Product details
Overview
TLV2461QDRG4Q1 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 used in HEV/EV battery management systems for precision signal conditioning of cell voltage and temperature sensors.
For engineers reviewing the TLV2461QDRG4Q1 datasheet, TLV2461QDRG4Q1 pinout, TLV2461QDRG4Q1 application, or TLV2461QDRG4Q1 equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, AEC-Q100 Grade 1 qualification (–40°C to +125°C), shutdown current of 0.3 μA/channel, input offset voltage ≤2000 μV, and TSSOP-8 package compatibility with space-constrained automotive modules.
Technical Context
The TLV2461QDRG4Q1 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 100 mV of each rail under 10-mA load. Its internal architecture supports stable operation with capacitive loads up to 160 pF and delivers 11 nV/√Hz input noise voltage at 1 kHz.
Shutdown control is active-low (SHDN < 0.7 V), placing the output in high-impedance state while reducing supply current to 0.3 μA/channel. The device maintains 60 dB minimum CMRR and 75 dB minimum PSRR across –40°C to +125°C, meeting functional safety requirements for ASIL-B–relevant analog front-ends.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461A-Q1 | Lower input offset voltage (150 μV typ vs. 100 μV typ for TLV2461-Q1); same pinout, package, and specs otherwise | Better DC accuracy for precision voltage monitoring where offset drift dominates error budget | Select TLV2461A-Q1 when input offset voltage ≤1500 μV over temperature is mandatory; TLV2461QDRG4Q1 remains optimal for cost-sensitive designs meeting 2000 μV limit |
| LMV931QDBVRQ1 | Lower supply current (120 μA vs. 500 μA), lower GBW (1.5 MHz), no shutdown pin, SOT-23-6 package | Targeted at ultra-low-power always-on sensors where bandwidth <100 kHz suffices and PCB area is constrained | Choose LMV931QDBVRQ1 only if shutdown function is unnecessary and layout cannot accommodate TSSOP-8; TLV2461QDRG4Q1 provides superior drive strength and flexibility |

FAQ
What is the maximum operating supply voltage for TLV2461QDRG4Q1?
The absolute maximum supply voltage for TLV2461QDRG4Q1 is 6 V. Operation above this voltage risks permanent damage. The recommended operating range is 2.7 V to 6 V, with stable rail-to-rail performance verified across this span. At 6 V, output swing remains within 100 mV of both rails under 10-mA load, and input common-mode range extends to –0.2 V to 6.2 V.
Does TLV2461QDRG4Q1 support true rail-to-rail input and output operation?
Yes, TLV2461QDRG4Q1 supports true rail-to-rail input and output operation. Its CMOS input stage allows common-mode voltage range from –0.2 V to VDD + 0.2 V, exceeding supply rails. Output swings to within 100 mV of VDD+ and GND under 10-mA load, and to within 30 mV under 2.5-mA load-verified per Electrical Characteristics tables at both 3 V and 5 V supplies.
What is the shutdown behavior of TLV2461QDRG4Q1?
When SHDN is pulled low (<0.7 V), TLV2461QDRG4Q1 enters ultra-low-power shutdown mode drawing 0.3 μA/channel. During shutdown, the output is placed in high-impedance state-no pull-up or pull-down-ensuring safe isolation from downstream circuitry. Turn-on time is 7.6 μs, and turn-off time is 333 ns, enabling rapid wake/sleep cycling in battery-monitoring applications.
Is TLV2461QDRG4Q1 qualified for automotive applications?
Yes, TLV2461QDRG4Q1 is AEC-Q100 qualified for automotive use. It meets Grade 1 requirements: ambient operating temperature from –40°C to +125°C, HBM ESD classification Level 2 (±2000 V), and CDM Level C6 (±1000 V). It also exceeds MIL-STD-883 Method 3015 ESD rating (2000 V) and machine model (200 V), ensuring reliability in assembly and field environments.
What package type is used for TLV2461QDRG4Q1?
TLV2461QDRG4Q1 uses an 8-pin TSSOP package (PW suffix), with nominal body dimensions of 4.40 mm × 3.00 mm. This surface-mount package features gull-wing leads, is RoHS-compliant, and has moisture sensitivity level 1-requiring no dry-pack handling. Pinout matches industry-standard single op-amp TSSOP layouts, enabling drop-in replacement in existing designs using compatible footprints.
