Product details

Overview

TS514IN 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 integrates internal frequency/phase compensation for stable unity-gain operation and delivers high channel separation (120 dB) and low THD (0.03%)-used in telecom active filters and professional audio signal conditioning.

For engineers reviewing the TS514IN datasheet, TS514IN pinout, TS514IN application, or TS514IN equivalent, key selection criteria include input offset drift (5 µV/°C), supply current per op-amp (0.6 mA typ), ESD robustness (2 kV HBM), and common-mode rejection (90 dB) across -40°C to +125°C industrial temperature range.

Technical Context

The TS514IN employs internally compensated voltage-feedback architecture with rail-to-rail input common-mode range (V_DD+0.8 to V_CC−1.5 V) and operates stably from ±4 V to ±15 V supplies. Its high slew rate (1.5 V/µs) and low noise (8 nV/√Hz at 1 kHz) support wideband analog signal processing without external compensation.

Designed for multi-channel precision tasks, it maintains >90 dB CMRR and SVRR over full temperature and supply range, while channel separation of 120 dB enables independent signal paths in dense PCB layouts-critical for active filter banks and instrumentation front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Input offset voltage	500 µV max - ensures <0.01% gain error in 10 V full-scale precision amplification
Gain bandwidth product	3 MHz - supports stable closed-loop gain up to 30 at 100 kHz for anti-aliasing filters
Slew rate	1.5 V/µs - enables clean 10 Vpp output at 100 kHz without distortion
Channel separation	120 dB - prevents crosstalk between adjacent op-amps in quad configurations
ESD protection	2 kV HBM - meets IEC 61000-4-2 Level 2 for board-level handling reliability
Supply current per op-amp	0.6 mA typ - allows four channels to operate under 2.5 mA total at ±15 V
Output short-circuit current	23 mA - drives 600 Ω loads directly without external current limiting

Pinout & Package

TS514IN is housed in a 14-pin SOIC (SO-14) plastic micropackage with 1.27 mm pitch, 8.75 mm × 4.0 mm body, and 1.75 mm height. Thermal resistance is 103 °C/W (junction-to-ambient) and 31 °C/W (junction-to-case).

Pin/Terminal	Circuit Role	Design Meaning
1	Output A	Amplified output of first op-amp; capable of ±13 V swing into 2 kΩ
2	Inverting input A	Differential input node for channel A; supports common-mode range to V_CC−1.5 V
3	Non-inverting input A	Differential input node for channel A; matched bias current (150 nA typ)
4	V_EE (negative supply)	Ground reference for dual-supply operation; accepts −18 V absolute max
5	Non-inverting input B	Input for second op-amp; electrically isolated with 120 dB channel separation
6	Inverting input B	Inverting node for channel B; identical DC specs to channel A
7	Output B	Second independent output; same AC/DC performance as pin 1
8	Output C	Third op-amp output; shares supply rails and thermal path with other channels
9	Inverting input C	Input for third op-amp; low 5 µV/°C offset drift ensures stability over temperature
10	Non-inverting input C	Positive input for channel C; high 1 MΩ input resistance minimizes loading
11	V_CC (positive supply)	Positive rail connection; supports 6–30 V single or ±15 V dual supply
12	Non-inverting input D	Fourth op-amp non-inverting input; matched to other inputs for common-mode rejection
13	Inverting input D	Fourth op-amp inverting input; low 20 nA offset current reduces DC error accumulation
14	Output D	Final output channel; fully specified for THD (0.03%), noise (8 nV/√Hz), and SR (1.5 V/µs)

Key Features

Feature	Design Value
Internal phase compensation	Enables stable unity-gain follower configuration without external components
High channel separation (120 dB)	Prevents inter-channel interference in multi-stage active filter designs

Short-circuit protection	Allows indefinite output shorting to either rail without damage or latch-up
Low THD (0.03% at 1 kHz)	Preserves signal fidelity in audio preamplifier and sensor signal chain stages

Applications

IC Role / Device Role / Timing Role: Quad op-amp implements two 2-pole Sallen-Key stages with shared bias and decoupling.

Use Value: 120 dB channel separation prevents stage coupling; 3 MHz GBP ensures flat response to 100 kHz.

Use Scenario: Balanced microphone preamplifier with gain switching and phantom power.

IC Role / Device Role / Timing Role: One op-amp buffers mic input, two configure instrumentation amp, fourth drives output stage.

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 V_io (6 mV max), lower GBP (3 MHz typ but no min spec), no guaranteed 125°C operation	Not rated for extended temperature; higher noise (18 nV/√Hz) limits low-level sensor use	Select only for cost-sensitive commercial-grade designs where 500 µV offset is not required
OP4177ARUZ	Lower V_io (60 µV max), higher price, TSSOP-14 package, no short-circuit protection	Superior DC precision but lacks fault tolerance; unsuitable for outputs driving cables or connectors	Choose when ultra-low offset and drift dominate; avoid where output shorts are possible

Compared with TL074CDR and OP4177ARUZ, TS514IN uniquely balances industrial temperature range, short-circuit resilience, and 500 µV offset-making it optimal for telecom and medical signal chains where reliability and moderate precision coexist.

FAQ

What is the maximum supply voltage for TS514IN?

The TS514IN supports absolute maximum supply voltages of ±18 V, with recommended operating range from ±4 V to ±15 V. Operation at ±15 V delivers full-rated performance including ±13 V output swing and 3 MHz GBP. Exceeding ±18 V risks permanent damage per absolute maximum ratings table.

Does TS514IN require external compensation capacitors?

No, TS514IN features internal frequency and phase compensation optimized for unity-gain stable operation. The datasheet confirms stable voltage-follower behavior without external components across all supply voltages and temperatures. Adding external compensation may degrade bandwidth or cause instability.

How does TS514IN handle output short circuits?

TS514IN includes built-in short-circuit protection that limits output current to 23 mA and prevents thermal runaway or device failure during indefinite shorting to either supply rail. This feature is validated across −40°C to +125°C and eliminates need for external current-limiting resistors in most applications.

Is TS514IN pin-compatible with other quad op-amps in SO-14?

TS514IN follows standard SO-14 quad op-amp pinout (pin 1 = OUT A, pin 4 = V_EE, pin 7 = OUT B, etc.), matching industry convention used by TL074, LM324, and OP4177. However, electrical differences-especially input bias current, offset voltage, and supply range-require circuit validation before drop-in replacement.
