MAXIM INTEGRATED PRODUCTS  MAX1190ECM+D  模数转换器, 低功率, 10 bit, 120 MSPS, 单, 3.1 V, 3.6 V, TQFP

The is a dual 10bit, 120Msps, 3.3V, low power ADC with internal reference and parallel outputs in 48 pin TQFP package. It features a fully differential wideband track and hold T/H inputs, driving two ADC. It consumes only 105mW while delivering a typical signal to noise ratio SNR of 59.4dB at an input frequency of 20MHz and a sampling rate of 40Msps. Digital outputs A and B are updated alternating on the rising CHA and falling CHB edge of the clock. The T/H driven input stages incorporate 400MHz -3dB input amplifiers. The converter may also be operated with single ended inputs. In addition to low operating power, IC features a 2.8mA sleep mode as well as a 1µA power-down mode to conserve power during idle periods. It is used in multichannel IF sampling, baseband I/Q sampling & WLAN, WWAN, WLL, MMDS modems, set-top boxes and VSAT terminals.
