19-1899; Rev 1; 5/04 www.DataSheet4U.com 12-Bit, 20Msps, 3.3V, Low-Power ADC with Internal Reference General Description The MAX1422 3.3V, 12-bit analog-to-digital converter (ADC) features a fully differential input, pipelined, 12stage ADC architecture with wideband track-and-hold (T/H) and digital error correction incorporating a fully-differential signal path. The MAX1422 is optimized for lowpower, high dynamic performance applications in imaging and digital communications. The converter operates from a single 3.3V supply, consuming only 137mW while delivering a 67dB (typ) signal-to-noise ratio (SNR) at a 5MHz input frequency and a 20Msps sampling frequency. The fully-differential input stage has a small signal -3dB bandwidth of 400MHz and may be operated with single-ended inputs.
