Product Description

The ADAR7251WBCSZ is a 4-channel 16-bit simultaneous sampling continuous time data acquisition Analog-to-digital Converter (ADC) designed especially for applications such as automotive LSR-FMCW or FSK-FMCW radar systems. Each of the four channels contains a low noise amplifier, a programmable gain amplifier, an equalizer, a multi-bit sigma-delta ADC and a decimation filter. The front-end circuitry is designed to allow direct connection to an MMIC output with few external passive components. The ADC eliminates the need for a high order anti-aliasing filter, driver op amps and external bipolar supplies. The ADC also offers precise channel-to-channel drift matching. The ADC features an on-chip phase-locked loop that allows a range of clock frequencies for flexibility in the system. The CONV_START input and DATA_READY output signals synchronize the ADC with an external ramp for applications such as FSK-FMCW radar.
