Product details
Overview
TLV2461AQPWRG4Q1 from Texas Instruments is a single-channel, automotive-grade rail-to-rail input/output operational amplifier with shutdown functionality, 6.4 MHz gain-bandwidth product, 1.6 V/μs slew rate, ±80-mA output drive, and 500 μA/channel supply current. It operates from 2.7 V to 6 V and is designed for precision analog signal conditioning in battery management systems and lighting modules.
For engineers reviewing the TLV2461AQPWRG4Q1 datasheet, TLV2461AQPWRG4Q1 pinout, TLV2461AQPWRG4Q1 application, or TLV2461AQPWRG4Q1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), rail-to-rail output swing, 100 μV typical input offset voltage, 11 nV/√Hz input noise voltage, and TSSOP-8 package compatibility with space-constrained automotive PCB layouts.
Technical Context
The TLV2461AQPWRG4Q1 implements a CMOS input stage enabling rail-to-rail common-mode input range (–0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 10 mV of each rail at ±10 mA load. Its internal architecture supports stable unity-gain operation with 45° phase margin into 160 pF capacitive loads.
Shutdown mode reduces supply current to 0.3 μA per channel while placing the output in high-impedance state-enabling power-gating in multi-amplifier sensor front-ends. The device maintains 90 dB minimum CMRR and 85 dB minimum PSRR across –40°C to +125°C, supporting robust performance in noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 6.4 MHz - enables stable closed-loop operation up to ~100 kHz with gain ≥ 64, suitable for anti-aliasing and active filtering in ADC driver stages. |
| Slew rate | 1.6 V/μs - supports 100-kHz full-power bandwidth for 1-Vpp signals, sufficient for fast transient response in motor current sensing. |
| Supply current per channel | 500 μA - enables ultra-low-power operation in always-on vehicle subsystems such as door module wake-up circuits. |
| Input offset voltage | 150 μV (max, full temp range) - ensures ≤ 0.15% error in 100-mV full-scale current shunt measurements over automotive temperature range. |
| Output drive capability | ±80 mA - drives 50-Ω transmission lines or directly interfaces with SAR ADC reference buffers without external gain staging. |
| Rail-to-rail I/O | Input extends 0.2 V beyond rails; output swings within 10 mV of rails at ±10 mA - maximizes dynamic range in 3.3-V or 5-V single-supply systems. |
| Shutdown current | 0.3 μA - allows selective channel disablement in multi-sensor nodes to reduce system standby power below 1 μA. |
Pinout & Package
TSSOP-8 (PW) package, 4.40 mm × 3.00 mm body size, 0.65-mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output terminal; high-impedance during shutdown; capable of sourcing/sinking ±80 mA. |
| 2 | IN− | Inverting input; CMVR extends to –0.2 V and VDD + 0.2 V; input bias current 1.3 nA (typ, 5 V). |
| 3 | IN+ | Noninverting input; matched to IN− for low input offset; differential input resistance >10⁹ Ω. |
| 4 | GND | Negative supply reference; must be low-impedance return path for output current and shutdown logic. |
| 5 | NC | No internal connection; electrically isolated; may be left floating or tied to GND for mechanical stability. |
| 6 | SHDN | Active-low shutdown control; <0.7 V disables amplifier (0.3 μA IDD); >2 V enables normal operation. |
| 7 | VDD+ | Positive supply input; supports 2.7 V to 6 V; total supply current scales linearly with VDD. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461QPWRQ1 | Higher input offset voltage (2000 μV max vs. 1500 μV max for TLV2461AQPWRG4Q1); same GBW, slew rate, and shutdown behavior. | Less suitable for sub-1-mV precision current sensing; acceptable for general-purpose buffering where offset is trimmed digitally. | Select TLV2461QPWRQ1 only if cost sensitivity outweighs offset-critical performance; verify calibration overhead in BMS firmware. |
| LMV931QDBVRQ1 | Lower GBW (1.5 MHz), lower output drive (±45 mA), no shutdown pin; AEC-Q100 Grade 1 qualified, same TSSOP-8 package. | Not viable for high-speed signal chains or high-current loads; limited to low-frequency sensor interfaces with relaxed bandwidth needs. | Choose LMV931QDBVRQ1 only for cost-optimized designs where 1.5-MHz bandwidth suffices and shutdown is implemented externally. |
Compared with TLV2461QPWRQ1 and LMV931QDBVRQ1, the TLV2461AQPWRG4Q1 delivers superior precision (lower VIO), higher dynamic performance (6.4 MHz vs. 1.5 MHz), and integrated power gating-making it the optimal choice for next-generation automotive sensor signal chains requiring both accuracy and configurability.

FAQ
What is the operating temperature range for TLV2461AQPWRG4Q1?
The TLV2461AQPWRG4Q1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current, making it suitable for under-hood and cabin-mounted automotive ECUs without derating.
Does TLV2461AQPWRG4Q1 support single-supply operation?
Yes, TLV2461AQPWRG4Q1 supports true single-supply operation from 2.7 V to 6 V. Its rail-to-rail input stage accepts common-mode voltages from –0.2 V to VDD + 0.2 V, and its output swings within 10 mV of both rails at ±10 mA, enabling direct interface with 3.3-V or 5-V microcontrollers and ADCs without level-shifting circuitry.
How does the shutdown function behave on TLV2461AQPWRG4Q1?
Applying <0.7 V to the SHDN pin places TLV2461AQPWRG4Q1 in ultra-low-power shutdown mode, reducing supply current to 0.3 μA per channel. During shutdown, the output enters high-impedance state-preventing loading of downstream circuits. The amplifier resumes full operation within 7.6 μs after SHDN rises above 2 V.
What is the maximum capacitive load TLV2461AQPWRG4Q1 can drive stably?
TLV2461AQPWRG4Q1 maintains stability with up to 160 pF capacitive load at unity gain, as verified by 45° phase margin in the datasheet. For loads exceeding 100 pF, TI recommends adding a 10-Ω series resistor between the output and capacitor to isolate reactive feedback and preserve phase margin in ADC driver or cable-driving configurations.
Is TLV2461AQPWRG4Q1 pin-compatible with other devices in the TLV246x-Q1 family?
TLV2461AQPWRG4Q1 shares identical TSSOP-8 pinout with TLV2461QPWRQ1 and TLV2461AQPWRQ1, including IN−, IN+, OUT, GND, NC, SHDN, VDD+, and NC assignments. However, it is not pin-compatible with dual (TLV2462x-Q1) or quad (TLV2464A-Q1) variants due to differing channel count and pin functions-board layout reuse is limited to single-channel variants only.
