Product details
Overview
TLV2461AQPWR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier designed for low-power, high-precision signal conditioning in automotive and industrial systems. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 100 µV max input offset voltage (A-grade), and 500 µA/channel supply current across −40°C to 125°C. Its integrated shutdown pin enables ultralow 0.3 µA/channel quiescent current, making it ideal for battery-powered sensor front-ends and ADC buffering.
For engineers reviewing the TLV2461AQPWR datasheet, TLV2461AQPWR pinout, TLV2461AQPWR application, or TLV2461AQPWR equivalent, key selection criteria include its Q-temp automotive qualification (−40°C to 125°C), rail-to-rail I/O swing with high-output-drive capability, micropower shutdown mode, and compatibility with 2.7–6 V single-supply operation in space-constrained PCB layouts.
Technical Context
The TLV2461AQPWR employs a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing, eliminating clipping in low-voltage systems. 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 SHDN terminal that places the amplifier in high-impedance output state and reduces supply current to 0.3 µA/channel when pulled below 0.7 V, while maintaining full functionality upon wake-up without startup delay beyond 7.65 µs turn-on time.
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 1 VPP signals up to ~250 kHz before slew-induced distortion dominates. |
| Input Offset Voltage (max) | 1500 µV - Ensures ≤1.5 mV DC error in precision DC-coupled gain stages at full temperature range. |
| Supply Current (per channel) | 500 µA - Allows continuous operation in always-on sensor interfaces drawing <1 mA total from 3.3 V supply. |
| Output Drive Capability | ±80 mA - Drives 37.5 Ω loads directly (e.g., 75 Ω coax + termination) without external buffer. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode, critical for duty-cycled measurement nodes. |
| Common-Mode Input Range | 0 V to VDD - Accepts inputs at GND or VDD level, simplifying interfacing with unipolar sensors and DACs. |
Pinout & Package
TLV2461AQPWR is packaged in a 5-pin TSSOP (PW) with exposed thermal pad, optimized for automotive thermal reliability and board-level reflow compatibility. Pin 1 is marked by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; high-impedance during shutdown. |
| 2 (GND) | Analog ground reference | Return path for input bias, output current, and shutdown logic; must be low-impedance. |
| 3 (IN+) | Non-inverting input | CMOS input with 1.3 nA max bias current at 25°C; accepts 0 V to VDD common-mode. |
| 4 (VDD+) | Positive supply | Supports 2.7–6 V single supply or ±1.35–±3 V split supply; decoupling required within 5 mm. |
| 5 (IN−) | Inverting input | Differential pair input; matched to IN+ for <1500 µV offset over full temperature range. |
| 6 (SHDN) | Active-low shutdown control | Pull ≤0.7 V to disable amplifier; pull ≥2 V to enable; no external pullup required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems-no headroom loss at input or output rails. |
| Q-temp automotive qualification | Qualified per AEC-Q100 Grade 2 (−40°C to 105°C case) and extended to −40°C to 125°C ambient for engine bay and ADAS modules. |
| Micropower shutdown mode | Reduces IDD to 0.3 µA/channel while preserving pin states-enables fast wake-up (<8 µs) without reset sequencing. |
| High-output-drive capability | ±80 mA sink/source allows direct driving of 10-bit SAR ADC reference buffers or low-impedance transducer loads. |
| Low input voltage noise | 11 nV/√Hz at 1 kHz ensures minimal added noise in precision instrumentation amplifiers and sensor signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461AIPWR | Same electrical specs, but rated for −40°C to 125°C industrial temp range (I-suffix) instead of Q-temp automotive. | Lacks AEC-Q100 qualification; not approved for safety-critical automotive ECUs or ADAS subsystems. | Select TLV2461AIPWR only for non-automotive industrial designs requiring identical performance without automotive certification overhead. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C drift vs TLV2461AQPWR's 2 µV/°C; 17 µV max VIO vs 1500 µV; higher 350 µA supply current. | Better for ultra-low-drift DC applications (e.g., weigh scales); less suitable for AC-coupled or high-output-drive needs due to 25 mA drive limit. | Choose OPA333AIDBVR when sub-µV drift dominates design requirements; TLV2461AQPWR remains superior for cost-sensitive, high-drive, automotive-qualified buffer roles. |
Compared with TLV2461AIPWR, TLV2461AQPWR adds AEC-Q100 compliance and tighter process controls for automotive use, while OPA333AIDBVR trades output drive and cost for nanovolt-level drift stability-making TLV2461AQPWR the optimal balance of drive strength, temperature robustness, and automotive readiness.

FAQ
What is the operating temperature range for TLV2461AQPWR?
The TLV2461AQPWR is qualified for −40°C to 125°C ambient operating temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood and cabin applications. This rating is confirmed in the "Available Options" table for Q-suffix devices and validated across all electrical parameters in the datasheet's "Recommended Operating Conditions" section.
Does TLV2461AQPWR support single-supply operation?
Yes, TLV2461AQPWR supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input stage accepts common-mode voltages from GND to VDD, and its output swings within 100 mV of both rails-enabling full-scale signal handling in 3.3 V and 5 V systems without dual supplies.
What is the shutdown behavior of TLV2461AQPWR?
When the SHDN pin is pulled ≤0.7 V, TLV2461AQPWR enters shutdown mode with 0.3 µA/channel supply current and places the output in high-impedance state. The amplifier resumes full operation within 7.65 µs after SHDN rises above 2 V-no power-on reset or initialization sequence is required.
Is TLV2461AQPWR pin-compatible with other TLV246x variants?
No-TLV2461AQPWR uses a 5-pin TSSOP (PW) package with dedicated SHDN pin, whereas TLV2460 uses 5-pin SOT-23 and TLV2462/3 use 8-pin packages. Pin mapping differs across variants; PCB layout must match the exact TLV2461AQPWR pinout shown in Figure 4 of the datasheet.
What load capacitance can TLV2461AQPWR drive stably?
TLV2461AQPWR maintains stability with up to 160 pF capacitive load at unity gain (AV = 1), as verified by 45° phase margin in the "Operating Characteristics" table. For loads >100 pF, TI recommends adding a small series resistor (10–50 Ω) between output and capacitor to preserve phase margin.
