Product details
Overview
TLV2464AIN from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-power portable and industrial signal conditioning. 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 buffering of ADC inputs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464AIN datasheet, TLV2464AIN pinout, TLV2464AIN application, or TLV2464AIN equivalent, this device is selected for precision analog signal chains requiring rail-to-rail swing, wide temperature operation (−40°C to 125°C), and shutdown capability across all four channels in a single 14-pin TSSOP package.
Technical Context
The TLV2464AIN 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 from 2.7 V to 6 V. Its architecture enables direct interfacing with SAR and delta-sigma ADCs without level-shifting.
Each channel features an active-low shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state. The device maintains stable unity-gain performance with capacitive loads up to 160 pF and exhibits 45° phase margin at 5 V supply.
Key Specifications

|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~1 MHz with moderate gain (e.g., AV = 5) in sensor signal conditioning. |
| Slew Rate | 1.6 V/µs - enables accurate reproduction of 100 kHz full-scale sine waves at 2 VPP without distortion. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.002% error in 5 V full-scale 16-bit ADC buffer applications. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, critical for always-on battery-powered nodes. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails at 10 mA load - maximizes dynamic range in 3.3 V systems. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power by >99.9% during system sleep modes. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive and industrial control environments. |

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 and pinout; rated for −40°C to 125°C but in tape-and-reel 14-pin SOIC (D) package. | Larger footprint and higher thermal resistance (θJA = 122.6°C/W vs. 173.6°C/W for PW); less suitable for space-constrained PCBs. | Choose when legacy SOIC layout compatibility or higher moisture sensitivity tolerance is required. |
| OPA4340UA | Higher GBW (5.5 MHz vs. 6.4 MHz), lower noise (8 nV/√Hz), but no shutdown function and higher supply current (750 µA/ch). | Not suitable for power-gated systems; requires additional external enable logic for low-power sequencing. | Prefer when ultra-low noise dominates over shutdown capability and board area constraints. |
Compared with TLV2464AIN, TLV2464IDR offers identical functionality in a larger SOIC package better suited for manual assembly or high-reliability industrial boards, while OPA4340UA trades off shutdown and power efficiency for superior noise performance in continuous-operation instrumentation.

FAQ
What is the maximum supply voltage for TLV2464AIN?
The absolute maximum supply voltage for TLV2464AIN is 6 V. Operation above this level risks permanent damage. Recommended operating range is 2.7 V to 6 V for optimal rail-to-rail performance and stability. At 6 V, output swing remains within 100 mV of both rails under 10 mA load, preserving dynamic range in high-voltage sensor interfaces.
Does TLV2464AIN support true rail-to-rail input and output?
Yes, TLV2464AIN supports true rail-to-rail input (common-mode range extends from GND to VDD) and rail-to-rail output (swing within 100 mV of both rails at 10 mA load). This enables direct interfacing with 3.3 V ADCs without external level-shifting, maximizing usable input range and reducing component count in precision analog front-ends.
How does the shutdown feature work on TLV2464AIN?
TLV2464AIN has four independent active-low shutdown inputs (pins 1/2/3/4 of the 1/2/3/4SHDN group per channel). Driving any SHDN pin below 0.7 V places its corresponding amplifier into ultralow-current mode (0.3 µA/channel) and forces the output into high-impedance state. All four channels can be controlled individually or tied together for system-wide power gating.
What is the thermal performance of TLV2464AIN in its TSSOP package?
In the 14-pin TSSOP (PW) package, TLV2464AIN has θJA = 173.6°C/W and θJC = 29.3°C/W. At 25°C ambient and full 2 mA supply current, junction temperature rise is ~58°C - well within the 150°C maximum. For continuous 125°C ambient operation, derating to ≤144 mW total power (≤36 mW per channel) is required to maintain safe junction temperature.
Is TLV2464AIN qualified for automotive applications?
Yes, TLV2464AIN carries the 'I' temperature suffix (−40°C to 125°C) and is explicitly qualified for automotive applications per TI's Q-Temp program. It meets AEC-Q100 stress testing requirements and is listed in TI's high-reliability automotive portfolio for use in cabin electronics, body control modules, and powertrain subsystems where extended temperature operation is mandatory.
