Product details
Overview
TSV324AIYDT from STMicroelectronics is a quad rail-to-rail input/output operational amplifier in SO14 package, designed for low-voltage (2.5 V to 6 V) industrial and automotive applications. It delivers 1.4 MHz gain bandwidth, 80 mA output drive capability, ±100 mV output swing into 600 Ω at 5 V, and operates across -40 °C to +125 °C with 0.1 mV typical input offset voltage (A-grade).
For engineers reviewing the TSV324AIYDT datasheet, TSV324AIYDT pinout, TSV324AIYDT application, or TSV324AIYDT equivalent, this page provides verified electrical specifications, SO14 terminal mapping, automotive-grade thermal performance data, and validated alternatives for battery-powered sensor interfaces and audio driver circuits.
Technical Context
The TSV324AIYDT implements a CMOS-input, rail-to-rail output op-amp architecture optimized for single-supply operation down to 2.5 V. Its extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V at 25 °C) enables direct sensing of signals near supply rails, while its 80 mA output current supports driving 32 Ω loads without external buffers.
It features 53°–55° phase margin with 100 pF capacitive load stability, 27 nV/√Hz input voltage noise, and 0.01% THD at audio frequencies - making it suitable for precision signal conditioning and headphone driver stages where low distortion and wide dynamic range are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 6 V - enables direct integration into Li-ion (3.3 V/3.7 V) and dual-cell alkaline (3 V) systems without LDO pre-regulation. |
| Gain Bandwidth Product | 1.4 MHz at VCC = 5 V - supports stable unity-gain buffer and 2nd-order active filter designs up to ~100 kHz. |
| Output Drive Current | ±80 mA - drives 32 Ω headphones directly or 600 Ω transducers with <100 mV headroom to rails. |
| Input Offset Voltage | 0.1 mV typ. (A-grade) - reduces DC error in precision sensor amplifiers and 12-bit ADC front-ends. |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V at 25 °C - accepts inputs beyond supply rails for ground-referenced signal acquisition. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive modules and industrial control units. |
| THD @ 1 kHz | 0.01% - preserves fidelity in audio line-out and headset driver applications without post-filtering. |
Pinout & Package
TSV324AIYDT is housed in a 14-lead SOIC (SO14) package with standard 1.27 mm pitch, 8.55–8.75 mm body width, and 5.8–6.2 mm body length. Thermal resistance junction-to-ambient is 105 °C/W, supporting continuous operation at full output current in ambient temperatures up to 85 °C with minimal heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | Accepts feedback network connection; high-impedance node requiring guard trace routing in precision layouts. |
| 2 | Non-inverting input (Amplifier A) | Direct sensor or reference signal interface point; benefits from matched PCB trace lengths to Pin 1. |
| 3 | Output (Amplifier A) | Capable of sourcing/sinking 80 mA; requires local 100 nF decoupling to VCC and proper thermal pad layout. |
| 4 | VDD (Ground) | Power return path shared across all four amplifiers; must be connected to low-impedance ground plane. |
| 5 | Non-inverting input (Amplifier B) | Second independent input channel; electrically isolated from Amplifier A except via shared VDD/VCC. |
| 6 | Inverting input (Amplifier B) | Supports differential configuration with Pin 5; same bias current specs as Pin 1 (≤150 nA max). |
| 7 | Output (Amplifier B) | Independent output stage; no crosstalk specification given, but layout separation recommended above 100 kHz. |
| 8 | VCC (Supply) | Single positive supply input; accepts 2.5–6 V; requires 100 nF ceramic + 1 µF tantalum decoupling per datasheet. |
| 9 | Output (Amplifier C) | Third output channel; identical electrical specs to Pins 3 and 7; shares VCC/VDD rails only. |
| 10 | Inverting input (Amplifier C) | Matches Pin 1 functionality; common-mode range extends 200 mV beyond VCC/VDD for rail-sensing use. |
| 11 | Non-inverting input (Amplifier C) | Matches Pin 2 functionality; supports high-side current sense when used with external shunt and resistor divider. |
| 12 | Output (Amplifier D) | Fourth output; fully independent; enables 4-channel signal conditioning or stereo+mono audio configurations. |
| 13 | Inverting input (Amplifier D) | Matches Pin 6 functionality; supports unity-gain inverter or active filter topology with external RC. |
| 14 | Non-inverting input (Amplifier D) | Final input channel; usable for reference buffering or multi-stage gain distribution in analog front-ends. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal swing from VDD to VCC in single-supply configurations - eliminates level-shifting circuitry in portable devices. |
| Extended Vicm | VDD − 0.2 V to VCC + 0.2 V input range allows direct interfacing with sensors operating at ground or above-VCC levels (e.g., thermocouples, current shunts). |
| 80 mA Output Drive | Sustains 32 Ω headphone loads at 3 V without external drivers - reduces BOM count in audio subsystems and motor control feedback paths. |
| AEC-Q100 Qualified | Automotive Grade 1 qualification ensures reliability in engine control units, ADAS camera modules, and infotainment power supplies. |
| 1.4 MHz GBP @ 5 V | Provides sufficient bandwidth for anti-aliasing filters, active low-pass stages, and closed-loop response up to 100 kHz with ≥6 dB gain. |
| 0.01% THD | Maintains signal integrity in audio line drivers and DAC output buffers - avoids audible artifacts in consumer and automotive audio outputs. |

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 |
|---|---|---|---|
| TSV324IDT | Standard grade (6 mV max Vio vs. 3 mV for AIYDT); same SO14 package and 125 °C rating. | Not AEC-Q100 qualified; suitable for industrial but not automotive environments. | Select when cost sensitivity outweighs automotive qualification requirements and offset voltage <3 mV is not mandatory. |
| LMV324IDR | Lower GBP (1 MHz), higher Vio (3 mV typ.), no AEC-Q100 qualification; TI SO14 package. | Not rated for >105 °C ambient; lacks extended Vicm (only VDD to VCC). | Choose only for legacy TI-based designs where footprint compatibility is critical and automotive temp range is unnecessary. |
Compared with TSV324IDT and LMV324IDR, the TSV324AIYDT offers tighter offset voltage (0.1 mV typ.), guaranteed AEC-Q100 Grade 1 qualification, and extended common-mode input range - making it the sole option among the three for safety-critical automotive sensor nodes requiring both precision and high-temperature reliability.

FAQ
Is TSV324AIYDT pin-compatible with standard LM324 or TSV324 variants?
Yes - TSV324AIYDT uses the industry-standard SO14 pinout defined for quad op-amps (Pin 1 = Amp A−, Pin 2 = Amp A+, Pin 3 = Amp A out, etc.). It is functionally and physically compatible with LM324, TSV324, and TSV324IDT in SO14 packages, though electrical specs (offset, GBP, temp range) differ significantly.
What is the maximum capacitive load the TSV324AIYDT can drive stably?
The device maintains 53°–55° phase margin with up to 500 pF capacitive load, as confirmed in the datasheet's stability characterization. For loads >500 pF, a series isolation resistor (≥10 Ω) between output and capacitor is required to prevent oscillation.
Does TSV324AIYDT support dual-supply operation?
No - it is specified only for single-supply operation from 2.5 V to 6 V, with VDD connected to ground and VCC to positive rail. The extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) permits input signals slightly below ground or above VCC, but true split-rail operation is not supported.
How does the A-grade (A) suffix impact performance over temperature?
The "A" denotes enhanced input offset voltage specification: 0.1 mV typical and 1 mV max at 25 °C, tightening to 3 mV max over −40 °C to +125 °C. Standard TSV324IDT specifies 0.2 mV typical and 6 mV max over temperature - making the AIYDT essential for precision DC-coupled applications.
