EL8401IUZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL8401IUZ-T7 is a quad-channel, high-speed operational amplifier manufactured by Intersil. It features a -3dB bandwidth of 200MHz and a slew rate of 200V/µs. The device operates on supply voltages ranging from 3V to 5.5V with a low quiescent current of 2mA per channel. It provides rail-to-rail output capability and allows input signals to approach the negative supply rail within 0.15V. The component is housed in a 16-lead QSOP package and is specified for operation across an industrial temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix T7 against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with the 16-lead QSOP footprint during PCB layout. Confirm RoHS compliance status through manufacturer documentation prior to integration. Validate that the operating voltage range aligns with system power rails.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple high-speed channels are required in a compact form factor. The quad configuration reduces board space compared to individual dual or single amplifiers. Consider the rail-to-rail output feature if driving loads close to supply limits. Verify thermal management requirements for the QSOP package under continuous operation.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL8401 belongs to the EL8200/EL8201/EL8401 family of 200MHz rail-to-rail amplifiers. While the EL8200 includes a disable function and the EL8201 offers dual-channel options, the EL8401 specifically provides four channels. This family targets applications requiring high bandwidth and low power in portable and video systems.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the EL8401 include a shutdown or disable pin?

No, the EL8401 does not feature a fast-acting disable or power-down circuit; this function is available only in the EL8200 variant.

What is the minimum input voltage headroom relative to the negative supply?

The inputs can operate down to 0.15V below the VS- (negative supply) rail.
