Product details
Overview
TLV2422MJGB from Texas Instruments is a dual rail-to-rail output, micropower operational amplifier optimized for wide-input-voltage, low-power analog signal conditioning. It delivers 50 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing (0 V to VDD) with extended common-mode input range (0 V to 4.5 V min at 5-V supply). It is specified for –55°C to 125°C operation and used in high-impedance sensor interfaces and battery-powered remote sensing.
For engineers reviewing the TLV2422MJGB datasheet, TLV2422MJGB pinout, TLV2422MJGB application, or TLV2422MJGB equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and application-level differences - all aligned to the M-suffix military-grade qualification and ceramic DIP (JG) package.
Technical Context
The TLV2422MJGB employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ), high input impedance (>10¹² Ω), and no phase inversion when driven to supply rails. Its architecture supports single-supply operation down to 2.7 V while maintaining rail-to-rail output drive into 600-Ω loads.
It is fully characterized across –55°C to 125°C, qualified to MIL-PRF-38535 standards, and features 950 µV max input offset voltage (TLV2422AM variant), 70 dB minimum CMRR, and 80 dB minimum PSRR - enabling precision DC-coupled amplification in harsh-environment industrial and aerospace systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct interface with 3.3-V and 5-V logic rails and battery-backed systems without level-shifting. |
| Supply Current per Channel | 100–150 µA (typ/max at 25°C) - supports multi-year operation in coin-cell–powered IoT sensors and portable instrumentation. |
| Input Offset Voltage | 950 µV max (TLV2422AM spec) - ensures ≤1 mV total error in 12-bit ADC front-ends with gain ≤2. |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying outputs from piezoelectric transducers or pH electrodes. |
| Output Drive Capability | ±50 mA short-circuit current; drives 600-Ω loads - sufficient for telecom line-driver stages and DAC buffer applications. |
| Common-Mode Input Range | 0 V to VDD – 0.8 V - allows direct sensing of ground-referenced signals (e.g., shunt current monitors) without level shifters. |
| Output Voltage Swing | Rail-to-rail (0 V to VDD) - maximizes dynamic range when interfacing with 3.3-V or 5-V SAR ADCs. |
Pinout & Package
Ceramic Dual-In-Line Package (JG), 8-pin, through-hole, hermetically sealed, rated for –55°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail capable; connects directly to ADC input or next-stage filter. |
| 2 | IN1– | Inverting input of Amp 1 - high-impedance node; requires matched trace routing to minimize offset drift. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts signals from high-Z sources (e.g., thermocouples, photodiodes). |
| 4 | VDD– / GND | Negative supply or ground reference - must be low-impedance; decoupling capacitor required near pin. |
| 5 | VDD+ | Positive supply - accepts 2.7–10 V; internal ESD protection rated to ±2 kV HBM. |
| 6 | OUT2 | Amplifier 2 output - independent channel; enables dual-sensor conditioning or differential driver topologies. |
| 7 | IN2– | Inverting input of Amp 2 - electrically isolated from Amp 1 inputs; supports independent feedback networks. |
| 8 | IN2+ | Non-inverting input of Amp 2 - identical electrical characteristics to Pin 3; enables matched dual-channel design. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extends to both rails without output polarity reversal - eliminates need for input clamping diodes in rail-sensing circuits. |
| Rail-to-rail output | Delivers full 0 V to VDD swing at load currents up to ±1 mA - increases effective resolution by ≥1 LSB when driving 12-bit ADCs. |
| Micropower operation | 100 µA/channel typical IDD - reduces thermal drift and enables use in thermally constrained enclosures or sealed modules. |
| Extended temperature range | –55°C to +125°C operation with full parametric guarantee - suitable for engine control units, downhole tools, and avionics. |
| Low input noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level sensor amplification (e.g., strain gauges, RTDs) without requiring external filtering. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333MJGB | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2422MJGB's 2 µV/°C; higher quiescent current (17 µA vs. 100 µA) | Required for sub-µV drift in precision weigh scales; not suitable for multi-year battery life | Select OPA2333MJGB only when long-term DC stability outweighs power budget constraints. |
| LMC6482IMX/NOPB | CMOS input; 1.5 pA IIB (vs. 1 pA); wider supply range (3–16 V); no military temp grade or JG package | Used in commercial test equipment; lacks MIL-PRF-38535 qualification and extended temperature validation | Choose LMC6482IMX/NOPB for cost-sensitive commercial designs where –40°C to 85°C suffices and hermetic packaging is unnecessary. |

FAQ
What is the maximum operating temperature range for TLV2422MJGB?
The TLV2422MJGB is qualified for continuous operation from –55°C to +125°C, with full electrical specifications guaranteed across this range. This rating reflects its MIL-PRF-38535 Class B qualification and ceramic DIP (JG) package construction - making it suitable for under-hood automotive, downhole oil/gas, and avionics applications where ambient extremes exceed commercial-grade limits.
Does TLV2422MJGB support true rail-to-rail input?
No, TLV2422MJGB does not feature rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD – 0.8 V at 5-V supply (0 V to 4.2 V full range), which excludes the positive rail. However, it provides rail-to-rail output swing and avoids phase inversion when inputs approach either supply - a key advantage over standard CMOS op-amps in single-supply configurations.
What is the input offset voltage specification for TLV2422MJGB?
TLV2422MJGB belongs to the TLV2422AM variant group, with a maximum input offset voltage of 950 µV at TA = 25°C and 1800 µV across the full –55°C to 125°C range. This value is explicitly confirmed in the "TLV2422AQ, TLV2422AM" electrical characteristics table (page 8, VDD = 3 V) and applies to the JG-package M-suffix device.
Can TLV2422MJGB drive a 600-Ω load effectively?
Yes, TLV2422MJGB is specifically characterized for 600-Ω load drive capability. The datasheet states "600-Ω Output Drive" in its headline features and confirms rail-to-rail output swing into such loads - enabling direct interface with legacy telecom line receivers, analog phone interfaces, and certain DAC output buffers without external gain stages.
Is TLV2422MJGB pin-compatible with other TLV2422 variants?
Yes, TLV2422MJGB shares identical pinout and footprint with all TLV2422x variants in the JG (ceramic DIP) package, including TLV2422MFK, TLV2422MU, and TLV2422AMJG. All JG-packaged versions use the same 8-pin DIP layout with OUT1, IN1–, IN1+, VDD–/GND, VDD+, OUT2, IN2–, IN2+ assignment - ensuring mechanical and electrical interchangeability within the same package type.
