MAX1449EHJ+

The MAX1449EHJ+ is a 10bit, 105Msps, single 3.3V, low power ADC with internal reference in 32 pin TQFP package. This ADC features a fully differential input, a pipelined 10-stage ADC architecture with wideband track and hold (T/H) and digital error correction incorporating a fully differential signal path. It consume only 186mW while delivering a 58.5dB (typ) signal to noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a -3dB 400MHz bandwidth and may be operated with single-ended inputs. In addition to low operating power, it also features a 5µA power-down mode for idle periods. It has parallel, offset binary, CMOS-compatible, three-state outputs that can be operated from 1.7V to 3.6V to allow flexible interfacing. It is used in baseb and IF digitization and digital set-top boxes.
