Product details
Overview
TLV2444AQPWRQ1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V) operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, 950 µV max input offset voltage at 25°C, and full rail-to-rail output swing - enabling high-precision signal conditioning in battery-powered automotive sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2444AQPWRQ1 datasheet, TLV2444AQPWRQ1 pinout, TLV2444AQPWRQ1 application, or TLV2444AQPWRQ1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 1 pA typical input bias current, 16 nV/√Hz input voltage noise at 1 kHz, extended common-mode input range (0 V to 4.25 V min at 5 V), and 600-Ω load drive capability.
Technical Context
The TLV2444AQPWRQ1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion when inputs approach supply rails - eliminating need for costly rail-to-rail input amplifiers in many automotive front-end designs. Its architecture supports stable operation with 600-Ω loads and 100 pF capacitive loads while maintaining ≥65° phase margin.
Characterized across –40°C to 125°C and fully specified at both 3 V and 5 V supplies, the device features low-noise (16 nV/√Hz typ), low-offset (950 µV max), and low-power (750 µA/ch typ) operation - making it suitable for precision analog signal chains in engine control units, ADAS sensor signal conditioning, and body electronics where supply headroom and thermal robustness are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide automotive battery voltage variation including cold-crank (≥2.7 V) and load-dump transients (≤10 V). |
| Gain-Bandwidth Product | 1.8 MHz (typ at 5 V) - enables stable closed-loop operation up to ~100 kHz with moderate gain in sensor interface circuits. |
| Input Offset Voltage | 950 µV max at 25°C - ensures ≤0.02% error in 5 V full-scale single-supply systems without trimming. |
| Input Bias Current | 1 pA (typ) - preserves signal integrity when driving from high-impedance sources like piezoelectric sensors or thermistors. |
| Output Drive Capability | ±3 mA into 600 Ω at 5 V - directly drives SAR ADC reference buffers and low-impedance transducer interfaces without external buffers. |
| Common-Mode Input Range | 0 V to 4.25 V (min at 5 V) - accepts ground-referenced signals and supports single-supply operation with full dynamic range utilization. |
| Supply Current per Channel | 750 µA (typ at 25°C) - enables four-channel precision amplification in power-constrained modules (e.g., <3 mA total quiescent current). |
Pinout & Package
TSSOP-14 package (PW), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | IN− (Inverting Input) | Differential input node for each of four independent op-amp channels; high-impedance (1000 GΩ) CMOS input. |
| 2, 6, 9, 13 | IN+ (Non-Inverting Input) | Differential input node for each channel; supports common-mode voltage down to VDD− (GND) and up to VDD+ − 1 V. |
| 3, 7, 10, 14 | OUT (Output) | Rail-to-rail output capable of swinging within 25 mV of VDD− and 63 mV of VDD+ at 3 mA load (5 V supply). |
| 4 | VDD+ | Positive supply terminal; accepts 2.7 V to 10 V; decoupling required near pin for stability with capacitive loads. |
| 11 | VDD− / GND | Negative supply / ground reference; serves as return path for all four channels and internal bias circuitry. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2444QPWRQ1 | Higher max input offset voltage (2.5 mV vs. 950 µV); same pinout, package, and AEC-Q100 Grade 1 rating. | Suitable for cost-sensitive non-precision automotive functions (e.g., basic voltage monitoring) where tighter offset isn't required. | Select TLV2444QPWRQ1 only when 2.5 mV VIO is acceptable - avoids paying premium for A-grade performance where unnecessary. |
| LMV844QDGKRQ1 | Higher supply current (1.2 mA/ch), lower GBW (1.2 MHz), no rail-to-rail output (output swing limited to 100 mV from rails). | Better suited for general-purpose amplification where rail-to-rail output and ultra-low bias current are not critical. | Choose LMV844QDGKRQ1 if design tolerates reduced dynamic range and higher power; avoid when driving ADCs or high-Z sensors. |
Compared with TLV2444QPWRQ1 and LMV844QDGKRQ1, the TLV2444AQPWRQ1 provides superior precision (950 µV VIO), lower power (750 µA/ch), and true rail-to-rail output - making it the optimal choice for automotive signal chains demanding accuracy, efficiency, and interface compatibility with modern ADCs.

FAQ
What is the operating temperature range for the TLV2444AQPWRQ1?
The TLV2444AQPWRQ1 is qualified per AEC-Q100 Grade 1 and operates across –40°C to +125°C ambient temperature. All electrical specifications - including input offset voltage, supply current, and gain-bandwidth - are guaranteed over this full range, making it suitable for under-hood and transmission-control applications where thermal stress is extreme.
Does the TLV2444AQPWRQ1 support rail-to-rail input operation?
No, the TLV2444AQPWRQ1 features rail-to-rail *output* 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 allows ground-referenced inputs but does not accept signals beyond the positive rail, unlike true rail-to-rail input amplifiers.
Can the TLV2444AQPWRQ1 drive a 100 pF capacitive load stably?
Yes, the TLV2444AQPWRQ1 is characterized for stable operation with 100 pF capacitive loads and 600-Ω series resistance, maintaining ≥65° phase margin at unity gain. Data sheet Figure 19 confirms stable large-signal pulse response under these conditions at both 3 V and 5 V supplies - enabling direct connection to ADC input capacitors without isolation resistors.
What is the maximum output current capability of the TLV2444AQPWRQ1?
The TLV2444AQPWRQ1 delivers ±3 mA output current into 600 Ω while maintaining rail-to-rail swing (e.g., VOH = 4.35 V, VOL = 0.8 V at 5 V supply). Absolute maximum ratings allow ±50 mA short-circuit current, but continuous operation above ±3 mA requires careful thermal management due to dissipation limits in the TSSOP-14 package.
Is there a SPICE model available for the TLV2444AQPWRQ1?
Yes, Texas Instruments provides a PSpice macromodel for the TLV2444AQPWRQ1, referenced in the datasheet as "Macromodel Included." The model is validated for AC, transient, and DC performance across temperature and supply voltage, supporting accurate simulation of closed-loop behavior, noise, and settling time in automotive signal chain designs.
