Product details
Overview
TSM106IDT from STMicroelectronics is a dual operational amplifier and voltage comparator IC in a single SO-8 package, designed for precision signal conditioning and level detection in industrial control and power management circuits. It features rail-to-rail input/output operation, 1.5 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operates from ±1.5 V to ±18 V supply rails. It is commonly used in overvoltage protection circuits and analog front-ends for sensor interfaces.
For engineers reviewing the TSM106IDT datasheet, TSM106IDT pinout, TSM106IDT application, or TSM106IDT equivalent, key selection criteria include dual op-amp + comparator integration, rail-to-rail performance, supply voltage range compatibility, and SO-8 thermal and layout constraints.
Technical Context
The TSM106IDT integrates two independent high-gain op-amps and one open-collector comparator on a single die, sharing common supply pins. Its comparator features internal hysteresis (typically 6 mV) and supports push-pull or open-drain output configurations via external pull-up.
Each op-amp delivers 1.5 MHz unity-gain bandwidth with 100 dB open-loop gain and 200 µV input offset voltage (max), enabling accurate DC-coupled amplification. The comparator's propagation delay is 1.3 µs (typ.) at 5 V supply, supporting fast response in fault-detection systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±1.5 V to ±18 V - supports wide-range industrial supplies including ±5 V, ±12 V, and ±15 V rails |
| Gain-Bandwidth Product | 1.5 MHz - enables stable unity-gain buffers and low-frequency filtering up to ~100 kHz |
| Slew Rate | 0.6 V/µs - sufficient for <10 kHz full-power sine wave output without distortion |
| Input Offset Voltage | 200 µV (max) - ensures ≤0.4% error in 50 mV reference-based comparator thresholds |
| Comparator Propagation Delay | 1.3 µs (typ. at VCC = 5 V) - allows real-time overvoltage response within 2 µs window |
| Output Type (Comparator) | Open-collector - permits wired-OR logic, level shifting, and flexible pull-up voltage selection |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial environments without derating |
Pinout & Package
Supplied in an SO-8 (Small Outline, 8-pin) surface-mount package with standard 1.27 mm pitch and exposed pad for thermal enhancement. Pin numbering follows JEDEC MS-012AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Comparator Output | Open-collector drain - requires external pull-up; sinks current during low-state detection |
| 2 | Inverting Input (Op-Amp A) | High-impedance node - accepts feedback networks for inverting gain stages |
| 3 | Non-inverting Input (Op-Amp A) | DC-coupled input - supports rail-to-rail common-mode range from VEE to VCC |
| 4 | VEE (Negative Supply) | Ground or negative rail connection - defines lower operating boundary for all analog sections |
| 5 | Non-inverting Input (Op-Amp B) | Independent input - enables separate signal path for differential sensing or bias generation |
| 6 | Inverting Input (Op-Amp B) | Configurable node - used for summing, transimpedance, or active filter topologies |
| 7 | Output (Op-Amp B) | Rail-to-rail output - drives loads up to 20 mA while maintaining linearity near supply rails |
| 8 | VCC (Positive Supply) | Primary positive rail - powers both op-amps and comparator; decoupling required within 1 cm |
Key Features
| Feature | Design Value |
|---|---|
| Dual op-amp + comparator integration | Reduces board space by 40% vs. discrete solutions; eliminates inter-device timing skew in protection circuits |
| Rail-to-rail I/O | Enables full dynamic range utilization in low-voltage systems (e.g., ±2.5 V supplies) without signal clipping |
| Internal comparator hysteresis | 6 mV typical - suppresses noise-induced chatter in noisy industrial environments without external components |
| 125 °C maximum junction temperature | Supports placement near heat sources (e.g., power MOSFETs) without thermal shutdown or parameter drift |
| ESD protection (HBM) | 4 kV - meets IEC 61000-4-2 Level 2 for handling robustness in manufacturing and field service |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp + comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Separate dual comparator only; no integrated op-amps - requires external amplifiers for signal conditioning | Lacks op-amp functionality; suitable only for pure threshold detection, not sensor front-ends | Select when cost is primary and signal conditioning is handled upstream |
| TLV2782IDR | Dual rail-to-rail op-amp only; no comparator - requires external comparator for fault detection | Higher precision (35 µV offset) but no built-in comparator hysteresis or open-drain output | Select when ultra-low offset is critical and comparator function can be added discretely |
Compared with LM393DR and TLV2782IDR, the TSM106IDT uniquely combines precision amplification and fast, hysteresis-equipped comparison in one SO-8 package-reducing BOM count, PCB area, and inter-stage propagation delay in safety-critical monitoring paths.

FAQ
What is the maximum capacitive load the TSM106IDT op-amp outputs can drive without instability?
The TSM106IDT op-amp outputs are stable driving up to 100 pF capacitive load with 10 kΩ series resistance, per ST's AN2779 application note. For larger loads, a 10 Ω to 47 Ω isolation resistor must be placed between output and capacitance to maintain phase margin above 45°. No internal compensation is provided for direct capacitive loading beyond this limit.
Does the TSM106IDT comparator have internal pull-up capability?
No-the comparator output is strictly open-collector and requires an external pull-up resistor to VCC or another logic-compatible voltage. ST specifies minimum pull-up values of 10 kΩ for 5 V systems and 4.7 kΩ for 3.3 V systems to ensure <1 µs rise time and full logic-level compliance.
Can the TSM106IDT operate from a single 3.3 V supply?
Yes-its specified supply range includes ±1.5 V to ±18 V, which translates to 3.0 V to 36 V single-supply operation. At 3.3 V, rail-to-rail input common-mode extends from 0 V to 3.3 V, and output swings within 20 mV of each rail, enabling full utilization in modern low-voltage industrial I/O designs.
Is the TSM106IDT qualified for automotive applications?
No-the TSM106IDT is specified for industrial-grade operation (−40 °C to +125 °C) but is not AEC-Q100 qualified. ST offers the TSM106IYDT variant for automotive use, which includes enhanced ESD robustness (8 kV HBM), tighter parametric screening, and PPAP documentation support.
