General Description

The MAX1167/MAX1168 low-power, multichannel, 16-bit analog-to-digital converters (ADCs) feature a suc-o16-Bit Resolution, ±1 LSB DNL (max)cessive-approximation ADC, integrated +4.096Vo+5V Single-Supply Operation

reference, a reference buffer, an internal oscillator,automatic power-down, and a high-speed SPI /oAdjustable Logic Level (+2.7V to +5.25V)QSPI /MICROWIRE -compatible interface. TheoInput Voltage Range: 0 to VREF

MAX1167/MAX1168 operate with a single +5V analogsupply and feature a separate digital supply, allowingoInternal (+4.096V) or External (+3.8V to AVDD)direct interfacing with +2.7V to +5.5V digital logic.ReferenceThe MAX1167/MAX1168 consume only 2.9mA (AVoInternal Track/Hold, 4MHz Input Bandwidth= +5V) at 200ksps when using an external reference.DD=DVAutoShutdown reduces the supply current to 145µA atDDoInternal or External Clock

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functionaloperation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure toabsolute maximum rating conditions for extended periods may affect device reliability.
