CS5180 ∆Σ Modulator & 8 kHz to 400 kHz 16-Bit ADC Features 16-Bit Delta-Sigma A/D Converter Fully Differential Input with 4.0 Vpp Range Dynamic Range: 93 dB Spurious Free Dynamic Range: 96 dB Total Harmonic Distortion: -95 dB @ 22 kHz Up to 400 kHz Output Word Rate No Missing Codes Non-Aliasing Low-Pass Digital Filter High Speed 3-Wire Serial Interface Supply Options: - VA+= 5 V, VD+=5 V, 690 mW - VA+= 5 V, VD+=3 V, 368 mW Modulator Output Mode Power Down Mode Description CS5180 is a fully calibrated high-speed ∆Σ analog-to- digital converter, capable of 400 kSamples/second out- put word rate (OWR). The OWR scales with the master clock. It consists of a 5th order ∆Σ modulator, decimation filter, and serial interface. The chip can use the 2.375 V on-chip voltage reference, or an external 2.5 V refer- ence. 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 con- sumption at times of system inactivity. The high speed digital I/O lines have complementary signals to help re- duce 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.
