Product details
Overview
TS514IDT from STMicroelectronics is a precision quad operational amplifier in SO-14 package, designed for high-stability analog signal conditioning in professional audio and telecom infrastructure. It delivers 500 µV max input offset voltage, 1.8–3 MHz gain bandwidth product, ±13 V output swing (±15 V supply), 120 dB channel separation, and operates across –40 °C to +125 °C for active filter and instrumentation amplifier stages.
For engineers reviewing the TS514IDT datasheet, TS514IDT pinout, TS514IDT application, or TS514IDT equivalent, key selection criteria include low distortion (0.03% THD), high CMRR (90 dB), rail-to-rail input common-mode range (VDD+0.8 to VCC–1.5 V), thermal robustness (RthJA = 103 °C/W), and ESD tolerance (2 kV HBM).
Technical Context
The TS514 integrates internal frequency and phase compensation, enabling stable unity-gain voltage-follower operation without external components. Its quad architecture supports independent biasing per channel with matched AC/DC characteristics over full supply range (±18 V absolute max, 6–30 V operating).
Electrical stability is maintained across temperature (–40 °C to +125 °C) and supply voltage via tightly controlled input offset drift (5 µV/°C) and supply current variation (0.5–0.75 mA per op-amp). Channel separation of 120 dB at 1 kHz ensures minimal crosstalk in multi-channel filtering and summing applications.
Key Specifications

|---|---|
| Input offset voltage | 500 µV max - enables DC-coupled precision amplification with ≤0.005% error in 10 V full-scale systems |
| Gain bandwidth product | 1.8–3 MHz - supports stable closed-loop gain ≥10 up to 300 kHz for anti-aliasing and reconstruction filters |
| Output voltage swing | ±13 V (RL = 2 kΩ, ±15 V supply) - provides >86% rail utilization for dynamic headroom in line-driver stages |
| Channel separation | 120 dB at 1 kHz - suppresses inter-channel interference in stereo preamps and multi-path sensor signal chains |
| Supply current per channel | 0.5–0.75 mA - allows four-channel operation under 3 mA total, suitable for low-power telecom line cards |
| Common-mode rejection ratio | 90 dB - rejects power-supply ripple and shared-noise coupling in differential front-end configurations |
| THD | 0.03% at 1 kHz - preserves signal fidelity in professional audio mixing and broadcast signal processing |
Pinout & Package

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 GBW (3 MHz typ), no guaranteed 125 °C operation | Suitable for commercial-grade audio but not telecom or industrial environments requiring extended temperature range | Select when cost sensitivity outweighs precision and temperature stability requirements |
| OP4177ARUZ | Lower offset (60 µV max), higher price, TSSOP-14 package with smaller thermal pad area (RthJA = 125 °C/W) | Better for ultra-low-drift medical applications but less robust under sustained 125 °C ambient conditions | Prefer where sub-100 µV offset dominates over thermal reliability and supply current |
Compared with TL074CDR and OP4177ARUZ, TS514IDT offers optimal balance of precision (500 µV offset), thermal ruggedness (–40 to +125 °C), and quiescent power (0.6 mA/ch), making it ideal for space-constrained telecom line cards and industrial control modules requiring long-term calibration stability.

FAQ
What is the maximum capacitive load the TS514IDT can drive while maintaining stability?
The TS514IDT maintains phase margin >45° with up to 100 pF capacitive load at ±15 V supply and 2 kΩ resistive load, as confirmed by Figure 16–18 in the datasheet. For loads >100 pF, external series resistance (≥10 Ω) is recommended at the output to preserve stability in active filter and cable-driving applications.
Does the TS514IDT support single-supply operation?
Yes - the TS514IDT operates with single supplies from 6 V to 30 V. Its input common-mode range extends from VDD + 0.8 V to VCC – 1.5 V, allowing rail-to-rail input operation when biased near mid-supply. Output swing reaches within 2 V of each rail under 2 kΩ load.
How does the TS514IDT's channel separation compare to typical quad op-amps?
At 120 dB (1 kHz), TS514IDT's channel separation exceeds standard quad op-amps (typically 80–100 dB) by 20–40 dB. This is achieved through proprietary die layout and isolation trenches, directly reducing crosstalk in multi-channel active filters and stereo processing circuits.
Is the TS514IDT qualified for automotive applications?
No - TS514IDT is specified for industrial and telecom use (–40 °C to +125 °C), but lacks AEC-Q100 qualification. ST offers the TS514AIDT variant with enhanced screening for automotive-grade reliability, though both share identical electrical specs and SO-14 packaging.
