Product details
Overview
TLV2464AID 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 product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage across −40°C to 125°C. It serves as a precision buffer for ADC front-ends in battery-powered data acquisition systems.
For engineers reviewing the TLV2464AID datasheet, TLV2464AID pinout, TLV2464AID application, or TLV2464AID equivalent, this page provides verified electrical specifications, TSSOP-14 package details, shutdown functionality behavior, thermal derating guidance, and validated alternative options for automotive-grade analog signal chains.
Technical Context
The TLV2464AID integrates four independent rail-to-rail I/O op-amps with individual shutdown control per pair (pins 1/2SHDN and 3/4SHDN), enabling dynamic power management in multi-channel sensor interfaces. Its input common-mode range extends beyond rails (0 V to VDD), and output swings within 100 mV of each rail at ±10 mA load.
It operates from 2.7 V to 6 V single supply (or ±1.35 V to ±3 V dual supply), supports stable operation with capacitive loads up to 160 pF, and maintains ≥44° phase margin at unity gain with 10 kΩ//160 pF load. Shutdown mode reduces per-channel current to 0.3 µA while placing outputs in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~500 kHz with gain ≥12 in unity-gain-compensated configurations. |
| Slew Rate | 1.6 V/µs - Supports 12-bit settling of 2-Vpp signals in ≤1.8 µs with 0.01% accuracy under 56-pF load. |
| Input Offset Voltage | 1500 µV max (−40°C to 125°C) - Ensures <0.06% full-scale error in 2.5-V reference-buffering applications. |
| Supply Current / Channel | 550 µA typ at 5 V - Delivers 6.4-MHz bandwidth at <2.2 mW total quiescent power for quad channel. |
| Output Drive | ±80 mA (1 V from rail) - Drives 60-Ω loads directly, eliminating need for external buffers in DAC output stages. |
| Shutdown Current / Channel | 0.3 µA typ - Reduces total system idle power to <1.2 µA when two channels are disabled. |
| CMRR | 60 dB min (−40°C to 125°C) - Maintains >1000:1 rejection of supply ripple in single-supply sensor amplifiers. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464ID | Same architecture and pinout, but rated for −40°C to 125°C with 2000-µV max VIO (vs. 1500 µV for TLV2464AID). | Acceptable where 0.08% VIO-induced error is tolerable in automotive cabin modules. | Select TLV2464ID only if cost sensitivity outweighs precision requirement; TLV2464AID preferred for metrology or high-accuracy sensor nodes. |
| OPA4340UA | Higher precision (125-µV max VIO), lower noise (8 nV/√Hz), but higher supply current (750 µA/ch) and no shutdown. | Better for ultra-low-error medical or test equipment; unsuitable where dynamic power gating is required. | Choose OPA4340UA when VIO <150 µV is mandatory and shutdown is unnecessary; TLV2464AID remains optimal for power-constrained automotive designs. |
Compared with TLV2464ID, TLV2464AID offers tighter input offset (1500 µV vs. 2000 µV) for improved DC accuracy in wide-temperature industrial sensors; compared with OPA4340UA, it trades 125-µV precision for 40% lower quiescent power and integrated shutdown-critical for battery-operated IoT endpoints.

FAQ
What is the maximum operating temperature range for TLV2464AID?
The TLV2464AID is specified for continuous operation from −40°C to +125°C ambient temperature. This rating is validated per TI's automotive qualification standards and includes guaranteed performance for parameters including input offset voltage (1500 µV max), CMRR (60 dB min), and supply current (0.9 mA max per channel) across the full range.
Does TLV2464AID support true rail-to-rail input and output simultaneously?
Yes, TLV2464AID supports rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 100 mV of each rail at ±10 mA). This allows full utilization of 3.3-V or 5-V supplies in single-ended configurations without clipping-critical for ADC driver applications where headroom is constrained.
How does the shutdown function work on TLV2464AID?
TLV2464AID features two independent shutdown controls: pin 1 (1/2SHDN) disables Channels 1 and 2; pin 13 (3/4SHDN) disables Channels 3 and 4. Driving either pin below 0.7 V places the associated pair in ultralow-current mode (0.3 µA per channel), while forcing outputs into high-impedance state-enabling selective channel power gating in multi-sensor systems.
What package type is used for TLV2464AID and what are its thermal characteristics?
TLV2464AID uses the TSSOP-14 (PW) package. Its thermal resistance is θJA = 173.6°C/W and θJC = 29.3°C/W. At TA = 25°C, maximum power dissipation is 720 mW; this derates linearly to 144 mW at TA = 125°C. The exposed thermal pad is not electrically connected but improves board-level heat transfer when soldered to a copper pour.
Can TLV2464AID drive capacitive loads, and what is the stability limit?
TLV2464AID is stable driving up to 160 pF capacitive load with 10 kΩ series resistance (per Figure 14). Phase margin remains ≥44° under these conditions. For loads >160 pF, external isolation resistor (≥100 Ω) is required between output and capacitance to prevent peaking or oscillation-verified in TI's SLOS220J datasheet Figure 36.
