Product details
Overview
TLV2464AIPW 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 precision ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464AIPW datasheet, TLV2464AIPW pinout, TLV2464AIPW application, or TLV2464AIPW equivalent, this device is selected for rail-to-rail dynamic range, micropower shutdown (0.3 µA/channel), and operation across −40°C to 125°C - critical for automotive sensor interfaces, industrial data acquisition, and portable medical instrumentation.
Technical Context
The TLV2464AIPW integrates four independent amplifiers with rail-to-rail input common-mode range extending beyond supply rails (0 V to VDD) and rail-to-rail output swing delivering full dynamic range at low supply voltages (2.7–6 V). Its architecture supports high-output-drive capability without sacrificing DC precision or noise performance.
Each channel features an active shutdown terminal (SHDN) that reduces supply current to 0.3 µA per channel while placing the output in high-impedance state. The device maintains 11 nV/√Hz input voltage noise and 60 dB CMRR over frequency, making it suitable for high-resolution analog signal chains where power, accuracy, and stability are co-constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Slew Rate | 1.6 V/µs - supports fast settling for 12-bit ADC driving with <2 µs 0.1% settling time at 2 V step. |
| Supply Current / Channel | 500 µA - allows four-channel operation under 2 mA total, ideal for always-on sensor nodes. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.0025% error in 4 V full-scale precision measurement paths. |

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 |
|---|---|---|---|
| TLV2464CDR | Same architecture, but rated only for 0°C to 70°C; 2000 µV max VIO vs. 1500 µV for TLV2464AIPW. | Limited to commercial-grade consumer electronics; not qualified for automotive or extended-temp industrial use. | Select when cost sensitivity outweighs temperature range and offset voltage requirements. |
| OPA4340UA | Higher precision (50 µV VIO), lower noise (8 nV/√Hz), but 750 µA/channel supply current and no shutdown. | Better for metrology-grade instruments; lacks power-gating capability needed in battery-operated systems. | Choose when ultra-low offset and noise dominate over power budget and thermal robustness. |
Compared with TLV2464CDR, TLV2464AIPW provides guaranteed performance over −40°C to 125°C and tighter offset spec - essential for automotive and industrial deployments. Versus OPA4340UA, TLV2464AIPW trades minor noise/offset degradation for 33% lower quiescent current and integrated shutdown, enabling energy-aware system architectures.

FAQ
What is the maximum supply voltage rating for TLV2464AIPW?
The absolute maximum supply voltage for TLV2464AIPW 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 specified electrical characteristics. At 6 V, output swing remains within 100 mV of rails at ±10 mA load, and supply current increases to 0.65 mA/channel.
Does TLV2464AIPW support true rail-to-rail input common-mode range?
Yes, TLV2464AIPW supports rail-to-rail input common-mode voltage range from 0 V to VDD. This is confirmed in the datasheet's recommended operating conditions and typical characteristics (Figures 1–2), where input offset voltage remains stable across the full supply range - enabling direct interfacing with sensors and DACs operating near supply rails.
How does the shutdown function work on TLV2464AIPW?
TLV2464AIPW uses two dedicated shutdown pins: pin 12 (1/2 SHDN) controls channels A and B; pin 14 (3/4 SHDN) controls channels C and D. Driving either pin below 0.7 V places its associated pair into ultralow-current shutdown (0.3 µA/channel), with output forced to high-impedance state. Logic-high (>2 V) re-enables normal operation with 7.65 µs turn-on time.
What is the output drive capability of TLV2464AIPW at 3 V supply?
At VDD = 3 V, TLV2464AIPW delivers ±40 mA output current (measured 1 V from rail), with high-level output voltage ≥2.8 V and low-level output voltage ≤0.2 V at 10 mA sink/source. This enables direct driving of medium-impedance loads like ADC reference buffers and analog switches without external boost stages.
Is TLV2464AIPW pin-compatible with other devices in the TLV246x family?
TLV2464AIPW is pin-compatible with TLV2464CDR, TLV2464IDR, and TLV2464AIDR in the TSSOP-14 (PW) package. All share identical pinout per Figure 4 of SLOS220J. However, it is not pin-compatible with TLV2462 (MSOP-8) or TLV2460 (SOT-23-6) variants due to differing channel count and package geometry.
