Product details

Overview

TS9222IDT 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 stable operation with capacitive loads up to 500 pF - enabling direct drive of low-impedance audio and actuator circuits.

For engineers reviewing the TS9222IDT datasheet, TS9222IDT pinout, TS9222IDT application, or TS9222IDT equivalent, key selection criteria include rail-to-rail output swing at 2.7–12 V supply, 80 mA output current capability, low 9 nV/√Hz input noise, and AEC-Q100-compliant automotive qualification (−40°C to +125°C).

Technical Context

The TS9222IDT integrates two independent precision op-amps in a single SO8 package, each featuring fully rail-to-rail input common-mode range (V_CC− − 0.2 V to V_CC+ + 0.2 V) and rail-to-rail output swing (within 50 mV of rails at 600 Ω load). Its internal architecture ensures stability without external compensation when driving capacitive loads ≤500 pF.

It operates across 2.7–12 V single-supply or ±1.35–±6 V dual-supply configurations, with 65–85 dB CMRR and 70–90 dB PSRR over temperature. Input offset drift is specified at 2 µV/°C, supporting precision DC-coupled applications such as sensor front-ends and servo control loops.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.7 V to 12 V - supports wide-input industrial and automotive battery-sourced systems without LDO pre-regulation.
Gain Bandwidth Product	4 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 at >300 kHz for anti-aliasing or active filtering.
Slew Rate	1.3 V/μs - sustains 2 V_PP output at 100 kHz with <0.005% THD into 600 Ω, suitable for line-level audio drivers.
Input Offset Voltage	≤500 µV (max) - reduces DC error in 12-bit+ data acquisition paths without trimming or auto-zero circuitry.
Output Current	80 mA (short-circuit) - drives 600 Ω headphones, 1 kΩ actuators, or 100 pF + 10 kΩ RC networks directly.
Input Noise Density	9 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouple, bridge transducers).
Capacitive Load Drive	Stable up to 500 pF - eliminates need for isolation resistors when interfacing with ADC input capacitance or long PCB traces.

Pinout & Package

TS9222IDT is supplied in an SO8 (Small Outline 8-pin) package per JEDEC MS-012, with 1.27 mm pitch, 4.90 mm × 6.00 mm body, and 1.75 mm height. Thermal resistance R_thJA = 125 °C/W (SO8, still air).

Pin	Circuit Role	Design Meaning
1	Inverting input (Amp 1)	High-impedance node for feedback network connection; supports DC-coupled differential or inverting configurations.
2	Non-inverting input (Amp 1)	Accepts rail-to-rail common-mode signals down to V_CC− − 0.2 V, enabling ground-referenced sensor interfaces.
3	Output (Amp 1)	Delivers rail-to-rail swing with 80 mA sourcing/sinking; stable into 500 pF + resistive load combinations.
4	V_CC−	Negative supply rail or ground reference; must be decoupled locally with ≥100 nF ceramic capacitor.
5	Non-inverting input (Amp 2)	Independent input for second channel; identical specs to Pin 2 - enables dual-path signal processing.
6	Inverting input (Amp 2)	Matches Pin 1 electrical behavior; supports matched gain-setting resistor networks across both channels.
7	Output (Amp 2)	Electrically isolated from Amp 1 output; allows simultaneous drive of separate loads (e.g., left/right audio).
8	V_CC+	Positive supply rail; accepts 2.7–12 V; internal ESD protection rated to 2 kV HBM on all pins.

Key Features

Feature	Design Value
Rail-to-rail I/O	Enables full dynamic range utilization in low-voltage (2.7 V) single-supply systems without level-shifting circuitry.
500 pF capacitive load stability	Eliminates external series resistors when driving ADC inputs, display bias networks, or long cables - reducing BOM count.
80 mA output current	Directly drives 600 Ω headphones or 1 kΩ actuators without external buffers, simplifying analog output stages.
9 nV/√Hz input noise	Maintains >90 dB SNR in 20 kHz bandwidth for microphone preamps or strain-gauge amplifiers without post-amplification noise penalty.
AEC-Q100 qualified	Rated for −40°C to +125°C operation with enhanced ESD (2 kV HBM) and latch-up immunity - validated for under-hood automotive use.

Use Scenario: Driving stereo 600 Ω headphones from a DAC output in infotainment head units.

IC Role / Device Role / Timing Role: Rail-to-rail output buffer with 1.3 V/μs slew rate, delivering 2 V_PP at 20 kHz with <0.005% THD.

Use Value: 80 mA output current and 500 pF stability eliminate external output coupling capacitors and isolation resistors.

Industrial Line Driver

Servo Motor Feedback Amplifier

Use Scenario: Transmitting analog process signals (4–20 mA loop-derived voltage) over 100 m twisted-pair cables to PLC inputs.

IC Role / Device Role / Timing Role: Low-distortion unity-gain buffer with 120 dB channel separation, isolating source from cable capacitance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual precision rail-to-rail op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2462IDR	Lower supply range (2.7–6 V), 6.4 MHz GBW, but only 50 mA output current and no AEC-Q100 rating.	Not qualified for automotive under-hood use; limited to ≤6 V industrial systems.	Select when higher speed is needed at lower supply voltage and automotive qualification is unnecessary.
OPA2333AIDR	Zero-drift architecture (0.02 µV/°C drift), 350 kHz GBW, 25 mA output, 1.8–5.5 V supply.	Superior DC precision but insufficient bandwidth and output drive for audio or actuator applications.	Select for ultra-low-drift sensor front-ends where bandwidth <500 kHz and load <10 kΩ are acceptable.

Compared with TLV2462IDR and OPA2333AIDR, TS9222IDT uniquely balances automotive-grade reliability, 80 mA output drive, 4 MHz bandwidth, and rail-to-rail operation across 2.7–12 V - making it optimal for dual-channel analog signal chains requiring robustness and versatility.

FAQ

Is TS9222IDT qualified for automotive applications?

Yes. TS9222IDT carries AEC-Q100 qualification for Grade 1 (−40°C to +125°C ambient), with enhanced ESD protection (2 kV HBM), latch-up immunity, and production testing per automotive reliability standards. It is explicitly listed in ST's ordering table as automotive-grade (TS9222IYDT variant), and its datasheet highlights "automotive applications" in Features and Applications sections.

Can TS9222IDT drive a 32 Ω headphone load?

No - while TS9222IDT delivers 80 mA short-circuit current, its output stage is not optimized for sustained 32 Ω loads. Datasheet THD+noise plots show rapid degradation below 100 Ω (e.g., 0.7% THD at 32 Ω, 2 V_PP, 1 kHz). It is specified and characterized for 600 Ω and higher loads; for 32 Ω, dedicated audio amplifier ICs (e.g., TPA6130A2) are recommended.

What is the maximum capacitive load TS9222IDT can drive without oscillation?

TS9222IDT is guaranteed stable with capacitive loads up to 500 pF when driving purely capacitive or RC loads (e.g., 500 pF || 10 kΩ). This is verified in Figures 4 and 7 of the datasheet, showing phase margin ≥60° at unity gain with 500 pF. Exceeding 500 pF requires external isolation resistance or feedback compensation per application note AN2717.

Does TS9222IDT require external compensation capacitors?

No. TS9222IDT is internally compensated for unity-gain stability and does not require external compensation capacitors. Its design ensures ≥60° phase margin with 100 pF load (Figure 3) and ≥60° with 500 pF load (Figure 4), eliminating the need for external capacitors in standard gain configurations - simplifying layout and reducing component count.
