Product details
Overview
TSV524AIPT from STMicroelectronics is a quad-channel, rail-to-rail input/output operational amplifier optimized for low-power, high-precision signal conditioning in automotive and portable systems. It delivers 1.15 MHz gain bandwidth at only 45 μA per channel (5 V), features 800 μV max offset voltage, 1 pA typical input bias current, and operates from 2.7 to 5.5 V - enabling direct interface with high-impedance sensors in battery-powered automotive ECUs.
For engineers reviewing the TSV524AIPT datasheet, TSV524AIPT pinout, TSV524AIPT application, or TSV524AIPT equivalent, this device is selected for ultra-low quiescent current, AEC-Q100 qualification, rail-to-rail operation across extended temperature (–40 °C to +125 °C), and stable unity-gain performance with 100 pF capacitive loads - critical for sensor front-ends and active filtering in space-constrained designs.
Technical Context
The TSV524AIPT employs complementary PMOS/NMOS input stages enabling true rail-to-rail input common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V) without phase reversal, while maintaining CMRR ≥ 76 dB and PSRR ≥ 87 dB at 5 V. Its architecture supports simultaneous N- and P-pair conduction in mid-rail regions to enhance speed and merit factor.
It achieves unity-gain stability with 100 pF capacitive loads and delivers 0.89 V/μs slew rate at 5 V, with output swing within 35 mV of both rails into 10 kΩ. The device uses a single-supply topology with independent VCC+/VCC− pins (not ground-referenced), supporting flexible biasing in dual-rail or single-rail configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 1.15 MHz typ. at 5 V - enables stable amplification up to ~1 MHz in unity-gain buffer or low-gain configurations without compensation. |
| Supply Current per Channel | 45 μA typ. at 5 V - extends battery life in always-on sensor nodes; 60 μA max over full temp range ensures predictable power budgeting. |
| Input Offset Voltage | 600 μV max at 25 °C (TSV524A grade) - reduces DC error in precision instrumentation and medical front-ends without trimming. |
| Input Bias Current | 1 pA typ. - preserves signal integrity when interfacing with >1 GΩ source impedances (e.g., piezoelectric or pH sensors). |
| Rail-to-Rail I/O | Input: VCC− − 0.1 V to VCC+ + 0.1 V; Output: within 35 mV of rails - maximizes dynamic range in low-voltage (2.7 V) systems. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive applications and industrial edge sensors without derating. |
| AEC-Q100 Grade | Qualified to Grade 1 (–40 °C to +125 °C) - meets automotive reliability requirements for ECU, ADAS, and body control modules. |
Pinout & Package
TSV524AIPT is housed in a 14-lead TSSOP package (3.0 mm × 4.4 mm, 0.65 mm pitch) with exposed thermal pad connected to VCC−. Pin numbering follows standard IC orientation (pin 1 marked by dot or bevel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (IN1−, IN2−, IN3−, IN4−) | Differential inputs for each op-amp channel; high-impedance (1 pA bias) node for precision feedback networks. |
| 2, 6, 10, 14 | Non-inverting Input (IN1+, IN2+, IN3+, IN4+) | Reference inputs accepting signals from 0.1 V below VCC− to 0.1 V above VCC+ - supports true rail-to-rail sensor interfacing. |
| 3, 7, 11, 12 | Output (OUT1, OUT2, OUT3, OUT4) | Capable of sourcing/sinking ≥36 mA (5 V, 25 °C); swings to within 35 mV of supply rails into 10 kΩ load. |
| 4 | VCC+ | Positive supply rail (2.7–5.5 V); decoupling capacitor required near pin for stability with capacitive loads. |
| 8 | VCC− | Negative supply rail (typically ground in single-supply use); connects to exposed thermal pad for improved thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage with no phase reversal | Validated over full common-mode range (VCC− − 0.1 V to VCC+ + 0.1 V); eliminates output inversion risk during power-up or overvoltage transients. |
| Ultra-low input bias current (1 pA typ.) | Enables direct connection to high-Z sources (e.g., thermopiles, photodiodes) without signal attenuation or drift-induced errors. |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in sensor buffering and active filter stages - simplifies layout and reduces BOM count. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use including HTOL, TC, ESD (4 kV HBM), and latch-up immunity (200 mA) - reduces qualification effort for Tier 1 suppliers. |
| Low-frequency noise (14 µVPP, 0.1–10 Hz) | Minimizes baseline drift in DC-coupled medical instrumentation (e.g., ECG front-ends) and precision weigh scales. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-power rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV524IPT | Standard grade (non-A): 1.5 mV max VIO at 25 °C vs. 600 μV for TSV524A; same package, pinout, and quiescent current. | Acceptable for non-precision automotive cabin controls (e.g., mirror position feedback) where offset drift <3.1 mV over –40 °C to +125 °C is tolerable. | Select TSV524IPT for cost-sensitive volume production where full A-grade offset spec is unnecessary. |
| LMV824DT | Higher GBP (5.5 MHz), higher ICC (120 μA/ch), no AEC-Q100 qualification; SO-14 package compatible but not pin-for-pin. | Suitable for industrial test equipment requiring faster settling, but unsuitable for automotive or long-life battery applications due to power and qualification gaps. | Choose LMV824DT only when bandwidth >2 MHz is mandatory and automotive qualification is not required. |
Compared with TSV524IPT, the TSV524AIPT provides tighter offset and drift specs essential for precision sensor interfaces, while LMV824DT trades power efficiency and qualification for raw speed - making TSV524AIPT the optimal choice for AEC-Q100-compliant, ultra-low-power, high-accuracy quad amplification.

FAQ
What is the maximum capacitive load the TSV524AIPT can drive without external compensation?
The TSV524AIPT is unity-gain stable with up to 100 pF capacitive load at the output, as verified in the datasheet (DS8862, Section 5.5). For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω, value dependent on capacitance per Figure 29) must be added between the output and load to maintain phase margin ≥55° and prevent oscillation.
Can the TSV524AIPT operate from a single 2.7 V supply with rail-to-rail input and output?
Yes - the TSV524AIPT fully supports single-supply operation from 2.7 V to 5.5 V. Its rail-to-rail input accepts signals from VCC− − 0.1 V to VCC+ + 0.1 V, and its output swings within 35 mV of both rails into 10 kΩ, delivering usable dynamic range even at minimum supply voltage.
How does the TSV524AIPT differ from the TSV524A in QFN16 package?
The TSV524AIPT (TSSOP14) and TSV524AQTR (QFN16 3×3 mm) share identical electrical specifications, AEC-Q100 qualification, and pin-compatible functionality. The key difference is package: TSSOP14 offers easier manual assembly and rework, while QFN16 provides superior thermal performance (RthJA = 45 °C/W vs. 100 °C/W) and smaller footprint for space-constrained PCBs.
Is the exposed thermal pad on the TSSOP14 package electrically connected?
Yes - the exposed pad on the TSV524AIPT TSSOP14 package is internally connected to VCC− (pin 8) and must be soldered to a PCB copper pour tied to the VCC− net. This improves thermal dissipation and reduces junction temperature by up to 25 °C under continuous 45 μA/channel operation at +125 °C ambient.
