Product details
Overview
TLV2442AID 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, 750 µA per channel supply current, and 600-Ω output drive capability. It enables precision signal conditioning in battery-powered sensor interfaces and single-supply data acquisition systems interfacing with ADCs.
For engineers reviewing the TLV2442AID datasheet, TLV2442AID pinout, TLV2442AID application, or TLV2442AID equivalent, key selection criteria include guaranteed rail-to-rail output swing (0 V to VDD–1 V at 5 V), extended common-mode input range (0 V to 4.25 V min at 5 V), no phase inversion, and automotive-grade temperature range (–40°C to 85°C).
Technical Context
The TLV2442AID uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ), ultra-low input bias current (1 pA typ), and low noise (16 nV/√Hz at 1 kHz). Its internal architecture avoids phase inversion when common-mode inputs reach either supply rail, eliminating need for external clamping in wide-dynamic-range sensing.
It delivers rail-to-rail output performance across its full operating temperature range, with output voltage swing specified down to 0.01 V above VDD– and up to VDD–1.0 V at 5 V - enabling full utilization of ADC input ranges without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-cell Li-ion, 3.3 V, and 5 V systems without level translation. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤0.02% error in 5 V full-scale precision amplification. |
| Gain-Bandwidth Product | 1.8 MHz typ at VDD = 5 V - enables stable unity-gain buffering up to ~1.5 MHz with 600-Ω load. |
| Output Drive Capability | 600-Ω load drive - sustains rail-to-rail swing into telecom and instrumentation loads without external buffers. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V supply - accepts signals from ground to near-VDD, simplifying sensor front-end design. |
| Supply Current (per channel) | 750 µA typ at VDD = 5 V - enables dual-channel precision amplification in sub-1.5 mA total system power budgets. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance sources like piezoelectric transducers and pH electrodes. |
Pinout & Package
TLV2442AID is housed in an 8-pin SOIC (D) package with standard dual op-amp pinout and exposed pad not present. Pin functions are validated per TI SLOS169H datasheet Figure 1 (D-package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 4 | VDD– / GND | Power return for dual-supply operation or ground reference for single-supply use. |
| 5 | Non-inverting input (Channel 2) | Independent second channel input; identical specs and rail-to-rail CMVR as Channel 1. |
| 6 | Inverting input (Channel 2) | Second channel feedback or signal path; no crosstalk impact on Channel 1 performance. |
| 7 | Output (Channel 2) | Fully independent output with same rail-to-rail swing and drive strength as Channel 1. |
| 8 | VDD+ | Positive supply rail; operates from 2.7 V to 10 V with no external charge pump required. |
Key Features

FAQ
What is the maximum guaranteed input offset voltage for TLV2442AID at 25°C?
The TLV2442AID has a maximum input offset voltage of 950 µV at TA = 25°C, as specified in the Electrical Characteristics table for VDD = 3 V and 5 V conditions. This value is guaranteed across the device's production lot and forms the basis for precision DC-coupled designs using TLV2442AID in instrumentation and sensor front-ends.
Does TLV2442AID support true rail-to-rail output swing at 3.3 V supply?
Yes, TLV2442AID supports rail-to-rail output swing at 3.3 V supply. At VDD = 3.3 V, the output can swing to within 0.01 V of VDD– (GND) and to at least VDD–1.0 V (≥2.3 V), per characterization data in the datasheet's VOH/VOL specifications. This enables full utilization of 3.3 V ADC input ranges without external level-shifting circuitry.
What is the operating temperature range for TLV2442AID?
The TLV2442AID is rated for operation from –40°C to +85°C, as indicated by the "I" temperature suffix in the part number. This industrial-grade range is validated across all electrical parameters including input offset voltage, CMRR, and output drive capability, making TLV2442AID suitable for deployment in harsh ambient environments such as factory floors and automotive cabins.
Can TLV2442AID drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, TLV2442AID is explicitly characterized to drive 600-Ω loads while maintaining rail-to-rail output swing. The datasheet specifies VOH ≥2.5 V and VOL ≤0.63 V at IO = ±3 mA with VDD = 5 V, confirming full swing capability into 600 Ω. This feature is leveraged in telecom line drivers and precision ADC interface circuits where load matching is critical.
Is TLV2442AID compatible with single-supply operation?
Yes, TLV2442AID is fully compatible with single-supply operation from 2.7 V to 10 V. Its extended common-mode input range (0 V to VDD–1 V) and rail-to-rail output swing allow direct connection to ground-referenced sensors and seamless interfacing with single-supply ADCs - eliminating need for dual supplies or level-shifting components in TLV2442AID-based designs.
