Product details
Overview
TLV2442CPWR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage operation (2.7 V to 10 V), featuring 1.8 MHz gain-bandwidth product, 750 µA per-channel supply current, and 950 µV max input offset voltage at 25°C. It delivers rail-to-rail output swing, extended common-mode input range (0 V to 4.25 V at 5 V supply), and no phase inversion-making it suitable for precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2442CPWR datasheet, TLV2442CPWR pinout, TLV2442CPWR application, or TLV2442CPWR equivalent, key selection criteria include its 600-Ω output drive capability, 16 nV/√Hz input voltage noise at 1 kHz, low 1 pA typical input bias current, and TSSOP-8 packaging for space-constrained analog front-ends.
Technical Context
The TLV2442CPWR employs Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ differential and common-mode resistance), low-noise performance, and stable unity-gain operation with 65° phase margin into 600 Ω + 100 pF loads. Its architecture avoids phase inversion when common-mode inputs reach either supply rail-a critical advantage over standard CMOS op-amps in single-supply transducer amplification.
It is fully characterized at 3 V and 5 V supplies, supports wide-input-voltage operation (VICR = 0 V to VDD–1 V), and maintains rail-to-rail output swing across –40°C to 85°C ambient temperature-enabling reliable use in industrial monitoring and automotive body electronics without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - Enables direct operation from single Li-ion cells or 3.3 V/5 V rails without regulation. |
| Gain-Bandwidth Product | 1.8 MHz typ - Supports stable closed-loop gain up to ~10× at 100 kHz for anti-aliasing filter drivers. |
| Input Offset Voltage | 950 µV max at 25°C - Ensures ≤0.5% error in 0.5 V full-scale 12-bit ADC interfacing. |
| Output Drive Capability | 600 Ω load - Directly drives telecom line drivers and SAR ADC reference buffers without external buffers. |
| Input Bias Current | 1 pA typ - Preserves signal integrity in high-impedance piezoelectric or pH sensor front-ends. |
| Common-Mode Input Range | 0 V to 4.25 V min at 5 V supply - Accepts ground-referenced inputs without level-shifting in single-supply systems. |
| Slew Rate | 0.75 V/µs typ at 5 V - Sustains 100 kHz full-power bandwidth for 2 VPP signals into 600 Ω. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm footprint, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±5 mA into 600 Ω. |
| 2 (IN–1) | Channel 1 inverting input | High-impedance node (1 TΩ); accepts common-mode voltages down to VDD–. |
| 3 (IN+1) | Channel 1 non-inverting input | Same high-Z and common-mode range as IN–1; no phase inversion up to supply rails. |
| 4 (GND / VDD–) | Negative supply / ground reference | Single-supply operation uses this as system ground; dual-supply connects to VDD–. |
| 5 (IN+2) | Channel 2 non-inverting input | Independent, matched input stage; identical specs and layout symmetry to Channel 1. |
| 6 (IN–2) | Channel 2 inverting input | Electrically isolated from Channel 1; enables dual-path signal conditioning on one die. |
| 7 (OUT2) | Channel 2 output | Functionally identical to OUT1; supports independent gain/feedback networks per channel. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; internal ESD protection rated to ±2 kV HBM. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of both supply rails at 5 mA load-maximizes dynamic range for 12-bit+ ADCs. |
| No phase inversion | Eliminates output glitches during input overdrive to supply rails-critical for sensor saturation recovery. |
| Low input bias current (1 pA) | Minimizes voltage error across high-value feedback resistors (>1 MΩ) in precision integrators. |
| Extended common-mode input range | Operates with inputs at GND or near VDD-enables direct connection of unbuffered thermocouples or current-sense shunts. |
| Low noise (16 nV/√Hz) | Preserves SNR in low-level signal chains (e.g., microphone preamps, strain gauge bridges) without added filtering. |
Applications
| Industrial Sensor Signal Conditioning | Portable Medical Instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2442AIPW | Same package and pinout; tighter 950 µV max VIO across full –40°C to 85°C range (vs. TLV2442CPWR's 2.5 mV max over 0°C to 70°C). | Required for industrial designs needing guaranteed offset spec over extended temperature. | Select TLV2442AIPW when full-temperature-range VIO stability is mandatory; TLV2442CPWR suffices for commercial-grade 0°C–70°C applications. |
| MCP6022-E/SN | Higher 10 MHz GBW but higher 1 mA supply current; 2.5 mV max VIO; same TSSOP-8 package. | Better for high-speed filtering but less suited for ultra-low-power portable designs. | Choose MCP6022-E/SN only if bandwidth >2 MHz is required and power budget allows +33% per-channel current. |
Compared with TLV2442AIPW, TLV2442CPWR trades guaranteed full-temperature VIO for lower cost in commercial applications; versus MCP6022-E/SN, it offers 25% lower supply current and superior low-frequency noise at the expense of bandwidth-making it optimal for precision, low-power, sub-1 MHz signal paths.

FAQ
What is the maximum supply voltage rating for TLV2442CPWR?
The absolute maximum supply voltage for TLV2442CPWR is 12 V across VDD+ and VDD–/GND terminals. Operation beyond this risks permanent damage. Recommended operating range is 2.7 V to 10 V, with full characterization at 3 V and 5 V. Exceeding 10 V may degrade long-term reliability even if within absolute max limits.
Does TLV2442CPWR support true rail-to-rail input operation?
No, TLV2442CPWR features 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 at 5 V supply-i.e., 0 V to 4 V-so inputs cannot reach the positive rail. This distinguishes it from rail-to-rail *input/output* op-amps like the TLV2772.
Can TLV2442CPWR drive a 1000 pF capacitive load stably?
TLV2442CPWR is characterized for stability with 100 pF capacitive load and 600 Ω series resistance. Driving 1000 pF directly may cause peaking or oscillation due to reduced phase margin. For heavy capacitive loads, add a 10–50 Ω isolation resistor in series with the output or use a unity-gain stable op-amp with higher C-load drive rating.
What is the thermal performance of TLV2442CPWR in TSSOP-8 package?
In TSSOP-8 (PW) package, TLV2442CPWR has a junction-to-ambient thermal resistance (θJA) of 238°C/W. At 750 µA per channel (1.5 mA total) and 5 V supply, power dissipation is ~7.5 mW, resulting in <2°C junction rise above ambient-well within safe operating limits even at 85°C ambient.
Is TLV2442CPWR qualified for automotive applications?
TLV2442CPWR (C-suffix, 0°C to 70°C) is not automotive-qualified. For automotive use, select TLV2442AQPW (Q-suffix, –40°C to 125°C) or TLV2442AIPW (I-suffix, –40°C to 85°C), both explicitly qualified to AEC-Q100 standards and listed in TI's Q-Temp automotive portfolio.
