GENERAL DESCRIPTION

The MAX74840 is a single-supply, rail-to-rail output

(RRO), junction field effect transistors (JFET) input

operational amplifiers (Op Amps).

The input voltage range includes the negative supply

and the output swings rail-to-rail. This enables the user

to maximize dynamic input range in low voltage, single

supply applications without the need for a separate

negative voltage power supply for ground sense.

Input EMI filters increase the signal robustness in the

face of closely located switching noise sources.

The speed, in terms of bandwidth and slew rate,

increases along with a strong output drive to improve

settling time performance and enables the devices to

drive the inputs of modern single-ended, successive

approximation register (SAR) analog-to-digital

converters (ADCs).

The MAX74840 is specified for operation over the

extended industrial temperature range of −40°C to

+125°C, and operate from 5V to 30V, with specifications

at ±15V. The MAX74840 is available in an 8-lead MSOP

package.
