MAX9614/MAX9616

Low-Power Single/Dual, Rail-to-Rail Op Amps

19-5302; Rev 0; 8/10

Typical Application Circuit

General Description

The MAX9614/MAX9616 are low-power precision op

amps that feature precision MOS inputs.

These devices are ideal for a large number of signal pro-

cessing applications such as photodiode transimped-

ance amplifiers and filtering/amplification of a wide

variety of signals in industrial equipment. The devices

also feature excellent RF immunity, making them ideal for

portable applications.

The MAX9614/MAX9616 are capable of operating from

a 2.5V to 5.5V supply voltage over the -40NC to +125NC

automotive temperature range.

Both singles and duals are available in tiny SC70 pack-

ages. The MAX9614 features an active-low shutdown pin.

MAX9614/MAX9616 Low-Power Single/Dual, Rail-to-Rail Op Amps Detailed Description The MAX9614/MAX9616 are low-power op amps ideal for signal processing applications due to the devices’ high precision and CMOS inputs. The MAX9614 also features a low-power shutdown mode that greatly reduces quiescent current while the device is not operational. The MAX9614/MAX9616 self-calibrate on power-up to eliminate effects of temperature and power-supply variation.
