Ultra-Low-Power, 45Msps, Dual 8-Bit ADC
DescriptionThe MAX1193 is an ultra-low-power, dual, 8-bit, 45Msps 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 MAX1193 delivers a typical signal-to-noise and distortion (SINAD) of 48.5dB at an input frequency of 5.5MHz and a sampling rate of 45Msps while consuming only 57mW. 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 MAX1193 features three power-down modes to conserve power during idle periods. Excellent dynamic performance, ultra-low power, and small size make the MAX1193 ideal for applications in imaging, instrumentation, and digital communications.
An internal 1.024V precision bandgap reference sets the full-scale range of the ADC to ±0.512V. A flexible reference structure allows the MAX1193 to use its internal reference or accept an externally applied reference for applications requiring increased accuracy.
The MAX1193 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 different logic levels. The MAX1193 is available in a 5mm x 5mm, 28-pin thin QFN package, and is specified for the extended industrial (-40°C to +85°C) temperature range.
For higher sampling frequency applications, refer to the MAX1195-MAX1198 dual 8-bit ADCs. See a parametric table of the complete family of pin-compatible, 8-bit high-speed ADCs.
