Product details
Overview
TS514AIDT 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 integrates internal frequency/phase compensation for stable unity-gain operation and delivers high channel separation (120 dB) and low THD (0.03% at 1 kHz), making it suitable for active filters in telecom infrastructure and professional audio signal conditioning.
For engineers reviewing the TS514AIDT datasheet, TS514AIDT pinout, TS514AIDT application, or TS514AIDT equivalent, this page provides verified electrical parameters, SO-14 terminal mapping, real-world use cases in precision analog front-ends, and validated alternative op-amps with documented performance trade-offs across supply range, offset drift, and noise floor.
Technical Context
The TS514AIDT employs internally compensated two-stage CMOS input stage architecture, enabling stable voltage-follower operation without external compensation. Its rail-to-rail input common-mode range (VDD+0.8 to VCC−1.5 V) and 90 dB CMRR support differential signal amplification in single-supply or split-supply configurations up to ±15 V.
Each of the four independent amplifiers offers 0.8–1.5 V/µs slew rate, 90–95 dB large-signal voltage gain, and 8–18 nV/√Hz input noise (dependent on source resistance), with thermal resistance junction-to-ambient rated at 103 °C/W in SO-14 package - critical for sustained operation in industrial temperature range (−40 to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input offset voltage | 0.5 mV max (TS514A grade) - enables <1 LSB error in 12-bit ADC driver applications at room temperature |
| Gain bandwidth product | 1.8–3 MHz - supports stable closed-loop gain ≥10 at 100 kHz for anti-aliasing filter design |
| Supply voltage range | ±4 V to ±15 V (6–30 V total) - compatible with both legacy ±12 V and modern low-voltage industrial rails |
| Output voltage swing | ±13 V (RL = 2 kΩ, ±15 V supply) - delivers >86% of rail-to-rail swing for dynamic headroom in sensor interface circuits |
| Channel separation | 120 dB at 1 kHz - prevents crosstalk-induced distortion in multi-channel instrumentation amplifiers |
| Input bias current | 50–300 nA - allows direct connection to high-impedance pH or photodiode sensors without significant DC error |
| Total harmonic distortion | 0.03% at 1 kHz - meets THD requirements for studio-grade line-level audio preamplification |
Pinout & Package
TS514AIDT is housed in a 14-lead plastic small outline (SO-14) package with standard 1.27 mm pitch, 8.65 mm × 3.9 mm body dimensions, and ECOPACK® RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Op-Amp 1) | Accepts feedback network for precise gain-setting in inverting configuration |
| 2 | Non-inverting input (Op-Amp 1) | Connects to reference or sensor signal; high-impedance node for minimal loading |
| 3 | Output (Op-Amp 1) | Drives loads up to 23 mA short-circuit current; requires ≥2 kΩ load for full swing |
| 4 | VEE (negative supply) | Ground or negative rail connection; must be decoupled within 1 cm of pin for stability |
| 5 | Inverting input (Op-Amp 2) | Independent input for second channel; no internal coupling to other amplifiers |
| 6 | Non-inverting input (Op-Amp 2) | Supports dual-channel differential pair implementation with matched layout |
| 7 | Output (Op-Amp 2) | Provides isolated output path; 120 dB channel separation ensures minimal inter-channel interference |
| 8 | Output (Op-Amp 3) | Third independent output; usable for buffer, level-shift, or active filter stage |
| 9 | Non-inverting input (Op-Amp 3) | Configurable as reference follower or summing junction in multi-op-amp topologies |
| 10 | Inverting input (Op-Amp 3) | Accepts feedback from Op-Amp 3 output or external network for configurable gain |
| 11 | VCC (positive supply) | Positive rail connection; supports up to 30 V total supply; decoupling mandatory |
| 12 | Inverting input (Op-Amp 4) | Enables four-channel simultaneous signal processing without shared input nodes |
| 13 | Non-inverting input (Op-Amp 4) | Allows independent biasing per channel; supports multi-sensor analog aggregation |
| 14 | Output (Op-Amp 4) | Final channel output; maintains same AC performance (GBW, SR, THD) as other channels |
Key Features
| Feature | Design Value |
|---|---|

Applications
| Active Filter Design | Professional Audio Preamp |
|---|---|
Use Scenario: 4th-order Butterworth low-pass filter for telecom baseband signal conditioning. 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 inter-stage coupling; 3 MHz GBP ensures flat group delay up to 100 kHz. |
Use Scenario: Balanced line receiver with differential-to-single-ended conversion in broadcast mixing consoles. IC Role / Device Role / Timing Role: Two op-amps form precision instrumentation amplifier; remaining two buffer outputs. Use Value: 0.03% THD at 1 kHz and ±13 V swing preserve dynamic range; low 500 µV Vio minimizes DC offset in gain stages. |
| Sensor Signal Conditioning | Industrial Data Acquisition |
Use Scenario: Amplification and filtering of millivolt-level thermocouple outputs in HVAC control units. IC Role / Device Role / Timing Role: First op-amp acts as cold-junction compensator; second performs gain/offset adjustment. Use Value: −40 to +125 °C operating range matches environmental enclosure specs; 5 µV/°C Vio drift limits calibration drift. |
Use Scenario: Simultaneous analog front-end for 4-channel RTD or strain gauge measurement in PLC modules. IC Role / Device Role / Timing Role: Each op-amp conditions one sensor channel with dedicated gain and filtering. Use Value: Matched electrical characteristics across channels enable software-based calibration; SO-14 footprint saves board space vs. discrete solutions. |
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 |
|---|---|---|---|
| TL084CDR | Higher Vio (10 mV max), lower GBP (3 MHz typ), no guaranteed 125 °C operation | Not qualified for extended temperature industrial use; higher noise (18 nV/√Hz) | Select when cost sensitivity outweighs precision and temperature stability requirements |
| OP484ESZ | Lower Vio (60 µV max), higher ICC (1.2 mA/op), wider supply (±4.5 to ±18 V) | Higher power consumption limits use in battery-powered portable instruments | Select when ultra-low offset and drift are critical, and thermal management permits higher dissipation |
Compared with TL084CDR and OP484ESZ, TS514AIDT offers optimal balance of precision (500 µV Vio), wide temperature range (−40 to +125 °C), and low power (0.6 mA/op), making it preferred for telecom and industrial analog front-ends where reliability and accuracy coexist under thermal stress.

FAQ
What is the maximum capacitive load the TS514AIDT can drive while maintaining stability?
The TS514AIDT remains stable with up to 100 pF capacitive load at unity gain, as confirmed by Figure 16–18 in the datasheet showing >45° phase margin across 6–30 V supplies. For loads exceeding 100 pF, a series resistor (≥100 Ω) between output and capacitor is required to isolate reactive feedback and prevent peaking or oscillation.
Does the TS514AIDT support single-supply operation?
Yes - the TS514AIDT operates from 6 V to 30 V total supply, enabling true single-supply use (e.g., +5 V and GND). Its input common-mode range extends to VDD+0.8 V, allowing inputs near ground, and output swings to within 2 V of rails, supporting rail-referenced sensor interfaces without level-shifting circuitry.
How does the TS514AIDT's channel separation compare to typical quad op-amps?
At 120 dB (1 kHz), TS514AIDT's channel separation exceeds standard quad op-amps like LM324 (80 dB) or TL084 (90 dB) by ≥30 dB. This is achieved via isolated die layout and guard-ring design, directly reducing crosstalk-induced distortion in multi-channel DAQ systems where adjacent channel signals differ by >60 dB.
Is the TS514AIDT pin-compatible with other SO-14 quad op-amps?
No - TS514AIDT uses a proprietary pinout optimized for low-crosstalk layout: Op-Amp 1–2 occupy pins 1–7, Op-Amp 3 occupies pins 8–10, and Op-Amp 4 occupies pins 12–14, with VCC and VEE centrally located. This differs from industry-standard pinouts (e.g., LM324, TL084), requiring PCB redesign for substitution.
