Product details
Overview
TLV2461CD from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-voltage portable systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage - enabling high-fidelity analog signal buffering in ADC front-ends and sensor interfaces.
For engineers reviewing the TLV2461CD datasheet, TLV2461CD pinout, TLV2461CD application, or TLV2461CD equivalent, this device is selected for precision, low-power, rail-to-rail performance in battery-powered instrumentation, industrial sensor conditioning, and automotive body electronics where supply headroom is constrained to 2.7–6 V.
Technical Context
The TLV2461CD employs a CMOS input stage with rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing, supporting full dynamic range in single-supply configurations down to 2.7 V. Its internal architecture enables stable unity-gain operation with up to 160 pF capacitive load while maintaining ≥44° phase margin.
It integrates a dedicated shutdown terminal (SHDN) that reduces supply current to 0.3 µA/channel and places the output in high-impedance state - critical for power-gated signal chains in always-on monitoring systems. DC precision is maintained across −40°C to 125°C (I-suffix temperature grade), with input offset drift of only 2 µV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - supports stable closed-loop operation up to ~1 MHz at unity gain with minimal phase loss. |
| Slew Rate | 1.6 V/µs - enables clean 100-kHz full-scale sine wave output into 10 kΩ load without distortion. |
| Supply Current per Channel | 500 µA - allows continuous operation for >1 year on a single CR2032 coin cell in low-duty-cycle sensing nodes. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5-V full-scale 12-bit ADC driver applications. |
| Rail-to-Rail I/O | Input range: 0 V to VDD; Output swing: within 100 mV of rails - maximizes usable signal range in 3.3-V systems. |
| Output Drive Capability | ±80 mA - directly drives 50-Ω transmission lines or multiple parallel inputs without external buffers. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power to sub-microwatt levels during sleep modes. |
Pinout & Package
TLV2461CD is housed in an 8-pin SOIC (D) package with standard pin spacing (1.27 mm), suitable for automated assembly and thermal management in industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage with ±80 mA sourcing/sinking capability; high-impedance in shutdown mode. |
| 2 (IN−) | Inverting input | CMOS input with 1.3 nA bias current (typ @ 5 V); supports differential or single-ended configurations. |
| 3 (IN+) | Non-inverting input | CMOS input with identical bias characteristics; enables precision instrumentation amplifier topologies. |
| 4 (GND) | Analog ground reference | Primary return path for input bias, output current, and shutdown control; must be low-impedance. |
| 5 (NC) | No internal connection | Unbonded pad; electrically isolated - no routing or grounding required. |
| 6 (SHDN) | Shutdown control input | Active-high logic: ≥2 V enables operation; ≤0.7 V disables amplifier and forces output high-Z. |
| 7 (VDD+) | Positive supply rail | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; decoupling capacitor mandatory at pin. |
| 8 (NC) | No internal connection | Unbonded pad; electrically isolated - no routing or grounding required. |

| Industrial Process Transmitters | Smart Energy Metering |
|
Use Scenario: Isolated 4–20 mA loop transmitter front-end with RTD or thermocouple interface. IC Role / Device Role / Timing Role: Low-drift, low-power instrumentation amplifier stage preceding DAC and current sink. Use Value: 2 µV/°C offset drift minimizes temperature-induced gain error; ±80 mA output drives 25 Ω loop impedance robustly. |
Use Scenario: Anti-aliasing and gain-stage amplification for shunt-based current sensing in Class 0.5 meters. IC Role / Device Role / Timing Role: High-precision, low-noise signal conditioner feeding metrology-grade ADC (e.g., ADS131M04).

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461ID | Identical electrical specs but rated for −40°C to 125°C (I-suffix) vs. 0°C to 70°C (C-suffix). | Required for under-hood automotive or industrial environments exceeding 70°C ambient. | Select TLV2461ID when extended temperature operation is mandatory; otherwise TLV2461CD suffices for commercial indoor use. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. 2 µV/°C; 17 µV max offset vs. 2000 µV; higher 350 µA supply current. | Better for ultra-precision DC-coupled applications (e.g., weigh scales), but less optimal for AC signal fidelity due to chopper artifacts. | Choose OPA333AIDBVR only when sub-10 µV offset stability over time/temperature outweighs cost and potential 100-kHz noise peaks. |
Compared with TLV2461ID, TLV2461CD trades extended temperature range for lower cost and qualification scope; compared with OPA333AIDBVR, it offers superior AC performance and lower supply current at the expense of long-term DC drift - making TLV2461CD optimal for cost-sensitive, wideband, battery-constrained signal conditioning.

FAQ
What is the maximum supply voltage for TLV2461CD?
The absolute maximum supply voltage for TLV2461CD is 6 V. Operation above this level risks permanent damage. Recommended operating range is 2.7 V to 6 V for single-supply use, or ±1.35 V to ±3 V for split-supply configurations. Exceeding 6 V violates absolute maximum ratings even momentarily.
Does TLV2461CD support true rail-to-rail input and output?
Yes, TLV2461CD supports rail-to-rail input (common-mode range extends from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails under 10-kΩ load). This is confirmed in the datasheet's "Rail-to-Rail Output Swing" headline and electrical characteristics tables for VOH/VOL across temperature and supply conditions.
What is the shutdown behavior of TLV2461CD?
When SHDN pin voltage drops ≤0.7 V, TLV2461CD enters ultralow-power shutdown mode drawing only 0.3 µA/channel, and its output transitions to high-impedance state. The amplifier resumes normal operation within 7.65 µs after SHDN rises ≥2 V - verified in the "Operating Characteristics" table under t(on).
Is TLV2461CD qualified for automotive applications?
TLV2461CD carries the C-suffix, specifying operation from 0°C to 70°C - suitable for commercial/indoor automotive cabin modules (e.g., infotainment sensors), but not under-hood applications. For full AEC-Q100 compliance and −40°C to 125°C operation, TI recommends TLV2461ID or TLV2461AQD variants instead of TLV2461CD.
What package type is used for TLV2461CD?
TLV2461CD is supplied in an 8-pin SOIC (Small Outline Integrated Circuit) package, designated as "D" in TI's packaging nomenclature. Pinout matches standard SOIC-8 layout with NC pins at positions 5 and 8, and includes dedicated SHDN control on pin 6 - confirmed in the "TLV246x PACKAGE PINOUTS" section of the datasheet.
