Product details
Overview
TLV2465CPWR 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 ADC inputs in battery-powered systems.
For engineers reviewing the TLV2465CPWR datasheet, TLV2465CPWR pinout, TLV2465CPWR application, or TLV2465CPWR equivalent, this page provides verified technical context, package-specific pin definitions, real-world use cases in sensor front-ends and data acquisition, and validated alternative options for design continuity.
Technical Context
The TLV2465CPWR implements a CMOS input stage with rail-to-rail input common-mode range extending beyond VDD and GND, supporting full dynamic range in single-supply 2.7–6 V systems. Its output stage delivers true rail-to-rail swing with ±80 mA sourcing/sinking capability at 1 V from rails - overcoming headroom limitations of legacy rail-to-rail op amps.
Each of its four amplifiers integrates an independent shutdown terminal (pins 1/2SHDN and 3/4SHDN), reducing per-channel quiescent current to 0.3 µA when asserted. The device is specified across −40°C to 125°C (I-suffix) and supports stable operation with capacitive loads up to 160 pF at unity gain.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz with moderate gain (e.g., AV = 10) in precision signal paths. |
| Slew Rate | 1.6 V/µs - supports clean 10-bit+ ADC driving at ≥100 kSPS without distortion in buffered configurations. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.001% gain error in 10 V full-scale instrumentation amplifiers. |
| Supply Current / Channel | 500 µA - allows 4-channel operation at <2 mA total, critical for always-on sensor nodes. |
| Rail-to-Rail I/O | Input extends beyond rails; output swings within 10 mV of VDD/GND - maximizes usable signal range in 3.3 V systems. |
| Shutdown Current / Channel | 0.3 µA - reduces system standby power by >99.9% versus active mode, enabling ultra-low-power wake-up architectures. |
| Output Drive | ±80 mA - directly drives 50 Ω transmission lines or multiple 10 kΩ ADC inputs without external buffers. |

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 |
|---|---|---|---|
| TLV2465IPWR | Same electrical specs but rated for −40°C to 125°C (I-suffix) vs. 0°C to 70°C (C-suffix); higher max input offset (1500 µV vs. 2000 µV). | Required for automotive under-hood or industrial ambient environments exceeding 70°C. | Select TLV2465IPWR when extended temperature operation is mandatory; otherwise TLV2465CPWR suffices for commercial-grade designs. |
| OPA4340UA | Lower input offset (125 µV typ), lower noise (8 nV/√Hz), but higher supply current (750 µA/ch) and no shutdown function. | Better DC precision needed, but no requirement for ultra-low-power sleep states. | Choose OPA4340UA only when offset and noise dominate over power budget; TLV2465CPWR remains superior for battery-constrained systems. |
Compared with TLV2465IPWR, TLV2465CPWR trades extended temperature range for lower cost and sufficient performance in commercial environments; compared with OPA4340UA, it adds shutdown capability and cuts active current by 33%, making it optimal for intermittent-sampling architectures.

FAQ
What is the operating temperature range for TLV2465CPWR?
The TLV2465CPWR is rated for 0°C to 70°C (C-suffix). This commercial temperature range is validated per TI's SLOS220J datasheet and applies to all electrical specifications unless otherwise noted. For extended-range applications, consider TLV2465IPWR (−40°C to 125°C).
Does TLV2465CPWR support true rail-to-rail input and output?
Yes, TLV2465CPWR supports rail-to-rail input common-mode voltage range (extending 0.2 V beyond VDD and GND) and rail-to-rail output swing (within 10 mV of both rails under light load). This is confirmed in the "Features" and "Electrical Characteristics" sections of the TI datasheet.
How does the shutdown function work on TLV2465CPWR?
TLV2465CPWR has two independent shutdown controls: pins 1/2SHDN (channels 1 & 2) and pins 14/3/4SHDN (channels 3 & 4). Driving either pin below 0.7 V places its associated amplifiers into ultralow-current mode (0.3 µA/channel) and forces outputs into high-impedance state.
What is the maximum capacitive load TLV2465CPWR can drive stably?
TLV2465CPWR maintains stability with up to 160 pF capacitive load at unity gain, as verified in the "Operating Characteristics" table (SLOS220J, pg. 8–10). For loads >100 pF, TI recommends using a series resistor (≥10 Ω) between output and capacitance to ensure phase margin >44°.
Is TLV2465CPWR pin-compatible with other TLV246x variants?
Yes - TLV2465CPWR uses the standard TSSOP-16 pinout defined for the TLV246x family (SLOS220J, pg. 4–5). All TLV2465x variants (C/I/A/Q/M suffixes) share identical pin functions and physical layout; only temperature grade, offset, and reliability qualifications differ.
