Product details
Overview
TLV2461IDR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2461IDR datasheet, TLV2461IDR pinout, TLV2461IDR application, or TLV2461IDR equivalent, key selection criteria include its −40°C to 125°C automotive-grade temperature range, micropower shutdown mode (0.3 µA/channel), rail-to-rail swing at 2.7–6 V supply, and compatibility with space-constrained SOT-23-8 layouts.
Technical Context
The TLV2461IDR employs a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing within 100 mV of each rail under load. Its internal architecture supports stable unity-gain operation with up to 160 pF capacitive load while maintaining ≥44° phase margin.
It integrates a dedicated SHDN pin that places the amplifier into ultralow-current shutdown (0.3 µA/channel) and forces output into high-impedance state - critical for power-gated signal chains in battery-powered instrumentation and automotive body control modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Same architecture and pinout; rated for 0°C to 70°C only; higher max VIO (2000 µV vs 1500 µV). | Restricted to commercial-grade applications (e.g., consumer electronics, non-automotive industrial). | Select when cost sensitivity outweighs extended temperature or automotive qualification requirements. |
| OPA333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2461IDR's 2 µV/°C; higher supply current (17 µA vs 500 µA); no shutdown pin. | Better DC precision but unsuitable for ultra-low-power or shutdown-dependent systems. | Choose for high-accuracy DC-coupled measurement where offset drift dominates error budget and power is not constrained. |
Compared with TLV2461CDR, TLV2461IDR provides guaranteed performance across automotive temperatures and tighter offset specs; compared with OPA333AIDR, it trades zero-drift precision for 35× lower quiescent current and integrated shutdown - making it optimal for battery-operated, wide-temperature sensing nodes.

FAQ
What is the maximum supply voltage for TLV2461IDR?
The absolute maximum supply voltage for TLV2461IDR is 6 V. Operation beyond this rating risks permanent damage. The recommended operating range is 2.7 V to 6 V for single-supply use, or ±1.35 V to ±3 V for split-supply configurations. At 6 V, output swing remains rail-to-rail with <100 mV saturation, and all electrical specifications remain valid across the full −40°C to 125°C temperature range.
Does TLV2461IDR support true rail-to-rail input and output?
Yes, TLV2461IDR supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at ±10 mA load). This is achieved via complementary CMOS input pairs and push-pull output stage. Unlike earlier rail-to-rail op-amps, TLV2461IDR maintains high output drive and low distortion across the entire range - verified in TI's SLOS220J datasheet Figures 5–8 and Table 7.
How does the shutdown feature of TLV2461IDR operate?
The SHDN pin (Pin 6) on TLV2461IDR is active-low: driving it below 0.7 V places the amplifier in shutdown mode, reducing supply current to 0.3 µA/channel and forcing the output into high-impedance state. Pulling SHDN above 2 V returns the device to normal operation with 500 µA/channel IDD. This behavior is fully characterized across −40°C to 125°C and supports direct interfacing with 1.8 V or 3.3 V microcontroller GPIOs.
What is the typical input offset voltage of TLV2461IDR and how does it vary with temperature?
The typical input offset voltage of TLV2461IDR is 100 µV at 25°C, with a maximum of 1500 µV across the full −40°C to 125°C range. Its temperature coefficient is 2 µV/°C (typ), meaning offset drift contributes ≤300 µV over a 150°C span. This is specified in the "Electrical Characteristics" table (page 7) of the SLOS220J datasheet and confirmed in Figure 1–2 showing VIO vs VICR across temperatures.
Is TLV2461IDR qualified for automotive applications?
Yes, TLV2461IDR carries the "I" temperature suffix (−40°C to +125°C) and is explicitly qualified for automotive applications per TI's documentation. It appears in the "Q-Temp Automotive" and "HighRel Automotive Applications" sections of the datasheet, and supports configuration control, print support, and qualification to automotive standards - making it suitable for body electronics, infotainment interfaces, and ADAS subsystems.
