Product details

Overview

TS9511IYLT from STMicroelectronics is a single precision rail-to-rail input/output operational amplifier optimized for automotive-grade applications. It delivers 800 µV max input offset voltage, 3 MHz gain-bandwidth product, 1 V/µs slew rate, and operates from 2.7 V to 12 V supply. Its SOT23-5 package supports space-constrained signal conditioning in automotive infotainment and sensor interface circuits.

For engineers reviewing the TS9511IYLT datasheet, TS9511IYLT pinout, TS9511IYLT application, or TS9511IYLT equivalent, key selection criteria include rail-to-rail I/O swing at low supply (2.7 V), AEC-Q100 qualification, 125 °C operating temperature, and precision performance under varying load and thermal conditions.

Technical Context

The TS9511IYLT implements a precision bipolar-input op-amp architecture with rail-to-rail input common-mode range (V_DD − 0.2 V to V_CC + 0.2 V) and rail-to-rail output swing (within 80 mV of rails at 600 Ω load). Its 3 MHz GBP and 1 V/µs slew rate support stable unity-gain buffer and low-distortion line driver operation.

It achieves 85 dB supply voltage rejection ratio and 90 dB common-mode rejection at DC, enabling robust performance in noisy automotive power domains. The device maintains 800 µV max V_IO across −40 °C to +125 °C, with 2 µV/°C drift, meeting precision analog requirements without external trimming.

Equivalent & Alternatives

The following parts are listed as comparable options for similar precision rail-to-rail op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS9512IYLT	Dual-channel version in same SOT23-5L package; identical specs per channel	Reduces board area in multi-signal conditioning designs (e.g., stereo audio, dual sensor inputs)	Select when two matched amplifiers are required and PCB real estate is constrained
MCP6001T-I/OT	Lower GBP (1 MHz), higher V_IO (1.5 mV max), no AEC-Q100 qualification	Targeted at cost-sensitive consumer electronics, not automotive environments	Choose only for non-automotive applications where temperature range and precision are less demanding

Compared with TS9512IYLT, the TS9511IYLT saves board space in single-channel systems and avoids inter-channel crosstalk; versus MCP6001T-I/OT, it provides superior offset accuracy, wider temperature range, and automotive qualification-critical for safety-relevant signal chains.

FAQ

What is the maximum allowable supply voltage for TS9511IYLT?

The absolute maximum supply voltage is 14 V, but the recommended operating range is 2.7 V to 12 V. Operation above 12 V risks exceeding internal junction temperature limits and degrading long-term reliability, especially at elevated ambient temperatures. The device is characterized and guaranteed only within the 2.7–12 V range.

Does TS9511IYLT require external compensation for unity-gain stability?

No external compensation is required. The TS9511IYLT is internally compensated for unity-gain stability, with a phase margin of 58° at 3 MHz (RL = 10 kΩ, CL = 100 pF). It remains stable driving capacitive loads up to 100 pF directly, making it suitable for DAC output buffering without added isolation resistors.

How does the AEC-Q100 qualification of TS9511IYLT differ from standard industrial grade?

TS9511IYLT is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C), including stress tests for temperature cycling, high-temperature operating life (HTOL), and ESD (HBM 1 kV, CDM 1.5 kV). Standard industrial parts typically meet only JEDEC JESD22-A104 and lack automotive-specific failure analysis and screening protocols.

Can TS9511IYLT drive a 600 Ω load to full rail-to-rail swing at 125 °C?

Yes-it delivers VOH ≥ 2.8 V and VOL ≤ 250 mV into 600 Ω at VCC = 3 V and T_A = 125 °C, confirming rail-to-rail capability across the full automotive temperature range. Output swing degradation is limited to <100 mV at both rails under worst-case conditions, preserving dynamic range in high-temperature environments.
