1 Device Information

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 per amplifier. 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 (SEE) and is ELDRS-free up to 30 krad(Si). Radiation lot acceptance testing (RLAT) for the LMP7704-SP is performed with high dose rate. Condition A as specified in MIL-STD-883, Method 1019. The radiation end point limits for the specified parameters are maintained only for the conditions as specified in MIL-STD-883, Method 1019, Condition A, to a maximum total dose of 30 krad(Si).
