Product details
Overview
TLC2252AMJGB from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in a 8-pin ceramic DIP (JG) package, rated for –55°C to 125°C operation. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 850 µV max input offset voltage at 25°C - enabling precision signal conditioning in battery-powered aerospace and military systems.
For engineers reviewing the TLC2252AMJGB datasheet, TLC2252AMJGB pinout, TLC2252AMJGB application, or TLC2252AMJGB equivalent, key selection criteria include its rail-to-rail output swing, ultra-low input bias current (1 pA typ), single- or split-supply compatibility (±2.2 V to ±8 V), and qualification for high-reliability automotive and military environments.
Technical Context
The TLC2252AMJGB uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining micropower operation. Its input stage includes high-impedance CMOS transistors enabling 1 pA typical input bias current and common-mode input range extending to the negative rail.
This device is fully specified across –55°C to 125°C with guaranteed 850 µV max input offset voltage and 70 dB min common-mode rejection ratio. It supports both single-supply (e.g., 5 V) and split-supply (e.g., ±5 V) configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 35 µA per channel - enables multi-year operation on coin-cell batteries in remote sensing nodes. |
| Input Offset Voltage | 850 µV max at 25°C - ensures <1 LSB error when driving 12-bit ADCs with 2.5 V reference. |
| Input Bias Current | 1 pA typical - preserves signal integrity from high-impedance sources like piezoelectric sensors. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - four times lower than legacy micropower CMOS op-amps, critical for low-level analog front-ends. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs without level-shifting circuitry. |
| Operating Temp Range | –55°C to 125°C - qualified for MIL-PRF-38535 Class B and Q-Temp automotive applications. |
| Common-Mode Input Range | Includes negative rail - allows direct interfacing with ground-referenced transducers in single-supply systems. |
Pinout & Package
Ceramic Dual-In-Line Package (JG), 8-pin, through-hole, hermetically sealed, suitable for high-reliability military and aerospace PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA; rail-to-rail swing supports direct ADC interface. |
| 2 | IN1– | Inverting input - high-impedance node (10¹² Ω) minimizes loading of sensor sources. |
| 3 | IN1+ | Non-inverting input - accepts signals down to VDD–, enabling true single-supply operation. |
| 4 | VDD– / GND | Negative supply or ground reference - common return for both amplifiers and bias network. |
| 5 | VDD+ | Positive supply - operates from ±2.2 V to ±8 V; total supply current ≤150 µA over full temperature range. |
| 6 | OUT2 | Amplifier 2 output - independent rail-to-rail output; no crosstalk above 70 dB CMRR. |
| 7 | IN2– | Inverting input - matched to IN1– for differential gain stages with <1 mV input offset mismatch. |
| 8 | IN2+ | Non-inverting input - identical electrical characteristics to IN1+; supports dual-channel instrumentation topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of both rails under 50 µA load - eliminates need for external level shifters in 3.3 V or 5 V data acquisition systems. |
| Ultra-low input bias current | 1 pA typical - prevents signal attenuation and DC drift in >100 MΩ source impedance circuits (e.g., pH electrodes). |
| Low-noise architecture | 19 nV/√Hz at 1 kHz - enables detection of sub-mV signals in medical ECG front-ends without additional filtering. |
| Single- and split-supply support | Fully characterized at 5 V and ±5 V - simplifies design reuse across portable (single) and test equipment (dual) platforms. |
| MIL-PRF-38535 compliance | Qualified per Class B screening - guarantees burn-in, temperature cycling, and hermeticity for space-grade and defense avionics use. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLC2252AMJGB's 0.5 µV/°C; higher quiescent current (17 µA vs. 35 µA per channel) | Used in precision weigh scales and industrial DAC buffers where long-term drift dominates; not qualified for –55°C operation | Select OPA2333AIDR only if sub-µV drift over temperature is required and military temp range is unnecessary. |
| LMC6082IMX/NOPB | Higher input bias current (25 fA vs. 1 pA); wider supply range (±1.5 V to ±8 V); no MIL-qualified variant available | Preferred in commercial medical analyzers and lab equipment where ultra-low bias is secondary to cost and availability | Choose LMC6082IMX/NOPB for cost-sensitive designs needing rail-to-rail I/O but lacking military environmental requirements. |
Compared with OPA2333AIDR and LMC6082IMX/NOPB, the TLC2252AMJGB uniquely combines MIL-PRF-38535 Class B qualification, –55°C operation, and 1 pA input bias - making it irreplaceable in sealed, uncooled aerospace telemetry systems where leakage and thermal cycling dominate failure modes.

FAQ
What is the maximum operating temperature range for the TLC2252AMJGB?
The TLC2252AMJGB is rated for continuous operation from –55°C to 125°C. This extended range is validated per MIL-PRF-38535 Class B screening, including temperature cycling, steady-state life testing, and hermeticity verification - confirming suitability for engine bay, avionics bay, and space payload applications where ambient extremes exceed commercial grade limits.
Does the TLC2252AMJGB support single-supply operation?
Yes, the TLC2252AMJGB fully supports single-supply operation from 4.4 V to 16 V. Its common-mode input voltage range includes the negative rail (GND), and its rail-to-rail output swings within 10 mV of both supply rails - enabling direct interfacing with 3.3 V or 5 V ADCs without level-shifting circuitry or dual supplies.
What is the input offset voltage specification for the TLC2252AMJGB?
The TLC2252AMJGB has a maximum input offset voltage of 850 µV at 25°C, and ≤1000 µV across its full –55°C to 125°C operating range. This is guaranteed for the "A" grade variant (TLC2252A) and confirmed in the SLOS176D datasheet revision March 2001, Table 14, under "TLC2252AI / TLC2252AI" columns.
Is the TLC2252AMJGB pin-compatible with standard industry dual op-amps?
No - the TLC2252AMJGB uses an industry-standard 8-pin DIP pinout (1:OUT1, 2:IN1–, 3:IN1+, 4:VDD–/GND, 5:VDD+, 6:OUT2, 7:IN2–, 8:IN2+), matching generic dual op-amp layouts such as LM747 and TL072. However, its rail-to-rail output and ultra-low bias current require careful review of feedback network stability and PCB leakage paths before drop-in replacement.
What packaging and screening does the 'M' and 'JG' suffix indicate for the TLC2252AMJGB?
The 'M' suffix denotes military temperature range (–55°C to 125°C) and compliance with MIL-PRF-38535 Class B requirements, including burn-in and hermeticity testing. The 'JG' suffix specifies an 8-pin ceramic dual-in-line package with glass-sealed leads - providing superior moisture resistance, thermal stability, and long-term reliability versus plastic packages in high-humidity or vacuum environments.
