Product details
Overview
TSX562AIYST from STMicroelectronics is a dual-channel, micropower, rail-to-rail input CMOS operational amplifier with 900 kHz gain bandwidth product, 600 µV max input offset voltage (A-grade), 235 µA typical supply current at 5 V, and operation from 3 V to 16 V. It is qualified for automotive applications and housed in a DFN8 2 mm × 2 mm package, enabling high-precision sensor signal conditioning in space-constrained industrial and automotive systems.
For engineers reviewing the TSX562AIYST datasheet, TSX562AIYST pinout, TSX562AIYST application, or TSX562AIYST equivalent, key selection criteria include its A-grade offset voltage stability over temperature (±1.8 mV max from –40 °C to 125 °C), ultra-low input bias current (1 pA typ.), ESD tolerance (4 kV HBM), and compatibility with high-impedance transducers in battery-powered or thermally harsh environments.
Technical Context
The TSX562AIYST employs complementary PMOS/NMOS input stages to achieve rail-to-rail input common-mode range (–0.1 V to VCC + 0.1 V), with optimized performance across –0.1 V to VCC – 1.5 V. Its 900 kHz GBP and 1.1 V/µs slew rate support stable unity-gain follower and active filter configurations up to ~100 kHz.
It features low-frequency noise of 15 µVpp (0.1–10 Hz), 55 nV/√Hz input voltage noise at 1 kHz, and THD+N of 0.0005% at 1 kHz with 5 Vpp output - all specified across full 3–16 V supply and –40 °C to 125 °C operating range, meeting AEC-Q100 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - supports direct interface with 3.3 V, 5 V, and 12 V automotive/industrial rails without level-shifting. |
| Gain Bandwidth Product | 900 kHz typ. at 16 V - enables stable closed-loop gain ≥10 up to ~90 kHz with adequate phase margin (>55°). |
| Input Offset Voltage (A-grade) | 600 µV max at 25 °C; 1.8 mV max over –40 °C to 125 °C - ensures <0.1% error in 2 V full-scale sensor outputs without trimming. |
| Supply Current per Channel | 235 µA typ. at 5 V - allows dual op-amp operation on microamp-level power budgets (e.g., 470 µA total for both channels). |
| Input Bias Current | 1 pA typ. at 25 °C - preserves signal integrity when driving from >1 GΩ sources (e.g., piezoelectric sensors, pH electrodes). |
| Common-Mode Rejection Ratio | 95 dB typ. at 16 V - rejects supply ripple and ground noise in single-supply sensor front-ends with high accuracy. |
| ESD Tolerance (HBM) | 4 kV - withstands handling and board-level ESD events without latch-up or parametric shift in automotive assembly lines. |
Pinout & Package
TSX562AIYST is packaged in a wettable flank DFN8 2 mm × 2 mm (0.55 mm height) with exposed thermal pad, optimized for automated optical inspection (AOI) and thermal dissipation (RthJA = 120 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential feedback; compatible with resistor networks up to 10 MΩ without significant bias current error. |
| 2 | Non-inverting Input (Channel A) | Rail-to-rail input stage enables sensing from ground to VCC; maintains low Vos drift when biased near supply rails. |
| 3 | VCC– (GND) | Power return reference for both channels; must be low-inductance connection to minimize PSRR degradation and oscillation risk. |
| 4 | Output (Channel A) | Capable of sourcing/sinking 30 mA (typ.) at 16 V - drives 10 kΩ loads directly or interfaces with ADC input buffers without external gain stage. |
| 5 | VCC+ | Positive supply rail; requires local 10 nF ceramic decoupling within 2 mm to suppress high-frequency supply noise coupling into inputs. |
| 6 | Inverting Input (Channel B) | Independent second channel input; electrically isolated from Channel A - enables dual-sensor conditioning or differential-to-single-ended conversion. |
| 7 | Non-inverting Input (Channel B) | Matches Channel A specs; supports identical biasing schemes - simplifies layout symmetry and matching in precision instrumentation. |
| 8 | Output (Channel B) | Full rail-to-rail swing (VOL = 70 mV, VOH = VCC – 70 mV) - delivers clean logic-compatible levels for microcontroller analog inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with extended common-mode range | Operates from –0.1 V to VCC + 0.1 V, enabling direct interfacing with sensors whose output spans near ground or near VCC. |
| A-grade input offset voltage | 600 µV max at 25 °C and 1.8 mV max over full temperature range - eliminates need for system-level calibration in cost-sensitive automotive modules. |
| Ultra-low input bias current | 1 pA typical - prevents loading errors in high-Z source applications like photodiode transimpedance amplifiers or capacitive touch sense circuits. |
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to 125 °C) and 4 kV HBM ESD - certified for under-hood and body-control module deployment without derating. |
| Wide supply range with stable AC performance | GBP varies only ±10% from 3 V to 16 V - permits single BOM across multiple platform voltages (e.g., 3.3 V infotainment and 12 V powertrain subsystems). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSX562IST | Standard grade (1 mV max Vos at 25 °C); otherwise identical electrical specs and package. | Suitable for non-critical industrial signal chains where system calibration compensates for initial offset. | Select when cost sensitivity outweighs need for guaranteed low-offset performance across temperature. |
| MCP6022-E/SN | Lower GBP (1 MHz), higher supply current (1 mA), no AEC-Q100 qualification; SOIC-8 package only. | Limited to commercial-temperature (<85 °C), non-automotive designs requiring faster response but tolerant of higher power. | Choose only for prototyping or non-automotive applications where DFN8 footprint and automotive compliance are not required. |
Compared with TSX562IST, the TSX562AIYST provides tighter offset control critical for uncalibrated automotive sensors; versus MCP6022-E/SN, it delivers 4× lower quiescent current and guaranteed automotive reliability in a 40% smaller footprint - making it optimal for production-grade, space- and power-constrained modules.

FAQ
What is the maximum capacitive load the TSX562AIYST can drive without instability?
The TSX562AIYST maintains ≥55° phase margin with up to 100 pF capacitive load at 12 V supply, as verified in Figure 13 of the datasheet. For loads >100 pF, a series isolation resistor (≥100 Ω) between output and capacitance is required to preserve stability - especially critical in ADC driver or filter applications where parasitic capacitance exceeds 50 pF.
Does the TSX562AIYST support true rail-to-rail output swing?
No - the TSX562AIYST features rail-to-rail *input* only. Its output swings to within 70 mV of each rail (VOL = 70 mV, VOH = VCC – 70 mV) under 10 kΩ load, as specified in Tables 4–6. This limited output swing is sufficient for driving SAR ADC references or microcontroller GPIOs but not for driving logic thresholds requiring full rail compliance.
How does the long-term input offset voltage drift affect system calibration intervals?
TSX562AIYST exhibits 1.6 nV/√month typical long-term Vos drift at 25 °C (Table 6 note). Over 10 years (120 months), this accumulates to ~17.5 µV - negligible versus its 600 µV max spec. Thus, systems using this device require no periodic recalibration, unlike op-amps with >100 nV/√month drift that demand annual field service.
Can the TSX562AIYST operate reliably from a single 3.3 V supply with rail-to-rail input signals?
Yes - the device is fully characterized at 3.3 V (Table 4), delivering 900 kHz GBP, 1.1 V/µs slew rate, and 600 µV max Vos. Its rail-to-rail input accepts signals from –0.1 V to 3.4 V, enabling direct interface with 3.3 V-output sensors (e.g., MEMS accelerometers) without level-shifting, while maintaining 84 dB CMRR and 55 nV/√Hz noise performance.
