Product details
Overview
TLV2442QDGKRQ1 from Texas Instruments is a dual-channel, rail-to-rail output automotive-grade operational amplifier optimized for low-voltage (2.7 V to 10 V) operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 16 nV/√Hz input voltage noise at 1 kHz, 600-Ω output drive capability, and operates across –40°C to 125°C - enabling precision signal conditioning in battery-powered ADAS sensor interfaces.
For engineers reviewing the TLV2442QDGKRQ1 datasheet, TLV2442QDGKRQ1 pinout, TLV2442QDGKRQ1 application, or TLV2442QDGKRQ1 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.25 V min at 5 V), no phase inversion behavior near rails, low 950 µV max input offset voltage (TLV2442A-Q1 variant), and AEC-Q100 qualification for automotive powertrain and body electronics.
Technical Context
This device uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>1 TΩ differential and common-mode resistance), ultra-low input bias current (1 pA typ), and stable operation into 600-Ω loads. Its architecture avoids phase inversion when common-mode inputs reach either supply rail - eliminating need for external clamping in single-supply transducer front-ends.
The TLV2442QDGKRQ1 is fully characterized at 3 V and 5 V supplies, with guaranteed performance over temperature (–40°C to 125°C). It supports unity-gain stable operation with 100 pF capacitive load and provides 65° phase margin at 3 V, making it suitable for driving ADC reference buffers and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use with Li-ion, 3.3 V, and 5 V systems without LDOs. |
| Gain-Bandwidth Product | 1.8 MHz (typ at 5 V) - supports closed-loop bandwidth up to ~0.9 MHz at gain = 2 for sensor amplification. |
| Input Offset Voltage | 950 µV max (TLV2442A-Q1 grade) - ensures <0.1% error in 1 V full-scale 12-bit ADC interfacing. |
| Output Drive Capability | ±3 mA into 600 Ω (VOH/VOL ≤1.25 V / ≥0.8 V at 5 V) - directly drives telecom line drivers and SAR ADC references. |
| Input Voltage Noise | 16 nV/√Hz (typ at 1 kHz, 5 V) - preserves SNR in low-level piezoelectric or thermopile signal chains. |
| Common-Mode Input Range | 0 V to 4.25 V min (at 5 V supply) - accepts ground-referenced signals without level-shifting. |
| Quiescent Current | 750 µA per channel (typ) - enables always-on monitoring in automotive wake-up circuits. |
Pinout & Package
TLV2442QDGKRQ1 is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. Pin 1 is marked by a dot; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance node (1 TΩ) for feedback network connection; sensitive to PCB leakage at <1 pA bias. |
| 2 | Non-Inverting Input (Channel 1) | Accepts common-mode voltages down to VDD– (GND); no phase inversion up to rail. |
| 3 | Output (Channel 1) | Rail-to-rail swing (0.02 V to 4.97 V at 5 V, IO = ±100 µA); drives 600 Ω loads directly. |
| 4 | Ground / Negative Supply | Shared return path for both channels; requires low-impedance local decoupling (0.1 µF + 1 µF). |
| 5 | Positive Supply | Accepts 2.7–10 V; internal ESD protection >2 kV HBM ensures robustness in assembly. |
| 6 | Non-Inverting Input (Channel 2) | Independent of Channel 1; identical CMVR and offset specs enable matched dual-sensor buffering. |
| 7 | Inverting Input (Channel 2) | Matched input bias current (<150 pA max) minimizes offset drift in differential configurations. |
| 8 | Output (Channel 2) | Same AC performance as Pin 3; supports independent gain stages or parallel drive for higher current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of both rails at light load - maximizes dynamic range for 12-bit+ ADCs. |
| No phase inversion | Operates linearly even when IN+ or IN– exceeds supply rails - eliminates need for input clamps. |
| Extended common-mode input range | 0 V to VDD–1 V minimum - accepts true ground-referenced signals in single-supply systems. |
| Low input bias current (1 pA typ) | Enables high-Z sensor interfacing (e.g., pH electrodes, photodiodes) without significant DC error. |
| AEC-Q100 Grade 1 qualified | Validated for automotive applications from –40°C to 125°C ambient - suitable for engine bay sensors. |
| 600-Ω output drive | Directly drives telecom line interface ICs and SAR ADC reference inputs without buffer stages. |

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 package (TSSOP-8), but tighter 950 µV max VIO spec and 2 µV/°C tempco vs. 2.5 mV max for TLV2442QDGKRQ1. | Preferred for precision analog front-ends requiring <0.1% gain error stability over temperature. | Select when offset drift budget is critical; otherwise TLV2442QDGKRQ1 offers cost advantage for general-purpose use. |
| LM7332QMA/NOPB | Higher slew rate (10 V/µs), wider supply (2.7–32 V), but higher quiescent current (2.5 mA/ch) and no AEC-Q100 Grade 1 rating. | Suitable for industrial 24 V systems, not qualified for automotive underhood environments. | Choose only if higher speed or wider supply range outweighs automotive qualification and power constraints. |
Compared with TLV2442AQPWRQ1, TLV2442QDGKRQ1 trades tighter offset specs for lower cost and MSOP packaging; compared with LM7332QMA/NOPB, it delivers automotive qualification and 3× lower supply current at the expense of bandwidth and voltage range.

FAQ
What is the maximum operating temperature for TLV2442QDGKRQ1?
The TLV2442QDGKRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This specification is validated across all electrical parameters in the datasheet, including input offset voltage, common-mode rejection ratio, and output drive capability - ensuring reliability in under-hood automotive environments.
Does TLV2442QDGKRQ1 support rail-to-rail input?
No, TLV2442QDGKRQ1 features rail-to-rail *output* only. Its common-mode input voltage range extends from VDD– (GND) to VDD–1 V minimum (e.g., 0 V to 4.25 V at 5 V supply), which exceeds typical CMOS op-amps but does not include the positive rail. Input phase inversion is avoided up to the rails, but full rail-to-rail input requires separate devices like the TLV9062-Q1.
Can TLV2442QDGKRQ1 drive a 600-Ω load effectively?
Yes, TLV2442QDGKRQ1 is explicitly specified to drive 600-Ω loads: at 5 V supply, VOH ≥4 V and VOL ≤1.25 V with ±3 mA output current. This capability is verified across temperature (–40°C to 125°C) and enables direct interfacing with telecom line drivers, SAR ADC references, and active filter stages without external buffers.
What is the input offset voltage specification for TLV2442QDGKRQ1?
The TLV2442QDGKRQ1 has a maximum input offset voltage of 2.5 mV at TA = 25°C (full-range max not specified in provided data). This differs from the TLV2442A-Q1 variant (950 µV max), and reflects its position as the standard-grade automotive version - suitable for applications where moderate DC accuracy suffices, such as non-precision sensor buffering or comparator hysteresis generation.
Is TLV2442QDGKRQ1 pin-compatible with other TLV244x-Q1 variants?
Yes, TLV2442QDGKRQ1 shares identical 8-pin MSOP (DGK) pinout with TLV2442A-Q1 variants (e.g., TLV2442AQDGKRQ1), as confirmed by TI's package drawings and functional block diagrams. All TLV2442-x variants use the same pin mapping: Pins 1–3 and 6–8 for Channel 1 and Channel 2 I/O, Pin 4 for GND, and Pin 5 for VDD+.
