Product details
Overview
TSV524IPT from STMicroelectronics is a quad, rail-to-rail input/output operational amplifier optimized for ultra-low-power, high-precision signal conditioning in automotive and portable systems. It delivers 1.15 MHz gain bandwidth at 45 μA per channel (5 V), 800 μV max offset voltage, 1 pA typical input bias current, and operates from 2.7–5.5 V - enabling direct interfacing with high-impedance sensors in battery-powered ECUs.
For engineers reviewing the TSV524IPT datasheet, TSV524IPT pinout, TSV524IPT application, or TSV524IPT equivalent, key selection criteria include its AEC-Q100 qualification, unity-gain stability with 100 pF load, -40°C to +125°C operating range, and QFN16 3×3 mm package with exposed pad - critical for thermal management in compact automotive modules.
Technical Context
The TSV524IPT employs a complementary PMOS/NMOS input stage enabling true rail-to-rail input operation across VCC− −0.1 V to VCC+ +0.1 V, with dual-pair overlap boosting slew rate and maintaining phase integrity during common-mode transitions. Its architecture ensures no phase reversal under overdrive conditions, verified per Figure 28 of DS8862 Rev 4.
It achieves unity-gain stability driving up to 100 pF capacitive loads without external compensation, supported by 55° phase margin and 7 dB gain margin at 5.5 V. The device's low 0.89 V/μs slew rate (5 V) and 57 nV/√Hz input noise (1 kHz) are tightly coupled to its 1.15 MHz GBP, delivering optimal speed/power trade-off for sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.15 MHz typ. at 5 V - enables stable closed-loop gain ≥10 up to ~115 kHz with minimal phase lag |
| Supply Current per Channel | 45 μA typ. at 5 V - extends battery life in always-on automotive sensors (e.g., tire pressure monitors) |
| Input Offset Voltage | 800 μV max. at 25°C - reduces DC error in precision bridge amplifiers without trimming |
| Input Bias Current | 1 pA typ. - preserves signal integrity when conditioning outputs from piezoresistive or MEMS sensors |
| Rail-to-Rail I/O | VIN: VCC−−0.1 V to VCC++0.1 V; VOUT: within 35 mV of rails - maximizes dynamic range in 3.3 V ADC interfaces |
| Operating Temperature | −40°C to +125°C - meets under-hood automotive ambient requirements per AEC-Q100 Grade 1 |
| ESD Robustness | 4 kV HBM - withstands handling and board-level transients in production and field environments |
Pinout & Package
TSV524IPT is housed in a thermally enhanced 16-pin QFN (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad. The pad may be connected to VCC− or left floating per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | Inverting Input (IN1− to IN4−) | Differential inputs for each op-amp channel; accept signals down to VCC− −0.1 V |
| 2, 4, 6, 8 | Non-inverting Input (IN1+ to IN4+) | High-impedance inputs (1 pA bias) for sensor bridges or reference taps |
| 9, 10, 11, 12 | Output (OUT1 to OUT4) | Rail-to-rail outputs sinking/sourcing ≥36 mA (5 V) into 10 kΩ load |
| 13 | VCC+ | Positive supply rail (2.7–5.5 V); decoupling capacitor required adjacent to pin |
| 14 | VCC− | Negative supply rail (typically GND); connects to exposed thermal pad for thermal relief |
| 15, 16 | No Connect (NC) | Unused pins; must remain unconnected or tied to VCC− per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified (Grade 1) | Validated for automotive use up to +125°C ambient, including temperature cycling and HTOL stress |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in active filter or buffer designs driving long PCB traces |
| Rail-to-rail input common-mode range | Extends usable input swing beyond supply rails by 100 mV - critical for single-supply sensor biasing |
| Low 1 pA input bias current | Minimizes voltage drop across high-value feedback networks (e.g., >10 MΩ) in pH or gas sensors |
| 4 kV HBM ESD rating | Reduces risk of field failure during assembly or end-user handling in non-ESD-controlled environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV524IYPT | Same silicon, QFN16 3×3 mm but with enhanced AEC-Q100 Grade 0 qualification (−40°C to +150°C junction) | Required for engine bay or transmission control units exceeding +125°C ambient | Select when extended junction temperature rating is mandated by system thermal profile |
| LMV824IDR | Higher GBP (5.5 MHz), higher supply current (160 μA/ch), no AEC-Q100 qualification | Suitable for non-automotive industrial test equipment needing faster settling | Choose only for cost-sensitive non-automotive designs where qualification and ultra-low power are not required |
Compared with TSV524IPT, TSV524IYPT offers extended temperature capability at identical electrical performance and footprint, while LMV824IDR trades AEC-Q100 compliance and power efficiency for higher bandwidth - making TSV524IPT the optimal balance for automotive sensor nodes requiring longevity, low quiescent current, and qualification assurance.

FAQ
What is the maximum capacitive load the TSV524IPT can drive without external compensation?
The TSV524IPT is unity-gain stable with up to 100 pF capacitive load, as confirmed in Table 3 (AC performance) and Figure 29 of DS8862 Rev 4. Driving larger loads requires an in-series resistor (e.g., 10–100 Ω) between output and load, with stability validated via bench testing and SPICE simulation using ST's official PSpice model.
Can the exposed thermal pad on the QFN16 package be left floating?
Yes - the exposed pad on the TSV524IPT QFN16 package may be left electrically floating or connected to VCC− (GND), per Section 1 of DS8862 Rev 4. Thermal performance improves when soldered to a copper pour tied to VCC−, but floating is acceptable if thermal dissipation requirements are modest (<100 mW total).
How does the TSV524IPT handle input overvoltage beyond the supply rails?
The TSV524IPT supports input voltages from VCC− −0.2 V to VCC+ +0.2 V (Table 1, Absolute Maximum Ratings). Exceeding this risks latch-up or damage; absolute max differential input is ±VCC. For overvoltage protection, ST recommends adding series resistors (per Section 5.3) to limit input current to <10 mA.
Is the TSV524IPT pin-compatible with other quad op-amps in TSSOP14 packages?
No - the TSV524IPT uses a 16-pin QFN layout incompatible with standard 14-pin TSSOP op-amps. However, ST's TSV524 variant in TSSOP14 (TSV524T) shares identical electrical specs and functional pin mapping for IN+/IN−/OUT/VCC pins, though pin count and spacing differ; migration requires PCB redesign.
