Features
The MAX1162 low-power, 16-bit analog-to-digital converter (ADC) features a successive-approximation ADC,
automatic power-down, fast 1.1µs wakeup, and a highspeed SPI™/QSPI™/MICROWIRE™-compatible interface. The MAX1162 operates with a single +5V analog
supply and features a separate digital supply, allowing
direct interfacing with +2.7V to +5.25V digital logic.
♦ 16-Bit Resolution, No Missing Codes
At the maximum sampling rate of 200ksps, the
MAX1162 consumes only 2.5mA. Power consumption is
only 12.5mW (AVDD = DVDD = +5V) at a 200ksps (max)
sampling rate. AutoShutdown™ reduces supply current
to 130µA at 10ksps and to less than 10µA at reduced
sampling rates.
♦ SPI/QSPI/MICROWIRE-Compatible Serial Interface
Excellent dynamic performance and low power, combined with ease of use and small package size (10-pin
µMAX and 10-pin DFN) make the MAX1162 ideal for
battery-powered and data-acquisition applications or
for other circuits with demanding power consumption
and space requirements.
♦ +5V Single-Supply Operation
♦ Adjustable Logic Level (+2.7V to +5.25V)
♦ Input Voltage Range: 0 to VREF
♦ Internal Track/Hold, 4MHz Input Bandwidth
♦ Small 10-Pin µMAX or 10-Pin DFN Package
♦ Low Power
