General Description
The MAX1421 is a +3.3V, 12-bit analog-to-digital converter (ADC), featuring a fully-differential input, pipelined, 12-stage ADC architecture with wideband track-and-hold (T/H) and digital error correction incorporating a fully-differential signal path. The MAX1421 is optimized for low-power, high-dynamic performance applications in imaging and digital communications.
