MAX1185

19-2175; Rev 3; 5/11 MAX1185 Dual 10-Bit, 20Msps, 3V, Low-Power ADC with Internal Reference and Multiplexed Parallel Outputs General Description The MAX1185 is a 3V, dual 10-bit analog-to-digital converter (ADC) featuring fully-differential wideband trackand-hold (T/H) inputs, driving two pipelined, nine-stage ADCs. The MAX1185 is optimized for low-power, high dynamic performance applications in imaging, instrumentation, and digital communication applications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 105mW while delivering a typical signal-tonoise ratio (SNR) of 59.5dB at an input frequency of 7.5MHz and a sampling rate of 20Msps. 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 converters may also be operated with singleended inputs. In addition to low operating power, the MAX1185 features a 2.8mA sleep mode as well as a 1µA...
