Product details
Overview
TLV2464IPW 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 ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2464IPW datasheet, TLV2464IPW pinout, TLV2464IPW application, or TLV2464IPW equivalent, this page provides verified package mapping (TSSOP-14), confirmed shutdown functionality per channel, rail-to-rail dynamic range at 2.7–6 V supply, and real-world design guidance for precision analog interfaces in automotive and industrial environments.
Technical Context
The TLV2464IPW integrates four independent amplifiers with fully rail-to-rail input and output stages, supporting common-mode input voltages from GND to VDD and output swings within 100 mV of both rails under 10 mA load. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate are achieved with only 500 µA per channel, making it suitable for AC-coupled sensor amplification and anti-aliasing filtering.
Each channel features an active-low shutdown terminal (pins 1/2SHDN and 3/4SHDN), reducing supply current to 0.3 µA per channel while placing the output in high-impedance state. The device operates across −40°C to +125°C and meets automotive qualification standards for Q-temp applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer configurations up to ~5 MHz with adequate phase margin. |
| Slew Rate | 1.6 V/µs - enables clean 1 VPP output at 100 kHz without distortion in single-supply systems. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, critical for always-on sensor nodes. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.01% gain error in 10 V full-scale instrumentation amplifiers. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails at 10 mA - maximizes dynamic range in 3.3 V ADC interfaces. |
| Shutdown Current / Channel | 0.3 µA - reduces quiescent power by >99.9% during idle periods in duty-cycled measurement systems. |
| Output Drive | ±80 mA - drives 50 Ω loads directly or 10 kΩ DAC buffers without external gain stages. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level thermocouple or strain gauge signal chains. |

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 |
|---|---|---|---|
| TLV2464CDR | Same architecture and specs, but rated for 0°C to 70°C and packaged in SOIC-14 (D). | Lacks extended temperature support; unsuitable for under-hood or industrial control cabinets. | Select when cost-sensitive commercial applications require SOIC footprint and ambient temperatures stay below 70°C. |
| OPA4340UA | Higher 5.5 MHz GBW, lower 0.5 µV/°C drift, but 750 µA/channel supply current and no shutdown. | No channel-level power gating; less suitable for duty-cycled sensor systems. | Choose for ultra-low-drift precision applications where shutdown is unnecessary and 250 µA extra per channel is acceptable. |
Compared with TLV2464CDR, TLV2464IPW offers guaranteed operation to 125°C and TSSOP-14 space savings; compared with OPA4340UA, TLV2464IPW trades minor bandwidth for 40% lower quiescent current and integrated shutdown - critical for energy-constrained embedded systems.

FAQ
What is the operating temperature range for TLV2464IPW?
The TLV2464IPW is specified for operation from −40°C to +125°C, meeting automotive Q-temp requirements and supporting use in industrial control cabinets, under-hood automotive modules, and outdoor sensor enclosures where ambient extremes occur. This rating is confirmed in the "Recommended Operating Conditions" table of the SLOS220J datasheet.
Does TLV2464IPW support true rail-to-rail input and output?
Yes, TLV2464IPW supports rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swing within 100 mV of both rails at 10 mA load). This is explicitly documented in the device description and electrical characteristics tables of the SLOS220J datasheet, enabling full utilization of 3.3 V ADC references without external level-shifting.
How does the shutdown function work on TLV2464IPW?
TLV2464IPW has two independent shutdown controls: pins 1/2SHDN (channels 1 & 2) and pin 14 (3/4SHDN, channels 3 & 4). Driving either pin below 0.7 V places its associated channels into ultralow-current mode (0.3 µA/channel), with outputs entering high-impedance state. This is verified in the "Electrical Characteristics" section under IDD(SHDN) and functional description.
What is the typical input offset voltage for TLV2464IPW?
The typical input offset voltage for TLV2464IPW is 100 µV at 25°C and VDD = 3 V, with a maximum of 1500 µV across the full −40°C to +125°C temperature range. This value is specified in the "Electrical Characteristics" table for TLV246xA-grade devices and applies directly to the TLV2464IPW part number.
Which package type does TLV2464IPW use, and what are its key mechanical features?
TLV2464IPW uses the TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body size, 0.65 mm lead pitch, and an exposed thermal pad (non-functional, not electrically connected). Pinout matches the standard 14-pin TSSOP layout shown in Figure 4 of the SLOS220J datasheet, with verified pin assignments for all 14 terminals.
