MyMaxim SubscriptionsProduct Details
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.
Key Features
- Tiny, 1mm x 1mm x 0.6mm 4-Bump UCSP
- Footprint = Two 0402 Resistors
- Also Available in a 5-Pin SOT23 Package
- Ultra-Low Operating Current (700nA max)
- -0.3V to +5.5V Input Voltage Range
- Internal 0.2V Reference Trimmed to 1% Accuracy
- 15µs Propagation Delay
- -40°C to +85°C Extended Temperature Range
Applications/Uses
- Cell Phones
- Electronic Toys
- Notebook Computers
- Portable Media Players
- Portable Medical Devices

Description
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).
Features
- -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
