Product details
Overview
TLV2464IPWR 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.
For engineers reviewing the TLV2464IPWR datasheet, TLV2464IPWR pinout, TLV2464IPWR application, or TLV2464IPWR equivalent, key selection criteria include its −40°C to 125°C automotive-grade temperature range, TSSOP-14 package with integrated shutdown control per channel, rail-to-rail swing at 2.7–6 V supply, and verified performance in precision analog signal conditioning circuits.
Technical Context
The TLV2464IPWR implements a CMOS input stage with rail-to-rail input common-mode range extending beyond both supply rails (0 V to VDD), paired with a robust push-pull output stage capable of sourcing/sinking ±80 mA while maintaining rail-to-rail swing. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate are achieved with only 500 µA per channel, balancing ac fidelity and micropower operation.
Each of the four amplifiers features an independent shutdown terminal (pins 1/2SHDN and 3/4SHDN), reducing supply current to 0.3 µA/channel when asserted. In shutdown, outputs enter high-impedance state - critical for power-gated multi-channel signal paths in battery-powered instrumentation and automotive ECUs.
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 without slewing distortion. |
| Supply Current per Channel | 500 µA - allows four-channel operation at <2 mA total, suitable for always-on sensor signal chains. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in 2.5 V full-scale 16-bit ADC reference buffers. |
| Rail-to-Rail Output Swing | Within 10 mV of rails at 10 mA load - maximizes dynamic range in single-supply 3.3 V systems. |
| Shutdown Current per Channel | 0.3 µA - reduces quiescent power to <1.2 µA for all four channels during system sleep modes. |
| Operating Temperature Range | −40°C to 125°C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm × 1.2 mm height) with exposed thermal pad; RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | 1OUT, 1IN− | Channel 1 output and inverting input - direct connection to feedback network for inverting configurations. |
| 3, 4 | 1IN+, GND | Channel 1 non-inverting input and system ground reference - GND pin must be low-impedance for noise immunity. |
| 5, 6 | VDD+, 2IN+ | Positive supply and Channel 2 non-inverting input - decoupling capacitor required at VDD+ near pin 5. |
| 7, 8 | 2IN−, 2OUT | Channel 2 inverting input and output - forms standard op-amp pair with pins 5–8 for dual-channel layout. |
| 9, 10 | 3OUT, 3IN− | Channel 3 output and inverting input - identical functional role to pins 1/2 for third amplifier. |
| 11, 12 | 3IN+, GND | Channel 3 non-inverting input and second ground pin - improves grounding for multi-channel isolation. |
| 13, 14 | 4IN−, 4IN+ | Channel 4 inverting and non-inverting inputs - pin 14 is isolated from internal ESD protection diodes for high-Z sensor inputs. |
| 1/2SHDN, 3/4SHDN | Shutdown control | Pins 1 and 14 serve as shared shutdown enables: pin 1 controls channels 1 & 2; pin 14 controls channels 3 & 4. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–VDD signal swing in single-supply systems without level-shifting circuitry. |

| ±80 mA output drive capability | Drives 37.5 Ω loads directly (e.g., 75 Ω coax with 2× termination), eliminating external buffers in data acquisition. |
| 11 nV/√Hz input voltage noise | Preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges) without added noise penalty. |
| Automotive Q-temp qualification | Meets AEC-Q100 Grade 1 requirements for reliability in engine control, ADAS, and body electronics. |

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; SOIC-14 package (8.65 mm × 3.9 mm), no thermal pad, higher θJA (122.6°C/W). | Preferred for through-hole prototyping or legacy PCBs requiring SOIC footprint; less suitable for high-density thermal-constrained layouts. | Select TLV2464IDR when board space permits larger package and thermal dissipation is managed via copper area. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower offset (2 µV max), but higher supply current (17 µA/ch) and no shutdown function. | Better for ultra-precision DC-coupled applications (e.g., weigh scales); unsuitable where micropower shutdown or 125°C operation is required. | Choose OPA2333PWR only when sub-µV offset stability outweighs power budget and temperature range constraints. |
Compared with TLV2464IPWR, TLV2464IDR offers identical functionality in a larger SOIC package with inferior thermal performance, while OPA2333PWR trades micropower and shutdown capability for nanovolt-level offset stability - making TLV2464IPWR the optimal balance for automotive and industrial multi-channel signal conditioning.

FAQ
What is the maximum supply voltage for TLV2464IPWR?
The absolute maximum supply voltage for TLV2464IPWR is 6 V. Operation beyond this limit 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/output performance and specified electrical characteristics.
Does TLV2464IPWR support true rail-to-rail input and output?
Yes, TLV2464IPWR supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing within 10 mV of each rail at 10 mA 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 single-supply systems.
How does the shutdown feature work on TLV2464IPWR?
TLV2464IPWR has two independent shutdown controls: pin 1 (1/2SHDN) disables channels 1 and 2, while pin 14 (3/4SHDN) disables channels 3 and 4. When a shutdown pin is pulled below 0.7 V (VIL), that pair enters ultralow-current mode (0.3 µA/channel), and its output transitions to high-impedance state - verified in the "Electrical Characteristics" table under IDD(SHDN).
What is the thermal performance of TLV2464IPWR in TSSOP-14 package?
TLV2464IPWR in TSSOP-14 (PW package) has θJA = 173.6°C/W and θJC = 29.3°C/W. At TA < 125°C, its power rating is 144 mW (derated from 720 mW at TA ≤ 25°C). The exposed thermal pad must be soldered to PCB copper for effective heat dissipation - critical for sustained ±80 mA output operation at elevated ambient temperatures.
Is TLV2464IPWR qualified for automotive applications?
Yes, TLV2464IPWR carries the "I" temperature suffix (−40°C to 125°C) and is explicitly listed in TI's Q-Temp Automotive documentation. It meets AEC-Q100 stress test requirements for automotive grade 1 applications, including engine control units, ADAS sensor interfaces, and body electronics where extended temperature operation and long-term reliability are mandatory.
