Product details
Overview
TLV2442QDRQ1 from Texas Instruments is a dual-channel automotive-grade rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V) operation, featuring 1.8 MHz gain-bandwidth product, 750 µA per channel supply current, 16 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing - enabling high-fidelity signal conditioning in battery-powered automotive sensor interfaces and ADC drivers.
For engineers reviewing the TLV2442QDRQ1 datasheet, TLV2442QDRQ1 pinout, TLV2442QDRQ1 application, or TLV2442QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, extended common-mode input range (0 V to 4.25 V min at 5 V), 950 µV max input offset voltage (TLV2442A-Q1 variant), and 600-Ω output drive capability for telecom and data acquisition systems.
Technical Context
The TLV2442QDRQ1 employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion when inputs approach supply rails, supporting robust operation in single-supply configurations. Its input stage delivers ultra-low input bias current (1 pA typ) and high input impedance (>1 TΩ), making it suitable for high-impedance source interfacing like piezoelectric sensors.
It features internal compensation for stable unity-gain operation with 600-Ω loads and 100 pF capacitive loads, delivering 0.75–1.4 V/µs slew rate (5 V supply), 65°–68° phase margin, and 0.4–1.3 V/mV large-signal voltage amplification across –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide automotive battery and LDO-regulated rails without external level-shifting. |
| Gain-Bandwidth Product | 1.8 MHz (typ at 5 V) - enables stable closed-loop operation up to ~100 kHz with moderate gain for sensor amplification. |
| Input Offset Voltage | 950 µV max (TLV2442A-Q1 spec; TLV2442QDRQ1 is standard grade, 2.5 mV max) - defines DC accuracy in precision buffer and summing applications. |
| Output Drive Capability | ±3 mA into 600 Ω (VOH/VOL ≤1.25 V / ≥0.8 V at 5 V) - ensures full rail-to-rail swing into telecom line-driver and DAC output buffers. |
| Input Voltage Noise | 16 nV/√Hz (typ at 1 kHz, 5 V) - critical for low-noise amplification of microvolt-level signals from thermocouples or strain gauges. |
| Common-Mode Input Range | 0 V to 4.25 V (min at 5 V supply) - allows direct sensing of ground-referenced signals without level-shifting circuitry. |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and powertrain control modules. |
Pinout & Package
TLV2442QDRQ1 is housed in an 8-pin SOIC (D) package with exposed pad not present; thermal performance rated at 725 mW (TA ≤25°C), derating to 145 mW at 125°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance differential input node; accepts signals within 0 V to VDD–1 V common-mode range. |
| 2 | Non-Inverting Input (Channel 1) | High-impedance differential input node; supports rail-to-rail common-mode operation without phase reversal. |
| 3 | Output (Channel 1) | Rail-to-rail output capable of sourcing/sinking ±3 mA into 600 Ω while maintaining <1.25 V VOL / >4 V VOH at 5 V. |
| 4 | Ground / VDD– | Reference return path for both channels; must be low-impedance to minimize PSRR degradation and noise coupling. |
| 5 | Non-Inverting Input (Channel 2) | Independent high-Z input for second channel; identical CMVR and bias specs as Pin 2. |
| 6 | Inverting Input (Channel 2) | Independent high-Z input for second channel; matches Pin 1 electrical behavior and layout sensitivity. |
| 7 | Output (Channel 2) | Second rail-to-rail output; electrically isolated from Channel 1 but shares same supply and thermal path. |
| 8 | Positive Supply (VDD+) | Primary power rail; supplies both amplifiers; requires local 0.1 µF ceramic decoupling adjacent to Pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of both rails at 5 V with 600-Ω load - maximizes dynamic range for 12-bit+ ADC interfacing. |
| No phase inversion on rail inputs | Operates linearly even when IN+ or IN– reaches VDD or GND - eliminates latch-up risk in overvoltage transients. |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-value feedback networks (>1 MΩ) used in precision integrators and photodiode amps. |
| AEC-Q100 Grade 1 qualified | Validated for automotive use from –40°C to +125°C ambient with HTOL, TC, ESD (2 kV HBM), and EMC robustness testing. |
| Extended common-mode input range | Accepts inputs down to GND and up to VDD–1 V - enables direct interface with 0–5 V industrial sensors and microcontroller I/O. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442AQPWRQ1 | Same architecture, but guaranteed 950 µV max input offset voltage (vs. 2.5 mV for TLV2442QDRQ1); TSSOP-8 package. | Required where DC accuracy dominates over cost; e.g., precision current sensing or calibration circuits. | Select TLV2442AQPWRQ1 when VIO budget is <1 mV; note different package (PW) and reel size (2000). |
| LM7332QMA/NOPB | Higher slew rate (10 V/µs), wider supply (2.7–36 V), but higher supply current (2.5 mA/ch) and no AEC-Q100 Grade 1 rating. | Suitable for high-speed industrial controls but not qualified for automotive powertrain or safety-critical domains. | Choose LM7332QMA/NOPB only for non-automotive applications needing faster response; TLV2442QDRQ1 remains preferred for AEC-Q100 compliance. |
Compared with TLV2442AQPWRQ1, TLV2442QDRQ1 trades guaranteed low offset for lower cost and SOIC packaging; versus LM7332QMA/NOPB, it offers automotive qualification and micropower operation at the expense of bandwidth and voltage range.

FAQ
What is the maximum input common-mode voltage range for TLV2442QDRQ1 at 5 V supply?
At VDD = 5 V, the TLV2442QDRQ1 supports a common-mode input voltage range of 0 V to 4.25 V (minimum specification). This allows direct interfacing with ground-referenced sensors and microcontroller outputs without level-shifting circuitry, and is validated across the full –40°C to +125°C operating temperature range.
Is TLV2442QDRQ1 pin-compatible with TLV2442AQPWRQ1?
No, TLV2442QDRQ1 (SOIC-8, D package) is not pin-compatible with TLV2442AQPWRQ1 (TSSOP-8, PW package). While both share identical pin functions and ordering logic, their physical footprints differ - SOIC-8 has 1.27 mm pitch and 6.0 mm width, whereas TSSOP-8 has 0.65 mm pitch and 3.0 mm width. PCB redesign is required for substitution.
Does TLV2442QDRQ1 support single-supply operation with rail-to-rail input?
TLV2442QDRQ1 provides rail-to-rail *output* swing but does *not* feature rail-to-rail *input*. Its common-mode input range extends from VDD– to VDD–1 V (e.g., 0 V to 4 V at 5 V supply), meaning it accepts inputs down to ground but not fully to VDD. For true rail-to-rail input, consider TI's TLV9062-Q1 or OPA333-Q1.
What is the typical supply current per channel for TLV2442QDRQ1 at 3 V operation?
The TLV2442QDRQ1 draws 750 µA per channel (typical) at VDD = 3 V and TA = 25°C, with a maximum of 1100 µA per channel across the full –40°C to +125°C temperature range. This micropower consumption enables use in always-on automotive modules and battery-backed industrial sensors.
Can TLV2442QDRQ1 drive a 100 pF capacitive load stably?
Yes, TLV2442QDRQ1 is internally compensated for unity-gain stability with capacitive loads up to 100 pF when driving a 600-Ω resistive load (per datasheet Figure 18–19). Phase margin remains ≥65° at 25°C, ensuring monotonic step response without ringing in ADC driver and filter applications.
