Product details
Overview
TLV2442QPW from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for automotive-grade operation (–40°C to +125°C), featuring 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, 750 µA per channel supply current, and 600-Ω output drive capability. It operates from 2.7 V to 10 V supplies and delivers full rail-to-rail output swing with extended common-mode input range (0 V to 4.25 V min at 5 V), making it suitable for precision signal conditioning in automotive sensor interfaces and low-voltage data acquisition systems.
For engineers reviewing the TLV2442QPW datasheet, TLV2442QPW pinout, TLV2442QPW application, or TLV2442QPW equivalent, key selection criteria include its AEC-Q100 qualified Q-temp automotive rating, guaranteed 950 µV VIO max over temperature, no phase inversion behavior, and compatibility with single-supply ADC driver topologies requiring wide dynamic range and low noise (16 nV/√Hz typ at 1 kHz).
Technical Context
The TLV2442QPW uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ differential and common-mode resistance), ultra-low input bias current (1 pA typ), and rail-to-rail output stage capable of sourcing/sinking ±5 mA while maintaining linearity into 600-Ω loads. Its architecture avoids phase inversion when common-mode inputs reach either supply rail - a critical advantage over standard CMOS op-amps in high-gain, single-supply configurations.
It is fully characterized across –40°C to +125°C, supports 3-V and 5-V operation, and exhibits stable unity-gain performance with 65° phase margin (RL = 600 Ω, CL = 100 pF). The device's low 0.9 MHz maximum output-swing bandwidth at 1-Vpp and 0.75 V/µs slew rate (5 V supply) reflect its balanced trade-off between speed, power, and precision for battery-constrained automotive subsystems.
Key Specifications

|---|---|
| Supply Voltage Range | 2.7 V to 10 V - Enables direct interface with 3.3 V and 5 V automotive microcontrollers without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - Ensures ≤0.02% gain error in 2.5 V full-scale 12-bit ADC front-ends. |

Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad optional; RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail voltage with ±5 mA drive; connects directly to ADC input or transducer load. |
| 2 (IN–1) | Channel 1 inverting input | High-impedance node (1 TΩ); requires matched trace routing to minimize offset drift from leakage. |
| 3 (IN+1) | Channel 1 non-inverting input | Accepts common-mode voltages from VDD– to VDD+ – 1.3 V; immune to phase reversal at rails. |
| 4 (GND / VDD–) | Power return / negative rail | Shared ground reference for both channels; must be low-inductance connection to avoid crosstalk. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent high-Z input; enables dual-channel sensor conditioning (e.g., differential thermocouple + RTD). |
| 6 (IN–2) | Channel 2 inverting input | Matched to Pin 2; supports precision instrumentation amplifier configurations with external resistors. |
| 7 (OUT2) | Channel 2 output | Electrically isolated output stage; allows independent loading without interaction with OUT1. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor (100 nF ceramic) required within 3 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extends to both supply rails without output polarity reversal - eliminates need for input clamping diodes in rail-referenced sensors. |
| Extended common-mode range | 0 V to 4.25 V (min) at 5 V supply - accommodates 0–5 V industrial analog inputs without attenuation or level shift. |
| Low input noise | 16 nV/√Hz at 1 kHz - preserves SNR in low-level microphone preamps and strain gauge amplifiers. |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C) - meets reliability requirements for under-hood and chassis-mounted electronics. |
| Macromodel included | SPICE model provided by TI - enables accurate simulation of settling time, THD+N, and stability margins before PCB spin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442AIPW | Same specs but rated for –40°C to +85°C industrial temp range; 950 µV VIO max only at 25°C (not over full range). | Not qualified for under-hood automotive use; lacks AEC-Q100 certification and extended high-temp validation. | Select TLV2442AIPW only for cost-sensitive industrial designs where ambient temperature stays below 85°C. |
| OPA2333QPWR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2442QPW's 2 µV/°C; higher 350 µA/channel supply current. | Better long-term DC stability for precision weigh scales; less suitable for wideband sensor excitation due to lower 350 kHz GBW. | Choose OPA2333QPWR when microvolt-level offset stability over time and temperature outweighs bandwidth and power requirements. |
Compared with TLV2442AIPW, the TLV2442QPW provides guaranteed 950 µV VIO across –40°C to +125°C and AEC-Q100 qualification, while the OPA2333QPWR trades bandwidth and power for near-zero drift - making TLV2442QPW optimal for cost-constrained, high-temperature automotive signal chains needing 1.8 MHz bandwidth.

FAQ
What is the maximum operating temperature range for the TLV2442QPW?
The TLV2442QPW is rated for continuous operation from –40°C to +125°C and is AEC-Q100 qualified for automotive applications. This specification is validated across the full range, including guaranteed 950 µV max input offset voltage at 25°C and functional performance up to 125°C ambient - critical for engine control, transmission, and ADAS subsystems.
Does the TLV2442QPW support true rail-to-rail input operation?
No, the TLV2442QPW features rail-to-rail *output* swing only. Its common-mode input voltage range extends from VDD– to VDD+ – 1.3 V (at 5 V supply), reaching 0 V to 4.25 V minimum - sufficient for most single-supply applications but not full rail-to-rail input. Input phase inversion is eliminated, however, even when driven to the rails.
Can the TLV2442QPW drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, the TLV2442QPW is explicitly characterized to drive 600-Ω loads with rail-to-rail output swing: at 5 V supply, VOH ≥ 4.0 V and VOL ≤ 0.8 V with 5 mA load current. This capability is confirmed in the datasheet's Figure 10 and electrical characteristics tables, enabling direct interfacing with telecom line drivers and SAR ADC reference buffers.
Is the TLV2442QPW pin-compatible with other devices in the TLV244x family?
Yes, all TLV244x dual op-amps in TSSOP-8 (PW) package - including TLV2442CD, TLV2442AID, TLV2442AIPW, and TLV2442QPW - share identical pinouts. This allows drop-in replacement across temperature grades and offset specifications without PCB layout changes, provided the system's thermal and qualification requirements align with the selected variant.
What SPICE model is available for simulating the TLV2442QPW?
Texas Instruments provides a validated PSpice macromodel for the TLV2442QPW, downloadable from ti.com. The model accurately replicates key behaviors including input offset voltage distribution, slew rate limiting, rail-to-rail output saturation, and stability margins with 600-Ω loads and 100-pF capacitive loads - essential for verifying settling time and THD+N before hardware prototyping.
