Product details
Overview
TLV2442AQDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier qualified for automotive applications (AEC-Q100 Grade 1), featuring 1.8 MHz gain-bandwidth product, 750 µA per channel supply current at 5 V, 950 µV max input offset voltage at 25°C, and 600-Ω output drive capability - used in precision sensor signal conditioning and ADC interface circuits in vehicle control modules.
For engineers reviewing the TLV2442AQDRQ1 datasheet, TLV2442AQDRQ1 pinout, TLV2442AQDRQ1 application, or TLV2442AQDRQ1 equivalent, key selection considerations include its extended common-mode input range (0 V to 4.25 V min at 5-V supply), low 16 nV/√Hz input noise at 1 kHz, no phase inversion behavior, and guaranteed operation from –40°C to 125°C.
Technical Context
The TLV2442AQDRQ1 employs Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>1 TΩ common-mode and differential resistance) and ultra-low input bias current (1 pA typ). Its architecture avoids phase inversion when inputs approach supply rails, enabling robust performance in single-supply configurations without external level-shifting.
It delivers 600-Ω load drive with ±3 mA output current capability at 5 V, supports stable operation with 100 pF capacitive loads (65° phase margin), and features low 1.4 V/µs slew rate optimized for precision, low-noise, low-power applications - not high-speed signal chain use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct operation from 3.3 V or 5 V automotive rails without regulation. |
| Input Offset Voltage (Max) | 950 µV at 25°C - ensures <1 LSB error in 12-bit ADC interfacing at 5 V full-scale. |
| Gain-Bandwidth Product | 1.8 MHz (typ at 5 V) - supports closed-loop bandwidth up to ~170 kHz with unity-gain stability on 600-Ω loads. |
| Supply Current per Channel | 750 µA (typ at 5 V) - enables dual op-amp operation within 1.5 mA total, suitable for always-on vehicle subsystems. |
| Common-Mode Input Range | 0 V to 4.25 V (min at 5 V) - allows direct sensing of ground-referenced signals without level shifters. |
| Output Drive Capability | ±3 mA into 600 Ω - sustains rail-to-rail swing under moderate load, critical for driving SAR ADC reference buffers. |
| Input Noise Voltage | 16 nV/√Hz (typ at 1 kHz, 5 V) - preserves SNR in low-level piezoelectric or thermistor signal chains. |
Pinout & Package
TLV2442AQDRQ1 is housed in an 8-pin SOIC (D package), 3.91 mm × 4.9 mm body, 1.75 mm height, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot.
| 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 current. |
| 2 | Non-Inverting Input (Channel 1) | Accepts common-mode voltages from VDD– to VDD+ – 1 V; no phase inversion up to rails. |
| 3 | Output (Channel 1) | Rail-to-rail capable (0.01 V to 4.97 V at 5 V); drives 600 Ω directly; requires local 100 nF bypass at VDD+. |
| 4 | VDD– / Ground | Power return for both channels; must be low-impedance path to minimize PSRR degradation. |
| 5 | VDD+ | Positive supply input (2.7–10 V); decoupling required within 5 mm of pin for stability with capacitive loads. |
| 6 | Non-Inverting Input (Channel 2) | Independent high-Z input; identical specs to Pin 2; supports dual-sensor front-end architectures. |
| 7 | Inverting Input (Channel 2) | Matches Pin 1 electrical behavior; layout symmetry recommended for matched gain accuracy. |
| 8 | Output (Channel 2) | Functionally identical to Pin 3; enables independent signal paths (e.g., sensor + reference buffer). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 10 mV of both supply rails at 5 V, maximizing dynamic range for 12-bit+ ADCs. |
| No phase inversion | Operates linearly with inputs driven to VDD– or VDD+, eliminating latch-up risk in overvoltage transients. |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to 125°C) with PPAP-ready manufacturing and 100% final test screening. |
| Low input bias current | 1 pA typical enables high-impedance source interfacing (e.g., pH electrodes, photodiodes) without guard traces. |
| Extended common-mode range | 0 V to 4.25 V min at 5 V supply allows direct connection to ground-referenced sensors without level shifters. |
| Low noise & drift | 16 nV/√Hz @ 1 kHz and 2 µV/°C tempco support precision DC-coupled measurement over temperature. |

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 |
|---|---|---|---|
| TLV2442QDRQ1 | Higher 2.5 mV max input offset voltage (vs. 950 µV for TLV2442AQDRQ1); otherwise identical specs and pinout. | Suitable for cost-sensitive non-precision functions (e.g., LED dimming control) where <12-bit accuracy is acceptable. | Select TLV2442QDRQ1 only if VIO >1.5 mV is tolerable; TLV2442AQDRQ1 required for <0.5°C thermal sensing or 12-bit ADC linearity. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C), lower 5.5 µV max VIO, but higher 17 µA supply current and no AEC-Q100 qualification. | Used in lab-grade instrumentation; lacks automotive reliability testing, qualification, and PPAP documentation. | OPA2333AIDR offers superior DC precision but cannot replace TLV2442AQDRQ1 in production automotive ECUs without requalification. |
Compared with TLV2442QDRQ1, TLV2442AQDRQ1 provides tighter input offset for high-accuracy sensing; compared with OPA2333AIDR, it trades ultra-low drift for AEC-Q100 compliance and 23× lower quiescent current - essential for always-on vehicle subsystems.

FAQ
What is the maximum operating temperature for TLV2442AQDRQ1?
The TLV2442AQDRQ1 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, CMRR, and output drive capability, with no derating needed up to 125°C.
Does TLV2442AQDRQ1 support rail-to-rail input?
No, TLV2442AQDRQ1 does not support rail-to-rail input - its common-mode input voltage range is specified as 0 V to VDD+ – 1 V (min 4.25 V at 5 V supply). However, it does provide true rail-to-rail output swing and exhibits no phase inversion when inputs reach either supply rail.
Can TLV2442AQDRQ1 drive a 100 pF capacitive load stably?
Yes, TLV2442AQDRQ1 maintains 65° phase margin with 100 pF capacitive load at unity gain (RL = 600 Ω), as confirmed in Figure 19 of the datasheet. Stability is ensured when using proper 100 nF local VDD+ bypassing and minimizing trace inductance between output and load.
What is the input bias current specification for TLV2442AQDRQ1?
The TLV2442AQDRQ1 has a typical input bias current of 1 pA at 25°C, with a maximum of 260 pA across the full –40°C to 125°C temperature range. This ultra-low value enables accurate amplification of signals from high-impedance sources such as piezoelectric sensors or pH electrodes without significant error.
Is TLV2442AQDRQ1 pin-compatible with TLV2442QDRQ1?
Yes, TLV2442AQDRQ1 and TLV2442QDRQ1 share identical SOIC-8 (D package) pinout, footprint, and electrical interface. The only functional difference is the tighter 950 µV max input offset voltage specification for TLV2442AQDRQ1 versus 2.5 mV for TLV2442QDRQ1 - both are drop-in replacements in hardware layout.
