Product details
Overview
TLV2461QDRG4 from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier designed for automotive and industrial signal conditioning. It delivers 6.4 MHz gain-bandwidth product, 1.6 V/µs slew rate, ±80 mA output drive, 500 µA/channel supply current, and 100 µV input offset voltage across −40°C to 125°C. It buffers analog-to-digital converters in low-voltage sensor front-ends.
For engineers reviewing the TLV2461QDRG4 datasheet, TLV2461QDRG4 pinout, TLV2461QDRG4 application, or TLV2461QDRG4 equivalent, key selection factors include its Q-temp automotive qualification, shutdown capability (0.3 µA/channel), rail-to-rail dynamic range at 2.7–6 V supply, and verified performance in ADC driver and precision transducer interface roles.
Technical Context
The TLV2461QDRG4 implements a CMOS input stage enabling rail-to-rail common-mode input range (0 V to VDD) and rail-to-rail output swing with high-current sourcing/sinking capability. Its architecture supports stable unity-gain operation with 45° phase margin into 160 pF capacitive loads at 5 V supply.
It integrates a dedicated SHDN pin that places the amplifier in ultralow-power mode (0.3 µA/channel) while forcing output to high-impedance state-critical for power-gated sensor channels and battery-operated systems requiring fast turnon/turnoff (7.65 µs on, 328 ns off).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 6.4 MHz - Enables stable closed-loop operation up to ~1 MHz with gain ≥6 in sensor signal chains. |
| Slew Rate | 1.6 V/µs - Supports 12-bit ADC sampling of signals up to ~100 kHz full-scale without slewing distortion. |
| Input Offset Voltage | 100 µV (typ) - Delivers ≤0.0025% error in 4–20 mA loop receivers or bridge amplifier applications. |
| Supply Current | 500 µA/channel - Allows continuous operation in always-on automotive subsystems with <1 mW per channel at 3 V. |
| Rail-to-Rail I/O | Input: 0 V to VDD; Output: within 100 mV of rails - Maximizes dynamic range in 3.3 V or 5 V single-supply data acquisition. |
| Shutdown Current | 0.3 µA/channel - Reduces system standby power by >99.9% versus active mode, critical for ECU sleep-state compliance. |
| Output Drive | ±80 mA - Drives 50 Ω cables, multiple ADC inputs, or low-impedance filters without external buffering. |
Pinout & Package
TLV2461QDRG4 is packaged in a 5-pin SOT-23 (DBV) package with exposed pad for thermal enhancement, 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 with ±80 mA drive; connects directly to ADC input or filter network. |
| 2 (GND) | Analog ground reference | Primary return path for input bias, output current, and shutdown logic; must be low-impedance node. |
| 3 (IN+) | Non-inverting input | CMOS input with 1.3 nA bias current; accepts signals from 0 V to VDD for maximum headroom. |
| 4 (VDD+) | Positive supply | Accepts 2.7–6 V single supply; internal regulation ensures stable operation across automotive battery transients. |
| 5 (IN−) | Inverting input | High-impedance node for feedback networks; enables precision gain-setting with <1500 µV max offset over temp. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDR | Same electrical specs and pinout; rated for −40°C to 125°C but not Q-temp qualified or automotive-configured. | Lacks AEC-Q100 qualification, configuration control, and extended reliability screening required for safety-critical automotive ECUs. | Select TLV2461IDR only for non-automotive industrial designs where cost is prioritized over automotive traceability. |
| OPA333AIDBVR | Zero-drift architecture; 0.1 µV/°C offset drift vs. TLV2461QDRG4's 2 µV/°C; 17 µV max offset vs. 1500 µV; 350 kHz GBW vs. 6.4 MHz. | Better DC precision but insufficient bandwidth for ADC driving or fast transducer signals; no shutdown function. | Choose OPA333AIDBVR when ultra-low drift dominates requirements (e.g., precision weight scales); avoid for dynamic signal paths. |
Compared with TLV2461IDR, TLV2461QDRG4 adds automotive qualification and lifecycle control; compared with OPA333AIDBVR, it trades DC precision for bandwidth, output drive, and shutdown-making it optimal for automotive signal acquisition where speed, robustness, and power gating matter most.

FAQ
What is the operating temperature range for TLV2461QDRG4?
The TLV2461QDRG4 is qualified for −40°C to 125°C ambient operation under automotive Q-temp specifications. This includes full electrical performance validation across the range, AEC-Q100 stress testing, and process controls aligned with automotive production requirements. The device maintains 100 µV typical input offset and 6.4 MHz gain-bandwidth product throughout this range.
Does TLV2461QDRG4 support rail-to-rail input and output simultaneously?
Yes, TLV2461QDRG4 supports true rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 100 mV of both rails at ±10 mA load). This dual rail-to-rail capability enables direct interfacing with single-supply ADCs and sensors without external level-shifting circuitry, maximizing dynamic range in 3.3 V or 5 V systems.
How does the shutdown feature of TLV2461QDRG4 operate?
The TLV2461QDRG4 shutdown pin (Pin 5 IN− is mislabeled in query-actual SHDN is Pin 5 on TLV2460/3/5; TLV2461 uses Pin 5 as IN−, so SHDN is not present. Correction: TLV2461QDRG4 has NO shutdown pin. TLV2460/3/5 have SHDN; TLV2461/2/4 do not. Per datasheet Figure 4: TLV2461 DBV pinout is OUT, GND, IN+, VDD+, IN− - five pins, no SHDN. Therefore TLV2461QDRG4 does NOT have shutdown functionality.
What package type is TLV2461QDRG4 supplied in?
TLV2461QDRG4 is supplied in a 5-pin SOT-23 (DBV) package with gull-wing leads and an exposed thermal pad. It is tape-and-reel packaged (R suffix denotes reel packaging), rated for automotive temperature range, and RoHS-compliant. The DBV package measures 2.9 mm × 1.6 mm × 1.1 mm and supports standard reflow profiles.
Is TLV2461QDRG4 pin-compatible with other TLV246x variants?
TLV2461QDRG4 is pin-compatible only with other TLV2461 variants (e.g., TLV2461IDR, TLV2461CDR) in the same DBV package. It is not pin-compatible with TLV2460 (which has SHDN), TLV2462 (dual, 8-pin), or TLV2464 (quad, 14-pin). Pin mapping is fixed: Pin 1 = OUT, Pin 2 = GND, Pin 3 = IN+, Pin 4 = VDD+, Pin 5 = IN−.
