MAXIM MAX1191 Ultra-Low-Power 7.5Msps Dual 8-Bit ADC handbook
Update: 30 September, 2023
The MAX1191 is an ultra-low-power, dual, 8-bit, 7.5Msps analog-to-digital converter (ADC). The device features two fully differential wideband track-and-hold (T/H) inputs. These inputs have a 440MHz bandwidth and accept fully differential or single-ended signals. The MAX1191 delivers a typical signal-to-noise and dis- tortion (SINAD) of 48.6dB at an input frequency of 1.875MHz and a sampling rate of 7.5Msps while con- suming only 12mW. This ADC operates from a 2.7V to 3.6V analog power supply. A separate 1.8V to 3.6V supply powers the digital output driver. In addition to ultra-low operating power, the MAX1191 features three power-down modes to conserve power during idle peri- ods. Excellent dynamic performance, ultra-low power, and small size make the MAX1191 ideal for applica- tions in imaging, instrumentation, and digital communi- cations. An internal 1.024V precision bandgap reference sets the full-scale range of the ADC to ±0.512V. A flexible reference structure allows the MAX1191 to use its inter- nal reference or accept an externally applied reference for applications requiring increased accuracy. The MAX1191 features parallel, multiplexed, CMOS- compatible tri-state outputs. The digital output format is offset binary. A separate digital power input accepts a voltage from 1.8V to 3.6V for flexible interfacing to dif- ferent logic levels. The MAX1191 is available in a 5mm × 5mm, 28-pin thin QFN package, and is specified for the extended industrial (-40°C to 85°C) applications.
