The **ADTL082ARMZ-R2** is a high-performance, dual-channel, JFET-input operational amplifier (op-amp) manufactured by Analog Devices. It is designed for applications requiring high precision, low noise, and high input impedance. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Number of Channels** | 2 (Dual) | | **Input Type** | JFET-Input | | **Supply Voltage (Max)** | ±18 V (or 36 V single supply) | | **Gain Bandwidth Product** | 5 MHz | | **Slew Rate** | 20 V/µs | | **Input Bias Current** | 10 pA (Typical) | | **Low Noise** | 16 nV/√Hz @ 1 kHz | | **Package Type** | MSOP-8 (ARMZ suffix) | | **Operating Temp** | -40°C to +125°C | --- ### 2. Core Features and Advantages * **JFET Input Technology:** The use of Junction Field-Effect Transistors at the input stage results in extremely low input bias currents. This makes the chip ideal for interfacing with high-impedance sensors or photodiode circuits. * **High Slew Rate:** At 20 V/µs, it can handle rapid changes in input signals without significant distortion, which is critical for pulse processing. * **Wide Supply Range:** It can operate on industry-standard ±15V rails, making it a "drop-in" upgrade for older op-amps like the TL082 or LF353 in many designs. * **Precision Performance:** It offers a lower offset voltage and better thermal stability compared to standard general-purpose JFET op-amps. --- ### 3.
