Product details
Overview
TSL6202IYST from STMicroelectronics is a dual-channel, automotive-grade rail-to-rail input/output operational amplifier with 8 MHz gain-bandwidth product, unity-gain stability, and operation across 2.5 V to 5.5 V supply. It delivers ±4.5 mV input offset voltage, 1 pA typical input bias current, and supports extended temperature range (–40 °C to +125 °C), making it suitable for battery-powered sensor signal conditioning in engine control units.
For engineers reviewing the TSL6202IYST datasheet, TSL6202IYST pinout, TSL6202IYST application, or TSL6202IYST equivalent, this device is selected for cost-sensitive, high-reliability analog front-ends where rail-to-rail swing, low quiescent current (750–1400 µA per channel), and AEC-Q100 qualification are mandatory.
Technical Context
The TSL6202IYST integrates two independent, unity-gain-stable amplifiers in a single MiniSO8 package, each featuring a rail-to-rail input stage using complementary input pairs and a rail-to-rail output stage with Class AB push-pull topology. Its 8 MHz GBP enables stable closed-loop operation down to gain = 1 without external compensation.
Designed for automotive environments, it meets AEC-Q100 Grade 0 requirements, with common-mode input range extending 0.1 V beyond rails (VCC− – 0.1 V to VCC+ + 0.1 V) and output swing within 40 mV of each rail under 10 kΩ load. Phase margin is guaranteed at ≥45° with 2 kΩ load and 100 pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - Enables stable unity-gain buffer and 2nd-order filter designs up to ~1.3 MHz. |
| Input Offset Voltage | ±4.5 mV (25 °C), ±7.5 mV (–40 °C to +125 °C) - Limits DC error in precision sensor interfaces. |
| Supply Voltage Range | 2.5 V to 5.5 V - Supports direct connection to 3.3 V and 5 V automotive domains without LDO. |
| Input Bias Current | 1 pA typ. - Minimizes voltage error across high-impedance source networks (e.g., thermistor dividers). |
| Slew Rate | 4.5 V/µs - Supports 10-bit settling in <1 µs for moderate-speed data acquisition paths. |
| Quiescent Current | 750–1400 µA per channel - Enables dual-opamp integration in ultra-low-power wake-up circuits. |

Pinout & Package
Supplied in MiniSO8 (8-pin SOIC narrow) package, measuring 2.8 mm × 3.0 mm × 1.05 mm (max height), with 0.65 mm lead pitch and ECOPACK® RoHS-compliant finish.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output node of Channel 1 - Sinks/sourcing capability up to ±30 mA; rail-to-rail swing ensures full dynamic range utilization. |
| 2 | IN1− | Inverting input of Channel 1 - High-impedance node (1 pA bias) compatible with passive RC filters and feedback networks. |
| 3 | IN1+ | Non-inverting input of Channel 1 - Rail-to-rail common-mode range allows direct interfacing with resistive sensors referenced to VCC− or VCC+. |
| 4 | VCC− | Negative supply rail - Shared reference for both amplifiers; must be connected to system ground or negative rail. |
| 5 | IN2+ | Non-inverting input of Channel 2 - Independent of Channel 1; enables differential pair or dual-sensor readout without crosstalk. |
| 6 | IN2− | Inverting input of Channel 2 - Matches IN1− electrical characteristics; supports matched gain-setting resistor layouts. |
| 7 | OUT2 | Output node of Channel 2 - Electrically isolated from OUT1; supports independent load driving (e.g., dual ADC drivers). |
| 8 | VCC+ | Positive supply rail - Supplies both channels; decoupling capacitor (100 nF) recommended within 5 mm of Pin 8. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Lower GBP (8 MHz same), higher Vio (±1.5 mV typ.), wider VCC (2.7–5.5 V), no AEC-Q100 grade | Targeted at industrial/commercial systems only; lacks automotive qualification and extended temp support | Select when AEC-Q100 is not required and lower offset is prioritized over temperature range. |
| LMV358QDRQ1 | Lower GBP (1 MHz), higher Iib (10 nA), same AEC-Q100 Grade 1, wider temp (–40 °C to +125 °C) | Optimized for ultra-low-cost, low-bandwidth monitoring; unsuitable for >100 kHz signal paths | Select only for non-critical voltage followers or slow-moving sensor outputs where bandwidth is secondary. |
Compared with TSV912IDT and LMV358QDRQ1, the TSL6202IYST uniquely balances AEC-Q100 Grade 0 qualification, 8 MHz bandwidth, and 1 pA bias current-making it the only option among the three qualified for high-accuracy, high-speed analog sensing in under-hood automotive modules.

FAQ
Is TSL6202IYST pin-compatible with other dual op amps in MiniSO8?
No-TSL6202IYST uses a non-standard MiniSO8 pinout: VCC− is on Pin 4 (not Pin 3 or Pin 8), and the input/output arrangement differs from industry conventions like LM358 or TLV2372. Layout redesign is required for substitution; refer to Table 2 in DS13727 for exact terminal mapping.
Does TSL6202IYST support single-supply operation with ground-referenced inputs?
Yes-its rail-to-rail input stage accepts common-mode voltages from VCC− – 0.1 V to VCC+ + 0.1 V. When VCC− = GND, inputs operate from –0.1 V to VCC+ + 0.1 V, enabling direct interface with ground-referenced sensors and microcontroller ADC references without level-shifting circuitry.
What is the maximum capacitive load the TSL6202IYST can drive while maintaining stability?
The device is characterized for stability with up to 100 pF capacitive load in unity-gain configuration (DS13727, Figure 11). Driving >100 pF requires isolation resistor (≥100 Ω) between output and load capacitance to preserve phase margin ≥45°, as confirmed by AC simulation and bench testing in the datasheet.
How does the automotive grade (IYST suffix) differ electrically from the industrial version (IST suffix)?
Both share identical electrical specs, but TSL6202IYST undergoes additional AEC-Q100 stress tests (HTOL, TC, UHAST), advanced screening per AEC-Q001/Q002, and lot-level traceability. No parameter binning or derating is applied-the "IYST" grade guarantees conformance across full automotive temperature and lifetime requirements.
