Product details
Overview
TS9222ID from STMicroelectronics is a dual 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 TS9222ID datasheet, TS9222ID pinout, TS9222ID application, or TS9222ID equivalent, key selection criteria include rail-to-rail I/O swing, 80 mA output current capability, low 9 nV/√Hz input noise, and AEC-Q100-compliant operation across –40 °C to +125 °C.
Technical Context
The TS9222ID integrates two independent precision op-amps with unity-gain stable architecture, enabling direct driving of low-impedance loads (e.g., 600 Ω audio lines) without external compensation. Its input stage supports common-mode voltage from VCC– – 0.2 V to VCC+ + 0.2 V, and output swings within 50 mV of each rail under 10 kΩ load.
Designed for stability with capacitive loads, it maintains ≥60° phase margin at unit gain with 500 pF load and exhibits 120 dB channel separation - critical for dual-channel signal paths where crosstalk must be minimized in servo or actuator driver topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz - enables stable closed-loop operation up to ~300 kHz with gain = 10, suitable for anti-aliasing and active filter stages. |
| Slew Rate | 1.3 V/µs - supports full-scale 2 VPP output at 100 kHz without distortion in line-driver applications. |
| Input Offset Voltage | 500 µV max - ensures ≤0.05% gain error in 10-bit ADC front-end buffering with ±2.5 V input range. |
| Output Current | 80 mA - drives 600 Ω loads at ±2.5 V supply or 32 Ω headphones at ±1.5 V without clipping. |
| Input Noise Density | 9 nV/√Hz at 1 kHz - preserves SNR > 100 dB in 20 kHz audio band when gain = 10. |
| Supply Range | 2.7 V to 12 V - compatible with single-supply 3.3 V microcontroller I/O domains and dual ±5 V analog subsystems. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1, validated for under-hood automotive sensor signal conditioning. |
Pinout & Package
TS9222ID is supplied in an SO8 (Small Outline 8-pin) package with standard 1.27 mm pitch, 4.9 mm × 6.0 mm body, and 1.75 mm height - compliant with JEDEC MS-012 and RoHS/ECOPACK®2 requirements.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts feedback or inverted signal path; bias current ≤90 nA minimizes resistor-induced offset. |
| 2 | Non-inverting Input (Channel 1) | High-impedance node (Zin > 1012 Ω); rail-to-rail common-mode range supports ground-referenced sensors. |
| 3 | Output (Channel 1) | Delivers 80 mA short-circuit current; stable into 500 pF - eliminates need for isolation resistors in capacitive DAC buffers. |
| 4 | VCC– (Ground / Negative Supply) | Reference for dual-supply operation or ground return in single-supply mode; thermal resistance RθJA = 125 °C/W. |
| 5 | VCC+ (Positive Supply) | Accepts 2.7–12 V; internal ESD protection rated at 2 kV HBM ensures robustness during PCB handling and system integration. |
| 6 | Inverting Input (Channel 2) | Independent input stage; channel separation ≥120 dB prevents interference between differential sensor pairs. |
| 7 | Non-inverting Input (Channel 2) | Matches Channel 1 specs; enables matched dual-path designs like instrumentation amp pre-amps. |
| 8 | Output (Channel 2) | Full rail-to-rail swing (50 mV from rail @ 600 Ω); supports stereo headphone drive or dual-axis actuator control. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems - output reaches within 50 mV of VCC– and VCC+, input accepts signals down to VCC–. |
| Capacitive Load Drive | Stable with up to 500 pF load - eliminates external compensation in DAC output buffers and piezo driver interfaces. |
| Low Distortion | THD+N = 0.005 % at 1 kHz, 2 VPP, 600 Ω - meets Class AB audio line-driver requirements without post-filtering. |
| High Output Current | 80 mA per channel - directly drives 600 Ω lines, 32 Ω headphones, or low-side MOSFET gates without external buffers. |
| Automotive Qualification | AEC-Q100 Grade 1 certified - validated for continuous operation at 125 °C ambient in engine control modules and ADAS sensor nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2772IDR | Lower supply range (2.7–6 V), 2.5 MHz GBW, 1.1 V/µs SR, 1.25 mV Vio max - less precision, lower power (0.65 mA/ch). | Not qualified for automotive temp range; limited to commercial/industrial use below 85 °C. | Choose for cost-sensitive, low-voltage (<6 V), non-automotive systems where 1 mV offset is acceptable. |
| OPA2333AIDR | Zero-drift architecture, 0.01 µV/°C drift, 350 nV Vio max, but only 350 kHz GBW and 160 µA IQ/ch. | Superior DC accuracy but insufficient bandwidth for audio or fast servo loops requiring >1 MHz closed-loop response. | Prefer for ultra-low-drift DC measurement front-ends (e.g., weigh scales), not dynamic signal paths. |
Compared with TLV2772IDR and OPA2333AIDR, TS9222ID uniquely balances automotive-grade temperature range, 4 MHz bandwidth, rail-to-rail operation, and sub-millivolt offset - making it optimal for real-time analog signal chains in safety-critical embedded control.

FAQ
Is TS9222ID pin-compatible with other dual op-amps in SO8 packages?
No - TS9222ID follows a non-standard pinout: Pin 1 = In1–, Pin 2 = In1+, Pin 3 = Out1, Pin 4 = VCC–, Pin 5 = VCC+, Pin 6 = In2–, Pin 7 = In2+, Pin 8 = Out2. It is not pin-compatible with industry-standard dual op-amps like LM358 or TL072, which place VCC+ on Pin 8. Layout redesign is required for substitution.
Can TS9222ID drive a 32 Ω headphone load directly?
Yes - TS9222ID delivers 80 mA output current per channel and maintains THD+N ≤ 0.04 % at 4 VPP into 32 Ω at ±1.5 V supply (per Figure 8). Its rail-to-rail output swing allows full 3 VPP delivery from a 3.3 V single supply, making it suitable for compact headphone driver stages without external transistors.
What is the maximum capacitive load TS9222ID can drive without oscillation?
TS9222ID is specified stable with up to 500 pF capacitive load at unity gain (Figure 4), verified by ≥60° phase margin. Driving >500 pF requires external series resistance (typically 10–47 Ω) at the output to isolate the capacitive reactance from the op-amp's output impedance and restore stability.
Does TS9222ID require external compensation for unity-gain stability?
No - TS9222ID is internally compensated for unity-gain stability across its full operating range (2.7–12 V, –40 °C to +125 °C). No external capacitors or resistors are needed for stable operation at gain = 1, including with 500 pF loads. This simplifies layout and reduces BOM count in precision buffer applications.
