Product details
Overview
TLV2442QPWRQ1 from Texas Instruments is a dual-channel, automotive-qualified rail-to-rail output operational amplifier with 1.8 MHz gain-bandwidth product, 750 µA per channel supply current, and 16 nV/√Hz input voltage noise at 1 kHz. It operates from 2.7 V to 10 V, delivers ±3 mA output drive into 600 Ω, and supports common-mode input range from VDD– to (VDD+ – 1) V - enabling precision signal conditioning in battery-powered automotive sensor interfaces.
For engineers reviewing the TLV2442QPWRQ1 datasheet, TLV2442QPWRQ1 pinout, TLV2442QPWRQ1 application, or TLV2442QPWRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 950 µV max input offset voltage (TLV2442A variant), rail-to-rail output swing, low 1 pA typical input bias current, and robust 600-Ω load drive capability for ADC buffering and transducer amplification.
Technical Context
The TLV2442QPWRQ1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion when inputs approach supply rails - eliminating need for costly rail-to-rail input op-amps in many designs. Its architecture supports stable operation with 600 Ω loads and 100 pF capacitive loads, delivering 65° phase margin at unity gain.
It features low-noise (16 nV/√Hz), low-offset (950 µV max), and low-power (750 µA/ch) operation optimized for 3 V and 5 V single-supply systems. The device is fully characterized across –40°C to 125°C and includes ESD protection exceeding 2 kV (MIL-STD-883) and 200 V (machine model).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use in 3.3 V and 5 V automotive domains without LDO regulation. |
| Gain-Bandwidth Product | 1.8 MHz (typ) - supports stable closed-loop gain up to ~100× at 10 kHz for sensor signal amplification. |
| Input Offset Voltage | 950 µV max (TLV2442A-Q1 variant) - ensures ≤0.5% error in 0.5 V full-scale differential sensor outputs. |
| Output Drive Capability | ±3 mA into 600 Ω - drives standard telecom and ADC reference buffers without external gain stages. |
| Input Voltage Noise | 16 nV/√Hz at 1 kHz - preserves SNR in high-impedance piezoelectric or thermopile sensor front-ends. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V supply - accepts signals from ground-referenced sensors up to near-rail levels. |
| Quiescent Current | 750 µA per channel (typ) - enables dual-opamp functionality in <1.5 mW total power budget for body control modules. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not present, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback or inverted signal path; high impedance (1 TΩ) minimizes loading on high-Z sources. |
| 2 | Non-inverting input (Channel 1) | Reference or sensor input node; common-mode range extends to both rails for ground-sensed signals. |
| 3 | Output (Channel 1) | Rail-to-rail swing (within 10 mV of rails at light load) enables full dynamic range into ADCs. |
| 4 | Ground / VDD− | Return path for dual-supply operation or system ground in single-supply configurations. |
| 5 | Positive supply / VDD+ | Primary power connection; supports 2.7–10 V; internal ESD protection clamps to rails. |
| 6 | Non-inverting input (Channel 2) | Independent second channel input; identical specs to Channel 1 for dual-sensor or differential pair use. |
| 7 | Inverting input (Channel 2) | Second channel inverting node; matched offset and bias current enable precision instrumentation topologies. |
| 8 | Output (Channel 2) | Second rail-to-rail output; capable of independent loading up to 600 Ω without stability degradation. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Inputs driven to either supply rail do not cause output polarity reversal - eliminates latch-up risk in overvoltage sensor conditions. |
| Rail-to-rail output | Swings within 10 mV of VDD+ and VDD− at 100 µA load - maximizes usable ADC input range in 3.3 V systems. |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to 125°C) with PPAP support - qualified for engine control, HVAC, and ADAS subsystems. |
| Low input bias current | 1 pA typical - prevents significant voltage drop across >100 MΩ source impedances (e.g., pH electrodes, pyroelectric sensors). |
| 600-Ω output drive | Stable 3 mA sourcing/sinking into 600 Ω - directly interfaces with legacy telecom line drivers and SAR ADC reference buffers. |
Applications
| Automotive Cabin Temperature Sensing | Body Control Module Current Monitoring |

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 |
|---|---|---|---|
| LM7332QMA/NOPB | Higher supply current (2.1 mA/ch), wider supply range (±2.5 V to ±16 V), no AEC-Q100 Grade 1 rating. | Preferred for industrial dual-supply systems requiring higher output voltage swing; not qualified for automotive under-hood use. | Select LM7332QMA/NOPB only if dual-supply operation or >10 V output compliance is required; verify qualification status per OEM requirement. |
| TSV912IQ2T | Lower input offset (1.5 mV max), lower noise (23 nV/√Hz), AEC-Q100 Grade 0 (–40°C to 150°C), but only 1.6 MHz GBW. | Better suited for ultra-low-power body electronics where 150°C operation is mandatory; less suitable for high-fidelity sensor bandwidth. | Choose TSV912IQ2T for extended temperature zones (e.g., powertrain proximity); confirm 1.6 MHz GBW meets signal bandwidth requirements. |
Compared with LM7332QMA/NOPB and TSV912IQ2T, the TLV2442QPWRQ1 uniquely balances AEC-Q100 Grade 1 qualification, 1.8 MHz bandwidth, 16 nV/√Hz noise, and 750 µA/ch quiescent current - making it optimal for cost-sensitive, thermally demanding cabin and chassis control nodes.

FAQ
What is the operating temperature range for the TLV2442QPWRQ1?
The TLV2442QPWRQ1 is qualified for automotive use with an operating free-air temperature range of –40°C to 125°C (AEC-Q100 Grade 1). All electrical specifications - including input offset voltage, supply current, and gain-bandwidth product - are guaranteed across this full range, enabling deployment in engine bay, cabin, and chassis control modules without derating.
Does the TLV2442QPWRQ1 support rail-to-rail input operation?
No, the TLV2442QPWRQ1 features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from VDD– to (VDD+ – 1) V - for example, 0 V to 4.25 V minimum at 5 V supply. This allows ground-referenced inputs but does not accept signals at the positive rail; for true rail-to-rail input, consider TI's TLV9002-Q1.
What is the maximum capacitive load the TLV2442QPWRQ1 can drive stably?
The TLV2442QPWRQ1 is characterized for stable operation with up to 100 pF capacitive load when driving a 600 Ω resistor, achieving 65° phase margin at unity gain. Driving larger capacitive loads (e.g., >200 pF) requires isolation resistance or careful compensation; consult Figure 18–20 in the SGLS181C datasheet for frequency-domain stability data.
Is the TLV2442QPWRQ1 pin-compatible with other devices in the TLV244x-Q1 family?
Yes, the TLV2442QPWRQ1 shares identical TSSOP-8 pinout with TLV2442AQPWRQ1 and TLV2442QDRQ1 (SOIC-8 variant differs). All TLV2442-x variants use the same pin configuration: pins 1–3 and 6–8 for Channel 1/2 I/O, pin 4 as GND/VDD−, and pin 5 as VDD+. This enables direct substitution between TLV2442QPWRQ1 and TLV2442AQPWRQ1 in existing layouts.
How does the input offset voltage of TLV2442QPWRQ1 compare to TLV2442AQPWRQ1?
The TLV2442QPWRQ1 has a maximum input offset voltage of 2.5 mV at 25°C, while the TLV2442AQPWRQ1 is binned to 950 µV max. Both share identical temperature coefficient (2 µV/°C) and long-term drift (0.002 µV/month). For precision applications requiring <1 mV offset, specify TLV2442AQPWRQ1; for cost-optimized general-purpose use, TLV2442QPWRQ1 provides sufficient accuracy.
