The ADA4062-2/ADA4062-4 are low-power, low-input bias current, low input offset voltage, low input drift, high input impedance JFET-input amplifiers.
The ADA4062‑2 (dual) and ADA4062‑4 (quad) are JFET‑input operational amplifiers designed for low power consumption and precision performance. They are suited for power‑control monitoring, active filtering, industrial/process controls, data acquisition, and buffering applications.
Key specifications include a typical input bias current of 50 pA, offset voltage as low as 1.5 mV (B‑grade), slew rate of 3.3 V/µs, CMRR of 90 dB, and supply current of 165 µA per amplifier. The devices operate from ±4 V to ±18 V supplies and are rated for –40 °C to +125 °C. Available in 8‑lead SOIC, 8‑lead MSOP, 10‑lead LFCSP, 14‑lead TSSOP, and 16‑lead LFCSP packages.
