MyMaxim SubscriptionsProduct Details
The MAX1167/MAX1168 low-power, multichannel, 16-bit analog-to-digital converters (ADCs) feature a successive-approximation ADC, integrated +4.096V reference, a reference buffer, an internal oscillator, automatic power-down, and a high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. The MAX1167/MAX1168 operate with a single +5V analog supply and feature a separate digital supply, allowing direct interfacing with +2.7V to +5.5V digital logic.
The MAX1167/MAX1168 consume only 3.6mA (AVDD = DVDD = +5V) at 200ksps when using an external reference. AutoShutdown™ reduces the supply current to 185µA at 10ksps and to less than 10µA at reduced sampling rates.
The MAX1167 includes a 4-channel input multiplexer, and the MAX1168 accepts up to eight analog inputs. In addition, digital signal processor (DSP)-initiated conversions are simplified with the DSP frame-sync input and output featured in the MAX1168. The MAX1168 includes a data-bit transfer input to select between 8-bit-wide or 16-bit-wide data-transfer modes. Both devices feature a scan mode that converts each channel sequentially or one channel continuously.
Excellent dynamic performance and low power, combined with ease of use and an integrated reference, make the MAX1167/MAX1168 ideal for control and data-acquisition operations or for other applications with demanding power consumption and space requirements. The MAX1167 is available in a 16-pin QSOP package and the MAX1168 is available in a 24-pin QSOP package. Both devices are guaranteed over the commercial (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges. Use the MAX1168 evaluation kit to evaluate the MAX1168.
