FEATURES  
DESCRIPTIO  
The LTC®1407-1/LTC1407A-1 are 12-bit/14-bit, 3Msps  
ADCswithtwo1.5Mspssimultaneouslysampleddifferen-  
tial inputs. The devices draw only 4.7mA from a single 3V  
supply and come in a tiny 10-lead MS package. A Sleep  
shutdown feature lowers power consumption to 10µW.  
The combination of speed, low power and tiny package  
makestheLTC1407-1/LTC1407A-1suitableforhighspeed,  
portable applications.  
3Msps Sampling ADC with Two Simultaneous  
Differential Inputs  
1.5Msps Throughput per Channel  
Low Power Dissipation: 14mW (Typ)  
3V Single Supply Operation  
±1.25V Differential Input Range

(LTC1407/LTC1407A)  
2.5V Internal Bandgap Reference with External  
The LTC1407-1/LTC1407A-1 contain two separate differ-  
entialinputsthataresampledsimultaneouslyontherising  
edge of the CONV signal. These two sampled inputs are  
then converted at a rate of 1.5Msps per channel.

APPLICATIO S  
The devices convert –1.25V to 1.25V bipolar inputs differ-  
entially. The absolute voltage swing for CH0+, CH0, CH1+  
and CH1extends from ground to the supply voltage.

Multiphase Motor Control  
I & Q Demodulation  
Industrial Radio  
The serial interface sends out the two conversion results in  
32 clocks for compatibility with standard serial interfaces.
