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 distortion (SINAD) of 48.6dB at an input frequency of 1.875MHz and a sampling rate of 7.5Msps while consuming 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 periods. Excellent dynamic performance, ultra-low power, and small size make the MAX1191 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 MAX1191 to use its internal 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 different logic levels. The MAX1191 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.

Product Detail

The MAX1193 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX1191/MAX1192/MAX1193 dual, 8-bit analog-to-digital converters (ADCs). The MAX1191/MAX1192/MAX1193 accept AC- or DC-coupled, differential, or single-ended analog inputs. The digital output produced by the ADC can be easily captured with a user-provided high-speed logic analyzer or data acquisition system. The EV kit operates from a 3.3V analog and a 2.5V digital power supply. The EV kit includes circuitry that generates a clock signal from an AC sine wave signal provided by the user. The EV kit comes with the MAX1193 installed. Order free samples of the pin-compatible MAX1191 or MAX1192 to evaluate these parts.
