Product details
Overview
TSB711IYLT from STMicroelectronics is a precision rail-to-rail input/output operational amplifier optimized for high-side and low-side current sensing, Hall effect sensor signal conditioning, and industrial instrumentation. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, 300 µV max input offset voltage at 25 °C, 12 nV/√Hz input voltage noise, and operates from 2.7 V to 36 V single supply - enabling accurate DC-coupled amplification in motor control feedback loops.
For engineers reviewing the TSB711IYLT datasheet, TSB711IYLT pinout, TSB711IYLT application, or TSB711IYLT equivalent, this device is selected for precision analog front-ends requiring extended common-mode range (VCC− to VCC+ + 0.1 V), EMI-hardened performance, and automotive-grade temperature stability (−40 °C to +125 °C) without external compensation.
Technical Context
The TSB711IYLT employs a complementary bipolar input stage with dual NPN/PNP differential pairs to achieve true rail-to-rail input operation across its full −40 °C to +125 °C operating range. Its input common-mode range extends to VCC+ + 0.1 V, though optimal CMRR (>115 dB) and offset stability are maintained within VCC− to VCC+ − 1.5 V.
It integrates on-die EMI filtering to suppress RF rectification effects, supports capacitive loads up to 100 pF while maintaining ≥45° phase margin, and features 2 kV HBM ESD tolerance. The amplifier is internally compensated for unity-gain stability with no external components required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz - enables stable closed-loop operation up to ~500 kHz with gain ≥12 in current-sense applications. |
| Slew Rate | 3 V/µs - supports fast transient response in motor control feedback paths without distortion. |
| Input Offset Voltage | ±300 µV max at 25 °C - ensures ≤0.3% error in 100 mV full-scale current-sense outputs. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - preserves SNR in strain gauge and Hall sensor interfaces with <100 Hz bandwidth. |
| Supply Voltage Range | 2.7 V to 36 V single supply - eliminates need for level-shifting in 12 V/24 V industrial bus systems. |
| Common-Mode Range | VCC− to VCC+ + 0.1 V - allows direct connection to shunt resistors placed on high-side or low-side of power rails. |
| EMI Rejection | Integrated filter - reduces RF-induced offset shift in noisy factory environments (e.g., near VFDs). |
Pinout & Package
SOT23-5 package: compact 2.9 mm × 1.6 mm surface-mount outline with exposed pad for thermal enhancement; rated RthJA = 250 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Amplifier output | Capable of sourcing/sinking ≥20 mA; rail-to-rail swing enables full dynamic range utilization. |
| 2 VCC− | Negative supply terminal | Reference node for dual-supply operation; connects to ground in single-supply configurations. |
| 3 IN+ | Non-inverting input | High-impedance node (IIB ≤ 300 nA); accepts signals from resistive transducers or Hall sensors. |
| 4 IN− | Inverting input | Used for feedback in transimpedance or difference-amplifier topologies; supports ±2 V differential input. |
| 5 VCC+ | Positive supply terminal | Accepts up to +40 V absolute max; internal protection diodes limit input overvoltage current to 10 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 0–VCC output swing and input operation down to VCC−, critical for single-supply shunt monitoring. |
| Low offset drift | 2.8 µV/°C max - limits temperature-induced error to <0.25 mV over −40 °C to +125 °C in precision current measurement. |
| Integrated EMI filter | Reduces RF-induced offset shift by >40 dB vs. unfiltered op-amps, validated per IEC 61000-4-3. |
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - qualified for engine control, battery management, and ADAS sensor interfaces. |
| High PSRR/CMRR | 125 dB PSRR and 130 dB CMRR at DC - rejects supply ripple and common-mode noise in noisy industrial power domains. |

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 |
|---|---|---|---|
| TSB511ILT | Same 36 V rating and rail-to-rail I/O, but lower GBP (6 MHz → 2.5 MHz) and higher offset (±1.5 mV). | Better suited for low-power sensor nodes where bandwidth <100 kHz suffices and quiescent current (0.9 mA vs. 1.8 mA) is critical. | Select when supply current budget is <1 mA and 2.5 MHz bandwidth meets loop response requirements. |
| TSB712IYST | Dual-channel version in MiniSO8; identical per-channel specs but shares supply pins and thermal resistance (190 °C/W). | Preferred for space-constrained dual-sensor systems (e.g., dual-axis current sensing) where layout area must be minimized. | Choose when two matched amplifiers are needed and board area permits MiniSO8 footprint. |
Compared with TSB511ILT, TSB711IYLT provides 2.4× higher bandwidth and 5× lower offset for demanding current sensing; versus TSB712IYST, it offers superior thermal performance (250 vs. 190 °C/W) in single-channel high-power-density designs.

FAQ
What is the maximum capacitive load the TSB711IYLT can drive while maintaining stability?
The TSB711IYLT is characterized for stable operation with up to 100 pF capacitive load at unity gain, delivering ≥45° phase margin per Figure 25 and Figure 26 in DS12487. Driving larger loads requires external isolation resistor (≥100 Ω) in series with the output to preserve stability, especially when sourcing ≥10 mA.
Does the TSB711IYLT require external compensation components?
No - the TSB711IYLT is internally compensated for unity-gain stability across its full supply range (2.7 V to 36 V) and temperature range (−40 °C to +125 °C). No external capacitors or resistors are needed for stable operation in standard inverting/non-inverting configurations.
How does the integrated EMI filter function, and what frequencies does it suppress?
The EMI filter is implemented as on-die RC networks at both inputs, attenuating RF energy above 10 MHz before it reaches the input transistors. It reduces offset voltage shift induced by 100–2000 MHz carrier signals (e.g., GSM, Wi-Fi) by >30 dB, as verified per IEC 61000-4-3 testing in the datasheet.
Can the TSB711IYLT operate with inputs beyond the supply rails, and what protection exists?
Yes - the inputs tolerate voltages from (VCC−) − 0.2 V to (VCC+) + 0.2 V per absolute maximum ratings. Internal ESD diodes clamp input overvoltage, but sustained current >10 mA must be limited externally using series resistors to prevent damage, as specified in Section 5.2 of the datasheet.
