Product details
Overview
TSX562IQ2T from STMicroelectronics is a dual-channel, micropower, rail-to-rail input CMOS operational amplifier optimized for high-impedance sensor interfaces and automotive signal conditioning. It delivers 900 kHz gain bandwidth at 250 µA per channel (16 V), 600 µV max offset voltage (A-grade), 1 pA typical input bias current, and operates across –40 °C to +125 °C in DFN8 2 mm × 2 mm package.
For engineers reviewing the TSX562IQ2T datasheet, TSX562IQ2T pinout, TSX562IQ2T application, or TSX562IQ2T equivalent, this page provides verified electrical specifications, thermal performance data, rail-to-rail input behavior, ESD robustness (4 kV HBM), and real-world design implications for industrial and automotive analog front-ends.
Technical Context
The TSX562IQ2T uses complementary PMOS/NMOS input stages enabling rail-to-rail input common-mode range from (VCC–) –0.1 V to (VCC+) +0.1 V, with full performance maintained up to (VCC+) –1.5 V. Its 900 kHz GBP and 1.1 V/µs slew rate support stable active filtering and precision DC-coupled amplification.
It features 76 dB min CMRR at 16 V, 90 dB min PSRR, and low 15 µVPP (0.1–10 Hz) input noise - critical for thermocouple, strain gauge, and medical sensor signal chains where offset drift (2–12 µV/°C) and long-term stability (1.6 nV/√month) directly impact measurement accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3 V to 16 V - supports direct interfacing with 3.3 V microcontrollers and 12 V automotive rails without level-shifting. |
| Gain Bandwidth Product | 900 kHz typ. at 16 V - enables stable unity-gain buffers and 2nd-order active filters up to ~100 kHz with <5° phase margin degradation. |
| Input Offset Voltage | 600 µV max (TSX562A grade) - ensures ≤0.012% error in 5 V full-scale 16-bit ADC systems at room temperature. |
| Input Bias Current | 1 pA typ. - preserves signal integrity in >1 GΩ source impedance applications (e.g., pH electrodes, piezoelectric sensors). |
| Common-Mode Rejection | 72 dB min over –40 to +125 °C - maintains accuracy in noisy industrial environments with ground shifts up to ±200 mV. |
| ESD Robustness | 4 kV HBM - eliminates need for external protection diodes in automotive body control modules and under-hood ECUs. |
| Thermal Resistance | 120 °C/W (DFN8 2×2) - allows 250 µA/channel operation at 125 °C ambient with <15 °C junction rise under no airflow. |
Pinout & Package
TSX562IQ2T is housed in a wettable flank DFN8 2 mm × 2 mm package (pitch = 0.5 mm), qualified for reflow soldering and automated optical inspection. Exposed thermal pad improves power dissipation and reduces θJA to 120 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+ A) | Non-inverting input, Channel A | Rail-to-rail capable; accepts signals from –0.1 V to VCC + 0.1 V - enables single-supply sensor biasing without external level shifters. |
| 2 (IN– A) | Inverting input, Channel A | High-impedance node (1 pA bias); requires guard ring layout to prevent leakage-induced offset in PCBs with humidity exposure. |
| 3 (V–) | Negative supply rail | Ground reference for dual-supply use or 0 V return in single-supply configurations; must be decoupled with 10 nF capacitor. |
| 4 (OUT A) | Amplified output, Channel A | Drives loads ≥10 kΩ; delivers ±40 mA sink/source at 16 V - sufficient for driving SAR ADC reference buffers or LED bias circuits. |
| 5 (OUT B) | Amplified output, Channel B | Independent output stage; allows dual-path signal conditioning (e.g., differential input + reference buffer) without crosstalk. |
| 6 (IN– B) | Inverting input, Channel B | Matched to Pin 2; supports matched gain-setting resistors for differential amplifiers with <0.1% ratio drift over temperature. |
| 7 (IN+ B) | Non-inverting input, Channel B | Electrically identical to Pin 1; enables true dual-channel instrumentation front-end with shared VREF routing. |
| 8 (V+) | Positive supply rail | Accepts 3–16 V; internal UVLO prevents latch-up during cold-cranking transients (e.g., 6 V dips in 12 V automotive systems). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with phase-reversal immunity | Prevents output inversion when inputs exceed (VCC+) –1.5 V - critical for overvoltage-tolerant sensor diagnostics in ISO 16750-compliant ECUs. |
| Automotive-grade temperature range | Guaranteed operation from –40 °C to +125 °C ambient - meets AEC-Q100 Grade 1 requirements for engine control and transmission modules. |
| Low 15 µVPP 0.1–10 Hz noise | Enables sub-1 µV resolution in DC-coupled medical ECG front-ends without external chopper stabilization or digital post-processing. |
| 1.6 nV/√month long-term VIO drift | Supports 15-year field life in industrial process controllers where calibration intervals exceed 5 years and drift must remain <10 µV. |
| ECOPACK®2 RoHS/REACH-compliant packaging | DFN8 wettable flank enables automated solder-joint inspection - reduces field failure risk in high-reliability automotive production lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSX562IST | Same die, MiniSO8 package (190 °C/W θJA, larger footprint, no wettable flanks) | Better suited for prototyping and manual rework; lacks automated AOI compatibility of DFN8 | Select when board space permits and optical solder inspection is not required. |
| MCP6022-E/SN | Lower GBP (1 MHz), higher IIB (100 pA), no A-grade VIO option, wider VCC (2.7–6 V only) | Limited to low-voltage consumer electronics; unsuitable for 12 V automotive or industrial 16 V rails | Choose only for cost-sensitive 3.3 V IoT sensor nodes where 1 mV VIO is acceptable. |
Compared with TSX562IST, TSX562IQ2T offers superior thermal performance and automated assembly readiness; versus MCP6022-E/SN, it enables higher-voltage, lower-drift, and automotive-qualified designs - making it the sole choice for AEC-Q100-compliant dual-channel signal chains.

FAQ
What is the maximum capacitive load the TSX562IQ2T can drive while maintaining stability?
The TSX562IQ2T remains stable with up to 100 pF capacitive load at unity gain, as confirmed by phase margin ≥55° in Figure 13 of the datasheet. For loads >100 pF, a 10 Ω isolation resistor in series with the output is required to preserve stability - a standard practice in ADC driver and cable-driving applications.
Does the TSX562IQ2T support true rail-to-rail output swing?
No - the TSX562IQ2T features rail-to-rail *input* only. Its output swings to within 70 mV of each rail (VOH/VOL = 70 mV) under 10 kΩ load, as specified in Tables 4–6. This is sufficient for driving 24-bit SAR ADC references but not for direct LED or MOSFET gate driving without level-shifting.
Can TSX562IQ2T operate from a single 3.3 V supply with input signals near ground?
Yes - its input common-mode range extends to (VCC–) –0.1 V, allowing direct connection of 0 V-referenced sensors (e.g., thermocouples, RTDs) without negative supply or level-shifting circuitry. Output remains functional down to 70 mV above ground, enabling accurate low-side current sensing.
Is the DFN8 package of TSX562IQ2T compatible with standard reflow profiles?
Yes - the DFN8 2×2 mm package is qualified for JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Its wettable flank design supports automated optical inspection of solder fillets, and the exposed thermal pad must be connected to a minimum 25 mm² copper pour for optimal thermal performance.
