Product Details
The MAX9644/MAX9645/MAX9646 are small, single comparators, ideal for a wide variety of portable electronics applications such as cell phones, media players, and notebooks that have extremely tight board space and power constraints. These comparators are offered in both a miniature 4-bump UCSP™ package with a 1mm x 1mm footprint (as small as two 0402 resistors) and a 5-pin SOT23 package.
The ICs feature an input voltage range of -0.3V to +5.5V, independent of supply voltage. These devices maintain high impedance at the inputs even when powered down (VCC or VREF = 0V). They also feature internal filtering to provide high RF immunity.
The ICs have an internal 0.2V reference. These devices feature either a push-pull or an open-drain output. They consume only 700nA (max) supply current and operate down to VCC = 1V over the extended -40°C to +85°C temperature range.
Applications
- Cell Phones
- Electronic Toys
- Notebook Computers
- Portable Media Players
- Portable Medical Devices
