Product details
Overview
TLV2461AIDR from Texas Instruments is a single-channel rail-to-rail input/output operational amplifier optimized for low-power portable and automotive applications. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV input offset voltage, and 11 nV/√Hz input noise voltage at 1 kHz - enabling high-fidelity analog signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2461AIDR datasheet, TLV2461AIDR pinout, TLV2461AIDR application, or TLV2461AIDR equivalent, key selection considerations include its −40°C to 125°C temperature rating, micropower shutdown mode (0.3 µA/channel), rail-to-rail output swing down to 100 mV from rails at ±10 mA, and compatibility with 2.7–6 V single-supply operation in space-constrained industrial and automotive systems.
Technical Context
The TLV2461AIDR employs a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and ultra-low input bias current (≤75 nA over full temperature range). Its output stage supports true rail-to-rail swing with high-current capability (±80 mA at VDD = 5 V), overcoming limitations of earlier rail-to-rail op-amps in driving capacitive loads or low-impedance sensors.
It integrates a dedicated shutdown terminal (SHDN) that places the amplifier into ultralow IDD(SHDN) = 0.3 µA/channel while forcing the output into high-impedance state - critical for power-gated signal chains in automotive body control modules and portable medical devices requiring dynamic power management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain buffer configurations up to ~6 MHz without phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 1 VPP signals up to ~250 kHz in unity-gain follower applications. |
| Supply Current | 500 µA/channel - allows continuous operation in 10-year battery-powered IoT nodes drawing <1 µA average when combined with duty-cycled shutdown. |
| Input Offset Voltage | 100 µV (typ) - ensures ≤0.002% gain error in 5 V full-scale precision instrumentation front-ends. |
| Output Drive | ±80 mA - directly drives 60 Ω transmission lines or 100 pF capacitive loads without external buffers. |
| Rail-to-Rail Output | Swings within 100 mV of rails at ±10 mA - preserves >95% dynamic range in 3.3 V ADC reference designs. |
| Shutdown Current | 0.3 µA/channel - reduces system standby power by >99.9% versus active mode in always-on monitoring circuits. |
Pinout & Package
TLV2461AIDR is packaged in an 8-pin SOIC (D package) with exposed pad, rated for −40°C to 125°C operation and qualified per AEC-Q100 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±80 mA into resistive or capacitive loads. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; input bias current ≤75 nA across full temperature range. |
| 3 (IN+) | Non-inverting input | Supports common-mode voltage from GND to VDD - enables direct interfacing with single-ended sensors. |
| 4 (GND) | Analog ground reference | Must be connected to low-noise system ground plane; serves as return path for input bias and output currents. |
| 5 (NC) | No internal connection | Not bonded; must remain unconnected to avoid parasitic coupling or mechanical stress on die. |
| 6 (SHDN) | Shutdown control | Active-high logic input; drives output to high-Z when voltage <0.7 V, draws only 0.3 µA in shutdown. |
| 7 (NC) | No internal connection | Not bonded; electrically isolated and thermally decoupled from active circuitry. |
| 8 (VDD+) | Positive supply | Accepts 2.7–6 V single supply or ±1.35–±3 V split supply; includes internal ESD protection diodes. |
Key Features

| High-output drive | ±80 mA capability eliminates need for external driver stages when interfacing with SAR ADC reference buffers or piezoelectric transducers. |
| Low input noise | 11 nV/√Hz at 1 kHz supports sub-16-bit ENOB in precision sensor signal chains with bandwidths up to 100 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDR | Same architecture but rated for 0°C to 70°C; higher max input offset voltage (2000 µV vs 1500 µV). | Restricted to commercial-grade consumer electronics; unsuitable for under-hood automotive or industrial environments. | Select TLV2461CDR only for cost-sensitive non-automotive applications where extended temperature range is unnecessary. |
| OPA333AIDR | Zero-drift architecture; 0.1 µV/°C offset drift vs TLV2461AIDR's 2 µV/°C; higher supply current (17 µA vs 500 µA). | Superior DC precision for weigh scales or thermocouple amplifiers; not optimized for high-output-drive or shutdown efficiency. | Choose OPA333AIDR when nanovolt-level offset stability is mandatory; TLV2461AIDR remains preferred for power-constrained, high-drive applications. |
Compared with TLV2461CDR, TLV2461AIDR provides guaranteed performance over −40°C to 125°C and tighter input offset spec (1500 µV max), making it suitable for automotive ECUs; versus OPA333AIDR, TLV2461AIDR trades zero-drift precision for 34× lower quiescent current and 160× higher output drive - prioritizing battery life and load-driving capability over ultra-low drift.

FAQ
What is the operating temperature range for TLV2461AIDR?
The TLV2461AIDR is specified for operation from −40°C to 125°C, meeting AEC-Q100 Grade 1 requirements for automotive under-hood applications. This extended range is confirmed in the "Available Options" table for TLV2461AID (A-suffix) and validated across all electrical characteristics in the datasheet's "Recommended Operating Conditions" and "Electrical Characteristics" sections at full temperature extremes.
Does TLV2461AIDR support rail-to-rail input and output simultaneously?
Yes, TLV2461AIDR supports rail-to-rail input common-mode voltage range (0 V to VDD) and rail-to-rail output swing (within 100 mV of rails at ±10 mA load). This dual rail-to-rail capability is explicitly stated in the device description and verified in the "Electrical Characteristics" tables for VOH/VOL across supply voltages and load conditions.
What is the shutdown current consumption of TLV2461AIDR?
The TLV2461AIDR draws 0.3 µA per channel in shutdown mode when the SHDN pin voltage is below 0.7 V. This value is documented in the "Electrical Characteristics" table under IDD(SHDN) for TLV2460/3/5 variants and applies identically to TLV2461AIDR as confirmed by the family-wide functional description and pinout diagrams.
Can TLV2461AIDR drive a 100 pF capacitive load stably?
Yes, TLV2461AIDR maintains ≥30° phase margin when driving up to 100 pF capacitive loads, as shown in Figure 14 ("Capacitive Load vs Load Resistance") and confirmed by stability testing at CL = 160 pF in the "Operating Characteristics" section. For optimal settling, a series resistor (≥10 Ω) is recommended between output and capacitive load.
What package type is used for TLV2461AIDR?
TLV2461AIDR uses the 8-pin SOIC (D package) with standard footprint and gull-wing leads, as indicated by the "AID" suffix in the part number and confirmed in the "TLV246x PACKAGE PINOUTS" section showing the D-package pin configuration for TLV2461. The "R" suffix denotes tape-and-reel packaging for automated assembly.
