Product details
Overview
TLV2442AQPWRG4Q1 from Texas Instruments is a dual-channel automotive-grade rail-to-rail output operational amplifier with 1.8 MHz gain-bandwidth, 750 µA per channel supply current, and 950 µV max input offset voltage at 25°C. It operates from 2.7 V to 10 V, delivers ±3 mA into 600 Ω loads, and supports extended common-mode input range (0 V to 4.25 V min at 5 V), enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2442AQPWRG4Q1 datasheet, TLV2442AQPWRG4Q1 pinout, TLV2442AQPWRG4Q1 application, or TLV2442AQPWRG4Q1 equivalent, key selection criteria include its AEC-Q100 qualification, low 16 nV/√Hz noise at 1 kHz, no phase inversion behavior, 600-Ω output drive capability, and guaranteed performance across –40°C to 125°C.
Technical Context
The TLV2442AQPWRG4Q1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>1 TΩ differential and common-mode resistance) and ultra-low input bias current (1 pA typ). Its architecture eliminates phase inversion when inputs approach either supply rail, supporting robust operation in wide-input-voltage-range applications.
It features a unity-gain-stable design optimized for capacitive loads up to 100 pF with 65° phase margin (RL = 600 Ω), delivers 0.75–1.4 V/µs slew rate depending on supply, and maintains 1.75–1.81 MHz gain-bandwidth product across 3 V and 5 V operation - critical for accurate pulse response in automotive sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct connection to 3.3 V and 5 V automotive rails without regulation. |
| Input Offset Voltage (Max) | 950 µV at 25°C - enables high-accuracy DC-coupled amplification in precision sensor signal chains. |
| Gain-Bandwidth Product | 1.81 MHz (typ at 5 V) - sufficient for anti-aliasing filtering and moderate-speed signal conditioning before ADC sampling. |
| Output Drive Capability | ±3 mA into 600 Ω - drives standard telecom and industrial analog interface loads without external buffers. |
| Input Noise Density | 16 nV/√Hz at 1 kHz (5 V) - preserves SNR in low-level piezoelectric or thermopile transducer amplification. |
| Common-Mode Input Range | 0 V to 4.25 V (min at 5 V) - accepts signals down to ground, simplifying single-supply system design. |
| Quiescent Current | 750 µA per channel (typ) - enables always-on monitoring in power-constrained automotive ECUs. |
Pinout & Package
TSSOP-8 (PW) package, 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not present. RoHS-compliant, automotive-qualified reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail capable; drives 600 Ω load to within 0.02 V of VDD and 0.63 V of GND at 5 V. |
| 2 (IN−1) | Channel 1 inverting input | High-impedance CMOS node; 1 pA bias current enables high-Z source interfacing. |
| 3 (IN+1) | Channel 1 non-inverting input | Supports common-mode input down to VDD−; no phase inversion up to supply rails. |
| 4 (VDD− / GND) | Negative supply / ground reference | Single-supply operation: connected to system GND; dual-supply: connects to VSS. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent input stage; identical specs to Channel 1 for dual-sensor or differential pair use. |
| 6 (IN−2) | Channel 2 inverting input | Matched offset and bias characteristics enable precision instrumentation configurations. |
| 7 (OUT2) | Channel 2 output | Full rail-to-rail swing; synchronized settling time (≤3.2 µs to 0.01%) with Channel 1. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; internal ESD protection >2 kV HBM ensures robustness in automotive harness environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of VDD and 630 mV of GND at 5 V/3 mA - maximizes dynamic range for 12-bit+ ADCs. |
| No phase inversion | Stable operation even when common-mode input reaches VDD or GND - eliminates latch-up risk in sensor overvoltage events. |
| AEC-Q100 Grade 1 qualified | Rated for –40°C to 125°C ambient; validated for automotive powertrain, body control, and ADAS subsystems. |
| Low 16 nV/√Hz input noise | Preserves signal integrity in low-amplitude sensor paths (e.g., oxygen sensors, knock detection). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7322QDRQ1 | Higher 22 MHz GBW, 20 V/µs slew rate, but 2.1 mA/ch supply current and no guaranteed rail-to-rail output at light loads. | Better for high-speed active filters; less suitable for ultra-low-power always-on sensing. | Choose LM7322QDRQ1 when bandwidth >5 MHz is required and power budget allows >2× current draw. |
| TSV912AQDRQ1 | Lower 8 MHz GBW, 15 nV/√Hz noise, 150 µA/ch supply current, but only 1.8 V min supply and limited 3.5 V max output swing at 5 V. | Optimized for sub-2 V battery systems; insufficient output swing for 12-bit ADC full-scale drive at 5 V. | Choose TSV912AQDRQ1 for energy-harvesting nodes or 1.8 V microcontroller interfaces where swing margin is acceptable. |
Compared with LM7322QDRQ1 and TSV912AQDRQ1, TLV2442AQPWRG4Q1 uniquely balances 1.8 MHz bandwidth, rail-to-rail output, 750 µA/ch quiescent current, and AEC-Q100 Grade 1 qualification - making it optimal for cost-sensitive, thermally demanding automotive analog signal chains where precision, power, and reliability intersect.

FAQ
What is the maximum operating temperature range for TLV2442AQPWRG4Q1?
The TLV2442AQPWRG4Q1 is qualified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating is verified across all electrical parameters including input offset voltage, CMRR, and output drive capability - ensuring reliable performance in under-hood and cabin-mounted automotive modules.
Does TLV2442AQPWRG4Q1 support true rail-to-rail input?
No, TLV2442AQPWRG4Q1 provides rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from VDD− (GND) to VDD+ − 1 V - for example, 0 V to 4.25 V minimum at 5 V supply. This exceeds standard CMOS op-amps and eliminates need for level-shifting in most single-supply designs.
Can TLV2442AQPWRG4Q1 drive a 1000 pF capacitive load?
TLV2442AQPWRG4Q1 is characterized for stability with up to 100 pF capacitive load (RL = 600 Ω, φm = 65°). Driving 1000 pF directly risks oscillation; a series resistor (≥100 Ω) between output and capacitor is required to maintain phase margin above 45° per TI application guidance in SGLS181C.
What is the typical input bias current of TLV2442AQPWRG4Q1?
The typical input bias current of TLV2442AQPWRG4Q1 is 1 pA at 25°C, with a maximum of 260 pA across –40°C to +125°C. This ultra-low value enables accurate amplification of high-impedance sources such as thermocouples, pH electrodes, and piezoelectric sensors without significant error from leakage paths.
Is TLV2442AQPWRG4Q1 pin-compatible with TLV2442QPWRQ1?
Yes, TLV2442AQPWRG4Q1 and TLV2442QPWRQ1 share identical TSSOP-8 (PW) package, pinout, and footprint. The key difference is input offset voltage specification: TLV2442AQPWRG4Q1 guarantees ≤950 µV max at 25°C, while TLV2442QPWRQ1 specifies ≤2.5 mV - making the 'A' variant preferred for higher-precision applications.
