Product details
Overview
TSB622IYQ3T from STMicroelectronics is a dual-channel, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100), featuring 1.7 MHz gain bandwidth product, 1 mV max input offset voltage at 25 °C, and operation across 2.7–36 V supply range. It delivers 375 µA max supply current per channel at 36 V and supports industrial power supplies and battery management circuits requiring high ESD tolerance (4 kV HBM) and extended temperature operation (−40 to 125 °C).
For engineers reviewing the TSB622IYQ3T datasheet, TSB622IYQ3T pinout, TSB622IYQ3T application, or TSB622IYQ3T equivalent, key selection criteria include its dual-channel configuration in DFN8 (3 × 3 mm) wettable flanks package, rail-to-rail output swing, −40 to 125 °C operating range, and suitability for precision sensing in automotive body control modules and industrial DC-DC feedback loops.
Technical Context
The TSB622IYQ3T implements a bipolar-input op-amp architecture optimized for wide-supply operation and low quiescent current. Its input common-mode range includes ground, enabling single-supply sensor interfacing, while rail-to-rail output ensures full dynamic range utilization across 2.7–36 V.
It achieves unity-gain stability with 45° phase margin and 18 dB gain margin under 100 pF capacitive load, supporting robust closed-loop performance in voltage monitoring and current-sense amplification without external compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSB622IST | Same die, MiniSO8 package (2.8 × 4.9 mm) - larger footprint, no wettable flanks. | Preferred for manual rework or legacy PCBs with SO8 footprints; lower thermal resistance (190 °C/W vs. 40 °C/W). | Select when AOI capability is not required and board area permits larger package. |
| TSB622IDT | Same die, SO8 package (4.9 × 6.0 mm) - standard industry footprint, higher RthJA (125 °C/W). | Suitable for prototyping and non-automotive industrial use where AEC-Q100 is not mandated. | Choose for compatibility with existing SO8 tooling and test fixtures where automotive qualification is optional. |
Compared with TSB622IST and TSB622IDT, the TSB622IYQ3T offers superior manufacturability via wettable flanks for automated solder-joint inspection and lower thermal resistance (40 °C/W), making it optimal for high-volume automotive production where reliability and process control are critical.

FAQ
What is the maximum capacitive load the TSB622IYQ3T can drive while maintaining stability?
The TSB622IYQ3T maintains 45° phase margin and unity-gain stability with up to 100 pF capacitive load, as verified in DS13848 Figure 19–21. Driving >100 pF requires external isolation resistor (typically 10–100 Ω) between output and load to prevent peaking or oscillation.
Does the TSB622IYQ3T support true single-supply operation with input voltage down to ground?
Yes-the input common-mode voltage range extends to VCC− (ground in single-supply setups), per Table 5 (Vicm = (Vcc−) −0.1 V). This enables direct interfacing with grounded sensors, resistive bridges, or current-shunt elements without level-shifting circuitry.
How does the 375 µA max supply current per channel scale across temperature and supply voltage?
Supply current increases with temperature and supply voltage: at 12 V and 125 °C, ICC is ≤420 µA per channel (Table 7); at 36 V and 125 °C, it remains ≤420 µA (Table 8). The device exhibits monotonic but bounded increase, ensuring predictable power budgeting across full operating range.
Is the exposed pad on the DFN8 (A03Y) package electrically connected or thermal-only?
The exposed pad is thermally connected to the die substrate and may be left floating or soldered to a PCB ground plane for improved thermal dissipation. It is not electrically tied to any internal node-no voltage or signal connection is required or recommended.
