Product details
Overview
TS9511ILT from STMicroelectronics is a single precision rail-to-rail input/output operational amplifier with 3 MHz gain bandwidth, 1 V/µs slew rate, 800 µV max input offset voltage, and operation from 2.7 V to 12 V supply. It delivers low-power performance (900 µA at 3 V) in an SOT23-5 package and is used in signal conditioning circuits for portable audio and automotive sensor interfaces.
For engineers reviewing the TS9511ILT datasheet, TS9511ILT pinout, TS9511ILT application, or TS9511ILT equivalent, key selection criteria include rail-to-rail I/O capability, precision offset drift (2 µV/°C), high PSRR (85 dB), and SOT23-5 thermal resistance (250 °C/W) for compact battery-powered designs.
Technical Context
The TS9511ILT employs a CMOS input stage enabling rail-to-rail common-mode input range (VDD − 0.2 V to VCC + 0.2 V) and rail-to-rail output swing within 80 mV of each rail under 600 Ω load. Its 3 MHz GBP and 1 V/µs slew rate support stable unity-gain buffer configurations in audio line drivers and DAC output stages.
Designed for wide-supply operation (2.7–12 V), it maintains 60–90 dB CMRR and 65–90 dB SVR across temperature (−40 °C to +125 °C), with 25 nV/√Hz input noise at 1 kHz and 0.01% THD at 10 kHz - critical for low-distortion portable headphone amplification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - supports stable closed-loop gain up to 10 at 300 kHz for anti-aliasing filters |
| Slew Rate | 1 V/µs - enables full-scale 2 Vpk-pk output at 100 kHz without distortion |
| Input Offset Voltage | 800 µV max - ensures ≤1.6 mV error in 2 V full-scale 12-bit DAC buffering |
| Supply Current | 900 µA at 3 V - allows continuous operation in 10-year coin-cell–powered sensors |
| Common-Mode Range | VDD − 0.2 V to VCC + 0.2 V - accepts inputs down to ground in single-supply systems |
| Output Swing | Within 80 mV of rails (600 Ω load) - delivers >95% of supply headroom to headphones or ADC drivers |
| PSRR | 85 dB - suppresses 3 V supply ripple to <15 µV at op-amp output |
Pinout & Package
TS9511ILT is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), with 250 °C/W junction-to-ambient thermal resistance and 0.95 mm pitch. Pin 1 is marked with a dot; device orientation follows standard SOT23-5 top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Non-inverting input | CMOS input accepting signals from 0.2 V below VDD to 0.2 V above VCC |
| 2 (IN−) | Inverting input | Differential pair node; input bias current ≤150 nA limits resistor selection in high-Z networks |
| 3 (V−) | Negative supply | Ground reference in single-supply mode; must be decoupled within 5 mm of pin |
| 4 (OUT) | Amplifier output | Capable of ±20 mA short-circuit current; drives 600 Ω loads to rail with <250 mV dropout |
| 5 (V+) | Positive supply | Accepts 2.7–12 V; internal ESD protection rated to 1 kV HBM on all pins |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV321IDBVR | Lower GBP (1 MHz), higher Vio (2.5 mV max), same SOT23-5 package | Not qualified for automotive temp range; limited to 0–70 °C commercial use | Select when cost sensitivity outweighs precision and temperature requirements |
| MCP6001T-I/OT | Lower supply current (100 µA), lower slew rate (0.6 V/µs), 1.6 mV Vio max | Optimized for ultra-low-power sensor nodes; insufficient for audio bandwidth | Prefer for battery life-critical sub-100 kHz sensing, not audio or fast DAC buffering |
Compared with LMV321IDBVR and MCP6001T-I/OT, TS9511ILT uniquely balances 3 MHz bandwidth, 800 µV offset, and −40 °C to +125 °C operation - making it the only choice among the three for automotive-grade audio line drivers requiring both speed and precision.

FAQ
What is the maximum output current capability of TS9511ILT?
The TS9511ILT provides ±20 mA short-circuit output current per the datasheet (Table 3 and Table 4). Under normal 600 Ω load conditions, it delivers rail-to-rail swing with ≤250 mV dropout. Continuous output current should be limited to ≤10 mA to maintain thermal stability in SOT23-5 at ambient temperatures above 85 °C.
Does TS9511ILT support single-supply operation down to 2.7 V?
Yes - TS9511ILT is fully specified for single-supply operation from 2.7 V to 12 V. Its rail-to-rail input range extends from VDD − 0.2 V to VCC + 0.2 V, and output swings within 80 mV of each rail into 600 Ω, enabling direct interfacing with 3.3 V or 5 V microcontroller ADCs without level-shifting circuitry.
Is TS9511ILT qualified for automotive applications?
The TS9511ILT variant is industrial-grade (−40 °C to +125 °C), while the TS9511IYLT variant is explicitly qualified to AEC-Q100 Grade 2. TS9511ILT is widely used in automotive subsystems such as body control modules and infotainment preamps but lacks formal AEC-Q100 certification; design-in requires customer-level qualification per application requirements.
How does TS9511ILT's 3 MHz GBP affect stability in unity-gain configuration?
TS9511ILT is unity-gain stable, with 58° phase margin and 12 dB gain margin at unit gain (RL = 10 kΩ, CL = 100 pF). Its internal compensation ensures stable operation without external feedback capacitors, even with capacitive loads up to 100 pF - critical for driving ADC inputs or long PCB traces in portable instrumentation.
