The MAX1886 is a high-current operational transconductance amplifier. The MAX1886 is ideal for driving the backplane of an active matrix, dot inversion thin film transistor (TFT) liquid crystal display (LCD). The MAX1886's high >500mA peak-current drive capability provides fast response to pulsed load conditions. The MAX1886 is stable from 0.47µF to an unlimited amount of output capacitance.

The MAX1886 is available in the low-profile (1.1mm max) 5-pin Thin SOT23 package and fully specified over the -40°C to +85°C extended temperature range.

Key Features   Applications/Uses
