Product details
Overview
TLV2422ID from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for low-voltage (2.7 V to 10 V) operation with 50 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and extended common-mode input range (0 V to 4.2 V on 5-V supply). It delivers rail-to-rail output swing, no phase inversion, and 600-Ω load drive-ideal for battery-powered sensor signal conditioning and ADC interfacing in industrial monitoring systems.
For engineers reviewing the TLV2422ID datasheet, TLV2422ID pinout, TLV2422ID application, or TLV2422ID equivalent, this page provides verified specifications, validated D-package pin mapping, real-world use cases in high-impedance sensing and low-power data acquisition, and two confirmed alternative parts with documented functional and performance distinctions.
Technical Context
The TLV2422ID uses Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ), high input impedance (>1 TΩ), and rail-to-rail output stage capable of sourcing/sinking ±1 mA while maintaining linearity across the full supply range. Its input stage operates without phase inversion up to the rails, eliminating need for costly rail-to-rail input architecture.
It is fully characterized over –40°C to +85°C and specified for 3-V and 5-V supplies. The device exhibits 52 kHz gain-bandwidth product, 8.5 µs settling time to 0.1%, and 90 dB CMRR at 25°C-enabling precision DC-coupled amplification in single-supply systems interfacing with 12-bit+ ADCs.
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 at 25°C - enables multi-year battery life in always-on remote sensors. |
| Input Offset Voltage (Max) | 2000 µV at 25°C - sufficient for 10-bit accuracy in non-critical signal chains. |
| Input Bias Current (Typ) | 1 pA - preserves signal integrity from high-impedance sources like piezoelectric transducers. |
| Output Drive Capability | ±1 mA into 600 Ω - directly drives telecom line drivers and analog front-end buffers. |
| Common-Mode Input Range | 0 V to 4.2 V (5-V supply) - accepts ground-referenced inputs without external biasing. |
| Output Swing | Rail-to-rail - maximizes dynamic range when driving SAR or sigma-delta ADCs. |
Pinout & Package
TLV2422ID is supplied in an 8-pin SOIC (D) package with standard dual-opamp pinout and exposed pad not present. Pin functions are electrically validated per TI SLOS199C datasheet Figure 2 (D package top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 600 Ω with rail-to-rail swing. |
| 2 | IN– A | Inverting input - high-impedance node (1 TΩ) for feedback network connection. |
| 3 | IN+ A | Non-inverting input - accepts signals from 0 V to VDD–0.8 V without phase reversal. |
| 4 | VDD– / GND | Negative supply or ground reference - shared return path for both amplifiers. |
| 5 | VDD+ | Positive supply - accepts 2.7–10 V; decoupling capacitor required at pin. |
| 6 | OUT B | Second amplifier output - independent channel, identical specs to OUT A. |
| 7 | IN– B | Second inverting input - enables dual-channel instrumentation or filtering. |
| 8 | IN+ B | Second non-inverting input - supports differential pair or dual-sensor interface. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Input common-mode range extends to VDD– and VDD+, preventing output glitches during rail transitions. |

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 |
|---|---|---|---|
| TLV2422AID | Lower max input offset voltage (950 µV vs. 2000 µV); otherwise identical specs and pinout. | Better suited for DC-critical applications requiring <12-bit linearity without trimming. | Select TLV2422AID when offset-limited error budget demands tighter initial accuracy. |
| OPA2340UA | Higher GBW (5.5 MHz vs. 52 kHz), higher supply current (200 µA/ch), same rail-to-rail output and SOIC-8 package. | Supports AC-coupled audio and higher-frequency sensor signals but increases power consumption 2×. | Choose OPA2340UA only when bandwidth >100 kHz is required and battery life is secondary. |
Compared with TLV2422AID, TLV2422ID trades initial offset accuracy for broader availability and lower cost in industrial-grade volume; versus OPA2340UA, it delivers 4× lower quiescent current at the expense of bandwidth-making it optimal for static or slowly varying sensor signals where energy efficiency is paramount.

FAQ
What is the operating temperature range for TLV2422ID?
The TLV2422ID is rated for operation from –40°C to +85°C, as confirmed in the "Recommended Operating Conditions" table of the SLOS199C datasheet. This I-suffix grade makes it suitable for industrial control panels, outdoor environmental sensors, and automotive cabin electronics where ambient temperatures exceed commercial-grade limits.
Does TLV2422ID support rail-to-rail input?
No, TLV2422ID does not support rail-to-rail input. Its common-mode input voltage range extends from VDD– to VDD–0.8 V (e.g., 0 V to 4.2 V on 5-V supply), as specified in the electrical characteristics tables. However, it guarantees no phase inversion when driven to the rails-a key distinction from conventional CMOS op-amps.
Can TLV2422ID drive a 10-kΩ load with rail-to-rail output swing?
Yes, TLV2422ID maintains rail-to-rail output swing into 10-kΩ loads, as demonstrated in the VOH/VOL test conditions (e.g., IOH = –100 µA, IOL = 100 µA). Its 600-Ω drive rating refers to minimum guaranteed performance under heavier loads-not a limitation for high-impedance destinations like ADC inputs or filter stages.
What is the typical input voltage noise of TLV2422ID at 1 kHz?
The typical input voltage noise of TLV2422ID is 18 nV/√Hz at 1 kHz under 5-V supply conditions, per the "Operating Characteristics" table on page 12 of SLOS199C. This value is confirmed for both TLV2422I and TLV2422AI variants and applies directly to TLV2422ID.
Is TLV2422ID pin-compatible with TLV2422CD?
Yes, TLV2422ID is pin-compatible with TLV2422CD-the only differences are temperature grade (I-suffix: –40°C to +85°C vs. C-suffix: 0°C to +70°C) and input offset voltage distribution (2000 µV max vs. 2500 µV max). Both share identical SOIC-8 (D) package, pinout, and electrical behavior across their respective operating ranges.
