Product details
Overview
TLV2442IDR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, wide-input-voltage operation. It delivers 1.8 MHz gain-bandwidth, 750 µA per channel supply current, and 16 nV/√Hz input voltage noise at 1 kHz - enabling precision signal conditioning in battery-powered sensor interfaces and ADC driver stages. Its extended common-mode input range (0 V to 4.25 V min at 5-V supply) and no-phase-inversion behavior support robust operation near supply rails.
For engineers reviewing the TLV2442IDR datasheet, TLV2442IDR pinout, TLV2442IDR application, or TLV2442IDR equivalent, key selection criteria include rail-to-rail output swing into 600-Ω loads, ≤950 µV max input offset voltage (at 25°C), −40°C to 85°C industrial temperature rating, SOIC-8 packaging, and compatibility with 2.7-V to 10-V single-supply systems.
Technical Context
The TLV2442IDR uses Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ), ultra-low input bias current (1 pA typ), and rail-to-rail output swing without phase inversion when common-mode inputs reach either supply rail. Its internal architecture supports stable unity-gain operation with 600-Ω load drive capability and 65° phase margin at 1 MHz.
It is fully characterized across 3-V and 5-V supplies, with guaranteed performance over −40°C to +85°C. The device exhibits low 1.4 V/µs slew rate (at 5 V), 70 dB CMRR (min), and 80 dB supply-voltage rejection ratio - making it suitable for mixed-signal systems where analog front-end accuracy must coexist with digital noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation in portable and industrial 3.3-V/5-V systems. |
| Gain-Bandwidth Product | 1.8 MHz typ - enables stable closed-loop gain up to ~10× at audio and low-speed control frequencies. |
| Input Offset Voltage | ≤950 µV max at 25°C - ensures sub-millivolt DC error in precision amplification and sensor offset correction. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like piezoelectric transducers. |
| Output Drive Capability | 600-Ω load at full rail-to-rail swing - directly interfaces with legacy ADC reference inputs and analog multiplexers. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5-V supply - allows direct sensing of signals referenced to ground or near VDD without level-shifting. |
| Supply Current per Channel | 750 µA typ - enables dual-channel amplification in space-constrained, low-power IoT nodes. |
Pinout & Package
TLV2442IDR is housed in an 8-pin SOIC (D) package with standard dual-opamp pinout and no internal connections on unused pins. Pin 1 is 1OUT; pin 2 is 1IN–; pin 3 is 1IN+; pin 4 is VDD–/GND; pin 5 is 2IN+; pin 6 is 2IN–; pin 7 is 2OUT; pin 8 is VDD+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail voltage swing; drives 600-Ω loads with <1 V headroom at 5 V supply. |
| 2 | Channel 1 Inverting Input | High-impedance node (1000 GΩ); accepts signals within 0 V to 4.25 V at 5 V supply. |
| 3 | Channel 1 Non-Inverting Input | Same common-mode range as pin 2; no phase inversion when driven to rails. |
| 4 | Negative Supply / Ground | Reference for dual-supply (±VDD) or ground return in single-supply configurations. |
| 5 | Channel 2 Non-Inverting Input | Independent high-Z input; identical specs to pin 3. |
| 6 | Channel 2 Inverting Input | Independent high-Z input; identical specs to pin 2. |
| 7 | Channel 2 Output | Functionally identical to pin 1; enables dual independent gain stages. |
| 8 | Positive Supply | Accepts 2.7–10 V; powers both amplifiers; decoupling capacitor required at this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives full 0 V to VDD range into 600-Ω loads - eliminates need for level-shifting before ADC inputs. |
| No phase inversion | Operates linearly even when common-mode input reaches VDD or GND - prevents latch-up in sensor buffer applications. |
| Low input offset voltage (≤950 µV) | Reduces DC error in precision instrumentation chains, such as thermocouple or strain gauge amplifiers. |
| Ultra-low input bias current (1 pA) | Minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiodes), preserving signal fidelity. |
| Wide input voltage range (0 V to 4.25 V min) | Supports direct interfacing with 0–5 V sensors and microcontroller GPIOs without external resistive dividers. |
| Low-noise operation (16 nV/√Hz) | Enables clean amplification of µV-level signals in medical ECG front-ends and audio preamps. |

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 |
|---|---|---|---|
| OPA2340UA | Higher 5.5 MHz GBW, 200 µV max VIO, but 1.6 mA/ch supply current and narrower 2.7–5.5 V supply range. | Better for higher-speed precision filtering; less suitable for ultra-low-power battery systems. | Select when bandwidth >2 MHz and offset <200 µV are critical; avoid if supply current budget <1 mA/ch. |
| MCP6022-I/SN | Lower 10 µV max VIO, 1.2 mA/ch supply current, 10 MHz GBW, but only specified for 2.7–6.0 V and lacks guaranteed rail-to-rail output into 600 Ω. | Preferred for zero-drift DC-critical applications; not recommended for legacy 5-V ADC drivers requiring full swing. | Choose for sub-10-µV offset needs in lab-grade instruments; verify output swing under 600-Ω load before use. |
Compared with OPA2340UA and MCP6022-I/SN, TLV2442IDR provides the optimal balance of rail-to-rail 600-Ω drive, 750 µA/ch power, and 950 µV offset in industrial temperature-rated SOIC-8 - making it uniquely suited for cost-sensitive, battery-aware analog front-ends where moderate speed suffices.

FAQ
What is the operating temperature range for TLV2442IDR?
The TLV2442IDR is rated for −40°C to +85°C industrial operation, as confirmed by its "I" suffix and the Absolute Maximum Ratings table in the SLOS169H datasheet. This range is validated across all electrical parameters including input offset voltage, CMRR, and output drive capability - ensuring reliability in factory-floor and outdoor deployed systems.
Does TLV2442IDR support true rail-to-rail output swing into 600 Ω?
Yes, TLV2442IDR guarantees rail-to-rail output swing into 600-Ω loads per the datasheet's "600-Ω Output Drive" feature and Figure 10 (VOH vs IOH at 5 V). At 25°C and 5-V supply, VOH ≥ 4.0 V and VOL ≤ 0.8 V under 5-mA load - delivering >95% of full-scale swing, critical for driving legacy ADC references without external buffers.
Is TLV2442IDR pin-compatible with other dual op-amps in SOIC-8?
TLV2442IDR follows the industry-standard dual-opamp pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VDD+), matching devices like LM2904, TL072, and OPA2340. However, functional compatibility requires verification of supply range, input/output swing, and bias current - as TLV2442IDR's 1-pA IIB and rail-to-rail output differ significantly from bipolar predecessors.
Can TLV2442IDR operate from a 3-V supply?
Yes, TLV2442IDR is fully specified down to 2.7 V, with tested performance at 3 V in both Electrical Characteristics and Operating Characteristics tables. At 3 V, it maintains 1.75 MHz GBW, 725 µA/ch supply current, and rail-to-rail output swing - making it ideal for single-cell Li-ion or two-cell alkaline systems.
What is the maximum capacitive load TLV2442IDR can drive stably?
TLV2442IDR maintains 65° phase margin with 100 pF capacitive load and 600-Ω series resistance, as shown in Figure 19 and the Operating Characteristics table. Driving >100 pF directly may cause peaking or oscillation; for larger loads, add a 10-Ω isolation resistor in series with the output or use a dedicated buffer stage.
