3 Description

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).
