-amp (0.6 mA typ), common-mode rejection (90 dB), and ESD robustness (2 kV HBM) in high-channel-density analog front-ends.
Technical Context
The TS514AID integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external components. Its rail-to-rail input stage supports common-mode range from VDD +0.8 V to VCC –1.5 V, and its high gain-bandwidth enables accurate wideband filtering up to 3 MHz.
Designed for multi-channel precision signal paths, it maintains consistent DC accuracy (input offset ≤1.5 mV over temperature) and AC performance (slew rate 0.8–1.5 V/µs) across full supply range (6–30 V). Channel separation of 120 dB at 1 kHz ensures minimal crosstalk in simultaneous-sampling systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | ≤1.5 mV over –40 to +125 °C - ensures <±2 mV error in DC-coupled sensor amplifiers without trimming |
| Gain bandwidth product | 1.8–3 MHz - supports stable 20× closed-loop gain up to ~150 kHz with phase margin >45° |
| Slew rate | 0.8–1.5 V/µs - enables clean 2 VPP output at 1 kHz with <0.1% THD |
| Channel separation | 120 dB at 1 kHz - prevents audible crosstalk in 4-channel audio line drivers |
| Supply current per op-amp | 0.6 mA typical at ±15 V - allows four channels to operate within 2.4 mA total quiescent budget |
| Common-mode rejection | 90 dB - rejects >30 kΩ imbalance-induced error in differential input stages |
| ESD rating (HBM) | 2 kV - meets IEC 61000-4-2 Level 2 for board-level handling without added protection |
Pinout & Package
TS514AID is housed in a 14-pin SOIC (SO-14) plastic micropackage with standard 1.27 mm pitch, 8.65 mm × 3.9 mm body, and 1.75 mm max height. Thermal resistance is 103 °C/W (junction-to-ambient) and 31 °C/W (junction-to-case).

| 6 | Inverting input (Op-Amp B) | Configurable for B-channel transimpedance or difference amplification |
| 7 | Output (Op-Amp B) | Electrically isolated output path; 120 dB separation from A-channel output |
| 8 | Output (Op-Amp C) | Third independent output; identical AC/DC specs as A/B channels |
| 9 | Inverting input (Op-Amp C) | Supports cascaded filter stages without inter-channel loading |
| 10 | Non-inverting input (Op-Amp C) | Enables parallel-input configurations with matched bias current (50–300 nA) |
| 11 | VCC (positive supply) | Accepts 6–30 V single or ±15 V dual supply; regulates internal bias independently |
| 12 | Non-inverting input (Op-Amp D) | Fourth channel input; validated for 125 °C operation with <1.5 mV offset shift |
| 13 | Inverting input (Op-Amp D) | Allows D-channel to serve as precision reference buffer with 500 µV max initial offset |
| 14 | Output (Op-Amp D) | Final channel output; maintains 0.8 V/µs min slew rate even at 125 °C junction temp |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher input offset (3 mV max), lower GBP (3 MHz typ but only at 25 °C), no guaranteed 125 °C operation | Not qualified for extended temperature industrial use; higher noise (18 nV/√Hz vs. 8 nV/√Hz) | Lower-cost option where ambient temperature stays <85 °C and offset drift <10 µV/°C is acceptable |
| OP4177ARUZ | Lower offset (60 µV max), lower noise (7.9 nV/√Hz), but higher supply current (500 µA per amp vs. 600 µA) and SO-16 package | Requires PCB redesign for SO-16; superior for <16-bit precision but over-specified for 12–14-bit systems | Preferred when sub-100 µV offset and <0.001% THD are mandatory, despite 2× cost and larger footprint |
Compared with TL074CDR and OP4177ARUZ, TS514AID offers the optimal balance of 125 °C operation, 500 µV offset, SO-14 compatibility, and 0.6 mA per amplifier-making it ideal for cost-sensitive, thermally demanding, multi-channel analog systems where moderate precision suffices.

FAQ
What is the maximum operating temperature for TS514AID?
The TS514AID is rated for continuous operation from –40 °C to +125 °C ambient temperature, with all electrical specifications guaranteed across this full range. Its SO-14 package has a thermal resistance of 103 °C/W (junction-to-ambient), allowing safe operation at 125 °C with appropriate PCB copper area and airflow.
Does TS514AID require external compensation capacitors?
No. The TS514AID integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external components. This is confirmed in the device description and verified by Figure 16–21 in the datasheet showing stable gain/phase margins across 6–30 V supplies and capacitive loads up to 100 pF.
How does TS514AID compare to TS514ID in performance?
The TS514AID guarantees tighter input offset voltage (≤1.5 mV over temperature vs. ≤2.5 mV for TS514ID) and improved offset drift (5 µV/°C vs. unspecified for ID grade). Both share identical pinout, package, and AC specs, but the 'A' grade is selected for higher DC precision in critical measurement applications.
Can TS514AID drive 600 Ω loads at ±12 V output swing?
Yes. At ±15 V supply, TS514AID delivers ±13 V output swing into 2 kΩ (Table 3), and its 23 mA short-circuit current supports ≥±12 V into 600 Ω (requiring ≤20 mA). Figure 12–15 confirm linear output current capability up to ±15 V at 30 V total supply, validating 600 Ω drive capability.
