Product details

Overview

TS9511RIYLT from STMicroelectronics is a single-channel precision rail-to-rail input/output operational amplifier in SOT23-5 package, featuring 800 µV max input offset voltage, 3 MHz gain bandwidth, 1 V/µs slew rate, 2.7–12 V supply range, and automotive-grade qualification per AEC-Q100. It serves as a low-noise, low-power signal conditioner in portable audio and automotive sensor interfaces.

For engineers reviewing the TS9511RIYLT datasheet, TS9511RIYLT pinout, TS9511RIYLT application, or TS9511RIYLT equivalent, key selection criteria include rail-to-rail I/O swing at 3 V, ±1 mA input current limit under differential overvoltage, 125 °C operating temperature, and SOT23-5 thermal resistance (R_thJA = 250 °C/W).

Technical Context

The TS9511RIYLT implements a precision bipolar-input op-amp architecture optimized for wide-supply operation (2.7–12 V) and rail-to-rail output swing down to 80 mV from rails. Its 3 MHz GBP and 1 V/µs slew rate support unity-gain-stable buffer and line-driver configurations with <0.01% THD at 10 kHz.

Designed for automotive environments, it meets AEC-Q100 Grade 1 (−40 °C to +125 °C), includes 1 kV HBM ESD protection, and maintains 85 dB SVR across its full supply range-critical for noise-sensitive analog front-ends in battery-powered systems.

Key Specifications

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
LMV321QDBVRQ1	Higher 1.25 MHz GBP, lower 500 µV offset, but only 1.8–5.5 V supply range	Restricted to low-voltage automotive infotainment; cannot replace TS9511RIYLT in 12 V systems	Select when 5 V-only operation and tighter DC accuracy are prioritized over supply flexibility
MCP6001T-E/OT	Lower 1 µA supply current, but 1.8–6 V range and 1.5 mV offset (max)	Suitable for ultra-low-power battery sensors, not automotive-grade or high-precision signal chains	Choose for cost-sensitive consumer wearables where 125 °C operation and sub-mV offset are not required

Compared with LMV321QDBVRQ1 and MCP6001T-E/OT, the TS9511RIYLT uniquely combines AEC-Q100 qualification, 2.7–12 V operation, and 800 µV offset-making it the only option for precision analog stages in 12 V automotive modules requiring extended temperature stability.

FAQ

What is the maximum differential input voltage for TS9511RIYLT?

The absolute maximum differential input voltage is ±1 V. Exceeding this requires an external series resistor to limit input current to ≤±1 mA, as specified in Table 1 of the datasheet. This protects internal ESD structures and prevents phase reversal or latch-up in overvoltage conditions.

Does TS9511RIYLT support true single-supply operation?

Yes. With V− tied to ground and V+ supplied from 2.7–12 V, the device achieves rail-to-rail input (down to V− − 0.2 V) and output (within 80 mV of V− and V+). Its common-mode range extends 0.2 V beyond both rails, enabling direct interfacing with grounded sensors and 3.3 V ADCs.

How does the TS9511RIYLT's thermal performance compare in SOT23-5?

Its SOT23-5 package has R_thJA = 250 °C/W (typical) and R_thJC = 81 °C/W. At 1.2 mA supply current and 12 V supply, power dissipation remains below 15 mW-keeping junction temperature rise under 4 °C in still air, well within the −40 °C to +125 °C operating range.

Is TS9511RIYLT pin-compatible with TS9511ILT?

No. TS9511RIYLT uses a revised pinout introduced in Rev 5 (July 2013), where Pin 1 is OUT and Pin 5 is V+, whereas TS9511ILT uses Pin 1 as V+ and Pin 5 as OUT. PCB layout must be updated to avoid functional failure or damage during replacement.
