Product details
Overview
TS9222IPT 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.
For engineers reviewing the TS9222IPT datasheet, TS9222IPT pinout, TS9222IPT application, or TS9222IPT equivalent, this device is selected for low-noise (9 nV/√Hz), high-output-current (80 mA) analog stages where rail-to-rail swing, stability with capacitive loads, and AEC-Q100-compliant performance are required.
Technical Context
The TS9222IPT implements a fully differential input stage with rail-to-rail common-mode 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 - critical for driving cables or ADC input filters without oscillation.
It features 85 dB typical CMRR and 90 dB typical PSRR across 2.7–12 V supply range, enabling robust operation in noisy automotive power domains. The 2 µV/°C input offset drift and 0.005% THD at 1 kHz support precision DC-coupled and audio-frequency signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz - supports stable closed-loop gain ≥10 at 400 kHz, suitable for anti-aliasing and active filtering. |
| Slew Rate | 1.3 V/µs - enables full-scale 2 Vpp output at ≥650 kHz without distortion in unity-gain buffer configurations. |
| Input Offset Voltage | ≤500 µV max - reduces DC error in sensor front-ends and current-sense amplifiers without trimming. |
| Output Current | ±80 mA - drives 600 Ω loads directly (e.g., line drivers, headphone outputs) without external buffers. |
| Capacitive Load Drive | Up to 500 pF - eliminates need for isolation resistors when interfacing with ADC inputs or long PCB traces. |
| Supply Voltage Range | 2.7 V to 12 V - operates across single Li-ion (3.3 V), dual AA (3 V), and automotive 12 V battery rails. |
| Input Noise Density | 9 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and precision instrumentation amplifiers. |
Pinout & Package
TSSOP8 package: 3 mm × 4.4 mm, 0.65 mm pitch, 1.2 mm height, lead-free, ECOPACK® compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of Channel 1 | Accepts feedback network connection; referenced to VCC− for single-supply operation. |
| 2 | Non-inverting input of Channel 1 | Connects to sensor output or reference divider; rail-to-rail common-mode range supports 0 V to VCC. |
| 3 | Output of Channel 1 | Delivers ±80 mA; capable of sourcing/sinking into 600 Ω or 500 pF without instability. |
| 4 | VCC− (Ground / Negative Supply) | Reference node for single-supply (0 V) or split-supply (e.g., −1.5 V) configurations. |
| 5 | VCC+ (Positive Supply) | Accepts 2.7–12 V; internal ESD protection rated to 2 kV HBM ensures robustness in assembly and field use. |
| 6 | Inverting input of Channel 2 | Independent input stage; no crosstalk (120 dB channel separation) enables dual-path signal processing. |
| 7 | Non-inverting input of Channel 2 | Matches Channel 1 specs; allows matched gain-setting for differential pair or stereo applications. |
| 8 | Output of Channel 2 | Electrically isolated output; supports independent loading and termination per channel. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS9222ID | SO8 package (5.0 × 4.0 mm), higher thermal resistance (125 °C/W), identical electrical specs. | Preferred for through-hole prototyping or high-reliability industrial PCBs requiring larger solder joints. | Select when board space permits larger footprint and thermal management favors SO8 over TSSOP8. |
| MCP6022-E/SN | Lower GBW (10 MHz), higher Vio (2.5 mV max), lower output current (25 mA), same 2.7–5.5 V supply range. | Better for high-speed, low-voltage logic-level buffering; unsuitable for 12 V or high-current loads. | Choose only for cost-sensitive 3.3 V systems where 80 mA drive and 500 pF stability are not required. |
Compared with TS9222ID and MCP6022-E/SN, the TS9222IPT uniquely combines automotive-grade reliability, 12 V operation, 500 pF capacitive drive, and 80 mA output in a space-constrained TSSOP8 package - making it irreplaceable for compact, high-fidelity analog signal paths in harsh environments.

FAQ
Is TS9222IPT qualified for automotive applications?
Yes. TS9222IPT is explicitly qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) and features enhanced ESD protection (2 kV HBM), latch-up immunity, and validated operation across 2.7–12 V supply - meeting requirements for engine bay and cabin electronics.
Can TS9222IPT drive a 1000 pF load?
No. The datasheet specifies stable operation up to 500 pF. Driving 1000 pF may cause peaking or oscillation due to phase margin degradation; a series isolation resistor (e.g., 10–22 Ω) is required for loads exceeding 500 pF.
What is the maximum output voltage swing at 12 V supply?
At VCC+ = 12 V and VCC− = 0 V, the output swings from 50 mV above VCC− to 50 mV below VCC+, i.e., 0.05 V to 11.95 V with 10 kΩ load - confirmed by VOL/VOH specs in Table 3 and Table 4 of the datasheet.
Does TS9222IPT require external compensation?
No. It is internally compensated for unity-gain stability and remains stable with capacitive loads up to 500 pF without external components - verified in Figures 3 and 4 of the datasheet across 100 pF and 500 pF conditions.
