Product details
Overview
TLV2422IDR from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 10 V) single- or split-supply operation. It delivers 50 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing - enabling high dynamic range signal conditioning in battery-powered sensor interfaces and precision analog front-ends.
For engineers reviewing the TLV2422IDR datasheet, TLV2422IDR pinout, TLV2422IDR application, or TLV2422IDR equivalent, this device is selected for ultra-low-power, wide-input-voltage amplification where phase inversion immunity, 600-Ω output drive capability, and extended common-mode input range (0 V to 4.5 V with 5-V supply) are critical design requirements.
Technical Context
The TLV2422IDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing without phase inversion across the full common-mode input range - a key differentiator versus standard CMOS op-amps. Its input stage operates down to VDD– and up to VDD+ – 0.8 V, supporting direct interfacing with ADCs and high-impedance sources like piezoelectric transducers.
Each amplifier exhibits 10¹² Ω differential and common-mode input resistance, 130 Ω closed-loop output impedance at 100 kHz, and stable unity-gain operation with 62° phase margin into 10 kΩ || 100 pF loads - making it suitable for low-noise, low-distortion (<0.25% THD+N) signal buffering and amplification in space-constrained industrial and automotive sensing systems.
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-shifting. |
| Supply Current per Channel | 100–150 µA (typ. 100 µA at 25°C) - enables multi-year battery life in remote sensors. |
| Input Offset Voltage (max) | 2000 µV at 25°C - sufficient for non-critical DC-coupled gain stages and signal conditioning. |
| Input Bias Current (typ.) | 1 pA - preserves signal integrity from high-impedance sources (e.g., pH electrodes, photodiodes). |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - compatible with telecom line drivers and DAC buffers. |
| Common-Mode Input Range | 0 V to 4.5 V (min) with 5-V supply - allows direct connection to microcontroller I/O pins and ADC references. |
| Gain-Bandwidth Product | 52 kHz at VDD = 5 V - suitable for DC to ~10 kHz applications including sensor amplification and filtering. |
Pinout & Package
TLV2422IDR is housed in an 8-pin SOIC (D) package (7.5 mm × 4.9 mm, 1.27 mm pitch), RoHS-compliant and tape-and-reel packaged (R suffix). The device features dual independent amplifiers with non-inverting/inverting inputs and outputs referenced to shared VDD+ and VDD–/GND rails.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Rail-to-rail output of amplifier 1 - connects directly to ADC input or next-stage buffer. |
| 2 | IN1– | Inverting input of amplifier 1 - used for feedback networks and differential configurations. |
| 3 | IN1+ | Non-inverting input of amplifier 1 - accepts high-impedance sensor signals with minimal loading. |
| 4 | VDD– / GND | Negative supply or ground reference - shared return path for both amplifiers and load currents. |
| 5 | VDD+ | Positive supply rail - powers both amplifiers; supports 2.7–10 V operation. |
| 6 | OUT2 | Rail-to-rail output of amplifier 2 - enables dual-channel signal processing on one die. |
| 7 | IN2– | Inverting input of amplifier 2 - supports independent gain-setting resistors per channel. |
| 8 | IN2+ | Non-inverting input of amplifier 2 - isolated from channel 1 for true dual-amplifier operation. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extends to both supply rails without output polarity reversal - eliminates need for rail-to-rail input op-amps in many designs. |
| Rail-to-rail output | Swings within 50 mV of VDD+ and VDD– at light loads - maximizes dynamic range when driving 12-bit+ ADCs. |
| Micropower operation | 100 µA per channel at 25°C - reduces thermal drift and enables always-on monitoring in portable equipment. |
| Low input noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level transducer signal chains (e.g., strain gauges, thermopiles). |
| Extended temperature range | –40°C to +85°C (I-suffix) - qualified for industrial control, automotive cabin modules, and outdoor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2422AIDR | Lower max input offset voltage (950 µV vs. 2000 µV); same package, pinout, and electrical specs otherwise. | Better suited for precision DC-coupled gain stages requiring <1 mV offset error. | Select TLV2422AIDR when offset-limited accuracy dominates power budget constraints. |
| MCP6022-I/SN | Higher supply current (180 µA/channel), wider GBW (1 MHz), but no guaranteed phase-inversion immunity. | Preferred for higher-speed AC-coupled applications where bandwidth >100 kHz is required. | Choose MCP6022-I/SN only if slew rate (0.6 V/µs) and GBW justify increased quiescent power. |
Compared with TLV2422AIDR, the TLV2422IDR trades 1050 µV higher input offset for identical micropower performance and cost; versus MCP6022-I/SN, it offers 3.6× lower supply current and guaranteed rail-to-rail input behavior but sacrifices bandwidth and speed-critical settling time.

FAQ
What is the maximum operating temperature range for TLV2422IDR?
The TLV2422IDR is rated for operation from –40°C to +85°C, meeting industrial temperature grade specifications. This range is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and output drive capability - ensuring reliable performance in harsh environments such as factory automation controllers and automotive cabin modules.
Does TLV2422IDR support rail-to-rail input operation?
No, TLV2422IDR does not support rail-to-rail input operation. Its common-mode input voltage range extends from VDD– to VDD+ – 0.8 V (e.g., 0 V to 4.2 V with 5-V supply). However, it provides rail-to-rail output swing and eliminates phase inversion - offering a practical compromise that avoids the complexity and cost of true rail-to-rail input op-amps in most sensor interface applications.
Can TLV2422IDR drive a 10-kΩ load while maintaining rail-to-rail output?
Yes, TLV2422IDR maintains rail-to-rail output swing into 10-kΩ loads. At 5 V supply, VOH ≥ 4.97 V and VOL ≤ 0.04 V with 100 µA load current - confirming full swing capability well within typical ADC input impedance requirements. Output voltage degradation begins only below 600 Ω, per the datasheet's 600-Ω drive specification.
Is TLV2422IDR pin-compatible with other devices in the TLV24xx family?
Yes, TLV2422IDR shares identical pinout and footprint with TLV2422AIDR, TLV2422CDR, and TLV2422QDR across the SOIC-8 (D) package. All variants use the same 1–8 pin mapping for OUT1, IN1–, IN1+, VDD–/GND, VDD+, OUT2, IN2–, and IN2+, enabling drop-in substitution where offset voltage or temperature grade permits.
What is the typical input voltage noise density of TLV2422IDR at 1 kHz?
The typical input voltage noise density of TLV2422IDR is 18 nV/√Hz at 1 kHz and 5 V supply, as specified in the "Operating Characteristics" table on page 12 of the SLOS199C datasheet. This value remains consistent across the I-suffix temperature range (–40°C to +85°C), making it predictable for low-noise sensor signal chain analysis.
