The ADS5433 is a 14 bit 80 MSPS analog-to-digital converter (ADC) that operates from 5 V and 3.3 V supplies while providing 3.3 V CMOS compatible digital outputs. The ADS5433 is optimized for spurious-free dynamic range (SFDR). Pin-compatible to the ADS5423, ADS5424, and AD6644/45, the ADS5433 provides enhanced SFDR for input frequencies up to 100 MHz. At 80 MSPS, SFDR is typically 96.5 dBc and is guaranteed to 91 dBc over the industrial temperature range (-40C to 85C) with a -1 dBFS 30 MHz input signal. The ADS5433 input buffer isolates the internal switching of the on-chip Track and Hold (T&H) from disturbing the signal source. A 2.2 VPP input range and internal reference generator simplify system design. The ADS5433 is available in a 52 pin HTQFP package and is built on Texas Instrument's complementary bipolar process (BiCom3).
