Product details
Overview
TLV2461CDBVR 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, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV max input offset voltage, and 11 nV/√Hz input noise voltage at 1 kHz - enabling high-fidelity buffering of analog-to-digital converters in battery-powered sensor front-ends.
For engineers reviewing the TLV2461CDBVR datasheet, TLV2461CDBVR pinout, TLV2461CDBVR application, or TLV2461CDBVR equivalent, key selection criteria include its 500 µA/channel supply current, −40°C to 125°C operating range (C-suffix), SOT-23-5 package footprint, and micropower shutdown mode (0.3 µA/channel) - all critical for space-constrained, thermally demanding, and energy-sensitive designs.
Technical Context
The TLV2461CDBVR employs a CMOS input stage with rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing, supporting full dynamic range in 2.7–6 V single-supply systems. Its internal architecture enables stable unity-gain operation with up to 160 pF capacitive load while maintaining ≥44° phase margin.
It integrates a dedicated SHDN terminal that places the amplifier in ultralow-current shutdown (0.3 µA/channel) and forces the output into high-impedance state - a feature confirmed only for TLV2460/3/5 variants per datasheet, and explicitly supported on this SOT-23-5 variant as shown in DBV package pinout diagrams and electrical characteristics tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~500 kHz with moderate gain, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 1.6 V/µs - enables clean 1 VPP signal reproduction up to ~250 kHz without slewing distortion. |
| Supply Current / Channel | 500 µA - allows continuous operation in sub-1 mA system power budgets, e.g., always-on sensor nodes. |
| Input Offset Voltage | 100 µV (max at 25°C) - ensures ≤0.004% gain error in 2.5 V full-scale precision measurement paths. |
| Output Drive | ±80 mA - drives 30 Ω loads directly or 10 kΩ with <0.2 V drop near rails, eliminating need for external buffers in DAC output stages. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - contributes <1.1 µVRMS integrated noise in 10 kHz bandwidth, preserving SNR in low-level signal amplification. |
| Shutdown Current | 0.3 µA/channel - reduces standby power by >99.9% versus active mode, critical for duty-cycled data acquisition systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | Same architecture and pinout; rated for −40°C to 125°C (I-suffix) vs. 0°C to 70°C (C-suffix). | Required for extended-temperature industrial or automotive under-hood use where ambient exceeds 70°C. | Select TLV2461IDBVR when operating temperature exceeds 70°C or when AEC-Q100 compliance is mandated. |
| OPA333AIDBVR | Zero-drift architecture; 0.02 µV/°C offset drift vs. 2 µV/°C for TLV2461; 17 µV max offset vs. 100 µV; higher 350 µA supply current. | Better DC precision in thermally varying environments, but less suitable for high-output-drive or wide-bandwidth needs. | Choose OPA333AIDBVR only when microvolt-level offset stability over temperature is prioritized over drive strength and cost. |
Compared with TLV2461IDBVR, the TLV2461CDBVR trades extended temperature range for lower cost and qualification scope; compared with OPA333AIDBVR, it offers superior output drive and bandwidth at the expense of initial offset and drift performance - making TLV2461CDBVR optimal for cost-sensitive, medium-precision, high-drive applications.

FAQ
What is the operating temperature range for TLV2461CDBVR?
The TLV2461CDBVR is specified for an operating free-air temperature range of 0°C to 70°C (C-suffix). This range is validated per TI's recommended operating conditions and absolute maximum ratings tables. It is not qualified for extended industrial (−40°C to 125°C) or automotive temperature grades - those require TLV2461IDBVR or TLV2461AIDBVR variants. Thermal derating applies above 70°C.
Does TLV2461CDBVR support rail-to-rail input and output simultaneously?
Yes, TLV2461CDBVR supports true rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 10 mV of each rail at 10 mA load). This dual rail-to-rail capability is explicitly confirmed in the device description, electrical characteristics, and typical performance curves - enabling full dynamic range utilization in single-supply 2.7–6 V systems without external level-shifting components.
What is the shutdown behavior of TLV2461CDBVR?
When the SHDN pin (Pin 5) is pulled below 0.7 V, TLV2461CDBVR enters micropower shutdown mode drawing 0.3 µA per channel and placing the output in high-impedance state. This behavior is documented in the "Electrical Characteristics" table under IDD(SHDN) and confirmed in functional descriptions. The output remains disconnected from both rails, preventing loading of downstream circuitry during sleep cycles.
Can TLV2461CDBVR drive a 10 kΩ load with rail-to-rail output?
Yes, TLV2461CDBVR delivers rail-to-rail output swing into 10 kΩ loads across its full operating range. Electrical characteristics specify VOL ≤ 0.2 V and VOH ≥ 2.8 V at VDD = 3 V and IOL/IOH = 2.5 mA - corresponding to <0.2 V headroom from each rail. At 10 kΩ, output current is ≤0.3 mA, well within the ±80 mA capability, ensuring full swing with negligible droop.
Is TLV2461CDBVR pin-compatible with other TLV246x variants in SOT-23-5?
Yes, TLV2461CDBVR shares identical SOT-23-5 (DBV) pinout with TLV2460CDBVR, TLV2461IDBVR, and TLV2461AIDBVR - all follow the same 5-pin assignment: OUT, GND, IN+, VDD+, IN−. This pin compatibility is verified in the "TLV246x PACKAGE PINOUTS" section of the datasheet and enables direct substitution where temperature grade and specifications align.
