Description

CS5180 is a fully calibrated high-speed analog-todigital converter, capable of 400 kSamples/second output word rate (OWR). The OWR scales with the master clock. It consists of a 5th order modulator, decimation filter, and serial interface. The chip can use the 2.375 V on-chip voltage reference, or an external 2.5 V reference. The input voltage range is 1.6 * VREFIN Vpp fully differential. Multiple CS5180s can be fully synchronized in multi-channel applications with a SYNC signal. The part has a power-down mode to minimize power consumption at times of system inactivity. The high speed digital I/O lines have complementary signals to help reduce radiated noise from traces on the PC board. The CS5180 can also be operated in modulator-only mode which provides the delta-sigma modulator bitstream as the output.
