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.

Evaluation Kits for the MAX9644, MAX9645, and MAX9646

Features and Benefits

  • -0.3V to +5.5V Input Voltage Range
  • +1V to +5.5V VCC Range
  • +0.2V Internal Reference Voltage
  • Evaluates 4-Bump UCSP and Optional 5-Pin SOT23 Packages
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Detail

The MAX9644/MAX9645/MAX9646 evaluation kits (EV kits) are fully assembled and tested PCBs that evaluate the MAX9644/MAX9645/MAX9646 single comparators. All EV kits have a common internal reference voltage of +0.2V, operate from a +1V to +5.5V power supply (VCC), and have a common -0.3V to +5.5V input voltage (IN) range.

The EV kits are configured to evaluate both the 4-bump UCSP™ (installed) and an optional 5-pin SOT23 (to do so, request a free MAX9644/MAX9645/MAX9646 SOT23 IC sample when ordering the EV kits).

Applications

  • Cell Phones
  • Electronic Toys
  • Notebook Computers
  • Portable Media Players
  • Portable Medical Devices
