400ksps/300ksps, Single-Supply, Low-Power,  
Serial 12-Bit ADCs with Internal Reference  
4/MAX1285  
General Description  
____________________________Features  
The MAX1284/MAX1285 12-bit analog-to-digital con-  
verters (ADCs) combine a high-bandwidth track/hold  
(T/H), a serial interface with high conversion speed, an  
internal +2.5V reference, and low power consumption.  
The MAX1284 operates from a single +4.5V to +5.5V  
supply. The MAX1285 operates from a single +2.7V to  
+3.6V supply.  
o Single-Supply Operation  
+4.5V to +5.5V (MAX1284)  
+2.7V to +3.6V (MAX1285)  
o
1LSB (max) DNL, 1LSB (max) INL  
o 400ksps Sampling Rate (MAX1284)  
o Internal Track/Hold  
o +2.5V Internal Reference  
o Low Power: 2.5mA (400ksps)  
o SPI/QSPI/MICROWIRE 3-Wire Serial-Interface  
The 3-wire serial interface connects directly to  
SPI™/QSPI™/ MICROWIRE™ devices without external  
logic. The devices use an external serial-interface clock  
to perform successive-approximation analog-to-digital  
conversions.  
Low power, ease of use, and small package size make  
these converters ideal for remote-sensor and data-acqui-  
sition applications or for other circuits with demanding  
power consumption and space requirements. The  
MAX1284/MAX1285 are available in 8-pin SO packages.  
o Pin-Compatible, High-Speed Upgrades to  
MAX1240/MAX1241  
o 8-Pin SO Package  
These devices are pin-compatible, higher-speed ver-  
sions of the MAX1240/MAX1241. Refer to the respec-  
tive data sheets for more information.
