Product details
Overview
TSB511IYLT from STMicroelectronics is a single-channel rail-to-rail input/output operational amplifier optimized for high-side and low-side current sensing, Hall effect sensor signal conditioning, and motor control feedback loops. It delivers 6 MHz gain bandwidth, 3 V/µs slew rate, 1.5 mV max input offset voltage, 12 nV/√Hz input voltage noise, and operates from 2.7 V to 36 V single supply across –40 °C to +125 °C.
For engineers reviewing the TSB511IYLT datasheet, TSB511IYLT pinout, TSB511IYLT application, or TSB511IYLT equivalent, this part supports precision analog signal amplification in automotive-grade industrial systems where wide supply range, EMI robustness, and extended temperature stability are critical selection criteria.
Technical Context
The TSB511IYLT implements a bipolar-input op-amp architecture with integrated EMI filtering and 2 kV HBM ESD protection, enabling reliable operation in noisy motor drive and industrial power conversion environments. Its rail-to-rail input common-mode range (VCC– to VCC+ + 0.1 V) and output swing within 90 mV of rails at 2 mA load support full-scale signal utilization in low-voltage and high-voltage sensing topologies.
It maintains stable unity-gain operation with ≥34° phase margin into 100 pF capacitive loads and exhibits 100 dB PSRR and 105 dB CMRR at 25 °C - key for rejecting supply ripple and common-mode interference in current-shunt amplifier configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6 MHz - enables stable closed-loop gain up to ~100× at 60 kHz for anti-aliasing filter design and fast current loop response. |
| Slew Rate | 3 V/µs - supports ≤1.5 µs 10–90% rise time for 4.5 V step, critical for accurate pulse-width modulation (PWM) current reconstruction. |
| Input Offset Voltage | ±1.5 mV max - limits worst-case current-sense error to <0.15% at 100 mΩ shunt with 100× gain, meeting AEC-Q100 automotive accuracy requirements. |
| Supply Voltage Range | 2.7 V to 36 V single supply - allows direct interface with 3.3 V microcontrollers and 24 V industrial buses without level-shifting. |
| Input Voltage Noise | 12 nV/√Hz at 10 kHz - ensures <1 µVrms integrated noise over 100 kHz bandwidth, preserving resolution in µV-level Hall sensor outputs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial ambient conditions without derating. |
| EMI Filtering | Integrated - suppresses RF interference from switching power supplies and motor inverters without external RC filters. |
Pinout & Package
TSB511IYLT is housed in a SOT23-5 surface-mount package (3.0 × 2.8 × 1.3 mm), optimized for space-constrained PCB layouts in motor control modules and battery management systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Drives feedback network or ADC input; rail-to-rail swing supports full dynamic range utilization. |
| 2 (VCC–) | Negative supply terminal | Ground reference for single-supply operation; connects to system GND when using 2.7–36 V single rail. |
| 3 (IN+) | Non-inverting input | Accepts high-impedance sensor signals (e.g., Hall voltage); rail-to-rail common-mode range enables direct connection to shunt resistors. |
| 4 (IN–) | Inverting input | Configures closed-loop gain via external resistor network; matched input bias currents minimize offset drift. |
| 5 (VCC+) | Positive supply terminal | Accepts 2.7–36 V input; internal regulation ensures stable biasing across full voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables >99% signal swing utilization from 2.7 V to 36 V supply, maximizing ADC resolution in low-voltage and high-voltage sensing. |
| Low 1.5 mV offset | Reduces zero-current error in bidirectional current sensing to <±150 µA at 100 mΩ shunt, eliminating need for factory calibration. |
| 6 MHz bandwidth | Supports closed-loop bandwidth >100 kHz for real-time motor phase current control with minimal phase lag. |
| Integrated EMI filter | Attenuates 100 MHz–1 GHz noise from MOSFET switching without external components, reducing layout sensitivity and BOM count. |
| 2 kV HBM ESD rating | Meets IEC 61000-4-2 Level 3 requirements for industrial equipment, enabling robust handling during assembly and field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB711ILT | Lower offset (±125 µV max), higher GBP (10 MHz), but narrower supply range (2.7–24 V). | Better for ultra-precision DC measurements; unsuitable for 36 V industrial bus interfaces. | Select when offset-critical DC accuracy outweighs high-voltage compatibility. |
| LMV321IDBVR | Wider temp range (–40 °C to +125 °C), same SOT23-5 package, but lower GBP (1 MHz) and higher noise (27 nV/√Hz). | Cost-optimized for non-critical signal chains; insufficient bandwidth for PWM current reconstruction. | Choose only for low-speed sensor buffering where cost dominates performance requirements. |
Compared with TSB511IYLT, TSB711ILT trades supply voltage headroom for superior DC precision, while LMV321IDBVR sacrifices bandwidth and noise performance for lower unit cost - making TSB511IYLT the optimal balance for automotive and industrial current sensing where 6 MHz bandwidth, 36 V operation, and EMI resilience are mandatory.

FAQ
What is the maximum capacitive load the TSB511IYLT can drive stably?
The TSB511IYLT is characterized for stable unity-gain operation with up to 100 pF capacitive load, maintaining ≥34° phase margin per DS13885 Rev 1. Driving larger loads requires isolation resistance or external compensation; no internal compensation is provided beyond this specification.
Does TSB511IYLT support dual-supply operation?
Yes - the TSB511IYLT operates from ±1.35 V to ±18 V dual supplies, as confirmed in the datasheet's operating conditions table. Pin 2 (VCC–) serves as the negative rail, and Pin 5 (VCC+) as the positive rail, enabling symmetric biasing for AC-coupled sensor interfaces.
Is TSB511IYLT qualified for automotive applications?
Yes - the "Y" in TSB511IYLT denotes AEC-Q100 qualification per ordering information Table 8, with advanced screening per AEC-Q001/Q002. It meets automotive reliability, temperature, and ESD requirements for under-hood and chassis-mounted modules.
How does the integrated EMI filter function without external components?
The EMI filter is monolithically integrated within the die, consisting of on-chip RC networks that attenuate RF energy above 100 MHz before it reaches the input stage. This eliminates the need for external ferrite beads or RC filters while maintaining full DC–6 MHz signal integrity.
