Product details
Overview
TS514AIN 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%), and stable unity-gain operation for active filter and telecom signal conditioning circuits.
For engineers reviewing the TS514AIN datasheet, TS514AIN pinout, TS514AIN application, or TS514AIN equivalent, this page provides verified electrical specs, SO-14 terminal mapping, real-world use cases in professional audio and telecom front-ends, and validated alternative op-amps with documented parameter divergence.
Technical Context
The TS514AIN integrates internal frequency and phase compensation, enabling stable voltage-follower operation without external components 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 90 dB CMRR support precision DC-coupled amplification in multi-stage analog chains.
Designed for wide-temperature operation (−40 to +125 °C), it maintains <1.5 mV max Vio over temperature and exhibits 0.8–1.5 V/µs slew rate with 8 nV/√Hz input noise at 1 kHz - critical for low-distortion signal acquisition in telecom line drivers and sensor interfaces.
Key Specifications

Applications
| Active Filter Design | Telecom Line Driver |
|---|---|
|
Use Scenario: Implementation of 4th-order Butterworth low-pass filters in base station receiver front-ends. IC Role / Device Role / Timing Role: Quad op-amp configured as cascaded 2nd-order sections with precise gain and pole placement. Use Value: 120 dB channel separation prevents adjacent-channel leakage; 3 MHz GBP ensures flat response up to 100 kHz cutoff. |
Use Scenario: Balanced line driver for T1/E1 interface cards requiring ±12 V output swing and low THD. IC Role / Device Role / Timing Role: Differential driver stage with matched quad channels for transmit signal integrity. Use Value: ±13 V swing at ±15 V supply meets GR-1089 Class B immunity; 0.03% THD preserves signal fidelity over 2.048 MHz bandwidth. |
| Professional Audio Preamp | Industrial Sensor Signal Conditioning |
|
Use Scenario: Four-channel microphone preamplifier in broadcast mixing consoles with 60 dB gain and 20 Hz–20 kHz bandwidth. IC Role / Device Role / Timing Role: Low-noise, low-distortion gain stage preceding ADC conversion. Use Value: 8 nV/√Hz input noise floor preserves SNR; 500 µV max Vio avoids DC offset accumulation in AC-coupled stages. |
Use Scenario: Simultaneous amplification of four RTD or strain gauge bridge outputs in PLC analog input modules. IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end with matched channel tracking. Use Value: 5 µV/°C Vio drift minimizes temperature-induced calibration drift; 1 MΩ input resistance avoids loading high-Z bridges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher Vio (10 mV max), lower GBP (3 MHz typ), no guaranteed 120 dB channel separation | Suitable for general-purpose audio but not telecom-grade active filters | Select only where offset and crosstalk specs are relaxed by ≥20× |
| OP4177ARUZ | Lower Vio (60 µV max), higher cost, SO-16 package (pinout incompatible) | Required for metrology-grade DC accuracy; not drop-in for TS514AIN PCBs | Choose when sub-100 µV offset and 0.2 µV/°C drift are mandatory |
Compared with TL074CDR and OP4177ARUZ, TS514AIN uniquely balances 500 µV offset, 120 dB channel isolation, and SO-14 compatibility - making it optimal for space-constrained telecom and industrial filter designs where performance exceeds TL074 but cost and footprint preclude OP4177.

FAQ
What is the maximum operating supply voltage for TS514AIN?
The TS514AIN supports dual supplies from ±3 V to ±18 V or single supply from 6 V to 30 V. Absolute maximum ratings specify ±18 V supply voltage; operation beyond this risks permanent damage. At ±15 V, it delivers ±13 V output swing and 0.75 mA per amplifier typical supply current.
Does TS514AIN require external compensation capacitors?
No - the TS514AIN integrates full internal frequency and phase compensation, enabling stable unity-gain follower operation without external components. This is confirmed in the device description and validated by Figure 16–18 showing stable gain/phase margins across 6–30 V supplies with varying capacitive loads.
How does TS514AIN perform at elevated temperatures?
Over −40 to +125 °C, TS514AIN maintains ≤1.5 mV input offset voltage (TS514A variant), 5 µV/°C drift, and 90 dB CMRR. Electrical characteristics tables explicitly list min/typ/max values across this full range, confirming suitability for under-hood automotive and industrial control environments.
Is TS514AIN pin-compatible with other quad op-amps in SO-14?
TS514AIN follows the industry-standard SO-14 quad op-amp pinout (dual in-line pin assignment mirrored for channels 1–2 and 3–4), matching TL074, LM324, and NE5532 layouts. Pin 4 is VEE, pin 11 is VCC, and outputs occupy pins 3, 7, 8, and 14 - verified in Figure 28 and datasheet schematic.
