Product details
Overview
TLV2464IN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage portable and industrial systems. It delivers 6.4 MHz gain-bandwidth, 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 at 2.7–6 V operation.
For engineers reviewing the TLV2464IN datasheet, TLV2464IN pinout, TLV2464IN application, or TLV2464IN equivalent, this device is selected for precision analog signal conditioning where rail-to-rail swing, micropower shutdown (0.3 µA/channel), and extended temperature range (−40°C to 125°C) are critical design requirements.
Technical Context
The TLV2464IN integrates four independent amplifiers with fully rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, supporting single-supply operation down to 2.7 V. Its architecture enables high-output-drive capability without sacrificing DC precision or noise performance.
Each channel features an active shutdown terminal (SHDN) that places the amplifier into ultralow-current mode (0.3 µA/channel) while forcing the output into high-impedance state - essential for power-gated signal chains in battery-powered instrumentation and automotive control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - enables clean 10-bit+ signal reproduction for 100 kHz full-scale sine waves at 3–5 V supplies. |
| Supply Current / Channel | 500 µA - allows four-channel operation under 2 mA total, suitable for always-on sensor monitoring circuits. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5 V full-scale 12-bit systems without trimming. |
| Output Drive | ±80 mA - drives 60 Ω loads directly (e.g., coaxial cable termination) without external buffers. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - maximizes dynamic range in 3.3 V and lower systems. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power by >99.9% per channel during idle periods. |
Pinout & Package
TLV2464IN is housed in a 14-pin plastic DIP (N) package with through-hole mounting and 0.3-inch body width. Pin 1 is identified by a molded dot or beveled edge.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Same electrical specs; SOIC-14 package (surface-mount) instead of PDIP-14; tape-and-reel packaging. | Preferred for automated SMT assembly; requires PCB redesign vs. through-hole TLV2464IN. | Select TLV2464IDR for volume production with pick-and-place; retain TLV2464IN for prototyping or legacy through-hole designs. |
| OPA4340UA | Higher precision (50 µV VIO), lower noise (8 nV/√Hz), but higher supply current (750 µA/channel); no shutdown function. | Better suited for ultra-low-error metrology; lacks per-channel shutdown needed for dynamic power management. | Choose OPA4340UA when offset and noise dominate over power; choose TLV2464IN when shutdown capability and 500 µA/channel are mandatory. |
Compared with TLV2464IDR, TLV2464IN offers identical analog performance in a through-hole package for manual assembly and legacy compatibility; compared with OPA4340UA, TLV2464IN trades 50 µV offset and 3 nV/√Hz noise for 250 µA/channel lower quiescent current and integrated shutdown - making it optimal for power-constrained, multi-channel signal chains requiring selective channel disable.

FAQ
What is the maximum supply voltage for TLV2464IN?
The absolute maximum supply voltage for TLV2464IN is 6 V. Operation beyond this 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 - ensuring rail-to-rail input and output functionality remains intact across the full range.
Does TLV2464IN support true rail-to-rail input and output?
Yes, TLV2464IN supports true rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swing within 100 mV of both rails under load). This is confirmed in the datasheet's "Recommended Operating Conditions" and "Electrical Characteristics" tables for both 3 V and 5 V supplies, enabling full dynamic range utilization in low-voltage systems.
How does the shutdown feature work on TLV2464IN?
TLV2464IN provides individual shutdown control for Amplifier A (Pin 6) and Amplifier B (Pin 13). Applying <0.7 V to either SHDN pin disables its respective amplifier, reducing supply current to 0.3 µA/channel and placing the output in high-impedance state. Pins 1SHDN and 2SHDN are not connected to Amplifiers C and D - only A and B have dedicated shutdown terminals.
What is the input offset voltage specification for TLV2464IN?
The input offset voltage for TLV2464IN is specified as 100 µV (typical) and 1500 µV (maximum) over the full −40°C to 125°C temperature range. At 25°C, the maximum is 500 µV. These values are measured per channel under standard test conditions (VDD = 3 V or 5 V, VIC = VDD/2, VO = VDD/2) and apply to all four amplifiers in the package.
Is TLV2464IN qualified for automotive applications?
Yes, TLV2464IN carries the "I" temperature suffix, meaning it is rated for −40°C to 125°C operation and qualified to automotive standards per TI's Q-Temp program. It is explicitly listed in the datasheet as suitable for "HighRel Automotive Applications" and "Configuration Control/Print Support", confirming its suitability for under-hood and chassis-mounted automotive subsystems.
