Product details
Overview
TLV2461CDBVT from Texas Instruments is a single-channel, 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, 100 µV max input offset voltage (at 25°C), and 11 nV/√Hz input noise voltage at 1 kHz - enabling high-fidelity buffering of precision ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLV2461CDBVT datasheet, TLV2461CDBVT pinout, TLV2461CDBVT application, or TLV2461CDBVT equivalent, this device is selected for low-voltage (2.7–6 V), rail-to-rail dynamic range, micropower shutdown (0.3 µA/channel), and robust output drive in space-constrained SOT-23-5 designs requiring stable DC accuracy and AC performance.
Technical Context
The TLV2461CDBVT employs a CMOS input stage with rail-to-rail common-mode input range extending beyond supply rails (0 V to VDD) and rail-to-rail output swing capable of sourcing/sinking ±80 mA. Its internal architecture supports stable unity-gain operation with 160 pF capacitive load and provides 45° phase margin at 5 V supply.
It integrates a dedicated shutdown terminal (SHDN) that places the amplifier in ultralow-current mode (0.3 µA/channel) while forcing output into high-impedance state - critical for power-gated signal chains in multi-stage analog systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable closed-loop operation up to ~500 kHz at gain = 10 without excessive phase lag. |
| Slew Rate | 1.6 V/µs - supports clean 100-kHz, 1-VPP sine wave output with <0.01% THD+N at 5 V supply. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.002% gain error in 5-V full-scale instrumentation amplifiers. |
| Supply Current | 500 µA/channel - allows continuous operation for >1 year on a 200-mAh coin cell in always-on sensor nodes. |
| Output Drive | ±80 mA - directly drives 60-Ω loads (e.g., coaxial cable termination) without external buffers. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode in duty-cycled measurement systems. |
| Input Noise Voltage | 11 nV/√Hz at 1 kHz - contributes <1.1 µVRMS integrated noise in 10-kHz bandwidth, preserving 16-bit ADC ENOB. |
Pinout & Package
SOT-23-5 package (DBV): 2.9 mm × 1.6 mm × 1.15 mm, surface-mount, tape-and-reel compatible. RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing (0 V to VDD) with ±80 mA drive capability; connects directly to ADC input or filter network. |
| 2 - GND | Analog ground reference | Primary return path for input bias current and output current; must be tied to low-impedance system ground plane. |
| 3 - IN+ | Non-inverting input | CMOS input with 1.3 nA max bias current at 25°C; accepts common-mode voltages from 0 V to VDD. |
| 4 - VDD+ | Positive supply | Operates from 2.7 V to 6 V single supply; decoupling capacitor (0.1 µF) required within 5 mm of this pin. |
| 5 - IN− | Inverting input | Differential input node; matched to IN+ for <100 µV offset; sensitive to PCB leakage and parasitic capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full 0–VDD dynamic range in single-supply systems - eliminates level-shifting circuitry for 3.3-V ADC interfacing. |

| High output drive | ±80 mA output current supports direct driving of 50-Ω transmission lines or multiple parallel inputs without gain degradation. |
| Low input noise | 11 nV/√Hz at 1 kHz ensures minimal SNR degradation in precision sensor signal chains (e.g., strain gauge, thermopile). |
| Wide temperature range | Specified from 0°C to 70°C (C-suffix) - validated for commercial-grade embedded systems including HVAC controls and portable test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVT | Same electrical specs but rated for −40°C to 125°C operating range; 1500 µV max VIO over full temp range vs. 2000 µV for C-suffix. | Required for under-hood automotive or industrial control environments where ambient exceeds 70°C. | Select TLV2461IDBVT when extended temperature operation is mandatory; otherwise TLV2461CDBVT offers cost advantage for commercial-grade designs. |
| OPA333AIDBVT | Zero-drift architecture; 0.1 µV/°C max drift vs. 2 µV/°C for TLV2461; 17 µV max VIO vs. 100 µV; higher 350-µA supply current. | Better for ultra-stable DC-coupled applications (e.g., precision weight scales) where long-term offset drift dominates error budget. | Choose OPA333AIDBVT only if sub-µV/°C drift is required; TLV2461CDBVT remains optimal for AC-coupled or moderate-accuracy DC systems with strict power constraints. |
Compared with TLV2461IDBVT, TLV2461CDBVT trades extended temperature rating for lower cost and identical room-temperature precision; compared with OPA333AIDBVT, it sacrifices zero-drift stability for 40% lower supply current and simpler compensation in high-speed buffered configurations.

FAQ
What is the maximum supply voltage for TLV2461CDBVT?
The absolute maximum supply voltage for TLV2461CDBVT is 6 V. Operation above this level risks permanent damage. The recommended operating range is 2.7 V to 6 V single supply (or ±1.35 V to ±3 V dual supply), with optimal AC performance observed at 3 V and 5 V per the datasheet's electrical characteristics tables.
Does TLV2461CDBVT support rail-to-rail input and output simultaneously?
Yes, TLV2461CDBVT supports true rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 10 mV of each rail under light load). This allows full utilization of the supply voltage in single-supply configurations - for example, delivering 0–3.3 V output from a 3.3-V supply while accepting input signals from 0 V to 3.3 V.
How does the shutdown function work on TLV2461CDBVT?
The SHDN pin (Pin 5) enables ultralow-power mode: applying <0.7 V places TLV2461CDBVT in shutdown with 0.3 µA/channel supply current and high-impedance output. Applying >2 V activates normal operation. No external pull-up is required; the pin is CMOS-compatible and draws negligible current in either state.
What is the typical input bias current of TLV2461CDBVT at 25°C?
The typical input bias current of TLV2461CDBVT is 1.3 nA at 25°C and 3 V supply, with a maximum of 25 nA over the full 0°C to 70°C operating range. This low bias current minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes or photodiode transimpedance stages).
Can TLV2461CDBVT drive a 10-kΩ load with 1-VPP output at 100 kHz?
Yes - TLV2461CDBVT maintains <0.01% THD+N at 100 kHz with 1-VPP output into 10-kΩ, per typical characteristics (Figure 34). Its 6.4 MHz GBW and 1.6 V/µs slew rate ensure linear operation well beyond this condition, making it suitable for anti-aliasing and reconstruction filtering in medium-speed data acquisition.
