MAX749ESA+T Description

Short technical summary and product information.

The MAX749ESA+T is a specialized integrated circuit designed for generating and adjusting negative LCD-bias contrast voltages. It accepts input voltages ranging from 2V to 6V and can digitally adjust the full-scale output voltage in 64 equal steps using an internal DAC. This IC is highly energy-efficient, with a maximum quiescent current of only 60µA, which reduces to under 15µA in shutdown mode, making it ideal for battery-powered and portable devices.

 

The device is housed in a compact 8-pin SOIC package, suitable for surface mounting. It operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance in various environments. The MAX749ESA+T is designed for applications such as notebook computers, PDAs, and portable data-collection terminals where stable and adjustable bias voltages are critical for LCD display quality.

 

Key features include flexible output voltage control via digital input, potentiometer, or PWM signal. Its high switching frequency minimizes the size of external components, contributing to a compact overall solution. The IC drives either an external P-channel MOSFET or a PNP transistor, offering design flexibility.
