Product details
Overview
TLV2442AQPW 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 precision signal conditioning in low-voltage sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2442AQPW datasheet, TLV2442AQPW pinout, TLV2442AQPW application, or TLV2442AQPW equivalent, this device is selected for high-impedance source amplification, battery-powered sensing, and single-supply analog front-ends where phase inversion immunity and extended common-mode input range (0 V to 4.25 V at 5 V supply) are critical.
Technical Context
The TLV2442AQPW uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ), high input impedance (>1 TΩ), and no phase inversion when common-mode voltage reaches either rail. Its architecture supports stable unity-gain operation with 600-Ω load drive capability and maintains >65° phase margin at 1 MHz with 100 pF capacitive load.
It is fully characterized at 3 V and 5 V supplies, with guaranteed performance over automotive temperature range (–40°C to +125°C), including 50 dB CMRR and 80 dB SVR across full operating range - making it suitable for harsh-environment signal chains requiring long-term offset stability and noise resilience.
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 level-shifting. |
| Input Offset Voltage (max) | 950 µV at 25°C - ensures <0.02% error in 5 V full-scale precision measurement paths. |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - supports stable closed-loop gain up to ~10× at 100 kHz for sensor amplification. |
| Slew Rate | 0.75 V/µs at 5 V - sufficient for 10-bit ADC driving at 100 kSPS with <0.1% settling error. |
| Input Bias Current | 1 pA typ - preserves signal integrity in piezoelectric, pH, or photodiode transducer interfaces. |
| Output Drive | 600-Ω load compatible - directly drives telecom line drivers and SAR ADC reference buffers without external buffering. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V supply - accepts ground-referenced sensors and rail-sensing configurations. |

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 |
|---|---|---|---|
| TLV2442IPW | Same pinout and architecture, but rated for –40°C to +85°C industrial range; 2.5 mV max VIO vs. 950 µV. | Not qualified for automotive AEC-Q100; unsuitable for under-hood or cabin control modules. | Select TLV2442IPW only for cost-sensitive industrial designs where extended temperature and precision are not required. |
| OPA2333AIPW | Zero-drift architecture; 10 µV max VIO, 0.02 µV/°C drift, but higher 17 µA supply current and 350 kHz GBW. | Better DC precision but lower bandwidth; less suitable for fast-sampling sensor interfaces above 50 kHz. | Choose OPA2333AIPW when nanovolt-level offset stability dominates over power and speed constraints. |
Compared with TLV2442IPW, the TLV2442AQPW provides tighter offset and automotive qualification; versus OPA2333AIPW, it trades zero-drift precision for lower power and higher bandwidth - making it optimal for cost-constrained, battery-aware automotive signal chains demanding robustness and speed.

FAQ
What is the maximum operating temperature range for the TLV2442AQPW?
The TLV2442AQPW is qualified for continuous operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive applications. This rating is confirmed in the Absolute Maximum Ratings table and Operating Conditions section of the SLOS169H datasheet, with full electrical characterization across the entire range.
Does the TLV2442AQPW support true rail-to-rail input operation?
No - the TLV2442AQPW features rail-to-rail *output* but has an extended common-mode input voltage range (0 V to 4.25 V min at 5 V supply), not full rail-to-rail input. It does not accept inputs beyond VDD– or VDD+, unlike dedicated rail-to-rail input op-amps such as the OPA333.
Can the TLV2442AQPW drive a 100-pF capacitive load stably?
Yes - the TLV2442AQPW maintains >65° phase margin with 100 pF capacitive load and 600 Ω series resistance at unity gain, as verified in Figure 19 and the Operating Characteristics table. This makes it suitable for driving ADC inputs and long PCB traces without external isolation resistors.
What is the typical supply current per channel for TLV2442AQPW at 3 V supply?
The typical supply current per channel for TLV2442AQPW is 725 µA at 3 V and 25°C, with a maximum of 1100 µA across the full temperature range. This value is specified in the Electrical Characteristics table under IDD (Supply current per channel) for VDD = 3 V.
Is the TLV2442AQPW pin-compatible with other members of the TLV244x family?
Yes - all TLV244x dual op-amps in TSSOP-8 (PW) package, including TLV2442CD, TLV2442ID, and TLV2442AIPW, share identical pinout and footprint. The TLV2442AQPW maintains full mechanical and electrical compatibility, differing only in temperature grade and input offset specification.
