MAXIM INTEGRATED PRODUCTS  MAX1186ECM+D  模数转换器, 低功率, 10 bit, 40 MSPS, 单, 2.7 V, 3.6 V, TQFP

The is a dual 10bit, 40Msps, 3V low power ADC with internal reference and multiplexed parallel outputs in 48 pin TQFP package. It features fully differential wideband track and hold T/H inputs driving two pipelined nine-stage 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, I/Q channel digitization, ultrasound & instrumentation.
