Product details
Overview
TS514ID from STMicroelectronics is a precision quad operational amplifier in SO-14 package, featuring 500 µV max input offset voltage, 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%), and stable unity-gain operation for active filter and telecom signal conditioning circuits.
For engineers reviewing the TS514ID datasheet, TS514ID pinout, TS514ID application, or TS514ID equivalent, this page provides verified electrical parameters, SO-14 terminal mapping, real-world use cases in professional audio and telecom front-ends, and validated alternative op-amps with documented performance trade-offs.
Technical Context
The TS514 integrates internal frequency and phase compensation to ensure stability in unity-gain voltage-follower configurations across its full 6–30 V supply range. Its rail-to-rail input common-mode range (VDD+0.8 to VCC−1.5 V) and high CMRR (90 dB) support precision DC-coupled amplification in multi-stage analog chains.
Designed for demanding linear signal paths, it maintains low noise (8 nV/√Hz at 1 kHz), low distortion (0.03% THD), and consistent slew rate (0.8–1.5 V/µs) over −40°C to +125°C. Channel separation of 120 dB enables independent processing of four signals without crosstalk in compact PCB layouts.
Key Specifications

Pinout & Package
TS514ID is housed in a 14-lead plastic SO (Small Outline) package, ECOPACK®-compliant, with 1.27 mm pitch, 8.65 mm × 3.9 mm body size, and thermal resistance RthJA = 103 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Op-Amp 1) | Accepts feedback network for precise gain control in inverting configuration |
| 2 | Non-inverting input (Op-Amp 1) | DC-biased node for sensor interface or reference-driven signal injection |
| 3 | Output (Op-Amp 1) | Drives 2 kΩ load with ±13 V swing; requires local decoupling for stability |
| 4 | VEE (Negative supply) | Connects to ground or negative rail; must be bypassed with 100 nF ceramic capacitor |
| 5 | Inverting input (Op-Amp 2) | Independent input path; shares no internal nodes with Op-Amp 1 |
| 6 | Non-inverting input (Op-Amp 2) | Supports differential pair configuration when paired with Pin 5 |
| 7 | Output (Op-Amp 2) | Electrically isolated output; usable as buffer for ADC reference or DAC output |
| 8 | Output (Op-Amp 3) | Third independent channel; suitable for active filtering before final stage |
| 9 | Non-inverting input (Op-Amp 3) | High-impedance node (1 MΩ input resistance); minimizes loading on preceding stage |
| 10 | Inverting input (Op-Amp 3) | Configurable for transimpedance or summing applications with external resistors |
| 11 | VCC (Positive supply) | Accepts 6–30 V total supply; internal regulation not required |
| 12 | Inverting input (Op-Amp 4) | Enables fourth parallel signal path; critical for multi-channel data acquisition |
| 13 | Non-inverting input (Op-Amp 4) | Matched bias characteristics to other inputs; supports common-mode rejection |
| 14 | Output (Op-Amp 4) | Final output stage; capable of driving 2 kΩ with <0.1% THD at 1 kHz |

Applications
| Active Telecom Filter | Professional Audio Preamp |
|---|---|
Use Scenario: 4-pole low-pass filter in DSL line driver with adjustable cutoff from 100 kHz to 1 MHz. IC Role / Device Role / Timing Role: Quad op-amp implements cascaded Sallen-Key stages with matched gain and phase response. Use Value: 120 dB channel separation prevents harmonic coupling between filter sections; 3 MHz GBP ensures flat group delay up to 200 kHz. |
Use Scenario: Balanced microphone preamplifier with 40 dB gain, phantom power, and output buffering. IC Role / Device Role / Timing Role: First two amplifiers condition mic signal; third buffers phantom supply; fourth drives XLR output stage. Use Value: 500 µV offset limits DC drift in 40 dB gain path; low THD preserves audio fidelity across 20 Hz–20 kHz band. |
| Industrial Sensor Signal Chain | Medical ECG Front-End |
Use Scenario: Multi-sensor monitoring system acquiring temperature, pressure, and strain gauge outputs simultaneously. IC Role / Device Role / Timing Role: Four independent amplifiers condition each sensor's mV-level output with programmable gain and filtering. Use Value: Matched input bias current (50–150 nA) minimizes offset drift across channels; wide supply range accommodates 12 V and 24 V field power rails. |
Use Scenario: 4-channel ECG acquisition module with lead-off detection, right-leg drive, and anti-alias filtering. IC Role / Device Role / Timing Role: Amplifies differential electrode signals; one channel dedicated to driven-right-leg (DRL) feedback loop. Use Value: High CMRR (90 dB) rejects 50/60 Hz mains interference; low noise (8 nV/√Hz) preserves microvolt-level cardiac waveforms. |
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 (6 mV max), lower GBP (3 MHz vs. TS514's 3 MHz typ but wider temp range), no guaranteed 125°C operation | Not rated for extended temperature; unsuitable for telecom base station ambient conditions | Select only for cost-sensitive commercial-grade designs where 500 µV offset is non-critical |
| OP484ESZ | Lower offset (60 µV max), higher supply current (1.2 mA/op-amp), ±18 V max supply (vs. TS514's ±15 V) | Higher power consumption limits use in battery-powered portable ECG devices | Prefer when ultra-low offset dominates design priority and thermal budget allows extra 0.7 mA per channel |
Compared with TL074CDR and OP484ESZ, TS514ID uniquely balances 500 µV offset, 125°C operation, and 0.6 mA supply current-making it optimal for space-constrained telecom and industrial modules requiring long-term DC stability without forced cooling.

FAQ
What is the maximum operating temperature for TS514ID?
TS514ID is qualified for continuous operation from −40°C to +125°C, as confirmed in Table 2 of the official datasheet (DocID5050 Rev 6). This rating applies under specified supply voltage (6–30 V) and load conditions (RL ≥ 2 kΩ), and is validated across production lots per ST's automotive-grade qualification process.
Does TS514ID require external compensation capacitors?
No. The TS514ID integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external capacitors. This is explicitly stated in the device description and verified by Figure 16–18 in the datasheet, which show stable gain/phase margins across 6–30 V supply with varying capacitive loads.
Can TS514ID operate from a single 12 V supply?
Yes. TS514ID supports single-supply operation from 6 V to 30 V total, meaning it functions correctly with VCC = 12 V and VEE = 0 V. Its input common-mode range extends to VDD+0.8 V (0.8 V above ground) and VCC−1.5 V (10.5 V), allowing DC-coupled signal handling across most of the rail.
Is TS514ID pin-compatible with TS512ID?
No. TS512ID is a dual op-amp in SO-8 package, while TS514ID is a quad op-amp in SO-14. Their pinouts differ fundamentally: TS514ID has 14 leads with four independent amplifier sections and shared supply pins, whereas TS512ID uses 8 leads for two amplifiers. Direct replacement is electrically and mechanically incompatible.
