Product details
Overview
TLV2442AQPWR from Texas Instruments is a dual-channel, rail-to-rail output, wide-input-voltage operational amplifier optimized for automotive-grade operation (–40°C to +125°C). It delivers 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, 750 µA per channel supply current, and 600-Ω output drive capability-enabling precision signal conditioning in low-voltage sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2442AQPWR datasheet, TLV2442AQPWR pinout, TLV2442AQPWR application, or TLV2442AQPWR 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 near rails, low 16 nV/√Hz input noise at 1 kHz, and Q-Temp automotive qualification per AEC-Q100.
Technical Context
The TLV2442AQPWR uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ differential and common-mode resistance), ultra-low input bias current (1 pA typ), and rail-to-rail output swing without phase reversal when common-mode inputs reach either supply rail. Its architecture supports stable unity-gain operation with 65° phase margin into 600-Ω loads and 100 pF capacitive load.
It is fully characterized across 2.7 V to 10 V supply range and optimized for single-supply systems requiring wide dynamic range-especially where interfacing with 12-bit+ ADCs or driving telecom-grade 600-Ω impedances. Input offset voltage drift is specified at 2 µV/°C, and long-term drift is 0.002 µV/month.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - Enables direct operation from Li-ion battery (3.3 V), 5-V logic rails, or industrial 9-V supplies without regulation. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - Supports precision DC-coupled amplification in strain gauge or thermopile sensor front-ends. |
| Gain-Bandwidth Product | 1.8 MHz typ at VDD = 5 V - Sufficient for anti-aliasing filters up to ~100 kHz and closed-loop gains ≤10 with stable response. |
| Output Drive Capability | 600-Ω load - Directly drives legacy telecom line interfaces, SAR ADC reference buffers, and instrumentation DAC outputs. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5-V supply - Accepts inputs down to ground and up to within 250 mV of VDD, eliminating level-shifting in single-supply designs. |
| Supply Current (per channel) | 750 µA typ at VDD = 5 V - Enables dual op-amp functionality in power-constrained automotive body control modules and remote sensors. |
| Input Noise Voltage | 16 nV/√Hz typ at f = 1 kHz - Low enough for microvolt-level signal amplification from piezoelectric or electret microphone sources. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail swing: 0.02 V above VDD– and 0.63 V below VDD+ at 3 mA load (5 V supply). |
| 2 (IN1–) | Channel 1 inverting input | High-impedance node (1000 GΩ); accepts signals from high-Z sources like pH electrodes or photodiodes. |
| 3 (IN1+) | Channel 1 non-inverting input | Same high-Z interface; enables precision difference amplification with matched external resistors. |
| 4 (GND / VDD–) | Negative supply / ground reference | Single-supply operation: tied to system ground; dual-supply: connects to negative rail. |
| 5 (IN2+) | Channel 2 non-inverting input | Independent input path; supports dual-sensor monitoring or active filter topologies. |
| 6 (IN2–) | Channel 2 inverting input | Matched performance to Pin 2; allows identical feedback networks for both channels. |
| 7 (OUT2) | Channel 2 output | Identical rail-to-rail output behavior as Pin 1; supports independent signal paths or parallel drive. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; internal ESD protection rated to ±2 kV HBM; decoupling capacitor required at pin. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Eliminates output glitches during input transients crossing supply rails-critical for motor current sensing and overvoltage detection circuits. |
| Rail-to-rail output | Delivers full 0 V to VDD swing under 600-Ω load, maximizing ADC utilization and dynamic range in 3.3-V or 5-V systems. |
| Extended common-mode range | Operates with inputs from VDD– to VDD+ – 1.3 V (at 125°C), enabling direct connection to resistive divider outputs or unbuffered sensor bridges. |
| Low input bias current | 1 pA typical ensures minimal error in high-impedance transducer interfaces (e.g., >10 MΩ source impedance) without guard traces or active guarding. |
| Q-Temp automotive qualification | Qualified per AEC-Q100 Grade 1 (–40°C to +125°C), with configuration control and production traceability for safety-critical vehicle subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442IPW | Same pinout and architecture, but rated for –40°C to +85°C only; 2.5 mV max VIO vs. 950 µV. | Suitable for commercial/industrial environments without extended temperature requirements. | Select TLV2442IPW only if automotive qualification and tighter offset spec are unnecessary. |
| MCP6022-E/SN | Microchip device; 1.8 MHz GBW, 150 µA/ch supply current, 2.5 mV max VIO, 2.7–6 V supply range. | Lacks AEC-Q100 qualification; lower power but higher offset limits precision in DC-coupled sensor paths. | Choose MCP6022-E/SN for ultra-low-power battery applications where offset and temperature range are less critical. |
Compared with TLV2442IPW and MCP6022-E/SN, the TLV2442AQPWR uniquely combines automotive temperature range, sub-millivolt offset, and 600-Ω drive-making it the only option qualified for safety-relevant automotive cabin and powertrain signal conditioning where reliability and precision coexist.

FAQ
What is the maximum operating temperature range for TLV2442AQPWR?
The TLV2442AQPWR is qualified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating is confirmed in the "Recommended Operating Conditions" table of the official datasheet (SLOS169H), where Q-suffix devices specify TA = –40°C to 125°C across all electrical parameters including input offset voltage, CMRR, and supply current.
Does TLV2442AQPWR support true rail-to-rail input operation?
No, TLV2442AQPWR features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD– to VDD+ – 1.3 V at 125°C (min 0 V to 4.25 V at 5 V supply, 25°C), which exceeds standard CMOS op-amps but does not include the positive rail. Input phase inversion is avoided, however, even when driven to the rails.
Can TLV2442AQPWR drive a 1000-pF capacitive load stably?
The TLV2442AQPWR is characterized for stability with 100 pF capacitive load and 600-Ω series resistance (see Figure 19–20, Phase Margin plots). Driving 1000-pF directly may cause peaking or oscillation; a small series resistor (≥10 Ω) or isolation buffer is recommended for larger capacitive loads to maintain ≥45° phase margin.
What is the typical input bias current of TLV2442AQPWR at 125°C?
Per the "Electrical Characteristics" tables (pages 5–8, SLOS169H), the TLV2442AQ and TLV2442AM variants specify a maximum input bias current of 260 pA over full temperature range (–40°C to 125°C). At 125°C specifically, typical data shows ~350 pA for TLV2442M/AM, confirming TLV2442AQPWR remains in the low-picoampere range even at maximum junction temperature.
Is TLV2442AQPWR pin-compatible with other devices in the TLV244x family?
Yes, TLV2442AQPWR shares identical TSSOP-8 pinout with all TLV2442x variants (e.g., TLV2442CD, TLV2442IPW, TLV2442AID). Pin functions-OUT1, IN1–, IN1+, GND, IN2+, IN2–, OUT2, VDD+-are consistent across the family, enabling drop-in replacement where temperature, offset, and qualification requirements align.
