Configurable Mixed-signal Matrix with In-System Programmability and Advanced Analog Features

GreenPAK Online Store

Analog PAK Configurable Mixed-signal IC with Operational Amplifiers, Digital Rheostats, EEPROM and a Wide Set of Analog and Digital Macrocells

The SLG47004 builds upon the flexibility of the GreenPAK’s traditional mixed-signal solution by integrating a mix of advanced analog features including Op Amps with programmable bandwidth, 10-bit digital rheostats, analog switches, and a chopper analog comparator. The unique Auto-Trim feature highlights the ability of this GreenPAK device to periodically tune its rheostat value to either compensate for system error sources or reconfigure circuit parameters. The SLG47004 provides dynamic power down control for all analog and digital blocks to optimize power consumption performance. Common applications include sensor interfaces, ADC analog front-ends, configurable amplifiers, tunable filters, and a variety of other analog circuits. This multi-time programmable solution is built into a tiny 3 mm x 3 mm package.
