The MAX1190ECM+D from Maxim Integrated is a 10-bit pipelined ADC integrating two converters in a single 48-TQFP exposed-pad package, each sampling at 120 Msps with simultaneous acquisition. The dual-channel architecture with a 1:1 S/H-to-ADC ratio means both inputs are captured on the same clock edge — no external sample-and-hold alignment needed for I/Q demodulation, dual-channel radar IF processing, or multi-element ultrasound beamforming. It accepts both differential and single-ended inputs and uses a parallel data interface. The analog and digital supplies share a common 3.1 V to 3.6 V range, which simplifies the power rail to a single 3.3 V supply but demands clean decoupling — plan for a low-noise LDO with good PSRR above 10 MHz.
Package and thermal — the exposed pad is not optional
The 48-TQFP exposed pad (7x7 mm) is the primary thermal path. At 120 Msps with both channels active, the die dissipates enough that skipping the pad solder connection or omitting the via array under the pad will push the junction temperature past the rated limit in still air. The tray shipping medium means the parts arrive in anti-static trays, not tape-and-reel — confirm your pick-and-place feeder compatibility if you are buying in production quantities.
ROHS3 compliant. No last-time-buy pressure for new designs.
