Product details
Overview
TLV2461QPWRG4 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 input offset voltage, and 11 nV/√Hz input noise voltage - enabling accurate buffering of analog-to-digital converters in 2.7–6 V supply applications.
For engineers reviewing the TLV2461QPWRG4 datasheet, TLV2461QPWRG4 pinout, TLV2461QPWRG4 application, or TLV2461QPWRG4 equivalent, this device supports Q-temp automotive qualification (−40°C to 125°C), features micropower shutdown (0.3 µA/channel), and provides rail-to-rail dynamic range critical for low-voltage sensor interfaces and data acquisition front-ends.
Technical Context
The TLV2461QPWRG4 employs a CMOS input stage with rail-to-rail common-mode input voltage range (0 V to VDD) and rail-to-rail output swing, eliminating headroom loss in single-supply systems. Its 6.4 MHz unity-gain bandwidth and 1.6 V/µs slew rate are achieved at only 500 µA supply current per channel, balancing ac performance and power efficiency.
It integrates a dedicated shutdown terminal (SHDN) that places the amplifier in ultralow-current mode (0.3 µA/channel) while forcing the output into high-impedance state - supporting power-gating in battery-operated or thermally constrained designs without external isolation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - enables stable unity-gain operation up to ~6 MHz with minimal phase margin degradation. |
| Slew Rate | 1.6 V/µs - supports clean 10-bit ADC sampling at ≥100 kSPS for full-scale 2 VPP signals. |
| Input Offset Voltage | 100 µV - ensures ≤0.004% gain error in precision 12-bit sensor signal chains at room temperature. |
| Supply Current | 500 µA/channel - allows continuous operation in always-on subsystems with <1 mW total dissipation at 3 V. |
| Output Drive | ±80 mA - directly drives 50 Ω transmission lines or 10 kΩ loads with <100 mV droop at full swing. |
| Input Noise Voltage | 11 nV/√Hz @ 1 kHz - preserves SNR in low-level transducer amplification (e.g., bridge sensors, thermocouples). |
| Shutdown Current | 0.3 µA/channel - reduces standby power by >99.9% versus active mode, critical for duty-cycled monitoring nodes. |
Pinout & Package
TSSOP-8 package (PW suffix), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, qualified for automotive temperature range (−40°C to 125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±80 mA into resistive loads. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; differential input resistance >10⁹ Ω supports high-Z sensor interfaces. |
| 3 (IN+) | Non-inverting input | Accepts common-mode voltages from 0 V to VDD - eliminates level-shifting in single-supply configurations. |
| 4 (GND) | Analog ground reference | Primary return path for input bias currents and output load current; must be low-impedance for noise control. |
| 5 (NC) | No internal connection | Unbonded pin; no electrical function - must remain unconnected or grounded per layout best practices. |
| 6 (SHDN) | Shutdown control input | Active-high logic: VIH ≥ 2 V enables operation; VIL ≤ 0.7 V forces 0.3 µA shutdown state and high-Z output. |
| 7 (VDD+) | Positive supply | Supports 2.7–6 V single supply or ±1.35–±3 V split supply; internal regulation ensures stable bias over voltage range. |
| 8 (NC) | No internal connection | Unbonded pin; no electrical function - must remain unconnected or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 2.7–6 V supply range - maximizes dynamic range in low-voltage ADC drivers without external level shifters. |
| Micropower shutdown | Reduces quiescent current to 0.3 µA/channel while maintaining high-Z output - essential for intermittent-sampling sensor nodes. |
| Automotive Q-temp qualification | Rated for −40°C to 125°C operation with AEC-Q100 stress testing - suitable for engine control, ADAS, and body electronics. |
| Low input offset drift | 2 µV/°C temperature coefficient - limits offset drift to <160 µV across full automotive temperature range. |
| High output drive capability | ±80 mA output current - eliminates need for external buffer stages when driving capacitive loads or low-impedance networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IP | Same core specs but in PDIP-8 package; higher θJA (104°C/W); no automotive qualification. | Limited to commercial/industrial ambient (0°C to 70°C); unsuitable for under-hood or chassis-mounted use. | Select only for lab prototypes or non-automotive cost-sensitive designs where through-hole assembly is required. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV offset, 0.02 µV/°C drift; 360 µA supply current; no shutdown pin. | Superior dc precision but lacks integrated shutdown; lower bandwidth (350 kHz) limits ac response. | Choose when ultra-low offset/drift dominates requirements and power gating is handled externally or not needed. |
Compared with TLV2461QPWRG4, TLV2461IP offers identical functionality in legacy through-hole form but lacks automotive temperature rating and thermal performance, while OPA333AIDBVR trades bandwidth and integrated shutdown for nanovolt-level dc precision - making TLV2461QPWRG4 optimal for automotive signal chains requiring balanced ac/dc performance and power control.

FAQ
What is the operating temperature range for TLV2461QPWRG4?
The TLV2461QPWRG4 is qualified for the automotive temperature range of −40°C to +125°C, meeting Q-temp requirements for under-hood and chassis-mounted electronics. This rating is confirmed in the TI datasheet SLOS220J revision February 2004, under Recommended Operating Conditions and Package Options tables for Q-suffix devices in PW package.
Does TLV2461QPWRG4 support true rail-to-rail input and output operation?
Yes, TLV2461QPWRG4 supports rail-to-rail input (common-mode range = 0 V to VDD) and rail-to-rail output (swing within 10 mV of rails at 10 mA load). This is explicitly stated in the device description and verified in Electrical Characteristics tables for VOH/VOL at VDD = 3 V and 5 V across full temperature range.
What is the shutdown behavior of TLV2461QPWRG4?
When SHDN is pulled ≤0.7 V, TLV2461QPWRG4 enters shutdown mode drawing 0.3 µA/channel and placing the output in high-impedance state. The turnoff time is 328 ns (typical), and the output remains disconnected from both rails - confirmed in Operating Characteristics and Absolute Maximum Ratings sections of SLOS220J.
Is TLV2461QPWRG4 pin-compatible with other TLV246x variants?
No - TLV2461QPWRG4 (TSSOP-8) has different pinout than TLV2460 (SOT-23-6) or TLV2462 (SOIC-8). Among TSSOP-8 variants, TLV2461QPWRG4 matches TLV2461IP and TLV2461CDR pin-for-pin, but differs from TLV2463/2464/2465 due to channel count and shutdown configuration - per Pinouts section in SLOS220J.
What are the key differences between TLV2461QPWRG4 and TLV2461CDR?
TLV2461QPWRG4 uses Q-temp automotive qualification (−40°C to 125°C), TSSOP-8 (PW) package, and G4 suffix indicating green/RoHS compliance. TLV2461CDR is commercial-grade (0°C to 70°C), same PW package, but lacks automotive stress testing and extended temperature validation - detailed in the Available Options tables of SLOS220J.
