Product details
Overview
TSB512IDT from STMicroelectronics is a dual-channel rail-to-rail input/output operational amplifier optimized for high-side and low-side current sensing, motor control, and industrial process control. It operates from 2.7 V to 36 V single supply (or ±1.35 V to ±18 V dual), delivers 6 MHz gain bandwidth, 3 V/µs slew rate, and 12 nV/√Hz input voltage noise, with 1.5 mV max input offset voltage over temperature.
For engineers reviewing the TSB512IDT datasheet, TSB512IDT pinout, TSB512IDT application, or TSB512IDT equivalent, key selection criteria include its extended -40 °C to +125 °C operating range, integrated EMI filter, 2 kV HBM ESD tolerance, and SO8 package compatibility with high-voltage industrial signal conditioning designs.
Technical Context
The TSB512IDT implements a dual-channel CMOS op-amp architecture supporting wide common-mode input range (VCC− to VCC+ + 0.1 V) and rail-to-rail output swing within 90 mV of rails at 2 mA load. Its unity-gain-stable design achieves 45° phase margin with 100 pF capacitive load at 36 V supply.
It features matched channel performance with 125 dB crosstalk rejection at 1 kHz, <2 µV/°C input offset drift, and PSRR >100 dB across 10 Hz–100 kHz - enabling precision DC-coupled amplification in noisy industrial environments without external filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 36 V single supply - supports direct interfacing with 24 V industrial buses and 3.3/5 V logic without level-shifting. |
| Gain Bandwidth Product | 6 MHz - enables stable closed-loop operation up to ~500 kHz with moderate gain (e.g., G = 12), suitable for fast current loop feedback. |
| Slew Rate | 3 V/µs - ensures ≤330 ns rise time for 1 V step, critical for accurate pulse-width modulation (PWM) current sensing in motor drives. |
| Input Offset Voltage | ±1.5 mV max (25 °C), ±2 mV max (−40 °C to +125 °C) - minimizes baseline error in precision shunt-based current measurement. |
| Input Voltage Noise | 12 nV/√Hz @ 10 kHz - low enough to resolve µV-level signals from strain gauges or Hall sensors without dominating system noise floor. |
| Common-Mode Rejection | 85 dB min (−40 °C to +125 °C) - rejects supply ripple and ground bounce in high-side sensing configurations with floating inputs. |
| ESD Tolerance | 2 kV HBM - meets IEC 61000-4-2 Level 2 requirements for robustness in factory automation equipment. |
Pinout & Package
TSB512IDT is housed in an 8-pin SO8 (Small Outline) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant footprint, and exposed pad optional for thermal enhancement. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - rail-to-rail capable, drives loads down to 10 kΩ while maintaining linearity. |
| 2 | IN1− | Inverting input of Channel 1 - high-impedance node (IIB ≤ 100 nA) for differential sensing or feedback networks. |
| 3 | IN1+ | Non-inverting input of Channel 1 - accepts common-mode voltages up to VCC+ + 0.1 V, enabling high-side current monitor biasing. |
| 4 | VCC− | Negative supply terminal - referenced to system ground in single-supply mode; must be decoupled with ≥100 nF ceramic capacitor. |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs; supports independent sensor interfaces. |
| 6 | IN2− | Inverting input of Channel 2 - matched offset and bias characteristics to IN1− for consistent dual-channel performance. |
| 7 | OUT2 | Output of Channel 2 - identical AC/DC specs to OUT1; enables simultaneous monitoring of two current paths or sensor axes. |
| 8 | VCC+ | Positive supply terminal - accepts up to +40 V absolute max; requires local 100 nF + 10 µF bulk decoupling for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in single-supply systems - e.g., 0–24 V bus sensing with 3.3 V ADC interface. |
| Integrated EMI filter | Reduces susceptibility to 100 MHz–1 GHz RF interference without external RC filters, critical for motor drive PCB layouts. |
| Extended temperature range | Specified from −40 °C to +125 °C ambient - qualified for under-hood automotive and industrial cabinet applications. |
| Low input bias current | ≤100 nA at 25 °C - preserves accuracy in high-impedance transducer interfaces (e.g., pH electrodes, thermopiles). |
| High PSRR & CMRR | ≥100 dB PSRR and ≥85 dB CMRR over full temp range - maintains gain accuracy despite supply fluctuations or ground shifts. |
Applications
| High-Side Current Sensing | Motor Control Feedback |

Use Scenario: Monitoring phase current in a 24 V BLDC motor driver using a 5 mΩ shunt resistor placed between MOSFET source and ground. IC Role / Device Role / Timing Role: Amplifies differential voltage across shunt with G = 100, rejecting common-mode bus voltage up to 24 V while delivering rail-to-rail output to 12-bit SAR ADC. Use Value: Achieves ±0.5% full-scale current measurement accuracy over temperature due to low offset drift and high CMRR. |
Use Scenario: Closed-loop speed regulation in a servo amplifier where back-EMF and hall sensor outputs require simultaneous conditioning before MCU sampling. IC Role / Device Role / Timing Role: Dual-channel configuration processes hall sensor analog outputs (IN1±, IN2±) with matched gain and phase response to preserve commutation timing integrity. Use Value: 3 V/µs slew rate and 6 MHz bandwidth ensure <1 µs group delay mismatch between channels, preventing torque ripple. |
| Industrial Process Transmitter | Hall Effect Sensor Interface |
|
Use Scenario: 4–20 mA loop-powered transmitter converting RTD or pressure bridge output into standardized current signal. IC Role / Device Role / Timing Role: First-stage instrumentation amplifier (G = 100) with rail-to-rail output driving a voltage-to-current converter stage powered from same 24 V loop supply. Use Value: Wide 2.7–36 V supply range eliminates need for separate LDO; low noise preserves resolution in sub-0.1% accuracy systems. |
Use Scenario: Linear Hall effect sensor (e.g., HAL 506) output amplification in an automotive throttle position module. IC Role / Device Role / Timing Role: Single-supply amplifier biased at mid-rail to condition ratiometric Hall output (0.5–4.5 V) for 3.3 V microcontroller ADC input. Use Value: Integrated EMI filter suppresses ignition noise; 125 °C rating supports placement near engine manifold without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB712 | Higher precision: ±0.3 mV max VIO, 0.5 µV/°C drift, but narrower 3.3–36 V supply range and no integrated EMI filter. | Better suited for lab-grade instrumentation; less robust in electrically noisy motor control enclosures. | Select when offset-critical DC accuracy outweighs EMI immunity and extended low-voltage operation. |
| LM358DR | Lower cost, wider temp range (−40 °C to +125 °C), but limited 32 V max supply, 700 kHz GBP, 0.3 V/µs slew rate, and no rail-to-rail output. | Adequate for basic industrial monitoring where bandwidth and output swing are not limiting. | Choose only if system bandwidth <100 kHz and output headroom >1.5 V is acceptable. |
Compared with TSB512IDT, TSB712 offers superior DC precision at the expense of EMI resilience and low-voltage startup capability, while LM358DR trades bandwidth, noise, and rail-to-rail performance for cost and legacy compatibility - making TSB512IDT the balanced choice for modern 24 V industrial signal chains.
