KIT ATION EVALU E L B AVAILA
Multichannel, 16-Bit, 200ksps Analog-to-Digital Converters
General Description
The MAX1167/MAX1168 low-power, multichannel, 16bit 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 2.9mA (AVDD = DVDD = +5V) at 200ksps when using an external reference. AutoShutdown™ reduces the supply current to 145µA at 10ksps and to less than 10µA at reduced sampling rates.
