General Description

The ADAR7251 is a 16-bit, 4-channel, simultaneous sampling 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 (LNA), a programmable gain amplifier (PGA), an equalizer, a multibit Σ-Δ ADC, and a decimation filter.

The front-end circuitry is designed to allow direct connection to an MMIC output with few external passive components.
