MAX19777  
3Msps, Low-Power, Serial 12-Bit ADC  
General Description  
Benefits and Features  
3Msps Conversion Rate, No Pipeline Delay  
12-Bit Resolution  
The MAX19777 is a 12-bit, compact, high-speed,  
lowpower, successive approximation analog-to-digital  
converter (ADC). This high-performance ADC includes a  
high dynamic range sample-and-hold, as well as a high-  
speed serial interface.  
2-Channel, Single-Ended Analog Inputs  
Low-Noise 72.5dB SNR  
2.2V to 3.3V Supply Voltage  
The MAX19777 features dual, single-ended analog inputs  
connected to the ADC core using a 2:1 MUX.  
Low Power  
This ADC operates from a 2.2V to 3.3V supply and  
consumes only 6.2mW at 3Msps. The device includes  
a full power-down mode and fast wake up for optimal  
power management and a high-speed 3-wire serial  
interface. The 3-wire serial interface directly connects to  
• 6.2mW at 3Msps  
Very Low Power Consumption at 2.5μA/ksps  
● 2μA Power-Down Current  
● SPI/QSPI/MICROWIRE-Compatible Serial Interface  
8-Pin, 0.857mm x 1.431mm WLP Package  
Wide -40°C to +125°C Operation  
®
SPI, QSPI™, and MICROWIRE devices without external  
logic.  
Excellent dynamic performance, low voltage, low power,  
ease-of-use, and small package size make this converter  
ideal for portable, battery-powered data-acquisition  
applications, as well as for other applications that demand  
low power consumption and minimal space.  
Applications  
Data Acquisition  
Portable Data Logging  
Medical Instrumentation  
Battery-Operated Systems  
Communication Systems  
Automotive Systems  
This ADC is available in an 8-pin wafer-level package  
(WLP). This device operates over the -40°C to +125°C  
temperature range.
