STMicroelectronics TSB611IYLT

Overview

TSB611IYLT from STMicroelectronics is a single-channel, rail-to-rail output, low-power operational amplifier designed for precision signal conditioning in high-voltage industrial and automotive systems. It delivers 1 mV max input offset voltage, 560 kHz gain bandwidth product at 36 V, 125 μA max supply current per channel, -40 °C to 125 °C operating range, and rail-to-rail output swing within 100 mV of rails - enabling accurate sensing in battery monitoring and 24 V power supply feedback loops.

For engineers reviewing the TSB611IYLT datasheet, TSB611IYLT pinout, TSB611IYLT application, or TSB611IYLT equivalent, key selection considerations include its extended 2.7–36 V supply range, input common-mode voltage including ground, 4 kV HBM ESD rating, unity-gain stability with capacitive loads up to 500 pF, and guaranteed performance across automotive temperature extremes.

Technical Context

The TSB611IYLT employs a proprietary bipolar-input architecture optimized for low offset drift (≤6 μV/°C) and high CMRR (up to 130 dB) over full temperature and supply range. Its rail-to-rail output stage uses complementary push-pull transistors capable of sourcing/sinking ≥40 mA at 36 V while maintaining <150 mV saturation voltage.

Input stage design incorporates ESD protection diodes rated to 4 kV HBM and supports common-mode voltages from VCC− −0.1 V to VCC+ −1 V - enabling direct interfacing with grounded sensors and single-supply ADC drivers without level-shifting circuitry.

FAQ

What is the maximum capacitive load the TSB611IYLT can drive while remaining stable?

The TSB611IYLT is unity-gain stable and maintains ≥60° phase margin with up to 500 pF capacitive load when driving a 10 kΩ resistive load, as verified in DS11136 Figure 27. For loads exceeding 100 pF, ST recommends adding a series isolation resistor (R_iso) between the output and capacitance - values range from 10 Ω (100 pF) to 1 kΩ (10 nF) per Figure 35.

Does the TSB611IYLT require external compensation for operation at 36 V supply?

No external compensation is required. The device is internally compensated for unity-gain stability across its full 2.7–36 V supply range and -40 °C to 125 °C temperature range, as confirmed by phase margin ≥58° in Table 3 and Figure 25 at 36 V.

Can the TSB611IYLT be used with input signals that exceed the supply rails?

Input voltages must remain within (VCC− −0.2 V) to (VCC+ +0.2 V) per absolute maximum ratings. Exceeding these violates ESD diode limits - input current must be externally limited to ≤10 mA using series resistors or Schottky clamps, as detailed in Section 4.6 of DS11136.

Is the TSB611IYLT AEC-Q100 qualified?

Yes - the TSB611IYLT is qualified to AEC-Q100 Grade 1 (-40 °C to 125 °C) and manufactured in ST's IATF 16949-certified facilities, with full qualification test reports available upon request for automotive program validation.
