Product details
Overview
TSX920ILT from STMicroelectronics is a single-channel rail-to-rail input/output CMOS operational amplifier optimized for high-speed, low-distortion signal conditioning in automotive and industrial systems. It delivers 10 MHz gain bandwidth, 17.2 V/µs negative slew rate, and 0.0003 % THD+N at 1 kHz with 4 V–16 V supply operation - enabling precision I/V conversion for ADC front-ends and active filtering in communications infrastructure.
For engineers reviewing the TSX920ILT datasheet, TSX920ILT pinout, TSX920ILT application, or TSX920ILT equivalent, this device supports rail-to-rail operation across extended temperature (−40 °C to +125 °C), features 10 pA input bias current and 4 kV HBM ESD tolerance, and includes shutdown control for power-sensitive embedded designs.
Technical Context
The TSX920ILT employs a CMOS input stage with unity-gain stability and internal compensation, supporting stable operation with capacitive loads up to 47 pF without external compensation. Its architecture enables full rail-to-rail swing at both inputs and output while maintaining 10 MHz bandwidth across 4–16 V supply range.
It integrates a dedicated SHDN pin (Pin 6) that reduces supply current to ≤15 µA per amplifier during inactive state, with turn-on time of 1.5 µs and turn-off time of 0.2 µs at 16 V - critical for duty-cycled sensor interfaces and battery-backed instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 10 MHz typ at 16 V - ensures stable closed-loop operation up to 100 kHz with gain ≥100. |
| Slew Rate (SR−) | 17.2 V/µs typ at 16 V - supports fast settling for 12-bit ADC sampling at ≥1 MSPS. |
| THD+N | 0.0003 % at 1 kHz, 4 Vrms out - preserves signal fidelity in audio and precision analog front-ends. |
| Input Bias Current | 10 pA typ - minimizes voltage error in high-impedance sensor interfaces (e.g., pH, photodiode). |
| ESD Tolerance | 4 kV HBM - meets automotive system-level robustness requirements without external protection. |
| Supply Voltage Range | 4 V to 16 V - compatible with 5 V, 12 V, and wide-input industrial rails without LDO pre-regulation. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and factory-floor process control environments. |
Pinout & Package
SOT23-6 package (2.9 mm × 2.8 mm × 1.3 mm), thermally enhanced for continuous operation at 125 °C ambient. Pin 1 = VCC+, Pin 2 = IN−, Pin 3 = OUT, Pin 4 = VCC−, Pin 5 = IN+, Pin 6 = SHDN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC+) | Positive supply rail | Accepts 4–16 V; internal overvoltage clamp limits to 18 V absolute max. |
| 2 (IN−) | Inverting input | Rail-to-rail common-mode range (VCC− −0.1 V to VCC+ +0.1 V) enables direct sensor connection. |
| 3 (OUT) | Amplifier output | Drives 2 kΩ load to within 150 mV of rails at 16 V - supports 12-bit DAC buffer applications. |
| 4 (VCC−) | Negative supply rail / ground reference | Typically connected to GND in single-supply configurations; supports true dual-supply operation. |
| 5 (IN+) | Non-inverting input | 1 TΩ input resistance and 8 pF capacitance minimize loading on high-Z sources. |
| 6 (SHDN) | Shutdown control input | Active-low logic: pulls to VCC− to reduce ICC to ≤15 µA; requires no external pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V–16 V systems without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911ILT | Lower GBP (8 MHz), lower supply current (1.1 mA), no shutdown pin | Better suited for always-on low-power sensor nodes; lacks SHDN for duty-cycled use cases | Select when power budget <1.5 mA and shutdown not required |
| LMV721IDBVR | Higher input offset (2.5 mV max), lower ESD (2 kV HBM), no automotive qualification | Limited to commercial-temperature consumer electronics; unsuitable for automotive or industrial field deployment | Select only for cost-sensitive non-automotive applications with relaxed accuracy and reliability |
Compared with TSV911ILT and LMV721IDBVR, the TSX920ILT uniquely combines automotive qualification, integrated shutdown, and 10 MHz bandwidth - making it the sole choice for safety-critical, power-gated, high-fidelity analog signal chains in harsh environments.

FAQ
What is the maximum capacitive load the TSX920ILT can drive without oscillation?
The TSX920ILT remains stable with capacitive loads up to 47 pF when configured in unity-gain follower mode with 10 kΩ load, as verified in Figure 20 of DS9502 Rev 5. For loads >47 pF, a series resistor (≥100 Ω) between output and capacitor is required to maintain phase margin >55°.
Does the TSX920ILT require external compensation for gain-of-10 operation?
No external compensation is needed for gains ≥1, including gain-of-10, due to internal unity-gain compensation. Figure 14 confirms >60° phase margin at 10 MHz with 10 kΩ load and 20 pF capacitance - meeting stability criteria per IEEE Std 1003.1.
How does shutdown mode affect output state?
During shutdown (SHDN = VCC−), the output enters high-impedance state - neither sourcing nor sinking current. This prevents back-driving of downstream circuitry and eliminates loading on shared analog buses in multi-amplifier systems.
Is the TSX920ILT pin-compatible with other SOT23-6 op amps like the LMV321?
No - TSX920ILT uses non-standard pinout: Pin 6 = SHDN, whereas LMV321 Pin 6 = NC or output. Swapping causes functional failure. Always verify pin mapping using Figure 1 in DS9502; no drop-in replacement exists without PCB redesign.
