1 / 16 page  Description For processing signals from a sensor or MEMS device, the Smart Programmable Sensor Interface (MSSPSI) is a monolithic CMOS integrated circuit. Small analog signals from a sensor or MEMS are anti-aliased, filtered and amplified before being con- verted into a digital signal output by the MSSPSI. These processing functions are controlled by an external uP through the MSSPSI's on-chip serial interface. The MSSPSI also includes offset adjust, low power modes and an on-chip temperature sen- sor. The input is fed into a low noise amplifier followed by two 6th order Elliptic switched capacitor anti- aliasing filters. The gain of the filter is controllable via the serial interface up to 18 dB (6 dB) steps. The next stage is a 6 pole Butterworth switched capacitor highpass filter, also with up to 18 dB of controllable gain. Following this is a 7th order Elliptic switched capacitor lowpass filter. These inter- nal filters can be bypassed via the serial interface. The 12 bit, 160 kSps A-to-D converter provides a digital output. The MSSPSI operates with a supply voltage from 3.3 VDC up to 5.5 VDC. It is available in a 32 pin LQFP Package with an industrial temperature range.
