Product details
Overview
TS9224ID from STMicroelectronics is a quad rail-to-rail input/output operational amplifier optimized for high-precision signal conditioning in automotive and industrial systems. 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 while operating from 2.7 V to 12 V supply rails.
For engineers reviewing the TS9224ID datasheet, TS9224ID pinout, TS9224ID application, or TS9224ID equivalent, this device is selected for low-distortion audio buffering, servo control loops, line driver stages, and precision sensor signal amplification where rail-to-rail swing and stability with heavy capacitive loads are required.
Technical Context
The TS9224ID employs a fully complementary input stage enabling true rail-to-rail common-mode input range (VCC− −0.2 V to VCC+ +0.2 V) and rail-to-rail output swing within 50 mV of each rail under 10 kΩ load. Its internal compensation ensures unity-gain stability even with 500 pF capacitive loads at the output.
It features 80 mA short-circuit output current per channel, 9 nV/√Hz input voltage noise at 1 kHz, and 0.005% THD+N at 1 kHz with 2 Vpp output into 600 Ω - confirming suitability for high-fidelity analog front-ends and closed-loop actuator drivers.
Key Specifications

|---|---|
| Input Offset Voltage | ≤500 µV max - enables DC-coupled precision gain stages without significant output error. |
| Gain Bandwidth Product | 4 MHz - supports stable closed-loop operation up to ~300 kHz at gain = 13 (e.g., active filters). |
| Slew Rate | 1.3 V/µs - allows clean 10 Vpp output at ≥100 kHz without slew-induced distortion. |
| Supply Voltage Range | 2.7 V to 12 V - compatible with single-supply 3.3 V, 5 V, and dual ±6 V systems. |
| Capacitive Load Drive | Up to 500 pF - eliminates need for isolation resistors when driving ADC inputs or long cables. |
| Output Short-Circuit Current | 80 mA - sustains drive into low-Z loads like 600 Ω headphones or 32 Ω actuators. |

Use Scenario: Driving stereo 32 Ω headphones from a DAC output in automotive infotainment head units. IC Role / Device Role / Timing Role: Quad op-amp configured as two independent stereo buffers (L/R per channel pair), providing low-noise, low-THD voltage gain. Use Value: 9 nV/√Hz noise and 0.005% THD+N preserve audio fidelity; 80 mA output current ensures full 10 Vpp swing into 32 Ω without clipping. |
Use Scenario: Transmitting analog sensor signals (e.g., pressure, temperature) over 1–2 m PCB traces to an ADC. IC Role / Device Role / Timing Role: Unity-gain buffer isolating high-impedance sensor outputs from trace capacitance and ADC input loading. Use Value: Rail-to-rail output and 500 pF capacitive load drive eliminate signal droop or phase shift; 500 µV max Vio avoids DC calibration overhead. |
| Servo Amplifier | Signal Conditioning |

IC Role / Device Role / Timing Role: Precision instrumentation amplifier front-end (with external resistors) or differential receiver stage. Use Value: 2 µV/°C drift and 65 dB min CMRR maintain accuracy across wide temperature ranges; SO14 package allows dense layout with minimal thermal gradients. |
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 |
|---|---|---|---|
| LMV324DR | Lower GBW (1 MHz), higher Vio (3 mV max), no AEC-Q100 qualification. | Not suitable for automotive-grade signal chains requiring <1 mV DC error or >100 kHz bandwidth. | Select only for cost-sensitive consumer-grade designs with relaxed precision and temperature requirements. |
| TLV2464CDR | Higher quiescent current (650 µA/channel vs. 1.2 mA total), lower output current (35 mA), no 500 pF load rating. | Limited drive capability restricts use in headphone or actuator interfaces; less stable with capacitive loads. | Prefer for ultra-low-power battery-operated systems where output drive and capacitive stability are secondary. |
Compared with LMV324DR and TLV2464CDR, TS9224ID uniquely combines automotive qualification, 500 µV Vio, 80 mA output, and guaranteed 500 pF capacitive load stability - making it the only option among the three for demanding automotive sensor and audio buffer applications.

FAQ
What is the maximum capacitive load the TS9224ID can drive while remaining stable?
The TS9224ID is characterized and guaranteed stable with capacitive loads up to 500 pF at the output, as confirmed in Figure 4 of the official datasheet (DocID15718 Rev 5). This eliminates the need for series isolation resistors when interfacing with ADCs, long PCB traces, or coaxial cables - unlike many general-purpose op-amps that require external compensation above 100 pF.
Does the TS9224ID support single-supply operation down to 2.7 V?
Yes - the TS9224ID operates from 2.7 V to 12 V total supply range, with rail-to-rail input and output swing verified across this entire range. At 2.7 V, it maintains 500 µV max input offset voltage, 4 MHz gain-bandwidth, and 1.3 V/µs slew rate, enabling precision analog functions in battery-powered automotive modules and portable industrial tools.
Is the TS9224ID qualified for automotive applications?
Yes - the TS9224ID is AEC-Q100 qualified (Grade 1, −40 °C to +125 °C ambient), with enhanced ESD protection (3 kV HBM), latch-up immunity, and tested reliability under automotive stress conditions. It appears in Table 9 of the datasheet with "IY" suffix variants explicitly designated for automotive use.
How does the TS9224ID's 80 mA output current benefit system design?
The 80 mA per-channel short-circuit output current allows direct drive of low-impedance loads such as 32 Ω actuators, 600 Ω headphones, or 100 Ω transmission lines - eliminating external buffer transistors or dedicated driver ICs. This reduces BOM count, PCB area, and thermal complexity while maintaining signal integrity and DC accuracy.
