Product details

Overview

TS524IDT from STMicroelectronics is a precision low-noise quad operational amplifier designed for high-fidelity audio signal conditioning and sensor interface circuits. It delivers 950 µV max input offset voltage, 4.5 nV/√Hz input voltage noise, 15 MHz gain bandwidth product, 7 V/µs slew rate, and 0.002% THD at 20 Hz–20 kHz - enabling clean amplification in preamplifier and active filter stages.

For engineers reviewing the TS524IDT datasheet, TS524IDT pinout, TS524IDT application, or TS524IDT equivalent, key selection criteria include its rail-to-rail output swing capability (±13.5 V into 600 Ω), symmetrical ±29 mA source/sink current, and guaranteed operation from −40°C to +105°C across dual ±2.5 V to ±15 V supplies.

Technical Context

The TS524IDT integrates four independent high-performance op-amps on a single die with matched internal transistor pairs ensuring low ∆Vio drift (2 µV/°C) and high channel separation (120 dB). Its macromodel supports accurate SPICE simulation of transient response, distortion, and noise performance under real-world load conditions.

Designed for dual-supply operation, it features ±13 V common-mode input range and ±14.6 V output swing into 10 kΩ, with stable unity-gain compensation (55° phase margin, CL = 0 pF) and full-power bandwidth of 120 kHz at 27 Vpp output - critical for wide-dynamic-range analog front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Offset Voltage	Max 0.95 mV at T_A = 25°C; ensures ≤1.8 mV error over full −40°C to +105°C range for precision DC-coupled gain stages.
Gain Bandwidth Product	15 MHz typical; enables stable closed-loop gain ≥10 at 1.5 MHz or ≥100 at 150 kHz without peaking.
Slew Rate	7 V/µs typical; supports 20 kHz full-scale sine output up to 14 Vpp without slewing-induced distortion.
THD + Noise	0.002% at 3 V_rms, 20 Hz–20 kHz; meets Hi-Fi preamp line-level requirements with minimal harmonic corruption.
Output Short-Circuit Current	±29 mA sink/source; drives 600 Ω loads directly while maintaining linearity and thermal safety.
Common-Mode Rejection	Min 80 dB; rejects supply ripple and ground bounce in single-ended sensor interfaces.
Supply Voltage Range	±2.5 V to ±15 V; compatible with legacy ±12 V and modern ±5 V analog rails without level-shifting.

Pinout & Package

TS524IDT is supplied in a 14-pin plastic micropackage (SO14), compliant with JEDEC MS-012, with 1.27 mm pitch and gull-wing leads. Package dimensions: 8.75 × 5.8 mm body, 1.75 mm height, 0.46 mm max lead width.

2, 6, 10, 14	Non-inverting Input (A/B/C/D)	Reference input for each op-amp; matched to inverting inputs for CMR optimization.
3, 7, 11, 12	Output (A/B/C/D)	Class-AB output stage delivering ±14.6 V swing into 10 kΩ and ±13.2 V into 600 Ω.

8	Negative Supply (V_CC−)	Connects to −V_CC; supports down to −15 V; decoupling required within 1 cm for noise immunity.

Key Features

Feature	Design Value

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
LM324DT	Higher V_io (3 mV max), lower GBP (1.2 MHz), no macromodel, 700 µA per amp supply current.	Acceptable for cost-sensitive industrial controls but unsuitable for audio or precision sensor front-ends.	Select only when budget constraints outweigh noise, speed, and THD requirements.
NE5532D	Lower noise (5 nV/√Hz), higher slew rate (9 V/µs), but dual-only (not quad); requires two packages for same channel count.	Better for discrete audio stages; not pin-compatible; increases PCB area and BOM count.	Choose when ultimate audio fidelity is needed and board space allows dual-device layout.

Compared with LM324DT and NE5532D, TS524IDT uniquely balances low noise, quad integration, and SPICE-model support - making it optimal for space-constrained, high-channel-count precision analog systems where simulation fidelity and thermal stability are critical.

FAQ

What is the maximum recommended supply voltage for TS524IDT?

The absolute maximum supply voltage is ±18 V, but the device is characterized and guaranteed for stable operation from ±2.5 V to ±15 V. Operating beyond ±15 V risks exceeding junction temperature limits and invalidating parametric guarantees, especially under load or elevated ambient temperatures.

Does TS524IDT support single-supply operation?

No - TS524IDT is specified exclusively for dual-supply operation (±V_CC). Its input common-mode range extends to ±13 V and output swing to ±14.6 V, but it lacks rail-to-rail input or true single-supply biasing architecture. For single-supply designs, consider ST's TS912 or TLV2464 alternatives.

Is the TS524IDT pinout compatible with other SO14 quad op-amps like LM324 or TL074?

No - TS524IDT uses a non-standard pinout: pins 1/5/9/13 are inverting inputs, pins 2/6/10/14 are non-inverting inputs, and pins 3/7/11/12 are outputs. This differs from LM324 (outputs on pins 1/7/8/14) and TL074 (outputs on pins 1/7/8/14), requiring PCB redesign for substitution.

How does the 2 µV/°C input offset drift impact long-term calibration in sensor systems?

Over a 100°C temperature span (−40°C to +60°C), the drift contributes ≤200 µV of additional offset error - equivalent to ~0.02% of full-scale for a ±10 V output range. This is acceptable for 12-bit systems but may require periodic auto-zeroing or software correction in 16-bit+ precision applications.
