Product details
Overview
TLV2442AIPWG4 from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage operation (2.7 V to 10 V), featuring 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, and 600-Ω output drive capability. It delivers extended common-mode input range (0 V to 4.25 V min at 5 V supply), no phase inversion, and 16 nV/√Hz input voltage noise - enabling precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2442AIPWG4 datasheet, TLV2442AIPWG4 pinout, TLV2442AIPWG4 application, or TLV2442AIPWG4 equivalent, key selection criteria include its guaranteed 950 µV VIO max over temperature, rail-to-rail output swing into 600-Ω loads, and compatibility with single-supply 3 V/5 V systems requiring wide-input-voltage-range amplification without rail-to-rail input circuitry.
Technical Context
The TLV2442AIPWG4 employs 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 stable unity-gain operation with 65° phase margin at 600-Ω load and 100-pF capacitance. Its architecture avoids phase inversion when common-mode inputs reach either supply rail, eliminating need for costly rail-to-rail input op-amps in many industrial and automotive front-end designs.
It is fully characterized across –40°C to +85°C (I-suffix grade) and supports both single-supply (e.g., 3 V, 5 V) and split-supply configurations. The device exhibits 0.75 V/µs slew rate at 5 V, 750 µA per channel supply current, and maintains >70 dB CMRR up to 10 kHz - making it suitable for DC-coupled transducer amplification and multiplexed analog front-ends where offset stability and output headroom are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - operates from single-cell Li-ion (3.0 V) or two-cell alkaline (3 V) up to industrial 10 V rails |
| Input Offset Voltage (max) | 950 µV at 25°C - enables <1 LSB error in 12-bit ADC interfacing with 5 V reference |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - supports closed-loop gains up to ~180 at 10 kHz for anti-alias filtering |
| Output Drive Capability | 600-Ω load - drives telecom line drivers, SAR ADC reference buffers, and active filters without external buffering |
| Input Voltage Noise | 16 nV/√Hz at 1 kHz - preserves SNR in low-level piezoelectric or thermopile sensor amplification |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V - accepts ground-referenced signals and supports level-shifting in mixed-supply systems |
| Supply Current per Channel | 750 µA typ - enables dual-channel operation in sub-2 mA total system power budgets |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail swing: 0.02 V to 4.97 V at 5 V supply, supports direct connection to 12-bit ADC inputs |
| 2 (–IN1) | Channel 1 inverting input | High-impedance node (1 TΩ); requires guarded layout for <1 pA leakage-sensitive applications |
| 3 (+IN1) | Channel 1 non-inverting input | Accepts common-mode voltages down to VDD– (GND) - enables true single-supply sensor biasing |
| 4 (VDD–/GND) | Negative supply / ground | Reference for all inputs and outputs in single-supply mode; must be low-impedance for noise immunity |
| 5 (+IN2) | Channel 2 non-inverting input | Independent of Channel 1; supports dual-sensor readout or composite filter topologies |
| 6 (–IN2) | Channel 2 inverting input | Matched bias current with Pin 2 - critical for low-offset differential amplifiers |
| 7 (OUT2) | Channel 2 output | Identical AC/DC performance to OUT1; allows independent gain/feedback networks per channel |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor required within 5 mm for stability with capacitive loads |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Prevents catastrophic output latch-up when common-mode input exceeds supply rails - eliminates need for input clamping diodes |
| Rail-to-rail output | Delivers full 0 V to VDD swing into 600-Ω loads, maximizing dynamic range for 3 V/5 V ADCs and DACs |
| Low input offset voltage (950 µV max) | Guaranteed over –40°C to +85°C - reduces calibration overhead in factory-trimmed industrial sensors |
| Ultra-low input bias current (1 pA typ) | Enables high-Z source interfacing (e.g., pH electrodes, photodiode transimpedance) without significant offset drift |
| Extended common-mode input range | 0 V to VDD–1 V at 5 V - supports direct connection of ground-referenced transducers without level-shifting |

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 |
|---|---|---|---|
| TLV2442CDR | Same architecture but C-suffix (0°C to 70°C), 2.5 mV max VIO - higher offset, commercial temp range | Suitable only for non-automotive consumer electronics; lacks extended temp qualification | Select TLV2442CDR only for cost-sensitive, room-temperature applications where 950 µV VIO is not required. |
| MCP6022-I/SN | Microchip device: 3.5 mV max VIO, 10 MHz GBW, 1 mA supply current - higher speed and power, looser DC specs | Better for AC-coupled audio or fast-settling data acquisition; less suitable for precision DC sensor gain stages | Choose MCP6022-I/SN when bandwidth >5 MHz is needed and offset drift tolerance exceeds ±2 mV. |
Compared with TLV2442CDR and MCP6022-I/SN, the TLV2442AIPWG4 provides the lowest guaranteed input offset voltage (950 µV) over industrial temperature range, optimal power-efficiency trade-off for battery-powered sensor nodes, and proven stability with capacitive loads - making it the preferred choice for precision, low-power, wide-temp analog front-ends.

FAQ
What is the maximum operating temperature range for the TLV2442AIPWG4?
The TLV2442AIPWG4 is rated for operation from –40°C to +85°C (I-suffix grade), validated per TI's industrial qualification standards. This range covers most industrial control, automotive cabin, and outdoor IoT sensor deployments. The device maintains specified performance including 950 µV max input offset voltage and 1.8 MHz gain-bandwidth product across this full range, as confirmed in the SLOS169H datasheet's electrical characteristics tables.
Does the TLV2442AIPWG4 support true rail-to-rail input operation?
No, the TLV2442AIPWG4 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 at 5 V supply (0 V to 4.25 V min), which exceeds standard CMOS op-amps but does not include the positive rail. For applications requiring input beyond VDD–1 V, a rail-to-rail input amplifier such as the TLV9062 should be considered instead of the TLV2442AIPWG4.
Can the TLV2442AIPWG4 drive a 1000-pF capacitive load stably?
The TLV2442AIPWG4 is characterized for stability with 100-pF capacitive loads and 600-Ω series resistance (per Figure 19–20 in SLOS169H). Driving 1000-pF directly may cause peaking or oscillation. To ensure stability, add a 100-Ω to 300-Ω isolation resistor between TLV2442AIPWG4 output and the capacitive load, or use a unity-gain buffer configuration with external compensation. Always verify phase margin >45° in final layout using SPICE simulation with the TLV2442AIPWG4 macromodel.
What is the typical supply current per channel for the TLV2442AIPWG4 at 3 V operation?
At 3 V supply and 25°C, the TLV2442AIPWG4 draws 725 µA per channel (typical), as specified in the "Electrical Characteristics" table on page 6 of SLOS169H. This value increases to ≤1100 µA per channel across the full –40°C to +85°C range. The low quiescent current enables dual-channel operation in sub-2.2 mA total system power budgets - ideal for coin-cell or energy-harvesting applications where the TLV2442AIPWG4 serves as the primary signal conditioner.
Is the TLV2442AIPWG4 pin-compatible with other devices in the TLV244x family?
Yes, the TLV2442AIPWG4 is pin-compatible with all TLV2442x variants in the TSSOP-8 (PW) package, including TLV2442CDR, TLV2442IDR, and TLV2442AIDR. Pin assignments (OUT1, –IN1, +IN1, GND, +IN2, –IN2, OUT2, VDD+) are identical across these variants. However, electrical specifications differ - notably input offset voltage (950 µV max for TLV2442AIPWG4 vs. 2.5 mV max for TLV2442CDR) and temperature range - so functional substitution requires validation against design requirements.
