Product details
Overview
TS9224IYDT from STMicroelectronics is an automotive-qualified quad rail-to-rail input/output operational amplifier optimized for precision signal conditioning in harsh environments. It delivers 4 MHz gain bandwidth, 1.3 V/μs slew rate, 500 µV max input offset voltage, and drives capacitive loads up to 500 pF - enabling stable operation in sensor front-ends and actuator interfaces within automotive ECUs.
For engineers reviewing the TS9224IYDT datasheet, TS9224IYDT pinout, TS9224IYDT application, or TS9224IYDT equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40°C to +125°C), 80 mA output drive capability, low 9 nV/√Hz input noise, and SO14 package compatibility with legacy PCB layouts requiring quad op-amp functionality.
Technical Context
The TS9224IYDT integrates four independent high-precision amplifiers on a single die, each featuring rail-to-rail input common-mode range (VCC− −0.2 V to VCC+ +0.2 V) and rail-to-rail output swing. Its internal architecture ensures stability with capacitive loads up to 500 pF without external compensation.
It operates across a wide supply range (2.7 V to 12 V), supports high CMRR (min 60 dB) and PSRR (min 70 dB), and maintains low THD (0.005% at 1 kHz) under 600 Ω load - making it suitable for analog signal chains where fidelity and DC accuracy are critical in automotive powertrain and body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 12 V - enables direct integration into 3.3 V, 5 V, and 12 V automotive subsystems without level-shifting. |
| Input Offset Voltage (max) | 500 µV - ensures ≤0.5 mV error in 1 V full-scale sensor measurements, critical for precision current sensing. |
| Gain Bandwidth Product | 4 MHz - supports closed-loop bandwidth >1 MHz with moderate gain, sufficient for active filtering and fast feedback loops. |
| Slew Rate | 1.3 V/μs - allows clean 10 Vpp output at ≥100 kHz without slew-induced distortion in audio and servo drivers. |
| Output Current (per channel) | 80 mA - directly drives 600 Ω loads (e.g., line outputs) or low-impedance actuators without external buffers. |
| Input Noise Density | 9 nV/√Hz at 1 kHz - minimizes added noise in low-level sensor amplification stages (e.g., thermocouple, strain gauge). |
| Channel Separation | 120 dB - prevents crosstalk between adjacent channels in multi-signal acquisition systems like ADAS sensor fusion units. |
Pinout & Package
TS9224IYDT is housed in a 14-pin SOIC (SO14) package, 8.75 mm × 4.0 mm footprint, 1.75 mm height, with 1.27 mm pitch - compatible with standard automated assembly and IPC-7351B SOIC-14 land patterns.

| 5 | In2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; enables independent dual-path signal processing. |
| 6 | In2− | Inverting input of Channel 2 - used with external resistors for programmable gain or differential amplification. |
| 7 | Out2 | Output of Channel 2 - rail-to-rail swing allows full dynamic range utilization in battery-powered systems. |
| 8 | VCC+ | Positive supply rail - accepts 2.7–12 V; internal ESD protection rated to 3 kV HBM per pin. |
| 9 | In3− | Inverting input of Channel 3 - shares same process-matched characteristics as Channels 1 and 2 for consistent performance. |
| 10 | In3+ | Non-inverting input of Channel 3 - supports biasing via resistor dividers for single-supply sensor interface applications. |
| 11 | Out3 | Output of Channel 3 - maintains phase margin >60° with 500 pF load, eliminating need for isolation resistors. |
| 12 | In4+ | Non-inverting input of Channel 4 - designed for low input bias current (15–90 nA) to minimize leakage errors in high-Z sources. |
| 13 | In4− | Inverting input of Channel 4 - matched to In3−/In2−/In1− for common-mode rejection in multi-channel differential receivers. |
| 14 | Out4 | Output of Channel 4 - delivers identical AC/DC specs as other channels, enabling synchronized multi-output control loops. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of supply rails in single-supply systems (e.g., 3.3 V microcontroller ADC reference), maximizing SNR without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324QDRQ1 | Lower GBW (1 MHz), higher Vio (3 mV max), no 500 pF load drive guarantee. | Targeted at cost-sensitive body electronics; not recommended for high-fidelity audio or fast servo loops. | Select only if supply voltage is limited to 5.5 V and load capacitance remains <100 pF. |
| OPA4197IPWR | Higher precision (10 µV Vio), lower noise (5.5 nV/√Hz), but requires ≥4.5 V supply and lacks AEC-Q100 Grade 1 rating. | Preferred for industrial test equipment; unsuitable for under-hood automotive deployment without additional qualification. | Choose only for non-automotive precision instrumentation where extended temperature range is not required. |
Compared with LMV324QDRQ1 and OPA4197IPWR, TS9224IYDT uniquely balances automotive qualification, 500 pF load stability, and 4 MHz bandwidth - making it the only option among the three that meets both ASIL-B signal chain timing and noise requirements in engine control modules.

FAQ
Is TS9224IYDT pin-compatible with standard SO14 quad op-amps like LM324?
No, TS9224IYDT uses a non-standard pinout optimized for rail-to-rail operation and noise isolation: Pin 4 is VCC− (not GND), Pin 8 is VCC+, and inputs/outputs follow ST's proprietary channel mapping. Direct replacement requires PCB redesign or adapter board.
What is the maximum allowable capacitive load for stable operation?
The TS9224IYDT is characterized for stable operation with up to 500 pF capacitive load on any output, verified across temperature and supply voltage ranges. Exceeding this value may cause peaking or oscillation unless compensated with a series isolation resistor.
Does TS9224IYDT support single-supply operation below 3 V?
Yes - it operates down to 2.7 V supply, with rail-to-rail input extending to VCC− −0.2 V and output swinging within 50 mV of either rail at 10 kΩ load. At 2.7 V, output swing is typically 0.05 V to 2.65 V, enabling use with 3.3 V microcontrollers.
How does the AEC-Q100 Grade 1 qualification impact reliability testing?
AEC-Q100 Grade 1 certification requires TS9224IYDT to pass accelerated stress tests including 1000-hour HTOL at 125°C junction temperature, temperature cycling (−40°C to +125°C, 1000 cycles), and ESD testing (3 kV HBM), ensuring >15-year field reliability in automotive under-hood applications.
