MAX1186ECM+D by Analog Devices

Dual 10-Bit, 40Msps, 3V, Low-Power ADC with Internal Reference and Multiplexed Parallel Outputs


The MAX1186 is a 3V, dual 10-bit analog-to-digital converter (ADC) featuring fully-differential wideband track-and-hold (T/H) inputs, driving two pipelined, nine-stage ADCs. The MAX1186 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-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 the falling (CHB) edge of the clock. The T/H driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with single-ended inputs. In addition to low operating power, the MAX1186 features a 2.8mA sleep mode as well as a 1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADCs. A flexible reference structure allows the use of this internal or an externally derived reference, if desired for applications requiring increased accuracy or a different input voltage range. The MAX1186 features parallel, multiplexed, CMOS-compatible three-state outputs. The digital output format can be set to two's complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing. The MAX1186 is available in a 7mm x 7mm, 48-pin TQFP-EP package, and is specified for the extended industrial (-40°C to +85°C) temperature range. Pin-compatible, nonmultiplexed, high-speed versions of the MAX1186 are also available. Please refer to the MAX1180 data sheet for 105Msps, the MAX1181 data sheet for 80Msps, the MAX1182 data sheet for 65Msps, the MAX1183 data sheet for 40Msps, and the MAX1184 data sheet for 20Msps. For a pin-compatible lower speed version (20Msps) of the MAX1186, please refer to the MAX1185 data sheet.
