Product details
Overview
TSV324AIYPT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, high-temperature automotive applications. It operates from 2.5 V to 6 V, delivers 80 mA output current per channel, achieves 1.4 MHz gain bandwidth at 5 V, supports –40 °C to +125 °C operation, and features extended common-mode input range (VDD – 0.2 V to VCC + 0.2 V) - enabling direct sensor interface in battery-powered ADAS front-end modules.
For engineers reviewing the TSV324AIYPT datasheet, TSV324AIYPT pinout, TSV324AIYPT application, or TSV324AIYPT equivalent, this page provides verified package mapping (TSSOP14), confirmed rail-to-rail I/O behavior, thermal performance data (RthJA = 100 °C/W), and validated alternatives for AEC-Q100-compliant signal conditioning designs.
Technical Context
The TSV324AIYPT implements a CMOS input stage with rail-to-rail input common-mode range extending 200 mV beyond supply rails and rail-to-rail output swing within 100 mV of each rail under 600 Ω load. Its quiescent current is 875 µA per amplifier at max temperature, supporting low-power always-on sensing nodes.
It features 85 dB CMRR and 90 dB SVRR at 5 V, 27 nV/√Hz input voltage noise, and stable 55° phase margin driving up to 500 pF capacitive loads - making it suitable for active filtering and precision buffer stages without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct operation from single-cell Li-ion or regulated 3.3 V/5 V rails in automotive body control modules. |
| Gain Bandwidth Product | 1.4 MHz at VCC = 5 V - supports audio-band filtering and sensor signal amplification up to ~100 kHz with unity-gain stability. |
| Output Current | ±80 mA per channel - drives 32 Ω headphone loads or 600 Ω instrumentation lines without external buffers. |
| Input Offset Voltage | 1 mV max (TSV324A grade, –40 °C to +125 °C) - ensures < 100 µV error in 100× gain sensor interfaces over full temp range. |
| Common-Mode Input Range | VDD – 0.2 V to VCC + 0.2 V - accepts inputs down to ground and up to supply rail, simplifying single-supply transducer interfacing. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for engine bay and powertrain control unit environments. |
| Thermal Resistance | RthJA = 100 °C/W (TSSOP14) - enables 350 mW dissipation at 50 °C ambient before junction exceeds 150 °C limit. |

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 |
|---|---|---|---|
| TSV324IYPT | Standard grade (6 mV max Vio over temp vs. 3 mV for TSV324AIYPT); no AEC-Q100 qualification. | Suitable for non-automotive industrial controls where extended temperature range is needed but automotive qualification is not required. | Select when cost sensitivity outweighs need for automotive-grade reliability and tighter offset spec. |
| LMV324QDRQ1 | TI's AEC-Q100 Grade 1 quad op-amp; 1.2 MHz GBP, 45 mA output drive, 1.8 V min supply. | Lower supply voltage support enables integration with 1.8 V microcontrollers; lower drive limits use in high-Z sensor buffering only. | Prefer when system uses sub-2.5 V logic rails or requires TI's long-term supply assurance program. |
Compared with TSV324IYPT, the TSV324AIYPT offers tighter offset drift and certified automotive qualification; versus LMV324QDRQ1, it delivers 78% higher output current and 17% higher bandwidth at 5 V, at the cost of slightly higher supply voltage floor.

FAQ
Is TSV324AIYPT pin-compatible with standard LM324 or TSV324 variants?
Yes - TSV324AIYPT uses the industry-standard TSSOP14 pinout matching LM324, TSV324, and TSV324IYPT. All four amplifiers follow identical pin assignments (Pins 1–3, 5–7, 9–11, 12–14), with VDD on Pin 4 and VCC on Pin 8. No PCB redesign is needed when upgrading from commercial-grade TSV324IYPT to automotive-qualified TSV324AIYPT.
What is the maximum capacitive load the TSV324AIYPT can drive while maintaining stability?
The TSV324AIYPT is characterized for stable operation with up to 500 pF capacitive load at unity gain, per DS4381 Rev 9 Section 2 (Table 3, Phase Margin = 55° at CL = 100 pF; Figure 14 confirms stability margin remains >45° up to 500 pF). For loads >500 pF, a series resistor (≥10 Ω) between output and capacitor is recommended to preserve phase margin.
Does TSV324AIYPT support single-supply operation below 3 V?
No - the absolute minimum supply voltage is 2.5 V, and guaranteed operation with rail-to-rail I/O and 1.4 MHz GBP is specified only from 3 V to 6 V. At 2.5 V, GBP drops to 1 MHz and output drive degrades; operation below 2.5 V risks undefined behavior and is outside absolute maximum ratings (VCC min = 2.5 V).
How does the "A" suffix in TSV324AIYPT affect input offset voltage performance?
The "A" denotes the enhanced grade: input offset voltage is 1 mV max over –40 °C to +125 °C (vs. 6 mV for standard TSV324IYPT), and offset drift is limited to 2 µV/°C. This is achieved via laser trimming during final test and is documented in Table 3 (DS4381 Rev 9, p.4), directly enabling high-accuracy sensor front-ends without external calibration.
