Product details
Overview
TLV2442QDG4 from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for automotive-grade operation across –40°C to 125°C. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 950 µV max input offset voltage at 25°C, and rail-to-rail output swing into 600-Ω loads-enabling high-fidelity signal conditioning in low-voltage sensor interfaces and ADC drivers.
For engineers reviewing the TLV2442QDG4 datasheet, TLV2442QDG4 pinout, TLV2442QDG4 application, or TLV2442QDG4 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.25 V min at 5-V supply), no phase inversion behavior, 16 nV/√Hz input voltage noise at 1 kHz, and Q-temp qualification for automotive systems requiring AEC-Q100 alignment.
Technical Context
The TLV2442QDG4 uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>1 TΩ), making it suitable for interfacing with high-impedance sources like piezoelectric transducers and pH electrodes. Its rail-to-rail output stage supports full dynamic range utilization in single-supply 2.7–10 V systems.
It features no phase inversion when common-mode input reaches either supply rail, eliminating output glitches in precision instrumentation. The device is fully characterized at both 3-V and 5-V supplies, with guaranteed performance over temperature and qualified to automotive reliability standards including AEC-Q100.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442AIDR | Same core specs but in SOIC-8 (D) package with I-temp grade (–40°C to +85°C); 950 µV VIO max at 25°C | Rated for industrial, not automotive temperature range; lacks AEC-Q100 qualification | Select when automotive qualification is unnecessary and cost sensitivity favors standard industrial grade |
| OPA2333AIDR | Zero-drift architecture; 12 µV max VIO, 0.1 µV/°C drift; higher 350 µA/channel supply current | Superior DC precision but lower bandwidth (350 kHz) and no guaranteed 600-Ω drive | Select for ultra-low-offset applications where long-term stability outweighs speed and output drive needs |
Compared with TLV2442AIDR, TLV2442QDG4 adds AEC-Q100 qualification and extended temperature support; compared with OPA2333AIDR, it trades zero-drift precision for higher bandwidth, stronger output drive, and lower cost in automotive signal chains.

FAQ
What is the operating temperature range for TLV2442QDG4?
The TLV2442QDG4 is qualified for operation from –40°C to +125°C and meets AEC-Q100 Grade 1 requirements. This range is explicitly defined in the "Recommended Operating Conditions" table of the SLOS169H datasheet and confirmed by its Q-suffix designation, making TLV2442QDG4 suitable for under-hood automotive applications and industrial environments with extreme thermal cycling.
Does TLV2442QDG4 support true rail-to-rail input operation?
No, TLV2442QDG4 provides rail-to-rail *output* swing only. Its common-mode input voltage range extends to VDD– and up to VDD+–1.3 V at 125°C (or VDD+–1 V at 85°C), meaning it accepts inputs down to ground but not fully to the positive rail. This is clearly specified in the "Recommended Operating Conditions" table for Q-suffix devices, distinguishing TLV2442QDG4 from true rail-to-rail input amplifiers.
Can TLV2442QDG4 drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, TLV2442QDG4 is explicitly characterized to drive 600-Ω loads with rail-to-rail output swing. Figure 10 in the SLOS169H datasheet shows VOH ≥4 V and VOL ≤1.25 V at ±5 mA into 600 Ω with 5-V supply and TA = 25°C. Performance remains functional across temperature, with VOL ≤1 V and VOH ≥4 V at 125°C per the "Electrical Characteristics" tables - confirming TLV2442QDG4's suitability for telecom and ADC interface applications.
What is the maximum supply voltage rating for TLV2442QDG4?
The absolute maximum supply voltage for TLV2442QDG4 is 12 V, as stated in the "Absolute Maximum Ratings" table. However, the recommended operating range is 2.7 V to 10 V. Operation above 10 V is not guaranteed for parametric performance and risks violating safe operating area limits, especially at elevated temperatures. All electrical characteristics in the datasheet are validated within the 2.7–10 V range.
Is TLV2442QDG4 pin-compatible with other members of the TLV244x family?
Yes, TLV2442QDG4 shares identical pinout and footprint with all TLV2442 variants in the SOIC-8 (D) package, including TLV2442CDR, TLV2442AIDR, and TLV2442IDR. The pin configuration - OUT A, IN– A, IN+ A, GND, IN+ B, IN– B, OUT B, VDD+ - is standardized across the dual-channel TLV2442 family, enabling drop-in replacement within the same package variant, provided temperature and offset specifications align with system requirements.
