Product details
Overview
TS9224IDT 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. It is used in servo amplifiers and line drivers requiring low distortion and stable high-current output.
For engineers reviewing the TS9224IDT datasheet, TS9224IDT pinout, TS9224IDT application, or TS9224IDT equivalent, key selection criteria include rail-to-rail I/O swing, 80 mA output current capability, ±40 °C to +125 °C automotive-grade temperature range, and 9 nV/√Hz input noise performance at 1 kHz.
Technical Context
The TS9224IDT integrates four independent precision op-amps with unity-gain stable architecture supporting capacitive loads up to 500 pF without external compensation. Its input stage uses complementary bipolar transistors enabling rail-to-rail common-mode input range (VCC− −0.2 V to VCC+ +0.2 V) and low input bias current (15–90 nA).
Each amplifier provides 80 mA short-circuit output current, 65–85 dB CMRR, and 75–90 dB PSRR across 2.7–12 V supply. Phase margin remains ≥60° at unity gain with 100 pF load, ensuring robust stability in feedback configurations typical of active filters and sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz - supports closed-loop bandwidth up to ~3.5 MHz in unity-gain buffer configuration with 100 pF load. |
| Slew Rate | 1.3 V/µs - enables clean 10 Vpp output at ≥100 kHz without slew-induced distortion in audio and actuator drive applications. |
| Input Offset Voltage | 500 µV max - ensures ≤0.5 mV DC error in 10× gain instrumentation stages over full temperature range. |
| Output Current | 80 mA - drives 600 Ω loads to full rail-to-rail swing and sustains 500 pF capacitive loads without oscillation. |
| Supply Voltage Range | 2.7 V to 12 V - compatible with single-supply 3.3 V, 5 V, and dual-supply ±2.5 V or ±6 V systems. |
| Input Noise Density | 9 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal amplification (e.g., thermocouple, strain gauge). |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 for under-hood automotive modules and industrial control environments. |

| 11 | Out3 | Amplifier 3 output - maintains 120 dB channel separation to prevent crosstalk in multi-channel audio paths. |
| 12 | In4+ | Non-inverting input of amplifier 4 - enables simultaneous processing of four analog signals (e.g., motor phase sensing). |
| 13 | In4− | Inverting input of amplifier 4 - matched input impedance (15–90 nA bias) across all four inputs. |
| 14 | Out4 | Amplifier 4 output - capable of driving 500 pF directly, eliminating need for external isolation resistors in ADC driver designs. |

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 |
|---|---|---|---|
| LM324DT | Wider supply range (3–32 V), but higher Vio (3 mV max), lower GBW (1.2 MHz), no rail-to-rail I/O. | Acceptable for non-precision industrial comparators or slow-signal buffers where offset and speed are not critical. | Select only if cost sensitivity outweighs precision, noise, and speed requirements - not suitable for automotive AEC-Q100 designs. |
| TLV2464CDR | Rail-to-rail I/O, 6.4 MHz GBW, but lower output current (30 mA), narrower temp range (−40 °C to +125 °C same), higher noise (11 nV/√Hz). | Preferred for battery-powered portable audio where ultra-low quiescent current (600 µA/ch) is prioritized over drive strength. | Choose when power budget is constrained and load impedance >1 kΩ - avoid for 600 Ω headphone or actuator drive. |
Compared with LM324DT and TLV2464CDR, TS9224IDT uniquely balances 80 mA drive, 4 MHz bandwidth, rail-to-rail operation, and AEC-Q100 qualification - making it the only option among the three for automotive servo and high-fidelity line-driver applications demanding both precision and robustness.

FAQ
Is TS9224IDT qualified for automotive applications?
Yes, TS9224IDT is AEC-Q100 qualified for Grade 1 (−40 °C to +125 °C) operation and features HBM ESD protection rated at 3 kV. Its electrical specifications - including input offset drift (2 µV/°C), latch-up immunity, and thermal resistance (66 °C/W in SO14) - are validated per automotive reliability standards and widely deployed in engine control, ADAS sensor interfaces, and infotainment systems.
Can TS9224IDT drive a 500 pF capacitive load without external compensation?
Yes, the TS9224IDT is explicitly characterized for stable operation with up to 500 pF capacitive loads at unity gain, as confirmed in Figure 4 of the datasheet (phase margin ≥60°). This eliminates the need for series isolation resistors in ADC driver, cable interface, or filter applications - reducing bill-of-materials and layout complexity while preserving signal integrity.
What is the maximum output current per channel, and how does it behave under short-circuit conditions?
Each channel delivers up to 80 mA continuous output current into resistive loads and sustains short-circuit currents of 50–80 mA depending on supply voltage, as specified in Table 3 and Table 4. There is no internal short-circuit protection - sustained output shorts require external current limiting or thermal monitoring to prevent junction temperature exceeding 150 °C, especially in multi-channel simultaneous fault conditions.
Does TS9224IDT support single-supply operation with rail-to-rail input and output?
Yes, TS9224IDT operates from a single 2.7–12 V supply with rail-to-rail input common-mode range (VCC− −0.2 V to VCC+ +0.2 V) and rail-to-rail output swing (within 50 mV of rails at 10 kΩ load). This allows direct interfacing with unipolar sensors and microcontroller ADCs without level-shifting circuitry - simplifying design in battery-powered and automotive systems.
