Product Summary

The MAX7219CWG+ is a 12-bit, switchedcapacitor, successive-approximation, analog-todigital converter. Each device has three control inputs chip select (CS), the input-output clock (I/O CLOCK), and the address input (DATA INPUT) and is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output. The device allows high-speed data transfers from the host.

Parametrics

MAX7219CWG+ absolute maximum ratings: (1)Supply voltage range, VCC (see Note 1):–0.5 V to 6.5 V ; (2)Input voltage range, VI (any input): –0.3 V to VCC + 0.3 V; (3)Output voltage range, VO:–0.3 V to VCC + 0.3 V; (4)Positive reference voltage: VCC + 0.1 V; (5)Negative reference voltage: -0.1 V; (6)Peak input current: ±20 mA; (7)Peak total input current: ±30 mA; (8)Storage temperature range: –65 to 150℃; (9)Lead temperature 1,6 mm (1/16 inch) from the case for 10 seconds: 260℃.
