Configurable mixed-signal IC hosts high-accuracy analogue functions

April 23, 2015 // By Graham Prophet
Silego Technology’s SLG46140V GreenPAK configurable mixed-signal IC (CMIC) contains the company’s 4th generation analogue and digital components in 1.6 x 2.0 mm, 14-pin STQFN.

The SLG46140V is the second member of the 4th generation of GPAK products, with expanded functionality and improved accuracy. In a 1.6 x 2.0 x 0.55 mm 14-pin STQFN, this IC can implement sophisticated mixed-signal circuits in even the most size-constrained products; the device can implement functions such as comparators, ADCs, logic, delays, counters, resets, power sequencing, voltage sensing, and interface circuits while minimising component count, board space, and power consumption.

Development is with GPAK development hardware and the simple GUI interface of GPAK Designer, allowing engineers to quickly and easily implement new designs and respond to changing design requirements. “With the SLG46140V GreenPAK4, we’ve taken the mixed-signal functionality of the SLG46620V and partitioned it into a smaller and less expensive device to address demanding requirements in highly space-constrained designs,” said John McDonald, VP of Marketing.
