Product details
Overview
TLV2464CPW 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 TLV2464CPW datasheet, TLV2464CPW pinout, TLV2464CPW application, or TLV2464CPW 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 direct alternatives with documented performance trade-offs in precision, power, and temperature range.
Technical Context
The TLV2464CPW integrates four independent amplifiers sharing a common shutdown control line (pin 1/2SHDN and pin 13/3/4SHDN), enabling synchronized entry into ultralow-current mode (0.3 µA/channel). Its rail-to-rail input stage extends beyond supply rails, while the output stage drives ±80 mA within 1 V of either rail - critical for maximizing dynamic range in single-supply 3 V systems.
Each amplifier features 11 nV/√Hz input noise at 1 kHz and 6.4 MHz unity-gain bandwidth at VDD = 5 V, supporting stable closed-loop operation with capacitive loads up to 160 pF. Phase margin remains ≥44° under typical conditions (RL = 10 kΩ, CL = 160 pF), ensuring robust stability without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable unity-gain buffer or gain-of-10 configurations up to ~640 kHz with adequate phase margin. |
| Slew Rate | 1.6 V/µs - enables faithful reproduction of 100-kHz full-scale sine waves at 1-Vpp without slew-induced distortion. |
| Supply Current / Channel | 500 µA - allows four-channel operation at <2 mA total, suitable for always-on sensor interface stages in energy-constrained designs. |
| Input Offset Voltage | 100 µV (typ) - contributes ≤0.003% error in 3.3-V full-scale 12-bit ADC driver applications. |
| Output Drive | ±80 mA - directly drives 37.5-Ω loads (e.g., 75-Ω coax with termination) or multiple CMOS inputs without external buffers. |
| Rail-to-Rail I/O | Full swing from VDD to GND - preserves >99% of available voltage headroom in 3-V systems, maximizing SNR in ADC front-ends. |
| Shutdown Current | 0.3 µA/channel - reduces quiescent power by >99.9% when inactive, ideal for duty-cycled measurement cycles. |

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 |
|---|---|---|---|
| TLV2464IPW | Same architecture and pinout; rated for −40°C to 125°C (I-suffix) vs. 0°C to 70°C (C-suffix); VIO max = 1500 µV vs. 2000 µV. | Required for automotive under-hood or industrial control cabinet deployments where extended temperature operation is mandatory. | Select TLV2464IPW when operating beyond 70°C ambient or requiring AEC-Q100 alignment via TI's Q-temp qualification path. |
| OPA4340UA | Lower noise (8 nV/√Hz), higher GBW (5.5 MHz), but higher supply current (750 µA/ch); no shutdown function; SO-14 package only. | Preferred where ultra-low noise dominates over power savings, and continuous operation eliminates need for shutdown control. | Choose OPA4340UA for high-resolution weigh scale or precision weighbridge applications where 0.001% linearity outweighs 50% higher quiescent power. |
Compared with TLV2464IPW, the TLV2464CPW trades extended temperature rating and tighter VIO for lower cost and sufficient performance in commercial-grade portable instruments; versus OPA4340UA, it offers integrated shutdown and 30% lower supply current at the expense of 27% higher input noise.

FAQ
What is the operating temperature range for TLV2464CPW?
The TLV2464CPW is characterized for operation from 0°C to 70°C (C-suffix grade). It is not rated for industrial (−40°C to 125°C) or automotive temperature ranges. For those environments, TI specifies the TLV2464IPW (I-suffix) or TLV2464AIPW (AI-suffix) variants, which undergo extended temperature testing and screening.
Does TLV2464CPW support true rail-to-rail input and output?
Yes, TLV2464CPW supports rail-to-rail input - its common-mode voltage range extends 200 mV beyond both supply rails - and rail-to-rail output - delivering full swing from GND to VDD with ±80 mA drive capability. This is confirmed in the datasheet's "Rail-to-Rail Output Swing" headline and electrical characteristics tables for VOH/VOL across load conditions.
How many independent shutdown controls does TLV2464CPW have?
The TLV2464CPW has two independent shutdown control inputs: pin 1 (1/2SHDN) disables Amplifiers 1 and 2, while pin 12 (3/4SHDN) disables Amplifiers 3 and 4. Each control is active-high; pulling the pin below 0.7 V releases shutdown, and pulling above 2 V asserts it. This dual-control architecture enables flexible power management in multi-channel signal chains.
What is the typical input offset voltage for TLV2464CPW at 25°C?
The typical input offset voltage for TLV2464CPW at 25°C and VDD = 3 V is 100 µV, as stated in the "Electrical Characteristics" table on page 7 of the SLOS220J datasheet. The maximum guaranteed value across the 0°C to 70°C range is 2000 µV, consistent with its C-suffix commercial-grade specification.
Can TLV2464CPW drive a 10-kΩ load with rail-to-rail output swing?
Yes, TLV2464CPW can drive a 10-kΩ load with rail-to-rail output swing: at VDD = 3 V, VOH = 2.8 V (min) and VOL = 0.2 V (max) under 2.5-mA load conditions - representing <0.1 V from each rail. At lighter loads (e.g., 10-kΩ), output swing improves further, achieving true 0–3 V swing with <10-mV droop, as verified in Figure 5 and 7 of the datasheet.
