Product details
Overview
TLV2442AMJGB from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage, wide-input-voltage operation. It delivers 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, and 750 µA per channel supply current at 5 V, enabling precision signal conditioning in single-supply sensor interfaces and ADC drivers.
For engineers reviewing the TLV2442AMJGB datasheet, TLV2442AMJGB pinout, TLV2442AMJGB application, or TLV2442AMJGB equivalent, key selection criteria include its –55°C to 125°C military-grade temperature range, 600-Ω output drive capability, no phase inversion behavior, and extended common-mode input range (0 V to 4.25 V min at 5 V).
Technical Context
The TLV2442AMJGB uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining high input impedance (>1 TΩ) and ultra-low input bias current (1 pA typ). Its input stage operates without phase inversion even when driven to the supply rails, eliminating a critical failure mode in high-gain transducer amplifiers.
It features a fully differential input architecture with 1000 GΩ differential and common-mode input resistance, 16 nV/√Hz input voltage noise at 1 kHz, and stable unity-gain operation into 600-Ω loads with 65° phase margin - all characterized across –55°C to 125°C per MIL-PRF-38535 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports battery-powered and industrial 3.3 V/5 V systems without level-shifting. |
| Input Offset Voltage (max) | 950 µV at 25°C - enables sub-mV accuracy in precision DC-coupled sensor front-ends. |
| Gain-Bandwidth Product | 1.8 MHz typ at 5 V - sufficient for anti-aliasing filters and medium-speed data acquisition up to ~100 kSPS. |
| Output Drive Capability | 600-Ω load at full rail-to-rail swing - directly interfaces with legacy telecom line drivers and SAR ADC reference buffers. |
| Common-Mode Input Range | 0 V to 4.25 V (min) at 5 V - accepts inputs down to ground, simplifying single-supply design with unipolar sensors. |
| Supply Current (per channel) | 750 µA typ at 5 V - enables dual-channel operation in space-constrained, low-power remote sensing nodes. |
| Input Bias Current | 1 pA typ - preserves signal integrity from high-impedance sources like piezoelectric transducers and pH electrodes. |
Pinout & Package
Ceramic Dual-In-Line Package (CERDIP), 8-pin, hermetically sealed, qualified for military temperature range (–55°C to 125°C). Pin 1 marked with dot; notch orientation standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail swing supports direct connection to 12-bit ADC inputs without external level shift. |
| 2 | IN1– | Inverting input of Amp 1 - high CMRR (70 dB min) rejects supply noise in single-supply configurations. |
| 3 | IN1+ | Non-inverting input of Amp 1 - 1000 GΩ input resistance prevents loading of high-Z sensor elements. |
| 4 | GND / VDD– | Power return / negative supply - shared reference for both amplifiers; requires low-impedance local decoupling. |
| 5 | VDD+ | Positive supply - accepts 2.7–10 V; internal ESD protection rated to ±2 kV HBM. |
| 6 | IN2+ | Non-inverting input of Amp 2 - independent high-impedance node enables dual-sensor monitoring on one die. |
| 7 | IN2– | Inverting input of Amp 2 - matched to IN1– for consistent common-mode rejection across channels. |
| 8 | OUT2 | Amplifier 2 output - identical AC/DC specs to OUT1; supports differential output stages or independent signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Eliminates output latch-up when common-mode input reaches supply rails - critical for overvoltage-tolerant sensor interfaces. |
| Rail-to-rail output | Swings within 100 mV of VDD+ and GND at 5 mA load - maximizes dynamic range in 3.3 V or 5 V ADC driver applications. |
| Extended common-mode range | 0 V to VDD–1.3 V at full temperature range - enables direct interfacing with 0–5 V industrial sensors without resistor dividers. |
| Low input noise | 16 nV/√Hz at 1 kHz - preserves SNR in low-level signal chains such as strain gauge bridges and thermopile amplifiers. |
| MIL-PRF-38535 qualification | Qualified for high-reliability aerospace and defense systems with full parametric testing at extremes of –55°C and 125°C. |

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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2442AMJGB's 2 µV/°C; higher 350 µA supply current per channel. | Better long-term DC stability in precision weigh scales; less suitable for wide-temp military use due to only –40°C to 125°C rating. | Select OPA2333AIDR when microvolt-level drift over time is critical and military temp range is not required. |
| LMV722MMX/NOPB | Lower 1.2 MHz GBW; 1.25 mA supply current; only rated for –40°C to 125°C; no MIL-PRF qualification. | Suitable for commercial-grade portable medical devices but lacks the reliability validation for aerospace or defense deployments. | Choose LMV722MMX/NOPB for cost-sensitive consumer applications where military qualification and 600-Ω drive are unnecessary. |
Compared with OPA2333AIDR and LMV722MMX/NOPB, the TLV2442AMJGB uniquely combines MIL-PRF-38535 qualification, guaranteed 600-Ω drive, and –55°C to 125°C operation - making it the only option validated for high-reliability embedded systems where environmental robustness and output strength are non-negotiable.

FAQ
What is the maximum operating temperature range for TLV2442AMJGB?
The TLV2442AMJGB is specified for continuous operation from –55°C to 125°C and is fully tested per MIL-PRF-38535 requirements across this range. Electrical parameters including input offset voltage, CMRR, and output drive are guaranteed at both extremes, making it suitable for under-hood automotive, avionics, and downhole industrial applications where thermal resilience is mandatory. This exceeds the –40°C to 125°C range of commercial-grade alternatives like the LMV722MMX/NOPB.
Does TLV2442AMJGB support true rail-to-rail input operation?
No, the TLV2442AMJGB features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from VDD– (GND) to VDD+ – 1.3 V at full temperature range, meaning it accepts inputs down to ground but cannot swing fully to the positive rail. For example, at 5 V supply, the usable input range is 0 V to 3.7 V. This distinguishes it from true rail-to-rail input/output amplifiers such as the OPA2333AIDR, which achieves VDD– to VDD+ input range but at higher cost and power.
Can TLV2442AMJGB drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, the TLV2442AMJGB is explicitly characterized to deliver full rail-to-rail output swing into a 600-Ω load - a key differentiator versus earlier rail-to-rail op-amps. At 5 V supply and 25°C, VOH ≥ 4 V and VOL ≤ 0.8 V at ±5 mA output current, meeting telecom line-driving requirements. This capability is verified across –55°C to 125°C and eliminates the need for external output transistors in legacy analog interface designs.
What is the input offset voltage specification for TLV2442AMJGB?
The TLV2442AMJGB has a maximum input offset voltage of 950 µV at 25°C and 1600 µV across its full –55°C to 125°C operating range. This is guaranteed for the "A" grade variant (denoted by "A" in TLV2442A), distinguishing it from the standard TLV2442 (2.5 mV max). The low offset enables accurate DC-coupled amplification in precision sensor interfaces such as strain gauge bridges and RTD measurement circuits without requiring frequent system calibration.
Is TLV2442AMJGB pin-compatible with other devices in the TLV244x family?
Yes, the TLV2442AMJGB shares the same 8-pin CERDIP (JG) package pinout as all TLV2442 variants, including TLV2442CD, TLV2442ID, and TLV2442AQD. All dual-channel members use identical pin assignments: OUT1, IN1–, IN1+, GND, VDD+, IN2+, IN2–, OUT2. This allows drop-in replacement across temperature grades and offset grades within the same package, provided the application's VIO, temperature, and reliability requirements align with the selected variant.
