Product details
Overview
TLC2262AMJGB from Texas Instruments is a dual rail-to-rail output operational amplifier in ceramic DIP (JG) package, rated for –55°C to 125°C operation with maximum input offset voltage of 950 µV at 25°C, 500 µA max supply current, and 12 nV/√Hz typical input voltage noise at 1 kHz - used in precision analog signal conditioning for high-impedance sensors and ADC interfacing in aerospace and military systems.
For engineers reviewing the TLC2262AMJGB datasheet, TLC2262AMJGB pinout, TLC2262AMJGB application, or TLC2262AMJGB equivalent, this page delivers verified electrical specs, JG-package terminal mapping, automotive-grade reliability context, and direct alternatives for high-reliability analog front-end design under extended temperature and radiation-tolerant requirements.
Technical Context
The TLC2262AMJGB implements Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current (1 pA typ) and low noise - enabling accurate amplification of microvolt-level signals from piezoelectric transducers or strain gauges without loading effects.
It operates across ±2.2 V to ±8 V dual supplies or 4.4 V to 16 V single supply, with common-mode input range extending to the negative rail and full characterization at both 5 V and ±5 V - supporting flexible integration into mixed-signal systems requiring wide dynamic range and low-power operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 500 µA max per amplifier - enables battery-powered or thermally constrained designs without sacrificing ac performance. |
| Input Offset Voltage | 950 µV max at 25°C (TLC2262A grade) - ensures <1 LSB error when driving 12-bit ADCs with 5 V reference. |
| Input Bias Current | 1 pA typ - preserves signal integrity in >1 GΩ source impedance applications like pH electrodes or photodiode preamps. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - supports low-noise amplification of small-signal transducers without external filtering. |
| Output Swing | Rail-to-rail - delivers full 0–5 V or ±4.8 V output range into 50 kΩ load, maximizing ADC utilization. |
| Slew Rate | 0.55 V/µs typ - sufficient for <100 kHz small-signal bandwidth in sensor interface and active filter stages. |
| Gain-Bandwidth Product | 0.73 MHz - enables stable unity-gain buffers and low-Q active filters with predictable phase margin (57°). |
Pinout & Package
Ceramic Dual-In-Line Package (JG), 8-pin, hermetically sealed, qualified for high-reliability military and aerospace use. Pin 1 identified by dot; pins 1–4 and 5–8 form two independent op-amp sections.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 Output | Delivers rail-to-rail buffered output; requires no pull-up/down for ADC interface. |
| 2 | Amplifier 1 Inverting Input | High-impedance node (10¹² Ω); sensitive to PCB leakage - guard ring recommended. |
| 3 | Amplifier 1 Non-Inverting Input | Accepts common-mode voltages down to VDD–; enables single-supply sensor biasing. |
| 4 | VDD– / Ground | Power return for both amplifiers; must be low-inductance connection to minimize PSRR degradation. |
| 5 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm. |
| 6 | Amplifier 2 Non-Inverting Input | Independent input path; identical specs to Pin 3 - supports dual-channel synchronous sensing. |
| 7 | Amplifier 2 Inverting Input | Matches Pin 2 performance; usable for differential input configurations with matched feedback networks. |
| 8 | Amplifier 2 Output | Electrically isolated from Pin 1; allows independent gain/phase tuning per channel. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277UA | Higher precision (10 µV VIO), lower noise (8 nV/√Hz), but 1.5 mA supply current and not rated below –40°C. | Better for lab-grade instrumentation; unsuitable for extended-temp embedded systems. | Select when ultra-low offset dominates over power and temperature range. |
| LMC6482IMX | Similar 1 pA Ibias and rail-to-rail output, but only rated to 125°C (not –55°C), and higher 25 nV/√Hz noise. | Acceptable for industrial controls; lacks MIL-PRF-38535 qualification and hermetic sealing. | Select when cost sensitivity outweighs radiation tolerance and extreme temperature needs. |
Compared with OPA2277UA and LMC6482IMX, the TLC2262AMJGB uniquely balances military-grade temperature range (–55°C to 125°C), hermetic JG packaging, sub-1 mV offset, and micropower consumption - making it irreplaceable in space-constrained, high-reliability analog signal chains where thermal cycling and long-term stability are non-negotiable.
