Product details
Overview
TSB711ILT 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, and operates from 2.7 V to 36 V single supply (±1.35 V to ±18 V dual). Its integrated EMI filter and 2 kV HBM ESD rating support robust operation in motor control and automotive-grade systems.
For engineers reviewing the TSB711ILT datasheet, TSB711ILT pinout, TSB711ILT application, or TSB711ILT equivalent, key selection criteria include its rail-to-rail input common-mode range (VCC− to VCC+ + 0.1 V), low 12 nV/√Hz input voltage noise at 10 kHz, −40 °C to +125 °C extended temperature operation, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The TSB711ILT employs a complementary NPN/PNP rail-to-rail input stage enabling full common-mode range operation while maintaining stable CMRR >110 dB over −40 °C to +125 °C. Its internal EMI filter suppresses RF rectification-induced offset shifts, critical for noisy industrial environments.
It features unity-gain-stable compensation with ≥45° phase margin at 36 V, supports capacitive loads up to 100 pF, and exhibits no phase reversal across its absolute maximum input voltage range (VCC− − 0.2 V to VCC+ + 0.2 V).

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 |
|---|---|---|---|
| TSB712ILT | Dual-channel version in MiniSO8; identical specs per channel but higher ICC (3.6 mA vs. 1.8 mA) | Preferred for multi-sensor systems requiring matched channel performance (e.g., 3-phase motor current sensing) | Select when board area allows MiniSO8 and dual-channel correlation matters more than quiescent power. |
| TSB511ILT | Same 36 V rating and rail-to-rail I/O, but lower 2.5 MHz GBP and 1.5 V/µs slew rate; 1.1 mA ICC | Better suited for low-power, lower-bandwidth applications like thermocouple amplification | Choose only if bandwidth <3 MHz suffices and supply current reduction is prioritized over speed/noise. |
Compared with TSB712ILT, the TSB711ILT saves PCB area and power in single-channel designs; versus TSB511ILT, it delivers 2.4× higher bandwidth and 2× faster slew rate at modest ICC increase-critical for real-time current control loops.

FAQ
What is the maximum capacitive load the TSB711ILT can drive stably?
The TSB711ILT is characterized for stable operation with up to 100 pF capacitive load at unity gain, maintaining ≥45° phase margin. For loads exceeding 100 pF, external isolation resistance (≥100 Ω) is required between output and capacitance to prevent peaking or oscillation, as confirmed in Figure 26 of DS12487 Rev 7.
Does the TSB711ILT support true rail-to-rail input at the positive rail?
Yes-the input common-mode range extends to VCC+ + 0.1 V, enabling operation with inputs at the positive supply. However, optimal CMRR (>115 dB) and minimal input offset drift are guaranteed only up to VCC+ − 1.5 V; operation near VCC+ may degrade CMRR by up to 25 dB due to PNP/NPN input stage transition.
How does the integrated EMI filter function in the TSB711ILT?
The EMI filter is an internal RC network at the input stage that attenuates RF signals above 10 MHz before they reach the differential pair, preventing rectification-induced DC offset shifts. Measured EMIRR exceeds 80 dB at 900 MHz, eliminating need for external ferrite beads or RC filters in typical industrial 433/868 MHz wireless environments.
Can the TSB711ILT be used as a comparator?
No-it is not designed or characterized for open-loop comparator operation. Input differential voltage must be limited to ±2 V to avoid excessive current through internal ESD diodes; sustained saturation may cause phase reversal outside the specified common-mode window and accelerate long-term offset drift beyond 0.57 µV/√month.
