Product details
Overview
TSV524AIYPT 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 typ input bias current, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C) - enabling use in battery-powered sensor front-ends and automotive cabin control modules.
For engineers reviewing the TSV524AIYPT datasheet, TSV524AIYPT pinout, TSV524AIYPT application, or TSV524AIYPT equivalent, key selection criteria include its ultra-low quiescent current, rail-to-rail operation across 2.7–5.5 V supply, guaranteed performance over extended temperature, and QFN16 3×3 mm package with exposed pad for thermal management in space-constrained PCBs.
Technical Context
The TSV524AIYPT employs a complementary PMOS/NMOS input stage enabling true rail-to-rail input common-mode range (VCC− −0.1 V to VCC+ +0.1 V) without phase reversal. Its unity-gain-stable architecture supports stable operation with up to 100 pF capacitive load, and internal compensation ensures consistent 55° phase margin across supply voltages (2.7–5.5 V) and temperatures (−40 °C to +125 °C).
Designed for precision analog signal chains, it achieves a high merit factor (1.15 MHz GBP / 45 μA) while maintaining low THD+N (0.002% at 1 kHz, 1 VPP) and low 1/f noise (14 µVPP, 0.1–10 Hz). The device's CMR (76 dB typ at 5 V) and SVR (87 dB typ) ensure robust rejection of supply and common-mode disturbances in noisy automotive environments.
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 loss |
| Supply Current per Channel | 45 μA (typ at 5 V): extends battery life in always-on sensor nodes beyond 10 years at 10 μA system budget |
| Input Offset Voltage | 800 μV (max at 25 °C): limits initial error to <0.02% FS in 4 V full-scale medical sensor interfaces |
| Input Bias Current | 1 pA (typ): preserves signal integrity when interfacing >1 GΩ impedance sources (e.g., pH electrodes) |
| Rail-to-Rail I/O | Input: VCC− −0.1 V to VCC+ +0.1 V; Output: within 35 mV of rails (10 kΩ load): maximizes dynamic range in single-supply 3.3 V systems |
| Operating Temperature | −40 °C to +125 °C: meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics |
| ESD Robustness | HBM: 4 kV; CDM: 1.3 kV (QFN16): withstands handling and assembly without protection diodes |
Pinout & Package
TSV524AIYPT is housed in a thermally enhanced QFN16 (3 mm × 3 mm, 0.5 mm pitch) package with an exposed thermal pad. The pad may be connected to VCC− or left floating per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13, 14, 15 | Inverting Input (IN1−, IN2−, IN3−, IN4−) | Differential inputs for each op-amp channel; accept signals down to VCC− −0.1 V |
| 2, 3, 5, 6 | Non-inverting Input (IN1+, IN2+, IN3+, IN4+) | High-impedance inputs (1 pA bias) for sensor/feedback connections |
| 4, 7, 10, 12 | Output (OUT1, OUT2, OUT3, OUT4) | Rail-to-rail outputs capable of sourcing/sinking ±36 mA (5.5 V, 25 °C) |
| 8, 16 | VCC+ | Positive supply pin; decoupling capacitor required within 2 mm |
| 9, 11 | VCC− | Negative supply (GND for single-supply); connects to exposed thermal pad if used |
| 14 | NC | No connect - must be left unconnected or tied to VCC− (not VCC+) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified (Grade 1) | Validated for automotive applications requiring −40 °C to +125 °C operation and robust reliability |
| Unity-gain stable with 100 pF load | Eliminates need for external compensation in active filter and driver circuits |
| Low 1/f noise (14 µVPP, 0.1–10 Hz) | Reduces baseline drift in DC-coupled medical instrumentation and precision weigh scales |
| High PSRR (87 dB typ at 5 V) | Maintains accuracy in systems sharing noisy digital power rails (e.g., infotainment ECUs) |
| Low THD+N (0.002% at 1 kHz) | Preserves signal fidelity in audio pre-amplifiers and ultrasonic transducer receivers |
Applications

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 | Non-AEC-Q100 version; same electrical specs but rated for −40 °C to +85 °C only | Suitable for industrial or consumer portable devices, not automotive | Select when cost sensitivity outweighs automotive qualification requirement |
| LMV824DT | Higher GBP (5.5 MHz), higher ICC (220 μA/ch), no AEC-Q100, SO-14 package | Better for bandwidth-critical audio or fast control loops where power is less constrained | Choose when >1 MHz signal bandwidth is needed and thermal/power budgets allow |
Compared with TSV524AIYPT, TSV524IYPT sacrifices automotive qualification for lower unit cost in commercial environments, while LMV824DT trades 5× higher supply current for 4.8× greater bandwidth - making TSV524AIYPT optimal for ultra-low-power, high-reliability automotive signal chains where 1.15 MHz suffices.

FAQ
Can TSV524AIYPT drive a 1000 pF capacitive load directly?
No. The datasheet specifies unity-gain stability only up to 100 pF. Driving 1000 pF requires an isolation resistor (≥100 Ω, per Figure 29) between the output and load to maintain phase margin >45°. Without this resistor, oscillation or excessive overshoot occurs due to pole splitting in the feedback loop.
What is the maximum allowable input voltage beyond the rails?
The absolute maximum rating allows input voltages from (VCC− − 0.2 V) to (VCC+ + 0.2 V), but the functional common-mode range is specified as VCC− − 0.1 V to VCC+ + 0.1 V. Exceeding ±0.1 V may degrade CMR, increase Vio, or cause temporary phase reversal - avoid sustained operation beyond these limits.
How does the exposed thermal pad affect thermal resistance?
When soldered to a 200 mm² copper pour (2 oz, inner layer), the QFN16's exposed pad reduces RthJA from 45 °C/W (no pad connection) to ≤25 °C/W. This lowers junction temperature by up to 30 °C at full 144 μA total supply current, critical for reliability at 125 °C ambient.
Is TSV524AIYPT compatible with standard TSSOP14 footprints?
No. TSV524AIYPT uses a QFN16 (3×3 mm) package, while TSSOP14 is a 5×4.4 mm body with 0.65 mm pitch. Pin count, pitch, and pad layout differ fundamentally. Migration requires PCB redesign; however, the pin functions (IN+, IN−, OUT, VCC±) are electrically identical to the TSSOP14 variant TSV524AYPT.
