Radiation-tolerant, 11-MHz, low-noise, precision rail-to-rail output JFET amplifier

The OPA4H014-SEP is a low-power JFET input operational amplifier (op amp) that features good drift and low input bias current. With an input range that includes V– and a rail-to-rail output, designers can take advantage of the low-noise characteristics of JFET amplifiers while interfacing to single-supply, precision analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

The OPA4H014-SEP achieves 11‑MHz unity-gain bandwidth and 20-V/µs slew rate, while consuming only 1.8 mA (typical) of quiescent current. This device runs on a single 4.5‑V to 18‑V supply or dual ±2.25‑V to ±9‑V supplies.

The op amp is built in a plastic, 14‑pin, TSSOP package with radiation hardness up to 43 MeV•cm2/mg (SET) and is ELDRS free up to 30 krad(Si).
